If you are generating energy from solar (or wind), you can choose if you want to charge your car with surplus energy rather than exporting it back to the grid. There are currently two modes for this in the Charging energy settings:
- Limited grid usage: will use energy from both the grid and solar/wind.
- Surplus only: will charge your car using only surplus energy.
Surplus charging is only available if Easee is listed as the site operator.
Choosing Limited grid usage, it will start charging the car with at least 6 A (or a selected value between 1 - 6) when you plug it in, regardless of the surplus amount. When there is available surplus energy, it will replace grid energy with the available amount. If the surplus amount exceeds 6 A, it will stop using grid energy. This option guarantees the car will charge at a minimum rate regardless of the solar/wind conditions.
Choosing Surplus only will only charge your car if the surplus energy exceeds 6 A (1,4 kW). Depending on the solar conditions, the car might not charge as much as necessary.
In both settings, the car will charge with as much surplus energy as possible. The car can charge with up to 32 A surplus energy if it is available.
When enabling surplus charging, it must have 10 minutes of stable exported energy before the charging can start.
If you have an active schedule, the surplus charging will only work inside that period. This might not be ideal unless your renewable energy comes from wind.
To enable surplus charging, navigate to the Equalizer card in the Easee app:
- Press the Surplus energy button.
- Select Limited grid usage to use grid energy when the generated solar/wind energy is less than 6 A.
- Select Surplus only to charge only when more than 6 A is supplied from surplus energy.
- Drag the popup card down to return to the Equalizer card.
- Easee app at least version 1.5.9.
- Equalizer firmware at least version 117.
- Easee must be set as the operator.
- Works with TN 1- and 3-phase, and IT 1-phase (not IT 3-phase).
- Equalizer device mode can not be Static.
- The Equalizer must report historical export data (indicating that energy has been exported to the grid sometime in the past).
