So I’ve been having trouble keeping my battery charged in the winter here in Central BC (short days, low sun). In a thought that maybe it was my ‘salvaged’ gel battery from work that was the issue. I pulled the trigger on a Renogy Lithium heated battery, a new Wonderer controller, and BT monitor.
This afternoon after installing it, I see that I’m only getting about 4W out of my Renogy 100W flexible panel on the roof of the rig. So at that I’m only getting .4A of charging which is barely enough to make a dent.
Does anyone else have this similar setup? How is it performing? I wonder if I have a bum panel. The whole purpose of getting the heated battery was to help in perform in the cold. But it needs 4A charging in order to activate. I don’t see that happening the way things are right now. I need at least 54W coming out of that panel in order to get the required 4A at a 13.5V float voltage (+/- cable loss)
