Re: Stupid solar question
If you're under charging your batteries they will be damaged I'm just not sure of the timeline. I couldn't find any specs on the maximum input voltage to your charge controller but assuming the 18.9V of the solar array isn't to high you shouldn't damage anything else.
Any chance you can dock the boat and use an ac powered charger to top off your batteries as often as possible?
