I have a BlueSolar PWM Light charge controller connected to a 60w solar panel and a 70ah battery. Everything was working fine during 3 months, then the controller just stopped working. It just went off and I can’t switch it on anymore, I removed all the wires and put them back again, I checked the battery and solar panel and they both work. But the controller doesn’t even recognize the battery anymore and all the light are off.
Any insights?
