Before I switched to LED lights and before I got an Olympian Wave heater, I used around 90 AHr per day (24 hours) with lows in the 20's and highs of 35 to 45. This daily usage was without running the microwave.
The usage was divided fairly equally among:
- furnace at ~30 AHr/day
- lighting at ~30 Ahr/day
- trailer overhead (alarms, radio, fridge, water pump, fan) at ~ 30 AHr/day
After switching to LED's and the Wave heater, I am using ~ 45 AHr/day under similar conditions.
I suspect the reason it isn't less is because I still use the furnace for quick warm ups and I now run a couple fans to force warm air into enclosed areas that otherwise wouldn't get much heat. Probably use the lights more now too since it really doesn't matter much if I leave a few extra on.
Unless I am parked in the shade or it is overcast/snowing, my 300 watts of flat mounted solar easily recharge the four GC batteries each day (~45 degrees latitude in the winter).....unless my wife uses the microwave a lot :)
