Hello Victron community,
I have a problem with one of my MPPT150|35A. Eventough I disconnect the solar panels I still get an overvoltage error #33 (Error code: #33 - Input voltage too high).
My setup consists of a pylontech battery and five MPPT150|35A controlled and monitored by a Cerbo GX. Every MPPT150|35A is connected to 6 solar panels. Three in a row and two in parallel. The open circuit voltage of a single solar panel 41.14 V so 124.2 V is the max string voltage.
All MPPT150|35A work like a charm expect one MPPT. This MPPT drops the error #33 overvoltage. The max voltage in the history of the MPPT is 130V.
First thought was, that this solar panels have the longest distance to the MPPT with approx 30m and the inductivity might be a problem.. I tested other panels with shorter cables and got the same error. Today I disconnected the solar panels completely and still have the same problem.
What are your ideas?
Thank you very much!
