Yes, you can set the electricity mix by clicking on the tool icon at the top right in eco mode. There you will find the settings for smart charging. The “Optimization slider” allows you to select your individual electricity mix.
Why do you need this?
A vehicle requires a minimum charging current of 1.4kW (1-phase) or 4.1kW (3-phase). Small PV systems only reach these values at peak times. To take more of your PV energy with you, you can also “add” some grid current. This extends the charging time window.
Calculation example for 3-phase charging:
- At 100%, charging takes place exclusively from PV surplus and nothing is drawn from the grid.
- With a setting of 50%, charging is started when 700 watts (1-phase) or 2000 watts (3-phase) of surplus power is available.
- If the controller is set to 1%, charging starts as soon as there is a (small) PV surplus.
