Has anyone added a smaller inverter to their class A to run their residential refrigerator while boon docking? I know we an set our generator to come on when the batteries get low, but would prefer to use a smaller inverter while we're out exploring.Pointing to me a page or photos would be a great help. Thanks.

Just received a quote from Lazydays to install residential refrigerator and larger inverter (recommended by Forest River). They are going to start Monday. Forest River recommended 2000 watt oure sine wave 100 Amp chagrer, part #40E14212A for our Berkshire. Good luck

Creeper, The only thing you will gain is a very small amount of the quiescent load the current inverter presents. It is my personal opinion that the gain will be no advantage. You will save nothing when the reefer is running as inverters only pass what is needed and the internal power loss of virtually all inverters is about the same for a given load.Matt

I can not see any advantage in adding an additional inverter just for the fridge. The one you have should be just fine.

Going on 3 years, we had a Samsung 197 RR frig installed. My coach came with a 2000 MSW Xantrex inverters but we had a Magnum 2812 PSW inverter installed with a new controller at the same time and the frig has been on the inverter 100% of the time plus I don't have to reset the microwave. The only thing I do is turn off the ice maker going down the road. We can go about 10hrs boon docking before my batteries drop down to 12.2v then I start the gen set for about 2hrs, morning and night. JR

Thanks.Adding more batteries and/or solar cells is the answer and not a smaller inverter, unless it's so huge that the unit itself draws a lot of battery current at idle and without a load, but I find that extremely doubtful. However, even if your fridge should quit, it's going to be quite a while before the temp goes down to a dangerous level and as long as no one is opening the door.
