2. 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.
