Overview

Microgeneration systems such as Solar PV and small wind turbines are at their most efficient when the generated energy is consumed on-site rather than exporting it to the grid. This is what we call ‘self-consumption’. zappi is a Mode 3 charging station, compatible with all electric vehicles that comply with EN 62196 and EN 61851-1 plug-in electric vehicle standards. zappi works like any regular charging point but has special ECO charging modes that will benefit homeowners with grid-tied microgeneration systems e.g. wind or solar generation. Two special ECO charging modes automatically adjust charging current in response to on-site generation and household power consumption. In FAST charge mode, zappi operates like an ordinary EV charger. A grid current sensor (supplied) simply clips around the incoming supply cable and is used to monitor excess power. When using the special ECO charge modes, zappi will automatically adjust the charge rate in response to available surplus.

Display

1.| Import / Export Power| The power being either imported or exported from or to the grid (kW). The direction of the arrows indicates if the property is currently importing power (left) or exporting power (right).

The size of the arrows is proportionate to the level of power being imported / exported, When the property is neither importing or exporting power the figure will be 0.0kW and there will no animated arrows. The property is then said to be ‘in balance’.

---|---|---
2.| House Load Power| The power that the property is currently using in kW. _( Note : This is displayed only when the Generation Sensor is installed directly to a CT input or a harvi_ or other myenergi device)
3.| Status Text| The current status is displayed here (see Status Screens)
4.| Generation Power| The power being generated at this time in kW. _( Note : This is displayed only when the CTs are installed either hard wired to the CT inputs of the_ zappi or wirelessly to a harvi or other myenergi device)
5.| Lock Icon| Operation lock is active.
6.| Date & Time| The current date and time.
7.| Mode Icons| These icons indicate that the import limiting is active (house), Demand Side Response (~) or the eSense input is live (e)
8.| zappi Icon| If you see wavy lines above the zappi icon, the unit is thermally limiting! The output power is temporarily reduced.
9.| Charge Mode| Shows the selected Charging Mode; FAST, ECO or ECO+ (see Charging Modes)
---|---|---
10.| Charge Delivered to EV| The accumulated charge energy that has been sent to EV in this charge session.
11.| Current Charging Power| When the EV is charging, arrows will show here along with the charging power in kW.
12.| Green Level of Last Charge| This is the percentage of ‘Green’ energy for the last charge session, this is shown at the end of a charge or when the EV is unplugged.

Status Screens

EV Disconnected

• The EV is not connected to zappi. In this example the last charging session delivered 20.8kWh of energy to the EV and 80% of that energy came from the solar panels.

Waiting for Surplus

zappi is waiting for sufficient surplus power from the microgeneration system. This screen will be shown in ECO+ mode as it is only in this mode that charging will stop if there is not enough surplus power. The house in the centre is straight-faced as grid electricity is being used by the house (0.9kW in the example shown).

Surplus
Enough surplus is available and zappi is about to charge the EV. A timer is decremented and can be set in the charge settings (ECO+ mode only).

Waiting for EV
zappi is waiting for the EV to respond; the EV is not ready to accept charge.

Charge Delayed

• The charging session has been delayed by the EV because a scheduled charge has been set in the vehicle.

Paused
zappi is paused for a few seconds in order to limit the start/stop frequency during ECO+ mode charging.

Chaging
The EV is charging. In this example the car is charging in ECO+ mode at 1.6kW, there is no import or export from the grid (0.0kW) and the EV battery has charged by 8.9kWh since the car started.

Charge Complete
The EV is fully charged. The charge energy used during the last charge is displayed at the bottom right (20.0kWh in this case) and the ‘green contribution’ is also shown (40% in this example).

Restart
zappi is performing a restart sequence. This may happen with some EVs that need to be ‘woken up’ to start charging after a pause in the charge. The charge should start immediately afterward, otherwise the “Charge Delayed” message will appear.

Stopping
zappi is about to stop the EV charging

Charging Modes

zappi has three different charging modes and a “STOP” mode which can be selected simply by pressing the and buttons when the main screen is showing. The charge mode can be changed before or during a charge. Regardless of the charge mode, all the surplus electricity is used. zappi’s special eco charge modes limit the amount of grid electric used. Below is the explanation of each charging mode.

Charges at the fastest rate
Fast Mode will charge the EV at the fastest rate and will import grid electricity if there is insufficient surplus generated power. The actual charge rate is dependent on the EV’s onboard charger and the grid supply voltage. Some vehicles can charge at 11kW or 22kW on a 3-Phase zappi, but many EV’s have lower charge rates. The maximum charge rate for the single phase zappi is 7kW.

Adjusts the charge rate to limit the use of grid electricity
The charge rate is continuously adjusted, in response to changes in generation or power consumption elsewhere in the home, thereby minimising the use of grid power. Charging will continue until the vehicle is fully charged, using available surplus power. If at any time, the available surplus power falls below 1.4kW, the shortfall will be drawn from the grid.

Note: The EV charging standard does not support below 1.4kW.

Adjusts the charge rate to limit the use of grid electricity and will pause the charge if there is too much or any grid electricity being used (Set-up Dependant)
The charge rate is continuously adjusted, in response to changes in generation or power consumption elsewhere in the home, thereby minimising the use of grid power. Charging will pause if there is too much imported power, continuing only when there is enough surplus power available. The surplus power threshold at which the charge will start or stop can be set using Min Green Level in the ECO+ Settings of the Charge Settings menu. The actual green contribution percentage is shown when the charge is complete or when the zappi has been disconnected from the EV. It is possible to charge the EV using only surplus renewable power, if there is sufficient surplus power available and a boost option has not been set. (Please note: The EV charging standard does not support charging below 1.4kW) Example: when zappi is set to a Min Green Level of 100% you will need in excess of around 1.4kW of surplus energy available to start the charge. If the surplus falls below the 1.4kW threshold the charge will pause until the threshold is once again met. After a short delay zappi will resume charge. If preferable, you can set the zappi to share power from the grid and a generation source to ensure a charge is always maintained. For example, the Min Green Level could be set to 75%. A charge will then start when there is a surplus of 1.05kW, taking a further 0.35kW from the grid. It is worth noting that this is only required to start a charge. If a higher amount of surplus becomes available it will be consumed, resulting in less being drawn from the grid.

The output from zappi is turned off
In STOP mode zappi will not charge your EV. This includes the boost modes and timed boost. zappi will continue to measure power and communicate with the other myenergi devices.

Manual Boost

The Manual Boost function can only be used when charging in ECO or ECO+ mode. When boosting, the charge rate is set to maximum (just like FAST mode), until a set amount of energy has been stored in the EV’s battery. After which, zappi will revert to ECO or ECO+ mode. This function is useful if you arrive home with an almost flat battery and would like to charge the vehicle immediately to ensure there is enough charge for a short trip if needed. The amount of energy delivered to the EV during the boost charge can be changed in the Charge Settings/Boost menu. When in ECO or ECO+ mode, each press of the button will cycle through the boost options as illustrated below:

Activating Boost

1. When charging in ECO or ECO+ mode, press + until BOOST is shown.
2. The boost will start after a couple of seconds and the display will show the remaining boost energy

The boost duration can be altered in the Charge Settings/Manual Boost menu option.

Cancelling Boost
The boost can be cancelled by pressing + until Cancel Boost is shown.

Smart Boost

The Smart Boost function will charge the EV with a minimum kWh figure by a set time. Smart Boost is available only in ECO and ECO+ modes.

• The Smart Boost function does not bring the battery to a certain state of charge. The target kWh is only the energy added during the charging session.

When in ECO or ECO+ mode, each press of the button will cycle through the boost options as illustrated below:

Example: It’s a sunny Sunday and you wish to ensure there is enough charge in the EV to get to work in the morning (e.g. 15kWh), but in the meantime, you want to use the surplus energy from the PV system to charge the car, so you choose to use ECO+ mode. At sunset there was only 10kWh of charge accumulated. However, because you activated Smart Boost, and set the time you needed to leave for work, zappi automatically boosted the charge in the night to top up the battery to the required 15kWh by 7am.

Activating Smart Boost

1. When charging in ECO or ECO+ mode, press until SMART BOOST is shown.
2. The SMART BOOST icon will show including the target time and the pre-set energy amount.
3. zappi will then test the EV for a few seconds, to determine the maximum charge rate.
4. The boost will start at the latest possible time to achieve the set energy amount, if the current charge session has already accumulated enough energy, the boost will not be required and so will not operate.

The required energy and target time can be altered only when Smart Boost is not active. These settings are in the Charge Settings/Smart Boost menu option.

Cancelling Boost
The boost can be cancelled by pressing + until Cancel Boost is shown.

Programming the Smart Boost Values

1. From the main screen, press to enter Main Menu
2. Select Smart Boost from within the Charge Settings menu. The SMART BOOST screen is then shown
3. The boost can now be edited: Use buttons to edit the target time and amount of charge (kWh) that is required
4. Use + the to move to the next value, and the to return to the main screen once the required Smart Boost parameters have been set

Boost Timer

When using ECO or ECO+ charge modes, zappi can be programmed to ‘boost’ the current charge at certain times. When boosting, the charge rate is set to maximum (just like FAST mode), regardless of the amount of available surplus power. This means that power may be drawn from the mains grid supply during boost times.

• There are four editable time slots which can be set to operate for certain days of the week.
• Setting the duration to 0h00 will make the boost inactive.

Programming Boost Times

1. From the main screen, press to enter Main Menu
2. Select Boost Timer from within the Charge Settings menu. The BOOST TIMER screen is then shown.
3. The boost can now be edited: Use buttons to highlight the time slot you wish to change. The lower screenshot shows the start hour being edited:
4. Alter the start hour with the  buttons and then press + to move to minutes.
5. Edit the duration in the same way and then press + again to edit the days of the week you want the boost to be active for. Each day of the week can be toggled on/off with  buttons. Press + to go to the next day. Pressing + on the last day (Sunday) will confirm the boost time slot and the whole line will be highlighted again.
6. Press to exit the BOOST TIMER screen.

Economy Tariff Boosting
Boosting only when economy-rate electricity is available can be achieved in one of three ways:

1. By setting the boost timer to coincide with the economy tariff times. This option should be used only if the electricity meter is a dual-rate meter (modern meters usually are).
2. Boost only at set times AND if economy rate electricity is available.
3. Automatically boost whenever the economy tariff rate electricity is available, regardless of boost times*

• Options 2 and 3 are available only when using the eSense input. For option 1, the eSense Input in the Advanced menu should be set to Boost Timer Enable. With the Boost Timer Enable function set, the BOOST TIMER screen will include an extra column. The e can be toggled on/off. If e is present, the boost will activate only when the boost times are valid and the economy rate tariff is available. Alternatively the eSense input can be used to activate the boost whenever the economy tariff rate electricity is available, regardless of boost times (option 2). To do this, the eSense Input option in the Advanced menu should be set to Boost. When using this option, the Boost Timer is not needed.

Boost Time Conflicts
If one or more boost times conflict, the boost will follow the latest time or longest duration

Lock Function

zappi can be locked from unauthorised operation. The Lock Function requires a PIN number to be entered before the unit can be operated and/or a charge is allowed. The main display can also be hidden when zappi is locked.
The lock can be set to be active

• Only when the EV is plugged in
• Only when the EV is unplugged.
• All the time.

The settings for the Lock Function can be found in the Other Settings/Lock Function menu option.

preventing tampering with the charge session, or changing any settings
EV Unplugged| The Lock Function is active when the EV is disconnected, preventing unauthorised charging
If EV Plugged and EV Unplugged are both set, then the PIN lock is always active.

zappi is effectively locked against any unauthorised use and the PIN code will always be required to make any changes locally or to start a charge.

These are the recommended settings if zappi is mounted in an exposed / publicly accessible

location and you do not want anyone else to be able to use it.

Timeout| The time before the Lock Function automatically reactivates after being unlocked
Lock Code| This is the current lock code and is five digits from (1 to 4), it can be changed here Default code: 44444
Auto Hide| If set, this will hide the main display of the zappi to keep the power readings private
Charge:| Allow a charge session without the need to enter a pin-code. Useful to leave

zappi access free but with the settings protected.

Test| Tests the socket lock solenoid when the charging cable is not plugged in.
If zappi will be used to provide public access for EV charging, then it is recommended to use the following settings:

·         EV Plugged – On

·         EV Unplugged – On

·         Charge – On

·         Lock Code – changed to a private PIN number

Socket Lock
For untethered units only, the EV cable will be locked automatically when it is inserted into the zappi, even if it is not plugged into the EV. A small ‘lock’ icon will be seen on the right side of the zappi, in the centre of the screen. When the EV is disconnected, a press + of the button, will unlock the cable for a duration of 5 seconds, allowing the cable to be removed from zappi. After this time, the lock will be re-activated. If the ‘Lock Function’ (PIN lock) feature is enabled in the zappi, the cable will not be locked into the socket until the PIN is entered and EV charging starts. This means that if anyone plugs their cable into the zappi but they do not know the PIN they are able to remove their cable. In all cases the cable is unlocked if zappi detects a fault or the power supply to the zappi is switched off.

Configuration Settings

All settings are described in the Main Menu section; however, the more commonly altered settings are described in more detail below.

Time & Date
The date and time are used for the Boost Timer and the savings calculations and therefore should be set correctly. In the event of a power-cut, and providing the zappi has a connection to the internet the zappi will update the time and date automatically once the power is restored. Even if the zappi does not have an Internet connection its internal clock will continue keep track of the date / time for approx. 24 hours. Time is always in 24-hour format, but the date format can be changed. zappi will automatically adjust the clock for Daylight Savings Time (DST) as long as Auto DST is enabled, and the correct time zone is selected.

The following Time and Date settings are recommended:

• Timezone – set to correct timezone
• Auto DST – On
• Update from Cloud – On

Display & Sound
The Generation Icon on the zappi display can be changed to match your local system. Select between “Sun” (PV) and “Wind” on the Icons… submenu to change the icon If do not have any local generation then the icon can be turned off by changing the Monitoring… setting

RGB LED
zappi has a coloured LED light on the front which changes colour and flashes to provide a visible indication of the charge state. The brightness of the LED and the colours can be adjusted from the RGB LED menu.

Grid Limit
When the Grid Limit is set, zappi will automatically reduce the power going to the EV if it detects that too much power is being drawn from the grid.

CT Detect (“G100”)
“G100” is a UK standard which some distribution companies use when setting the requirements for the Grid Limit (or “load curtailment”) function in EV charging equipment. One requirement is that the equipment should detect if the grid CT is disconnected. When the CT Detect Protection setting is turned on (default) zappi will detect that the grid CT has become disconnected and will limit the output from the zappi to prevent the grid supply being overloaded. This setting applies to wired CT’s and is found on the Advanced – CT Config menu

Advanced Settings

The Advanced Settings menu is passcode protected. The default passcode is 0 0 0 0 although it can be changed with the Passcode menu option.

Supply Grid – Device Settings
Phase/Phase Rotation

Phase Return
When a single phase zappi is installed on a 230V delta connected supply, it is necessary to tell zappi which phase has been connected to the neutral terminal.

Single Phase zappi| The Phase setting is only used when installing a single phase zappi onto a 3-

phase supply.

It should be set to match the phase number that the zappi is wired to so that the power measurements are correct and that the zappi responds to the correct phase when using the harvi wireless sensor.

---|---
Three Phase zappi| The Phase Rotation setting is only used on three phase units and should correspond to the wiring to the input terminals. Only the following specific options are available:

·         1/2/3 (Phase 1 wired into “L1”, Phase 2 wired into “L2”, Phase 3 wired into “L3”)

·         2/3/1 (Phase 2 wired into “L1”, Phase 3 wired into “L2”, Phase 1 wired into “L3”)

·         3/1/2 (Phase 3 wired into “L1”, Phase 1 wired into “L2”, Phase 2 wired into

“L3”)

Note: In most installations the Phase Return setting should be left as “N” for Neutral zappi includes built in 6mA DC residual current protection (RDC-DD in accordance with EN 62955). An additional upstream Type A RCD or RCBO is required

Device Limit
Sets the maximum current that the zappi will draw (including when boosting and FAST mode). This is useful if the supply current is limited, for instance, if zappi is connected on a 16A circuit instead of a 32A.

Neutral Limit
In some countries the electricity distribution company limit the maximum current that can flow in the neutral conductor on a three phase supply (for example, the neutral current is limited to 20A in Germany). Use this setting if a neutral current limit is specified for your installation.

Earthing
Before starting a charge, zappi carries out a check to make sure that the protective earth conductor is still connected. This check only works in a TN or TT connected electricity supply. If you are on an IT supply or find that the protective earth check is too sensitive then change this setting to “IT”.

Supply Grid – Network Settings

Grid Limit/Load Curtailment
Sets the limit that can be drawn from the grid connection (i.e. the maximum import current or the main fuse rating).

Example: A property may have a grid supply limit of 65A. Several appliances are on so the property is consuming 12kW (52A). The user wants to charge in FAST mode. Without the Grid Limit set, the total consumption would exceed the allowed import current and trip the supply or blow a fuse. However, with a Grid Limit setting of 60A, zappi would temporarily limit the charging current to 8A (about 1.8kW) and the maximum allowed import current would not be exceeded.

• Note: When using a harvi to measure the grid supply, the highest value for the Grid Limit setting is 65 Amps. The maximum current limit when using a hardwired CT is 100A
• Note: For installation in the UK where the Distribution Network Operator accepts load curtailment instead of an upgrade to the supply, the Grid CT must be wired to the zappi and cannot be used with a harvi.

Battery
If the property has a static AC battery system installed, it is possible to get the zappi to work in harmony with the battery system, provided a CT has been installed to monitor the battery inverter.
The table below details the different settings for working with an AC coupled battery storage system:

the battery when using

surplus power from the solar or wind generation.

Avoid Charge| Effectively allows the zappi (or other linked myenergi devices) to take priority over

the battery when charging from solar or wind generation.

Avoid Both| Provides both of the above functions. This setting will normally provide the best compatibility
Limit to Gen| Will limit the output of the zappi (except when boosting), to prevent unwanted draining of an AC coupled battery system. This setting does not require a CT to monitor the battery but does need a CT to monitor the solar/wind generation.

Note : This setting is to support legacy installations – it is preferable to install a CT to

monitor the battery and use one of the settings below.

Net Phases
When enabled, all readings from 3-phase myenergi devices configured as 3-phase, will be netted. This means that surplus generation on ANY phase will be considered available for consumption on ANY other phase.

Note: With a three phase zappi, Net Phases should normally be turned on

Export Margin
This sets a minimum level of export power which is maintained when zappi is charging in ECO or ECO+ modes. Export Margin would normally be set to 0W (zero Watts) so that all available surplus will be used to charge the vehicle. In some cases, it may be desirable to always set a minimum export level set. An instance of this would be when using zappi with a hybrid PV/battery system.

CT Config
zappi measures current by using a number of Current Transformers (CTs). It is important that these are set up correctly so zappi knows the different power flows and can control the EV charge rate.
The 3 CT inputs should be configured to match the connected CT sensors. There are further settings for the internal CT which measures the current being drawn by the EV

Note: If you have CTs connected to a harvi then these CTs also need to be set up correctly. For a harvi, the CT settings are found through the Linked Devices menu rather than the CT Config menu.

Important: There must be only one Grid CT set (per phase) for the whole installation.

current of the zappi

CT Types

is the CT used to determine if surplus power is available.

There must only be one Grid CT set for each phase

Generation Only| Monitors Solar PV or Wind generation
Storage Only| Monitors a device that can ‘store’ energy (e.g. a third- party energy diverter) and enables the zappi to take priority over it. The power used by the third-party device is considered as surplus power unless the device is intentionally using grid power (i.e. it is boosting).

The CT should be installed on the “live” supply cable feeding the diverter, with the

arrow pointing away from it (i.e. towards the consumer unit / fuse board)

Gen & Battery| Monitors Solar PV or Wind generation that is combined with a DC-coupled battery
Monitor| Monitors any load, for example a washing machine or a lighting circuit. This setting can also be used to limit current drawn by myenergi devices on a particular circuit

which includes other loads.

AC Battery| Used to monitor an AC-coupled battery.

With this setting it is possible to manage the distribution of surplus energy between the battery and the zappi (and other myenergi devices).

The Battery setting in the Supply Grid menu is used to configure how the zappi will operate alongside the battery system. The CT should be installed on the “live” supply cable of the battery inverter/charger, with the arrow pointing away from it (i.e.

towards the consumer unit / fuse board).

CT Detect Protection
When using a wired CT for the Grid current reading, zappi can also monitor the CT to make sure that it is still connected. This is important when using the Grid Limit (or “Load Curtailment”) function in the zappi and is a required by some distribution companies. “G100” is a UK requirement which describes the technical requirements for export limiting schemes. It does not apply directly to “import limitation” or “load curtailment” schemes but the general requirements are referred to by UK Distribution Network Operators in this context.
Normally the CT Detect setting should be turned ON for wired Grid CTs

CT Groups
CTs can be put in groups so that their readings are netted (combined). For example, you might want to monitor two solar PV systems and see the total generation on the display. Use Group in the CT Config menu to set which group the CT should be in.

Note: Different CT Types cannot be in the same group, the group names make this clear. Only the first 4 groups can be used for current limiting, see Group Limits below.

Group Limits
Current limits can be set for certain CT Groups. When a Group Limit is set the myenergi devices in the group will limit the power they draw to keep within the set limit. Group limits should be set only on the master device. It is possible to use more than one group limit type (e.g. IL1 with MN1, so that there are two conditions for limiting). Some examples of how to set up the group limits are described in the table below.

Group Limit Example| Additional CT Installed| CT Config (all devices)
---|---|---
Limit current drawn by two zappi devices that are on the same 32A supply.| None; only the internal CTs are used.| CTINT

Type: Internal Group: IL1

Group Limit: 32A

Limit current drawn by a zappi device that is fed from a 32A supply which is also feeding another appliance (e.g. a tumble

dryer).

| One CT is clipped around Live of the 32A supply and wired to CT2 of the zappi.| CT2

Type: Monitor Group: MN1 Group Limit: 32A

Limit current drawn by two zappi devices that are in a garage which is fed from a 40A supply. A washing machine and dryer are also in the garage.| One CT is clipped around Live of the 40A supply to the garage and wired to CT2 of one of the zappi units.

Note : The other zappi does not

need to have a CT connected , but it will still need to have a CT input configured to be in the same Monitor group.

Preconditioning

Most EV’s provide a preconditioning function that can be used to prepare the vehicle for a journey – typically by warming/cooling the inside of the car, defrosting the windscreen and possibly warming the battery so that it is in the optimum state for driving the vehicle.
To avoid draining the battery to precondition the car, the zappi preconditioning mode can be set so that the power needed is provided from the electricity supply.

Note: This feature only works if zappi has detected “Charge Complete” i.e. the previous charge was stopped by the EV because the battery was full.
If this is not the case, then the only way to ensure that the battery is not drained during the EV preconditioning is to set a Scheduled Boost to coincide with time when the EV will be preconditioning.

Setting Preconditioning
The preconditioning mode can set to “On” or “Off”:

draw power zappi will revert to the mode set (ie ECO, ECO+ or FAST). If zappi is in ECO+ and there is not enough surplus generation then the charge will pause and zappi will

display “Waiting for surplus

On| When preconditioning is turned ON, the amount of energy (kWh) zappi should supply to warm up the battery / precondition the EV can also be set.

Once zappi detects “Charge Complete”, the next time the EV tries to draw power

zappi will start a Preconditioning Boost (to the kWh target set) and then revert to normal charging, in whatever mode it is set to.

Note: Some vehicles (for example the Tesla Model S) need a lot of power to warm a cold battery even for standard charging. If you try to charge one of these vehicles in ECO and ECO+ mode the EV may charge for a short period, stop because it does not have enough power to warm the battery and then immediately try to charge the EV again. We cannot guarantee that the Preconditioning Mode will cope with this situation but provided the EV draws a small amount of power the first time it tries to charge this should trigger the Preconditioning Mode, providing enough boost power to warm the EV’s battery and allow normal ECO/ECO+ charging to proceed.

eSense

The eSense input can be used for two function:

1. It can be configured to automatically activate a Boost during ECO or ECO+ charging, whenever economy tariff electricity is available. The eSense input must be wired to a circuit which is live or an external volt-free contact that closes during the economy tariff times for this to function.
2. It can be used to limit the zappy output or stop the charge – for instance, using an external contact from a smart meter or control box provided by the Distribution Company who may require the ability to control the power being used to charge an EV if their network is overloaded

the boost timer is set to

operate at that time.

Load Limit| If the eSense input is live, zappi will limit the charge rate. The default limit is

set to 7.2A but can be altered

Stop| If the eSense input is live, zappi will not charge, regardless of set charge mode

or a boost

myenergi app

The Myenergi app allows you to control and monitor your myenergi devices, in real-time, from anywhere in the world.

Setting Priorities
If you have multiple myenergi devices you can control how energy is distributed to each of them in your app and it couldn’t be simpler. Using your finger, simply select the device you want to move and drag it to the priority position you want it to take. The higher up towards the house icon, the higher the priority for surplus energy. The lower down and further away from the house icon the lesser the priority for surplus energy. If you have a myenergi eddi and/or zappi, regardless of the settings you have selected, libbi can only provide energy to the zappi and/or eddi if they are above them in priority. i.e. Anything below the house icon receives surplus energy in the order of priority, going downwards. Going upwards libbi will only provide energy to anything shown above it in priority.

Screen 1, above, shows eddi as the highest priority and libbi as the lowest priority. So, eddi will receive any surplus energy first, followed by zappi and lastly followed by libbi. As libbi is below both zappi and eddi, libbi can supply energy to them both (depending on the settings you have selected for your zappi and eddi devices). Screen 2, eddi has been dragged to the bottom which means eddi I now the lowest priority to receive surplus energy. libbi has been moved to the ‘same’ priority as zappi. Because they are the same priority they will both receive surplus energy equally but because libbi is above zappi, libbi cannot provide energy to zappi.

Priorities Explained

• For surplus generation energy, eddi is the highest priority, followed by the zappi, then followed by the libbi. This means eddi will receive any surplus energy first before it is offered to the zappi and lastly it will be given to the libbi, providing eddi and zappi aren’t in requirement of it. libbi is below both zappi and eddi meaning it can provide energy to both devices (depending on the preference you’ve selected either in your Myenergi app or on the eddi/Zappi device itself)

• For surplus generation energy, eddi and libbi are of equal highest priority so they will receive any surplus energy equally first. Surplus energy will lastly be offered to zappi which is lowest priority.
  Although eddi and Libbi are of equal priority, because the libbi is positioned below the eddi, libbi can provide energy to eddi. However, libbi cannot provide energy to zappi because zappi is positioned below libbi.

• For surplus generation energy, libbi and eddi are of equal highest priority so they will receive any surplus energy equally first. Surplus energy will lastly be offered to zappi which is lowest priority.
  Although libbi and eddi are of equal priority, because the eddi is positioned below the libbi, libbi cannot provide energy to eddi. libbi also cannot provide energy to zappi because zappi is positioned below libbi. However, libbi can still provide energy to the home.

• For surplus generation energy, libbi is the highest priority, followed by the eddi, then followed by the zappi. This means libbi will receive any surplus energy first before it is offered to the eddi and lastly it will be offered to the zappi, providing eddi and libbi aren’t in requirement of it. libbi is above both zappi and eddi meaning it cannot provide energy to either device. However, libbi can still provide energy to the home.

• This myenergi ecosystem consists of two libbis and an eddi. We will refer to the highest libbi as libbi 1 and the lowest libbi as libbi 2, for this example. For surplus generation energy, libbi 1 is the highest priority, followed by the eddi, then followed by libbi 2. This means libbi 1 will receive any surplus energy first before it is offered to the eddi and lastly it will be given to the libbi 2, providing eddi and Libbi 1 aren’t in requirement of it. libbi 1 is above eddi meaning it cannot provide energy to it but it can still provide energy to the home. libbi 2 is positioned below eddi meaning libbi 2 can provide energy to eddi as well as to the home.

Appendix A

Electric Vehicle (Smart Charge Points) Regulations 2021 As of 30th June 2022 Relevant to zappis INSTALLED from 30th June 2022

Electric Vehicles (Smart Charge Points) Regulations 2021

• From 30th June 2022, any EV charger installed in a private setting i.e. home or workplace NOT public, in England, Scotland and Wales has to meet the Electric Vehicles (Smart Charge Points) Regulations 2021.

Purpose of the Regulations
The new smart charging regulations are a huge, positive forward-step by the UK Government in preparing our homes and businesses for a smart, connected and democratized energy system. Essential tools in driving down emissions and a core reason why myenergi exists. The regulations are focused around when you are charging an EV. The aim of the regulations is to prevent everyone charging at the same time and putting too much demand on the grid.

What’s changed with zappi
New features have been added to zappi to ensure our products remain compliant with UK Regulations.

These include:

• Randomised Delay – At the start of a charge and end of a scheduled, Timed Boost there will be a delay of up to 10 minutes before your vehicle starts and stops charging. This could be a few seconds or it could be up to the full 10 minutes. This is necessary to ensure everyone does not overload the grid by starting to charge or ending a charge at the same time. The Randomised Delay can be overridden, if necessary.
• Smart Scheduling – To comply with the smart charging regulations your zappi will be set to charge in off-peak hours by default. This is between 00:00 – 08:00. You may change this schedule at any time if you would prefer to charge in peak hours or your electricity tariff off-peak hours differ from those set.
• Default to ECO+ mode – If Smart Regulations apply, zappi will default to ECO+ mode on first boot up.
• Charging logs – You will now be able to view a record of charging logs from the past 13 months. See Charge Logs section below for further information.

Randomised Delay: How it works
As mentioned above, Randomised Delay will put a completely random delay at the start of a charge and end of a scheduled, Timed Boost, for up to 10 minutes. This can be overridden by the customer in situations where they are in a hurry.

Delay Status
You will be able to see if your charger is in a state of delay at any time as it will be displayed on both the Zappi screen and in the myenergi app.

Overriding the delay
To override the delay simply press the ‘+’ button on the zappi or press the ‘charge now’ button displayed in the pop-up message within the myenergi app. If the delay is overridden your charge will start/stop immediately.

You cannot permanently override the delay function. If you wish to override the delay each time you charge, you will need to follow the above instruction to override on every applicable charging session.

Smart Scheduling: How it works
As summarised under section 1.2 your zappi will be set to charge in off-peak hours by default from initial start-up.

Off-peak hours
Off-peak hours are usually between 00:00 – 08:00, depending on your specific tariff, this is when your electricity will be at it’s cheapest.

Reason for Smart Scheduling
Encouraging you to charge in off-peak hours prevents overloading the grid in peak times.

Benefits of Smart Scheduling
Smart Scheduling will can help you spend less on your electricity. By charging in off-peak hours your electricity tariff may be cheaper.

Changing the set schedule
If the default schedule does not suit your requirements, or your electricity tariff’s off-peak hours differ from the schedule set, you can amend your schedule at any time from the zappi menu or within the myenergi app. To adjust your schedule in the app navigate to the ‘Set Boost Parameters’ option, select start time and set the number of hours you want your charger to boost for. To change the schedule on your zappi device navigate to ‘Charge Settings > Boost Timer’ and amend the schedule as desired. For further information see the Timed Boost section of the User Manual. Alternatively, the schedule may be deleted altogether, if required. To do this ensure all inputs are set to 00:00 for each day of the week.

Defaulting to ‘ECO+’ Mode
As mentioned in section 1.2 if your zappi meets the Smart Regulation parameters it will default to ECO+ mode upon first start-up. This can be changed to ECO+ or FAST mode at any time by the customer. See Charging Modes section of the User Manual for further information on modes.

Manual Boost
If you choose to remain in ECO+ mode you can still charge from the grid at any time by doing a Manual Boost. Refer to Manual Boost section of the User Manual for further information on this existing feature.

Charging Logs
Providing your zappi is internet connected and you have registered your device in myaccount you will be able to view a record of charge logs for the last 13 month period. This function will begin from 30th June 2022 so the earliest time you will see the whole 13 months will be from July 2023 or 13 months from when your device was connected to the internet. The charge logs will tell you when the charge started, when the session ended and the duration of each session. To view your logs log into your account at https://myaccount.myenergi.com/login Navigate to “My Energi Usage” in the left hand menu. The charge logs will be displayed like to example below .

Electric Vehicle (Smart Charge Points) Regulations 2021
As of 30th December 2022 Applies to all zappis Installed on or after 30th December 2022

Electric Vehicles (Smart Charge Points) Regulations 2021
In addition to the regulations explained in Appendix A, from 30th December 2022, any EV charger installed in a private setting i.e. home or workplace NOT public, in England, Scotland and Wales has to meet FURTHER conditions to the Electric Vehicles (Smart Charge Points) Regulations 2021.

Purpose of the Regulations
Every day cyber criminals make attempts to target individuals and organisations. With a cyber attack attempted every 39 seconds these regulations have been put in place to mitigate the risk of this and ensure your device and information is secure from increasingly sophisticated attacks.

What’s changed with zappi
The following features have been added to all zappis to comply with the Electric Vehicles (Smart Charge Points) Regulations 2021, Schedule 1, from 30th December 2022: Set-up Wizard – The set-up wizard at power up has been changed to ensure smoother initial set-up. This includes internet connection and firmware updates upon start up. Automatic Firmware Checking – zappi will regularly check for new software and will automatically display a message on your zappi screen to let you know in the myenergi app when updates are available. Tamper Detection – We have added built-in tamper detection to alert you if anyone has removed the front cover of your zappi. You will be alerted in the myenergi app when tamper activity is detected. Encryption – To protect your data from eavesdroppers zappi uses Advanced Encryption Standard (AES) to securely communicate throughout your home and across the internet.

Automatic Firmware Checking
Being on the latest firmware is one crucial way to prevent security breaches. To ensure you are always on the most up-to-date firmware, your zappi will regularly check for new software and you will be notified in your myenergi app when updates are available. You then have the option to select “Install now” or “later”

Tamper Detection
A tamper detection feature has been added to our zappi devices. This ensures that any time the cover is removed from your zappi you will be alerted that it has been tampered with.

AES Encryption
To protect your data from eavesdroppers zappi uses Advanced Encryption Standard (AES) to securely communicate throughout your home and across the internet. Linked devices will communicate via AES and communication between your devices and the internet will also be via AES. For customers with older myenergi devices that don’t have the compatibility to communicate in encryption there is a new device menu setting which allows you to turn off encryption. If encryption is turned off this will only turn off encrypted communication locally between devices. Communication externally across the internet will still use encryption.

Installer Requirements
It is the responsibility of the installer to ensure they are compliant with Electric Vehicles (Smart Charge Points) Regulations 2021. This includes, but is not limited to:

• Installing only compliant charge points in private installs from and including 30th December 2022.
• Answering the start-up wizard questions accurately to reflect actual install parameters.
• Having a Technical File and/or Declaration of Compliance available if requested by the customer (myenergi’s Technical File and Declaration of Compliance is available at: https://myenergi.com/guides/smart-charge-point-regulations-explained/
  The installer should ensure they are fully aware of and understand how the regulations affect them and what they are required to do to ensure they comply. These regulations should be monitored for any future updates.
