Inverter on or off?

Yeah, you want to make sure there is a problem, before you go looking for a cure!
I'm just thinking, your coach may have been built shortly after mine, so, if they screwed the wiring up on mine ...........

It is this weekends project, checking out the AGM. It is supposed to start, set up to do so, but it obviously didn't. I will bump up the starting voltage until it starts, or maybe I will need to unplug and drain the batteries down a bit also.

I have an older 1999 Windsor and the Refrigerator is on the inverter bus. If you run the fridge at about 3 amps AC that converts to about 30 amps DC. When I am dry camping I make sure the frodge is switched to LP.

The AGS takes some research to understand. Well at least it did for me. I had similar problems. You need to make sure it is “enabled” on the remote panel. Plus you need to check the settings on the control module in your basement, which should be adjacent to your inverter, settings such as Quiet Time, Volts Start, Run Time, etc.

Also, make sure your settings on the remote are correct. Such as, 80% Charge Rate. Flooded batteries setting and the correct amp hours for your battery bank.

You need to read the Magnum operators manual closely. Again, I was slow picking it up. You may not be.

Mine runs well now. I recently did several nights in a row Wallydocking without issues. Ran genset at night before bed and had 12.3 reading in the morning. I have four new GC flooded 400 amp hour batteries. I ran my AH but only the bedroom zone during the night, and I shut off my residential fridge prior to going to bed. DW even had the bedroom tv on much of the night.

.....I keep my inverter on, unless the coach is in storage.

I looked around and did a few things last weekend then quit. I was just sick of the 40* weather and pouring rain. The manual tells me to make all settings on the remote panel for the AGS which is in the front electrical bay, of course there is the panel in the hallway also.

I will get to it one of these days, and I appreciate all the help and suggestions.

I was told 80% charge rate was too high for 4 GC2 batteries, with a 100A charger. I have reduced mine to 50%.

If memory serves, my Monaco owner's manual recommends 80% Charge Rate for flooded batteries. It seems to work fine for mine. I initially increased it to 100% before understanding the consequences and this caused an Over Temp shutdown for a minute or so. Temps at the inverter get extremely hot...something like 214 degrees Celsius.

The fans in my inverter do not work. I plan to replace them, but in the interim I placed a small fan in the inverter bay pointed at it. So far this has prevented an Over Temp shutdown.

On ours, without gen/shore power, with the inverter ON, and the Hydrohot electric water heater ON, it's quite a draw.

Also you need to be sure at what fuel level your generator shuts down. My owners manual says at approximately 1/4 tank. But I’ve found that it actually shuts down at about 1/2 tank....
