Can solar panels charge marine batteries?

Postby Warden » Sat May 12, 2018 4:47 pm

I'm having an issue where my boat is stored on a lot that doesn't have any AC outlets to connect the onboard battery regulator to charge the marine batteries. I can't park the boat at my house because there's no room.

I was wondering if anyone has rigged up a solar panel system to charge their batteries?
Solar panels run DC current, so I wasn't sure if a DC TO AC adapter would work if I connected the regulator to it. I also don't have a realistic idea of how long it'll take to charge up 3 x 130Ah deep cycles. I estimate it'll take 2 days under ideal conditions with a fairly large solar panel, but I have no clue if it'll even charge at all.

Any help is appreciated. Thanks

Hi Warden RV guys have been doing this for some time, I would check with your nearest RV store. I dont think you need a converter as the batteries are DC as well as the Solar Panels. You may want a conditioner with a limiter on it though. I havent done it myself but i would start with RV World

Thanks. I have talked to a couple RV places recently. Pretty helpful guys. The only issue I'm having now is charge rate vs cost.

I'm kinda shocked this isn't a more common thing with as much as fishermen travel.

You would need a pretty large area solar array to charge your batteries after a full day of fishing in order to get the current (amps) you need. You would also need a 12V solar panel for each battery or an electronic system to switch the current between batteries. Ive thought about using a solar array to maintenance or trickle charge my batteries while the boat is in storage though but you would still need a way to switch current between batteries (could be manual or electronic).

If you are a fisherman on the go and travel a lot I think a better set up is the electronic charger that connects to your tow vehicle and charges your boat batteries while you are travelling and also recharges your trolling batteries when you boat engine is running and you are out on the water. The one I have read about on this site is Stealth Charger (http://www.stealth1charging.com/). I dont have one but it sounds pretty good.

If you went that route you would be charging your trolling batteries while you are towing, even at night. Or you can plug in. And you are charging on the water when the big motor is running too.

Troy Lindner came out w/solar panels that are built into the boat. A couple years ago. Can't remember the name but a Google search will help YA
