Re: High Battery Reading 15.7

btw if indeed you have 15.7 volts at the battery with nothing connected...many things like small bulbs and the like or fuses might pop...so are you absolutely positive that the voltage is 15.7 with NOTHING connected to the battery, not even the battery switch, negatives etc...?

Re: High Battery Reading 15.7

Thanks for all the info.

It is a 12 volt, flooded deep cycle battery. From the posts, I see the problem.

I will replace the battery. So, for a Group 24, flooded, deep cycle battery using a 30 watt panel what would be the specifications for a pwm charge controller? Best brand of controller to buy?

Also, I am just wondering why this battery is reading 15.7 and did so all winter with no charging at all. I checked it with two voltmeters.

Re: High Battery Reading 15.7

a 10amp pmw will do you good...and allow for adding another panel at a later time...

Re: High Battery Reading 15.7

Best choice is a Genasun MPPT controller - the GV-4 if the 30 watt panel is all you will have or the GV10 if you plan to add another panel. They will give you the best charging from the panel at the proper voltage.
