As I said in the original post, lights and pump is all that I will use the battery for.
My fridge does not have a propane option, so it only runs on shore power. Will use good old ice chest.
The furnace fan will run off of battery, but I don't plan on using it. Got some toasty warm sleeping bags and will use a small propane heater if needed while showering, etc.
The microwave isn't needed at all. The Keurig will be missed, but I have a coffee press or it might be worth firing up the generator for 90 seconds
Sounds like the 100 watt panel/controller will serve my needs.
