OK Thanks Dan!!!
Do I just hold the switch to turn it off? Also will the batteries (I have two) if fully charged run the fridge for about 18-24 hours?
Thanks again
My understanding is that the remote switch operates the same as the local switch on the inverter. Press ON. Press OFF. I think the switches operate after about 1 second.
Once cool, with food in the refrigerator, on an overnight stop you might get 12-18 hours from the batteries and still have enough power to operate slideouts and landing gear.
But if you're starting up the fridge before a trip, it's going to run the compressor quite a bit more to cool down to operating temperature, so they'll be a greater demand on the batteries in that scenario. If there's any way to plug into shore power before the trip, that's the way to go.
You should be aware that if the trailer's umbilical cord is plugged into the truck, as the trailer batteries run down, you may also suck power out of the truck batteries. Some trucks pass power only with ignition on, others pass power with ignition off. The point being that it's probably a good idea to leave the cable disconnected on overnight stops so you can start the truck in the morning.
