Hi there,
I’m having an issue with my installation that I couldn’t find an answer for in the existing topics.
Setup:
-
Multiplus II 10 kVA
-
Victron current sensor on the grid
-
Cerbo GX
-
PV inverter: SolarEdge (AC-connected before the Multiplus AC In)
-
Communication between Cerbo GX and the inverter via SunSpec/Modbus (this part is now working after solving a previous issue).
Problem:
On the VRM portal, the grid data shows I’m exporting –559 W while the PV inverter is producing 619 W, which is incorrect I am not exporting.
On the dashboard, at almost the same moment, it shows exporting 6 W and the PV inverter at 617 W (the small difference comes from the 2-second delay between screenshots).
This discrepancy happens only when the PV system is generating power — at night, everything reads correctly.
(See the two attached screenshots for reference.)
