Amperfied Wallbox Energy Control

← Chargers

Please read the wiring and configuration manual carefully. All boxes must be configured for external control in follower mode (DIP S5/4 OFF). Each box needs an individual Modbus ID (DIP S4). Ensure correct RS485 cabling including bus termination (DIP S6/2).

Supported features

mA regulation: Finer charging current regulation (mA instead of A) for better solar surplus use.
Built-in meter: Support for an integrated meter.
Dimmable: Power consumption can be reduced (e.g. §14a EnWG). See External Control.
