I have 3x 160w panels giving my 63v odd VOC and roughly 1amp when tested on multimeter.
(roughly 21v 1amp each panel)
The MPPT controller (Smart Solar 100/50) never shows more than 1v (Typically like 0.2v) and 0A.
I've checked polarity and there are no blown fuses and the batteries aren't fully charged.
So after trying everything, it turned out to be a fault with the controller.
hi, when all is pluged and your PV under the sun, what is the voltage on the screws of your input PV mppt??
1.05v max at the time of writing. It was a bit cloudy but I'd expect at least a few amps of charging.
If you unplug your MPPT, what is the string voltage and amps? If connected in series it should give you roughly 60v on an open circuit. Then check the amps. Check that your multimeter can withstand up to 10A.
