Hi Community !
I've a Problem with a MPPT 150/35. I got PV overvoltage Alarms.
As you see most of the Alarms last only 1s but some are longer. I've got 3 Panels in Series and 2 Strings in parallel (6 Panels in total). This worked für 3 years without a problem. The PV Voltage stays well within the allowed range.
I only get this alarm but the charger works well without any problems. Any idea why the charger is complaining about high voltage ?
Thanks a lot !

PS: my battery is nearly full at 11:00 .... so no current is going to the battery .... works a designed :D
