Question: Truck Battery Bank for Shore Power
Based on some back-and-forth with my original post, I've redefined my problem. 1. Situation: I'm trying to use the battery bank on my truck for shore power for my travel trailer. I want to be able ...

Want does "works" mean? You are getting low voltage alarm and shut down with the 2000w but not with the 800w.
Are you trying the 2000w with a big load like the water heater on electric, but not when using the 800w? Does the 2000w "work" with the same load as the 800w?
If all it is that makes the 2000w not "work" is a big load, you can reduce the voltage drop so it stays above 11v under load, by using fatter wire between inverter and battery bank, balancing the bank better with no "downstream batteries", and making sure the batteries are well charged up (needs an hydrometer for that to be sure)
BTW that red plug above is not supposed to be used in the Code ISTR.
