Hi
A while back I was given a small solar panel as a present from a family member and fellow caravaner.
I decided to use it to keep my leisure battery topped up whilst my van was in storage. There were no instructions in the box and the panel came with lead with a red and black croc clip on so I duly connected this to the corresponding terminals on my battery. I went back a few weeks later to find the battery flat and wouldn't hold a charge either so I changed it and didn't bother to use the panel since.
Turns out I think I should have used a regulator or controller as when I measured the output from the panel on a sunny day i was getting about 25V!! So I think I must have cooked it!
On further research I think I need a MPPT regulator .......... any recommendations please?
