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.

For more information, go to chapter 6.2.

10 Ratio Smart/Solar Charger Manual

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.
