Will add that applies to our original Heart series of inverter/chargers. When you have the remote panel (again typically in the sleeping room, the power switch on the inverter should be left in the off position, and the inverter controller by the remote controller in the bedroom. The default programming on the unit has the charger function always on whenever you are connected to shore power, or the generator is operating. This secular can be changed by dip switched in the back of the remote controller. If you do have the installation and operating manual for the Heart ?? inverter, and of the 120 volt wiring diagrams, go to this site’s library and download them. Must haves to fully understand the aspects of this system. I believe our Heart units were state of the art when our coaches were built.
Current like quality inverters/chargers are much approved with better efficiency, lower standby drain, and “true sine wave” AC power which is better for all inductive loads. On the flip side they are around $1,400 outright, thus the reason we are nursing our OEM units.v/r,

Joe,If your inverter is on your microwave oven will show the clock operating and you will have 120v power at most of your electrical outlets (not the refrigerator), and your inverter will be eating up your battery power.. I suspect your problem has nothing to do with the refrigerator, but is caused by leaving the inverter on while not connected tto external power or having some other source of recharging the batteries.. You have a remote panel mounted to the driver's side closet at the rear of the bedroom. That panel allows you to turn the inverter on/off. You also have a "camera" switch on the dash that turns he inverter on/off, and a switch physically on the inverter. For the inverter to be turned off, ALL THREE of these switches must be off. With all off, any one of them can turn it on. I suggest you make sure the switch on the inverter is always turned off so you can control it from inside the coach. Awfully inconvenient to have to go to your electric bay to turn it on or off, especially at night or in inclement weather, when you could have done so without going outside.
Your refrigerator constantly uses DC power to run the control board when he refrigerator is on, but it is not a big draw that would kill the batteries in a matter of overnight. The inverter, being left on is not providing any 120v power to the refrigerator, but consumes close to 200 watts of 120v in it's inefficiency, even if nothing is using 120v power from it.
