Solar Charger

[redthunder]

I am looking to get a solar battery charger to keep power up while boat sits on the trailer. Any recommendations on which one to buy? And are they any good?

I think there's answer if you're a little clearer on what you want to achieve.

Will an auto bilge pump run? Is there any other electrical drain? If the answer to either of these is yes, then solar charging will be of very limited benefit unless you're happy spending a lot.

On a good day, budget chargers can just about overcome the natural drain of a lead acid battery assuming there's no other source of drain like the pump. What they won't do, unless you're into serious spend and large surface areas, is provide a strong positive charge to a depleted battery.

Its on a trailer and would be just to keep the batteries up to starting. No bilge pump or anything else running.

I just bought one of these:-

10W SOLAR BATTERY SAVER + REGULATOR CABLE 12V PLUG & SOCKET 10 WATT | eBay

Not tried it yet,but it may be a bit OTT as the only drain is the tracker hence buying one with a regulator.

I've got one of them in the shed my father gave it to me when he got rid of his caravan he said it kept a 110amp battery charged no problem, i've not tried it yet to see if it works ,i might give it a go

Thats the one I have and it works fine keeps the battery up in relation to natural drain and helps if the is a demand from the pump. Better than nothing at all

Have you got the regulator as well? This one is for 2x110ah.

That'll do a job if there's only the milli-amp drain for the (Xenun?) tracker plus natural drainage.

Intersting claims in their eBay item description though...rated at 10W but produces up to 3 amps in the sales pitch later revised to 0.595amp (max) in the technical data...Hmmm.

There's others in eBay though that claim to work indoors too. Even better
