Hello, I have a 3 MULTIPLUS II 5k ESS system with 44kwh LFP battery with a 20kw Fronius ac coupling and an EV charger. When I start DESS and there is a negative price on DAM the system charge the battery until 100% SOC from solar and derate the Fronius to 30% to much the consumption loads. The problem is that although there is full sunny day and the Fronius can give about 12kw more, the EV chatger don’t start on auto mode. When I turn it to manual mode start charging and only then the Fronius increase it’s power to maximum!!
If anyone has meet the same problem i would appreciate proposals to make ev charging working on auto mode even on negative market prices!!!
