Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a notice or ‘tip’ to guide you.
DANGER
Danger to life due to high voltages of the PV array, battery and electric shock. When exposed to sunlight, the PV array generates a dangerous DC voltage which will be present in the DC conductors and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal electric shocks. If you disconnect the DC connectors from the system under load, an electric arc may occur leading to electric shock and burns. Therefore, for safety reasons, safe isolation must be carried out with a properly calibrated voltage tester before an installer works on the equipment.

• The inverter can keep a life-threatening voltage even after disconnecting it from the DC and/or AC side
• Do not touch uninsulated cable ends
• Do not touch the DC conductors
• Do not open the inverter and battery
• Do not wipe the system with a wet cloth
• Have the system installed and commissioned by qualified personnel with the appropriate skills only

Prior to performing any work on the inverter or the battery pack, disconnect the inverter from all voltage sources, as described in this document.
The emergency power down procedure can be found in this document.
WARNING
Risk of chemical burns from electrolyte or toxic gases. During normal operation, no electrolyte shall leak from the battery pack and no toxic gases shall form. Despite careful construction, if the battery pack is damaged or a fault occurs, it is possible that electrolyte may be leaked or toxic gases formed.

• Do not touch the system with wet hands
• Do not put any heavy objects on top of the system
• Do not damage the system with sharp objects
• Do not operate the system in potentially explosive atmospheres or areas of high humidity
• If moisture has penetrated the system (e.g. due to a damaged enclosure), do not operate the system
• The libbi is not to be used by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they are supervised or have been given instruction concerning use of the device by a person responsible for their safety
• The transportation of libbi system must be arranged by the manufacturer or instructed personnel, including the Installer. These instructions shall be recorded and repeated
• In case of contact with electrolyte, rinse the affected areas immediately with water and consult a doctor without delay
• Avoid any maintenance to this equipment in adverse weather conditions, when located outdoors

Failure to comply with this EU Directive may result in a negative impact on the environment.
Operation after power failure
The battery system is part of the energy storage system which stores life- threatening high voltage current (even when the DC side is turned off). Touching the battery outlets is strictly prohibited. The inverter can keep a life-threatening voltage even after disconnecting it from the DC and /or AC side. Therefore, for safety reasons, it must be tested with a properly calibrated voltage tester before an installer works on the equipment.

Product Description

Product Introduction
Thank you for choosing libbi. These instructions will help you to familiarise yourself with the libbi energy storage system. These instructions will help you familiarize yourself with the product, and ensure you get the maximum benefit from your new eco-smart device.
libbi is an energy storage system that enables surplus energy produced by a PV array, or other renewable generation, to be stored for a home’s future use, instead of being exported back out to the grid. It can also be installed in homes where no generation is installed, to maximise the benefits of off-peak Time of Use Tariff prices.
libbi can be installed as a standalone product but will work in conjunction with other myenergi products: zappi, eddi, harvi, for a super ‘eco-smart’ home.
libbi is NOT compatible with zappi V1

Existing Users

Already have a myenergi device and registered account?

1. Your installer will pair your new device to your existing system.
2. You will see your new device is automatically added to your myenergi account and app.

myenergi app

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

Choose green or grid
You choose whether you want your libbi to charge using energy generated from your solar or wind generation (Green energy) or a mixture of generation and grid. There is a simple tick box in the myenergi app for you to set this option. You can change this at any time.
Green only charging
To use only the energy generated by your solar or wind generation, click the battery symbol on the home screen of your myenergi app, then untick the box labelled “Enable charging from the grid”. When unticked libbi will never pull any energy from the grid.
Green and Grid charging
If you would like to utilize a time of use tariff, where prices are typically cheaper overnight, simply click on the battery symbol on the home screen of the myenergi app, then tick the box labelled “Enable charging from the grid” under “Charging Preferences” libbi will always store your generated energy first before pulling anything from the grid. If you are on a dual rate tariff you will need to enter your tariff details into the myenergi app to enable charging from the grid. This way libbi knows when it is cheaper for you to use energy and it will only pull from the grid at these cheapest times.
Grid only charging
For customers with no solar or wind generation, you can still have a myenergi libbi. If no generation is present at the property, the box labelled “Enable charging from the grid” will need to be ticked, as the grid will be the only source of energy for your libbi.
You will need to input your electricity tariff details into the app before you can start to charge, so libbi knows when it is cheapest for you and will choose to take and store energy at these cheaper times of the day.

Input Electricity Tariff

If you have chosen to allow libbi to charge from the grid you must input your Electricity Tariff. This is so libbi knows when energy is cheapest for you and will only consume from the grid at those times.
You will be prompted to enter your tariff information in the app;

When the app detects a libbi – If you are an existing myenergi customer with existing products and are already registered with the app, you will receive a pop-up message prompting you to set your tariff information as soon as libbi is detected i.e. when the app notices a libbi has been paired with your existing devices.
If you tick the box to enable charging from grid – You have chosen to allow charging from the grid, you will receive a pop-up message prompting you to input your tariff details.

• Step 1: Select your energy supplier and tariff. The drop down tariff selection options are, Single Rate, Dual Rate or Dynamic Rate.

• Step 2: Once you have selected your energy supplier and tariff, click “Set my rates”

• Step 3: Assign rates to times of the day on the next screen. If you have multiple rates throughout the day, you can add more by clicking “Add price period”.
  

• Step 4: If you have different prices for different days of the week, select “Add tariff scheme” to input the full detailed breakdown of day, time and rate.

• Step 5: Once you have input your tariff details, select “Save” at the bottom of the screen.

You can amend and change your tariff details at any time by following the same instructions so, if you change supplier or tariff, just remember to hop on over to your app and update your energy tariff details.
If you selected a Single Rate Tariff at Step 2, it will not take you through to the next screen to enter your schedule of rates. As your rate is always the same, libbi does not need to know when it is ‘cheaper’ for you and will not charge from the grid.

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 is 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.
Priorities Explained
Example 1
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)
Example 2
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. libbi will not provide energy to devices on the same or lower priority than it.
Example 3
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. libbi will not provide energy to devices on the same or lower priority than it.
Example 4
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.
Example 5
This myenergi eco-system 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. libbi and zappi
For customers with a myenergi libbi and zappi, as well as being able to prioritise your devices, as spoken about in the previous section, you can also decide whether you want zappi to charge using your libbi or not.
Compatibility
libbi is not compatible with zappi V1 but is compatible with all later models.
When libbi is installed into an existing myenergi eco-system your installer must ensure all existing compatible devices are on the most current firmware in order for them to work with the libbi.
myenergi app (libbi and zappi)
In your myenergi app, there is the option to select whether or not you want zappi to consume from your libbi and it is a simple tick box.
Go to your app home screen and click the battery symbol. On the next page, scroll down to “Powered Devices”. If you would like libbi to provide energy to zappi then tick the box. If you would prefer libbi to never provide energy to zappi, leave this box unticked.
If you have more than one zappi, libbi will provide power equally to all devices, when plugged in at the same time, depending on your priority settings. zappi Device Settings
A new menu item has been added to our zappi devices which allows you to select whether you want zappi to drain libbi to charge your car or not. Select “YES” if you would like it to use energy stored in libbi or select “NO” if you do not want zappi to use energy from libbi.
This option can be found by in your zappi device, navigating to: “Other Settings” > “Advanced” > “Supply Grid” > “Device”
zappi – FAST Mode
If using zappi in FAST mode, zappi will not use energy from libbi. zappi will always charge from the grid or availble generation when in FAST Mode.
libbi and eddi
For customers with a myenergi libbi and eddi, as well as being able to prioritise your devices, as spoken about in the previous section, you can also decide whether you want eddi to use energy from your libbi or not.

Routine Maintenance & Cleaning

We recommend a routine observation of the libbi every 6 months. This should be carried out by a competent person and its main aim is to look for any signs of damage and abnormalities. This is a visual inspection only and should not entail removing the cable box cover or dismantling the libbi in any way.
