I would like to use 3 phase multiplus 2 10kVA; and just connect L1 to house and L1, L2 and L3 to car charger. In case of load in the house approx 5-6kw and and I want to charge my car with 20kw 3 phase there will be some sort of over load on L1, does this set up have any kind of load preventing system or in case of one phase is over loaded other L2 and L3 will be limited such case? Thanks I am beginner with Cerbo GX and smart shunt with Chinese inverter and want to convert everything into Victron. Have 40kw lifepo4 battery bank and 20kw solar setup. Assume in case of this question solar and battery is providing enough energy. Thanks in advance.
Are you offgrid or on grid? Wi you have temperature controlled environment?
I would use larger inverter.
