I have a feeling that you do not have 110 volts from the inverter output when you are not connected to shore power.
When do house batteries need to be charged?
With a meter you should read a voltage at the positive terminals. They will read very low if no charging voltage is present. The house batteries (as well as chassis batteries) should charge when the engine is running, if not then you should find a fuse in a positive 12 volt feed between them and the alternator.

Is the APU charger connected to shore power?
The APU does NOT charge anything. It has no charger, but supplies 120volts to the RV so your Charger (power Converter) does charge. Yes, you are missing something. Connected to Shore Power, (with bad or NO batteries) you will still have 12 volt power in the RV.
Why does my generator not charge with shore power?
With HOT switching (Fire up generator while shore power present) when it switches There is arcing both at break and make, and if there are any motors running (Air Conditioner for example) the inductive “kick” can make that one BIG arc.. Plus strange things happen at Make that increase the size of the arc as well..
What happens when there is no shore power?
“The converter is what provides all this power when shore power is available. When no AC power is available, the converter just acts as a fuse panel for the DC circuits and the battery provides all the DC power at 12-13 volts to run everything. The converter’s power supply does nothing when there’s no AC power coming in.
Why do DC circuits still work when shore power is off?
So the same wires will provide power to the DC circuits when shore power is disconnected and receive power from the converter to charge the battery while connected to shore power. That also explains why the DC circuits still operate when the battery disconnect switch is set to off – the converter is powering the fuse panel for the DC circuits.
What happens to batteries when plugged in to shore power?
