Hi ...I have 4 40w visionplus solar panels on my roof. A little while ago the battery was always flat having worked perfectly before. I get about 20.4v from the panels no load. With load, the terminals on the controller out give 11.2V From the controller the battery now does not charge but does with the engine going.
I assume my controller has gone as it is a recently new battery.
My question is the controller I have is 10A. Would it be ok to replace it with a 20A or 30A controller?
Many thanks in advance.
