What is this Solar Charge For?

It's so small I first thought it was an auxiliary charger for a cell phone. Maybe with an outlet on the dash.

But with the 'battery accepting charge' notice, maybe it is a charger for your Chassis battery...at least all those I'm familiar with charge the chassis batt because often, the manufacturer doesn't add an auxiliary charger for it. It's mostly charged by the alternator.

Mine covers nearly the entire top of the AC, and it's only 8 Watt. Useless.

Yes, but for engine or house battery?

it is a trickle charger

If parked in direct sunlight, the red light will come on to show it is charging the battery. Hmmm, my panel is larger than the one you show....I thought it charged the house batteries...not the engine battery....don't know, but the light doesn't come on anymore....

It is a maintainer charger for the Coach (Engine) batteries!

Mine had that also. It was a joke. Not big enough to do anything if it worked. Mine never did.

We do not have solar panels of right now, but my Brother does as he lives on a two story house boat. And that is one small panel, not sure of the charge that would supply.

It is a battery trickle charger and judging by its size is more marketing than useful . Very low input . Probably to the coach batteries .

I can't imagine that it has anything to do with the A/C. I would guess that the panel is just using the shroud as a mount. It is probably trickle charging your house batts.

It even indicates: "Light on only with battery is accepting charge."
