Sunsaver 20L blinking lights?
I have a Sunsaver 20 L for solar charge controller. The lights are blinking right to left - red, yellow, green. Also the other red light stays on, which should be green when everything is good.
I only have 12.2 volts showing, it should be higher, maybe 12.6 in full light. Batteries are only a year old, and have water topped of and terminal connections are clean, and new as of last December.
I can disconnect the 12 volt + from the solar array and reconnect and all lights are normal for a little, but next time I check is back to the blinking…
One panels has 16 volts (partly shady) and the other nearly zero, but connected together should both be the 16?
Climbing roof to see.
I can't find info what this sequence of lights means.
But the best I can tell I had wrong wiring. One solar panel had 12+ wired into the controller negative, but no paired negative wired in from that panel. I dont think this panel would matter since only half wired though. Fixed now.
