Is there such a thing as a solar charger that can charge two batteries, swap to a safe float charge when done yet sit inside the RV? Or at least a battery tender that will hold the charge? The batteries are 24s I believe. The idea is to keep the batteries at 100% while the RV sits in storage. My desire is to keep the electronics including panel(s) away from the weather and the curious.I've seen those large units but they seem to be for use at the sites. I inquired about solar chargers before but can't seem to pull up that thread.Thanks in advance for any help.Reg

Get a 100 or 120 watt solar panel with a 6 amp Morningstar Sunsaver controller and wiring. Mount panel on roof and forget about the batteries needing charging in storage. You can buy these components for about the same cost as a quality 15watt window maintainer that will barely do the job.

My concern is summer storms and the panels being unattended. If the panel(s) can withstand high winds, rain, hail and wind driven debris I'm sold.

if you are talking about the little 1.5 amp solar that harbor freight sell, save your money. they do not keep a battery charged. the propane and co2 detectors use up more than that panel can replace.,

A whole bunch of use have them and travel down the road hundreds of thousands of miles. Search on solar in the forum to see a whole bunch of examples

A solar panel is more durable than the roof on your house.

I'd go with the 100w+ model, too. Once you experience hands off battery charging, it's hard to go back.
