Samsung residential fridge not running on battery

[bmortens]

Samsung residential fridge not running on battery power. We have 2022 Solitude with Samsung residential refrigerator RF18A5101SR. We just purchased the rig (used) and are trying to familiarize ourselves with the system(s) and appliances. The unit has both solar (with 2 marine batteries) and a generator. The fridge operates when the generator is running and/or while the unit is plugged in. However, when it should switch to battery power the fridge is not on. We checked the inverter (WF-5220) to see if there was a gfci that had tripped but do not see one on the inverter. The master shut offs are in the on position and the breakers are all on. We are stumped.

It’s working! We were having problems with the OneControl as well and due to our frustration we we did a reset to the OneControl, flipped breakers off, unplugged the rig and let everything set for a half hour. Plugged back in, turned breakers back on, turned inverter on, unplugged from shore power and the fridge is operating as it should on battery power. I can’t explain why, I just hope it continues to work.

If you were not plugged in, you need to have the inverter button turned on - it's in the upper right-hand bar cabinet, open the right door and look at the corner. You'll see a little button - press it and you should see a little green light signifying it's on.
Most folks seem to just keep it on, as it only is really "on" when you're not plugged into shore power.

Depends on the build. I don't have an inverter button. GFCI on my factory inverter which is a Magnum CSW2012 (it did pop once and took my Samsung and 120V offline). Took me awhile to find the darn thing.

Understand the math.

Your car batteries likely can supply 70-100 ah. Your fridge will likely consume that with other users in 24 hours at best. So, plan accordingly. No furnace.

If you use more than 50% of the battery capacity you will shorten their life.

The reason for the button is because the inverter consumes 1-2 ah of battery per hour on standby.

Also, inverters are typically about 80% efficient. So their use should be minimized as best you can.
