Hello all
I have VENUS OS 3.62 Installed on a Cerbo GX.
The system is 3-Phase (1x Quattro 15000/48 per phase)
There are 3 x SMA Sunny Boy 5.0 AV-41 inverters connected, 1 per phase on the AC-OUT.
1 x MPPT 450/200 on DC Side.
I have activated Dynamic Power Limiting of the PV Inverters turned on. All the MODBUS communication works fine and I have seen the system limit the SMA inverters power.
BUT, power limiting only happens when the ESS mode is Battery Life. When I set the ESS mode to “Keep Batteries Charged” and the batteries are full the Cerbo GX does not tell the inverters to limit power.
From the Cerbo GX console I can see the limit is 5000W for all 3 phases even though the inverters are exporting power.
AC/DC Feed-In is disabled
I momentarily turned off the Victron MPPT 450/200 and it seems then limiting works again and the Cerbo GX sends values below maximum to the SMA Inverters.
Help would be appreciated
