I have 2 BattleBorn 24v batteries, 300w solar, a BMV-712 and a victron 100/30 MPPT, all working perfectly until two weeks ago, when "possibly" the firmware upgrade altered something,
I had noticed that my SOC was low, usually 5-8% percent lower than 100%. MPPT showed fully charged, and when I unplugged and volt tested, all were at 100%. So the BMV was off.
Two days ago, I caught what was going on using the app (see screenshot). When an appliance , such as the roof vent started, or fridge compressor, the amps out shoot up WAY up. sometimes 50-80 amps, and sometimes as high as 280.
needless to say my system cant handle that, and its absurd to say the lease. for one thing, the roof fan is on a 15 amp fuse...pulled it when I saw it spike and as you would expect, the amps fell to 0.xx as they should be.
I have looked over every part of the system and have to conclude that I have a corrupt firmware, or of course I missed something.
anyone have any ideas?
