All the voltages are stable and it's showing no AC draw. I'll try testing the battery bank voltage when on the inverter, I haven't tried that yet just made sure it was correct when on shore power.
If you are having flickering AC lights or on/off issues with AC appliances when on battery only, but not on shore power, then the problem lies in your inverter.

The first thing to check is the GROUND wire from the inverter; next, AC output cables from the inverter; make sure they are clean and tight. Third, check the battery connections, at the battery bank, at the big inline fuse and at the converter. Ffourth, check the connections where the AC cable from the inverter goes to your power center.

If the flickering is not caused by a bad connection somewhere, then what I imagine is happening is that your inverter is not making stable output AC voltage when drawing from the batteries. Google how to check receptacle voltage with a meter, but I think you'll find if connections are all good that replacing the inverter is the next step. Not hard to do but a mite expensive.
