I have been having issues with my charge controller.
I have one solar panel (specs below) connected to the "Victron 100/20 SmartSolar MPPT" charge controller. When I tested the panel directly, the multimeter was reading 37.2v.
There are 2 x 12v leisure batteries (haven't been charged in a while) wired in parallel to the controller. The controller light flashes blue when the batteries are connected, but no change when the solar panel is connected.
Solar Panel specs:
Maximum power (pmax +10%,-0% - 245w
Short Circuit Current (Isc) - 5.86a
Open circuit voltage (Voc) - 53.0v
Maximum power current (Imp) -5.54a
Maximum power voltage (Vmp) -44.3v
Mamimum system voltage -1000v
Readings from charge controller:
I tested it again after a few hours and the Load was 12.45v.
Are these the reading I should be getting? Or is something in my set up wrong? I was told this controller would work in creating a 12v system (very important, don't want 24v).
"Nominal PV power, 12V - 290W":
Any help would be much appreciated.
