Multiples within a short time frame should force a complete shut down of the unit. Your 400 amp fuse on the 4-0 conductor blowing is another sign of this. It doesn't sound like you have a large draw though. Could your problems be with the wiring on the DC side? Some things to check . Is your wire run under 10 feet from the inverter to battery? Are all battery interconnections of the same 4-0 gauge. Are all connections of battery cable to battery/inverter terminals direct and of good contact?
Good luck.

I didn't think of that. The CA runs are short, the longest is about 3 feet, However I did use 2 gauge wire to connect the batteries together. It never occurred to me that it might cause problems. I will redo them and use
4-0 gauge wire this time.
Something else I meant to correct is all the multiple connections on one lug, such as at the disconnect switch.
I did order in 4 lug terminals and will install them when I redo the wiring.
Thanks and I will let you know how it comes out.
