So yes to get started here I am new to solar but have on and off studied it over the years. I jumped in head first 6 months ago and love it. I have pretty well just been experimenting to see what works.
I managed to acquire some 12v marine batteries from salvage and revive them to a pretty even balance. I am currently using 12 marine batteries that were paralleled but now are run in a 24volt series. They are charged with 4 renogy 100 watt panels also series and 4 Photowatt 50w panels in series.
Question is that on my Renogy Rover 40a CC once the sun goes down…the charge will read out between a 25.1 and a 25.5. I would assume this means my batteries are maintaining a charge but that charge is on the very low end of a life cycle. Is this correct?
also yes I am upgrading to 6 volt batteries just searching out what is best for that type of battery yet cost effective.
