Want to add solar battery charger for storage use

[Dan_Diego]

I want to add solar battery maintainer to my attitude toy hauler. I intend to hang solar panel in a trailer window, running cables to the battery. The panel would only be connected when in storage. I am currently using two GC2 6 volt batteries connected in series. I would be grateful for any advice or hardware recommendations.

Yep...go big, as dedmiston says. 100-200watts will keep you happy when you're out there in Glamis or Borrego.

For those who check their batteries and can recharge in some way, yes, 2oldman. For the majority of RV owners you’d be lucky if they check anything at any time until it doesn’t work or blows out.

Hi Dan - Have you considered going full steam with your solar? We added 700W of panels to our roof a little over a year ago and it was one of the best upgrades we ever did. We hardly run our generator anymore.

If you plan to keep your hauler for a long time, it's a great investment and a HUGE convenience.

(4 x 6v batteries)

What is the wattage of the panel? Generally you're better off to disconnect a battery cable and check monthly.

I use a 30 watt panel and $22 weatherproof controller from WindyNation. The panel is roof mounted, however, on top of my RV cover.
