Solar to keep stored battery charged?

Kit should work well. Good value too.

Yes 100w with good sun should keep the fridge running on propane.

Only issue is 40' of wire might be short as that leaves 20' from panel to controller. If you need more ask for the length you need for a nominal cost increase. I assume roof mount and down around stuff can take more than it seems.

With sun and only fridge on gas + detector being used, as long as the gas holds out.

Would this be enough to keep the fridge running while not plugged in ? If so how long could it sustain the battery with the fridge on?

I have that Windy Nation kit. Installed it in the spring, and camped two separate weeks with no hookups. Never dropped below 12.5 v on the battery, and we didn't conserve electricity. But, we aren't huge electric users, either. Water pump, lights.

Not sure where you saw $180 for the kit, though. I paid $214, then saw it for $160 a couple months later, but that only lasted about a week.

I like the kit. Came with everything you need for what you are wanting to do. I did a no-screw mount on my trailer, so I got some aluminum bracing, and some 3m VHB tape. Still on, after 3000 miles of travel.

100w kit for $180 will work well and is a good value. Have a link?

Do you ever have a need for solar power when camped?

100 watts and no just to keep the battery topped off.

You can get a WindyNation 100 watt panel and 10 amp controller directly from WindyNation for $170. The controller will go on when batteries are 10.5 to 13.7 volts and will turn off when batteries exceed 13.7 volts. This will likely keep the house batteries "topped off" but will not charge discharged batteries. The 24 cell solar panel is not the greatest.

Nice price, do you have a link?

Cheep enough.
