I used a Tripplite PV1250 which is an honest 1250W continuous with a surge capacity of 2500W for an hr and 3,000W surge for 10 minutes. Yeah, it will cost about $290 but it WILL power your fridge and not break a sweat.
PV1250 also has a power save feature which turns the inverter output on when the t stat turns on the compressor and turns the invert off when the t stat is satisfied.. Saves a lot of battery capacity.. I have mine set that the fridge light bulb will trip the inverter on when the door is opened.. Newer fridges are now using LEDs so it might be difficult to get the inverter to see the fridge lights.
I have the Tripplite RV750ULHW. The only things it runs right now is the home theater equipment and a plug in front of the passenger seat. Abouut 1 eveery 3 years we carry a 5cuft B&D chest freezer. It's surge Amps are 12 amps on the data plate.
I was looking at the RV1250ULHW or the RV1512UL. I have queried Don Boyd, lead tech at Tiffin, and he has said the 1250 will work but I need to check the wiring to see if the 1512 will work. For a 2000, I will have to have some wiring changed.
I have 2 T105 and looking to go to 4 or maybe 2 12V AGM.
Your current RV750 might be a bit on the light side but might work since Tripplites do tend to have a decent surge capacity and the RV750 has 1500W (12.5A at 120V) for ten seconds.
You could look at the RV1012 which would be 1000W continuous with 2000W surge (16.6A at 120V)for ten seconds if you didn't want to spend any more money.
Or, by the PV1250 and use as a dedicated fridge inverter (PV1250 does not have built in charger or ATS like the RV versions).
You would need to verify the wire ga, going up in inverter size most likely the wiring will be a bit light and running new wire to the existing inverter/charger might be an issue.
Upsizing the RV version also will upsize the charging portion of the unit (45A charging for RV750 and 55A charging for the RV1012).
