One question, I have a new 100w solar panel fitted, which routes through a new MPPT controller, I am noticing that I am only getting 10 to 15w input and 0.6 to 1.1 amp output to the battery, the battery was on just over 12v when I took it out of storage it is a brand new 90ah varta LPD90 leisure battery, according to the instructions with the MPPT controller it states that it will keep charging up to 13.8 volts, however after being outside for 2 weeks I am still seeing just over 12v.
Is this because the panel is providing virtually no charge because it has been so dull? Or any other reason?
Hi Ceri
Have a read through THIS guys blog you may find it interesting, he does repeat himself a lot and he hates solar dealers but I think he knows his stuff according to him most controllers do not charge high enough for long enough to fully charge batteries, and the wiring needs to be beefed up, have a good read through you may find some answers. I take no credit for finding the web site as Broken Link Removed flagged it up originally:Blush:
