My charge controller stopped working this morning. PV input on the cables is reading 30-34 but when I attach them they read at 2.3. Tried connecting multiple times, disconnecting all wires from charge controller. I took it off the wall and got down to a fresh section of wire and made sure they all connected well and that the screws were tight and the metal walls were pressed in. Same readings. I have no clue what it could be. Please help
Hi have a read of this.
PV voltage to MPPT I 30 drops when connected - DIY - Victron Community (victronenergy.com)
and this
150/35 MPPT Not Allowing Charge - DIY - Victron Community (victronenergy.com)
If no joy please post back. (Check the MC4 connectors especially if it’s been cold or wet recently)
Thank you so much!! It was the mc4s. A couple of them had rusted out. I swapped them out and one of the branch connectors for good measure and I’m up and running again. I live in Hawaii and we had some big storms recently.
