I'm adding panels to my off-grid EasySolar system. I shut off the system, disconnected batteries and disconnected the panels. When I reconnected part of panels to test that they are OK CCGX display didn't show any charging. BlueSolar display shows only 0,15 volts. I checked the panels voltage which is healthy 107 V. I tried to reboot the system but with no success. The CCGX front page shows constant 20W in the PV box but no arrows showing any charging current.
What next? Can I have somehow destroyed the solar charger?
