Disconnect the battery (good for several months) or 100W solar panel and controller.

Ditto on Solar... determine how many Amps you typically use in a day... 100W Solar will generate peak of about 5.2A... so... rough estimate, if you burn through, say 25A/day, you might consider up to 500W solar.

I`ve got a 200W system in mind. basically just for if the power goes out in a campground (like it did for 5-6 hours on Labor Day weekend).

So if you are wanting to go solar, go with at least 200W, even 300 isnt that much more. but you will want more than one battery if you are going to boondock. otherwise for non use one battery is sufficient.

100W if solar.

100 watts would do just fine. If disconnecting be sure to fully charge battery before disconnect.

If I’m reading this right you will have it basically in storage. I have my original house battery disconnected from the coach. All I use it for is the tongue jack. I use a $15 solar charger from Academy and it keeps it nicely topped off. If you’re just looking for a maintainer to supply the phantom loads on your trailer, a little plastic 50 watt or so plastic panel will probably work. The beauty of these is they’re cheap, no mounting required, no fancy controllers and will keep your battery charged.
Im holding on for the you’re an idiot posts!
