I have a 3 Ph 8 x 2 KVA Quattro + 24 Kwh BYD LVCS and EVCS .
The EVCS always shows the main house battery ( 24 KWh LVCS)- 100 %
The vehicles charging current power used is correctely displayed on EVCS ( matches VRM) and the EV .
EVCS and VRM running latest and the state of battery is same independt of EVCS state - charging or on standby
