The EVSE - the setting of the charging current
You can set the charging between the 6 Amp and more. Please note that the maximal charging power depends on the power rating of the electric car charger. Example: If you have a 3.3 kW on-board charger, the maximum power will be 3.3 KW (some 14 Amps) even if you set more.
