Solar Pure Mode (solar charging)

Solar charging is only possible in combination with a PV system and the KOSTAL Smart Energy Meter. The PV system supplies the power needed to charge the electric vehicle. With this function, the electric vehicle is only charged using the PV surplus.

For electric vehicles that are charged 1-phase, the charging power is between 1.4 and 3.7 kW. This means that charging is only started when at least 1.4 kW of surplus PV energy is available and is interrupted or terminated when this falls below 1.4 kW.

For electric vehicles that are charged 3-phase, the charging power is between 4.1 and 11 kW. This means that charging is only started when at least 4.1 kW of surplus PV energy is available and is interrupted or terminated when this falls below 4.1 kW.

NOTE

Info

Clouds/hysteresis for drawing power

If the necessary excess power is not available, charging is maintained for approx. 5 minutes at the minimum charging power to avoid unnecessary switching on and off. After the hysteresis time has elapsed, charging is interrupted and only resumed after a wait time of approx. 8 minutes.
