Hi,
First time poster here. I built a solar and battery system in my travel trailer at the beginning of the year. I think I used good parts and it has worked really well until our last trip out. Total of 1100 watts of solar on the roof. Victron solar charge controller. Victron Shunt, Victron multiplus 3000 watt inverter and an EG4 12v 400ah battery.
The issue we had was that the battery would fault about once a day when the microwave was used. Microwave generally draws about 1500 watts. There were a few LED lights on the few times it happened and one time the heater blower was running. The heater generally draws about 75 watts. Total load wouldn't have been over 2000 watts which should be well under what the multiplus and battery can handle. The other weird thing is that the battery wouldn't come out of fault until I provided an external power source through the inverter from a generator.
I've tried to duplicate the issue to rule out some variables and nail down an issue but I can't re-create it. Happens when it wants to. I've gone through all the connections and wiring to look for a short.
Wondering if my BMS is bad or is going bad? Does that happen with these batteries much?
Thanks for any help guys,
