Inverter RS 48/6000 + 4xPylontech US2000C + CerboGX + MPPT 150/35 High Voltage Error

I use the above configuration and I have two issues:

1) I get Battery Monitor [512] - High voltage alarm: Alarm, the battery voltage is 52.41 V, SOC 100%

Do I need to adjust settings on the Inverter RS ?

I have activated DVCC and limited the charge current to 100A , all other options are disabled.


2) The MPPT 150/35 is connected to the Cerbo with VE.Direct and it shows up in the Device List but not on the dashboard of the VRM instance. Why ?

How much pv do you have installed have you follwed the 8x float rule for VOC?

Also Pylontec does do this if they are new for a bit then calm down a bit. I also think maybe you should have one more on the system

I have just 4 Panels @ roughly 40 V so way below 8x 50.

Is it a new install? If so, read the pylon setup guide - cell imbalances can cause this early on, best left on keep charged setting, if using ess.
