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.


Cheers!
Dan

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

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

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.

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.

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

Putting the panel in a window may reduce the power output a LOT.

Far better to permanently mount on the roof.

For 2 golf cart batteries I'd recommend 140 watts (or more).

But I say “go appropriate” based on an energy survey of what you use (amp hours) or what you would like to use. Throwing money (solar watts) at a problem (need more power) isn’t the answer.

Save your money, charge the batteries fully and disconnect the ground battery cable. Batteries will not lose their charge.
