Hi BFL13,
I found the duty cycle was 2:3 on the Dometic fridge. So the panel would catch up during the 20 minutes per hour that the fridge is off.

Been meaning to test that fridge (Norcold 8cuft) on inverter anyway, so just did it as backyard test. Fridge off in trailer doors open. Unplugged shore power turned off converter, plugged trailer into inverter as when camping.
Turned fridge on doors closed 120v and Trimetric showed amps at about 24 amps due to fridge, with some 25. I would expect "amps creep" from inverter if left on.
My 230w panel on that set of batteries that inverter is on can do say 16 amps so I would be short maybe 8 amps for running the fridge when the fridge is doing an on cycle with full solar.
