I'd ditch the Battle Born. They have reported defects. There are many quality LiFePO4's in the 300Ah range that can be found in the $300 to $400 range.

Regardless, running your AC for more than a few hours will take a lot of battery and solar to support it. It works, but don't expect a lot. We're not gas/propane generator fans, but that's the only way to use AC for extended periods while dry camping. 


edit to add that if your trailer is parked at home, you can use it as a power station during outages. You'll might need to upgrade the inverter, but that will cost you less than purchasing a power station and be better for dry camping. 

Another way to say it: the ONLY wire attached to the neg side of the battery should go directly to the neg terminal of the Smartshunt. I suspect you have some additional wires on that neg side of the shunt and or on the battery (from your solar controller). Move those to the system side of the shunt and you will see your state of change increase, not just decrease. You will need to recalibrate the state of charge by having the system auto sync or setting it to 100 when you know it's full. The shunt is not counting the current flow from the panel controller because it's not going through the shunt, but past it.  My unit was delivered with this erroneous set up.
