Greetings, I’m trying to repair a friends solar backup system. I think I need 10 modules if there are any available.
I have 16 modules of unknown status. All I know is, after cleaning them up and testing them individually hooking them up to a single battery (3.2V) I have 6 that initially flash a green and blue LED, then occasionally flash the blue LED (I’m assuming these are good). I have 4 that will only initially flash the green LED (probably bad) and I have 5 that won’t light up any LEDs (Definitely bad). These modules were in sad shape before cleaning. I have not hooked them up to a controller board, nor do I know how to at the moment. I’m just trying to get all the pieces in working order and I’ll figure the rest out later.
Cheers!
Rick
