Description of the product

The Smart/Solar Charger is a Mode 3 charger for charging electrical vehicles (EV) that complies with the IEC61851 standard.

The Smart/Solar Charger is equipped with several features to optimise power consumption and charging performance.

Dynamic Load Balancing The product uses a Sensorbox with current transformer(s) to measure the live power consumption of the power grid per phase and uses that information to manage the power output to your EV. When more electrical appliances are used, the power output to the EV is reduced to avoid overloading the power grid. The Sensorbox uses up to three CT clamps, one for each phase of the main grid, to measure the current flow of the main grid. The Sensorbox is also compatible with solar panel installations and can measure the direction of the current.

Power Sharing If you have purchased more than one charger, you can interconnect the chargers with a data cable and use the integrated Power Sharing feature to equally distribute the available power across the chargers points using the data from the Sensorbox. One charger is connected to the Sensorbox with a data cable. This charger acts as the Main Controller (MAIN), and manages the power for up to three Sub Chargers (SUB1, SUB2 and SUB3). It is also possible to use Power Sharing without the Sensorbox. It will function without Dynamic Load Balancing, the chargers must be connected to each other with a data cable and set in Basic mode.
Note: PureSolar mode is not compatible with Power Sharing.

Over the air update Over the air update (OTA) is possible, your charger can receive the available updates over the internet.

Multiple users and multiple cars Different users and multiple cars can be added to view the charging sessions of each individual online. A maximum of five users or cars can be created.

Ratio EV Charging App The charger can be controlled with the Ratio EV Charging App. The App is available in the Google Play Store and Apple store, or check our website. For more information, go to chapter 6.2.

Charge modes The charger has four available charge modes:

Basic

The charger charges the EV using a set maximum power in Amps (Maximum charging current). – no Load Balancing.

Smart

The charger only charges the EV when the available power is above the minimum set power in Amps (Minimum charging current) and below the maximum power that is still available on the main grid. *

SmartSolar

The charger only charges the EV when the available power is above the minimum set power in Amps (SmartSolar minimal charging current) and below the maximum power that is still available on the main grid. *
If the charger is charging the EV and there is still net power generation, the charger uses this surplus of energy to charge the car in addition to the minimum set power.

PureSolar

The charger only charges the EV when there is a net power generation (e.g. from solar panels), that is above the minimum set power in Amps (Puresolar minimal charging current). *

• Charging at a maximum current while protecting the building from overcurrent loading with Dynamic Load Balancing. While charging at home or an office building the charging current adapts to the maximum allowed consumption in the building.

Note: PureSolar mode is not compatible with Power Sharing. If you set the charge mode to PureSolar, Power Sharing will be disabled.

6.6. Testing solar charging functionality
It is important for the correct functioning of the charger to check if the Sensorbox is connected properly. 1. Temporarily switch off the solar panel installation. 2. Check if the LED on the Sensorbox periodically blinks red three times. 3. In the App, go to the Advanced settings and select Actual current. 4. Check the values for L1, L2, and L3. The measurements should only show positive values. 5. If any of these values is negative, reverse the 3.5 mm jacks of L2 and L3, and check if the
values are positive. 6. Switch the solar panel installation back on.
On the Sensorbox, the LEDs of the phase(s) on which the solar panel installation is connected should start blinking green when there is power fed back to the grid. 7. Check if the Actual current screen in the App shows negative power values when power is
fed back into the grid by the solar panel installation.
Note: If no power is currently fed back into the grid by the solar panel installation, perform this test procedure again when there is power fed back to the grid.
6.7. Updating the charger
Ratio recommends to always install available firmware updates. Firmware updates keep the data security of the charger up-to-date and occasionally add new features.
Updates are performed sequentially. This allows the system to offer multiple updates in succession. Always install all updates to ensure you are using the latest version. Read the release notes on the Ratio website or in the AppStores to learn about new features and improvements to the system.
Whenever a firmware update is available, the update icon is shown next to the charger in the My Chargers screen. 1. Tap the button for the charger to install the update. 2. Tap Install now to install the update or tap Install later to delay the update so you can
immediately charge your EV. The update announcement reappears the next time you access the My Chargers screen.
Note: make sure that the charger stays powered and connected to the internet during the update. Power/network outages can cause the update to fail. The Ratio EV Charging App does not have to remain opened during the update.

· Check the charger, charge cable and connector for any visible damage. · Make sure the power LED on the charger is on. · Make sure that the charge cable is properly inserted and locked into your EV. If you cannot find the reason why your charger is not working properly, please contact your local reseller or Ratio Electric B.V.
Points of attention if the App shows incorrect values while the charger is in Smart, SmartSolar or PureSolar mode:
· Make sure the arrows on the current transformers point towards the entry point of the main power grid.
· Make sure the current transformers L1, L2 and L3 are connected according to the phase sequence (Sine).
· If the charger indicates deviating values, it can help to switch the CT terminals on L2 and L3 on the Sensorbox.
· The mains input cable of the Sensorbox must be plugged into a power socket connected to the same phase as L1 of the charger.
Note: the Sensorbox 230VAC connection is phase (L) and neutral (N) sensitive.
· The Sensorbox flashes red if no solar energy is being generated (3x red). For example, if solar energy is generated and energy is fed back to grid on phase 1, the LED will flash 1x green and 2x red in succession.
