Firmware update and wrong MPPT battery voltage selection

Over the past two months, I have commissioned several MPPTs. A recurrent problem following the firmware update is a low voltage system alarm. While checking the settings of the MPPT (Victron connect) I noticed that the MPPT failed to detect the right voltage level at startup and therefore leading to low voltage alarms.

I know how to fix the problem, but this situation is not ideal. Especially if I am giving support to a system installed in another country or that is connected via a can.bus (so far not supported for remote configurations with Victron Connect).

1. How could I verify and if necessary correct the system voltage remotely for a VE.Can connected MPPT device?

2. Did Victron notice this problem before? are you working to solve it?

Hi Michel, you can use Victron connect to access the settings of the MPPT, either locally or remote (if your system is connected to the internet and your MPPT is connected to a GX device via VE.direct cable). Under the battery settings, you will find the option to select the right voltage level for your system (battery voltage).

Best, Jose
