I have the VM-3P75CT installed in an ESS system using three Multiplus 48/3000. Previously I used the EM24. The reason was to speed up line regulation as advertised for the VM-3P75CT.
The manual says:
"High refresh rateCalculating the RMS power values for each phase, the energy meter transmits them at a high rate over VE.Can orEthernet, leading to more accurate measurements for power usage, grid-import and grid feed-in, for example, in an ESSsystem."
The VM-3P75CT sends data to the cerbo at remarkable speed, several values per second which looks good. It is connected via ethernet.
But if I look to the in/out sum power, then it jumps between e.g. -60 and +60 watts (when it should be 0) in the same way as with the EM24. I cannot see any improvement in regulation speed (in the VRM grid diagram).
My expectation was to see the curve more close to 0 compared to the EM24.
Is there anything that I have missed, any special setting or whatever?
