exactly budm!

OP needs a SERIOUS source of nominal 12VDC to even approach this unit's rating

I suspect if he did build a huge battery bank to run the thing for any length of time he would also have to address supplemental cooling for the inverter as it is clearly only intended to run for a few minutes with the original battery.

I think that 80+ Ah battery would be enough for that…those have strong screw terminals, they can handle 200 A no problem…

Very interesting observations, thank you very much!
Guess it's running normally and I'll just have to find other backup solutions for the furnace & water pump.
Thanks again!

80Ah battery will work for at least quarter hour at 200 A.

Looking at those RED and BLACK wires from the batteries, they sure look under rated.

This isn't proper wiring between the battery and the inverter to start with. That's not going to work for too long and not working good at all under heavy loads. Fix that cabling. You really want to put reliable 200A through that?
