Hi- fairly novice electrical guy here.
I have a working 100W solar panel setup to a 20Amp solar charge controller connected to a 12V deep cycle marine battery.
I bought this Massimo 100W solar panel/18v https://www.amazon.com/Massimo-Portable-Foldable-Charger-Powerstation/dp/B099Z53S2G
It only has barrel connector DC outputs/USB ports - so I bought a simple DC adapter to pigtail y cable to connect it in parallel to my solar controller.
Polarity was correct (pos to pos/neg to neg), but there was a spark, and I think my solar controller is toast - it won't detect voltage from either of the panels now (but it still shows the battery voltage).
My question- this SHOULD work, right? I can admit to sloppily holding the pigtails against the solar controller pole pieces and probably crossed them, causing the spark/short. Can these solar panels with built in DC output ports/USB be adapted to connect through a controller?
I have tested the panel output with a multimeter, the panels are both outputting as expected, but the solar charge controller detects nothing.
I will be buying another controller to test. I have also done troubleshooting including completely removing the charge controller, waiting overnight, connecting pieces one by one, etc.
