Dock power

System
System Posts: 2,511 admin
I'm looking to have power on our boat dock, we used to have power but due to lake regulations we had to remove the line to the dock so I'm looking into now having solar power.

The dock is not used on a daily basis mostly just used on weekends during the summer with occasional use during the winter. use consist of running 2 or 3 30 watt lights for a couple hours one or two nights a week. also I would like to be able to run a battery charger for those couple times a year that the boat battery is dead.

I had considered using this solar panel http://www.solar-electric.com/kykc130wasop.html
with this controler http://www.solar-electric.com/modubachco25.html

I already have 2 29 series deep cycle batteries that i could use for the system that are only about 4 months old.

thanks for the help i look forward to going solar

    Welcome to the forum.

    The sizing of an off-grid system is dependent on loads. If you know your loads you can get a good idea of system size. For instance three 30 Watt lights is 90 Watts. For two hours it's 180 Watt hours. So that's something to go on. The other questions would be: can you use DC lights and eliminate the need for an inverter? What Voltage/current do you need for recharging your boat battery?

    It would seem logical to me to try and go all DC and a 12 Volt system. For the lights that would be only 15 Amp hours. Easily met. Recharging or boosting the boat battery wouldn't be difficult either.

    Lots of possibilities here. :D

    why not recharge the boat battery with the pvs so it won't die?
