I just bought a used Monaco 2009 Camelot. It has a residential fridge in it with a dedicated 1000 watt inverter and 4 tall 6v batteries. After a couple hours of running the inverter shuts down and the red fault light comes on (the house batteries are still charged). I hit the on button on the inverter and the fridge starts up again. Why does the inverter shut down after a couple hours?

It could be any number of things, such as the inverter overheating and the fan not working.

There might be a code list - depending on the manufacture.

Once shut off, the code may be removed from the computer's memory. I would contact the manufacture, and see if they will offer any support.

Have you actually confirmed that the batteries have a good charge?

Check the voltage of the batteries with a multimeter at the battery-terminals. The MH should not be connected to shore-power, or have the generator running for about 6 hours. Otherwise; place a load on them for a few minutes before checking.

What voltage did you get this way? A reading of 11.5 volts or less under load may set it off.

Your inverter indicates low voltage warning. Can be low batteries, a bad connection on battery-cables, at a solenoid, batteries, grounds, at refrigerator, or an inverter problem.

Is the fridge possibly going into an auto-defrost mode? It may be overloading the inverter. Just a thought...

Monaco NEVER installed low wattage Inverter's. Do you have 2 Inverters??? The smallest Monaco ever installed in a Camelot was a 2500 watt Inverter. I think the previous owner replaced the Inverter OR replaced the refer with the residential and added an extra Inverter? Which is NOT needed as the standard 2500 watt has MORE than ample power to run the refer. Give me your VIN or Monaco serial number and I can look up your build sheet to tell you what Inverter and Refer was factory installed. Doug

I'd check at what voltage your inverter is set to shut itself off at. If at 12.0 or above I'd change it to 11.8.

Hi Doug,
I have two inverters. a 2000 Watt Pure Sine Wave Inverter and a 1000 Watt Inverter with the Res. Fridge. I have the original window sticker that indicates that.

anything else using either inverter for power
like the water heater?
bay heaters to keep tanks from freezing?

1. Monaco only shows the 2000 watt Magnum Inverter for your year Camelot. We WERE a Monaco dealer until they went under and I had never seen 2 inverters in a Monaco with the residential refer.
2. Original Window Sticker???? Those can be dummied up by anyone with a Computer
3. That is why I asked for your VIN or the Monaco serial number as I can look up your specific unit and the OEM equipment.
4. It makes NO sense to install a 1000 watt Inverter AND a 2000 or higher Inverter when residential refers barely pull more than 500 watts. Doug

My vote is also for low voltage due to batteries. I recently helped somebody with this. A bad battery. Replaced just the one bad battery and all is well. It would take a while to show up, usually over night. battery failed load test.
