Sounds exactly the same as my Windsport.
TVs, outlet in console in front of passenger, one outlet in bed base (supposedly for CPap machine), outside fridge and power for media distribution box are the only ones powered through the inverter when running purely on battery power.
Doesn’t seem that you have a problem and it’s working as it should.
