Post Subject: Electrics & Solar Charge

Hello, I am a bit of a boat novice, but have cut into the electrical circuit for the interior lights on the boat and installed a "cigarette lighter" type socket. If I plug a solar charger into this while the boat is moored, will it charge the leisure battery?

Before I answer your question please go onto tb-training.co.uk and read about cable sizing and fuse selection in the electrical notes you will find on that site. The answer depends upon the size of panel. If its a £20 job then it may overcome the batteries self discharge. If it is 40 watts plus then it will charge the batteries but may overcharge them unless you also have a controller. It will not charge the batteries if you turn the master switch off. Much also depends upon how you use the boat. A £20 panel will be no use for a livaboard but would help further battery deterioration if you leave your boat moored up while you are at home over the winter. Tony Brooks
