Hello everyone. I have a 2016 Fourwinds 31W with a residential fridge. We enjoy boondocking but the inverter keeps beeping and displays an E02 Error.
The factory unit was replaced in 2019 and technician said it was fried. Now the replacement stopped working, beeping and again displays the same error.
The fridge works fine while connected to 30 amp shore power. Also this new inverter has a GFI outlet that works ONLY while on shore power. All batteries are new.
Any advise?

Regarding the GFI outlet…
- Thor (and others) with small inverters like yours normally power the non-GFI outlets. Fridge, TV, & outlets away from water

That’s how most all are set-up.

Regarding your inverter failure, seems strange that it’s got the same error message 2 years apart

E02 is the low voltage alarm (below 10.5 volts). First, reset the inverter by turning off the 120 volt CB under the bed that feeds the inverter. Second, go to the battery compartment for the house batteries and look for a 200 to 250 amp, 12 volt circuit breaker and trip it. Do not mess with the 100 amp breaker, as it is for the generator or the 50 amp beaker, as it is for the latching relay. After about a minute reset both CBs and hopefully you have a working inverter again. If the inverter still shows E02, your inverter is not seeing battery voltage and it time to use a voltmeter to find out why.
