Well, the vendor initialy suggested 2000W, but found out 3000W costs about the same, so the 3000W. Refrigerator runs on DC only.
Didn't know when under 12.2vdc, it's hurting battery. Learn something new.
I don't believe my generator or AGS has any information about automatic start or stop conditions. Need to find out from the dealer or Thor. I also need to set up my AGS apps so I can see the status on my smart phone.
Thanks for the information.
Above I had typo of 12.vdc that should have read
my house batteries may be 12.7vdc and my AGS will turn on genny around 6:00PM and shut off at 8:00PM because of my quiet time settings.
You did good getting 3000w for same cost as 2000. I only have 1000. The 2000 unit unit of same mfg is plug and play; so if mine ever dies ( 5 years old now) I will buy the 2000 to replace.
My microwave is the only thing my 1000 will not run, an inconvenience maybe 4 times a year; so not a big deal for us to fire up the genny.
I guess my point was you said you left your awning light on overnight, and inverter eventually beeped at 10.8vdc, so I was just trying to rationalize what you may be running additionally to have 3000watt inverter? The Fridge is a given, but is it residential or propane absorption mode that was running overnight? It could be a lot of other stuff draining that battery if your Inverter was actually on ( the awning light may have been innocent culprit) i.e I bet your 3000 inverter with absolutely nothing connected to it will draw more against the house batteries than the awning light.
When you say my generator or AGS in context to automation... Think of it this way... There is no such thing as Generator or AGS as you state. They are two different things. Short internal self controls, No Generator has any user defined automation. From reading it is not clear if you have a AGS? If you have AGS you will have User Defined Settings somewhere. That is what a AGS is and what they do. i.e. my coach did NOT come with AGS. I bought the Onan EC-30 and had installed on my brand new coach. I use my AGS exclusively. Ironically, about the only time I manually turn my generator on/off is on the road at a gas stop and we want popcorn, or to heat something up. I fire it up manually, and I just remember to let it run for at least 10 minutes before I manually turn it off.
Because of my AGS, when no SP, my AGS will tell my genny to start when temperatures in the coach gets to hot ( I decide what temp is too hot) or when the battery gets too low ( I decide what is too low, for my AGMs I have selected at 12.5vdc) If my coach had the same unexpected draw as yours, then the genny would have started up automatically when batteries hit 12.5vdc, I would have known something was wrong i.e. bad batteries or something was left on to get fixed, but I would not have had dead battery. With that said, if I was at a campsite my AGS would have been in Quiet Mode so it would NOT have come on after 8:00 PM or before 7:00 AM (I defined those settings in my AGS); If I had SP at the campsite it would not matter, but most of the time when I am at a campsite, I do not have SP unless it is summer and hot. My fridge runs on propane at night with no SP.
Final helpful need to know. Flood lead acid batteries should not go below 50% State of charge. Per my Onan Owner Manual the 50% SOC for FLA = 12.2vdc and for AGM = 12.4vdc scales vary. I have AGMs. My setting is 12.5 vdc ( my choice). I would go nuts if my batteries were anything below 12.4dc. Yes they would still work, but I would be slowly destroying those expensive batteries, just like dealers do on the lots
