Hello, my charge controller (MPPT 150/45 - Tr) shows an internal error. Hence, my battery of my camper van will not be charged by the solar modules anymore. I tried to connect my phone with the charge controller, but since the dongle is hidden somewhere, I couldn't find or establish any connection. Therefore, I want to restart the charge controller manually. Does anybody know, how I can do that? (Or may know an alternativ solution for my problem?)
I would be thankful for any help or advice!
