here is a question, i have 2 victron multiplus inverters 3000/24/70 one from uk/jersey one from France, both have main voltage set at 230v from the factory.
i am using one temporarily to run a 3000w immersion heater till i pick up the new ashp, so at 230v i was getting overload alarm on the victron unless i boost fed it off my second battery bank and inverter, current draw was about 138a, so i was thinking 230v 13a near as dam it 3kva hence alarm, but at 220v it is 2.86kva, so i altered my voltage down and hey presto runs fine no more alarms and current draw at 115a.
just thought i would post in case anyone else is near the limit.
