I would like to confirm with you that the recently added grid feed-in limit function would be applicable to my system. I cannot test it myself as I have not purchased all the hardware.
I have 3 grid-connected SMA inverters totaling 14kW while my house installation can handle 14.5kW max (63A/230V circuit breaker). I am looking to connect MultiplusII 5kW in grid-parallel configuration with additional PV panels connected via both DC-coupling and AC-coupling (Fronius) to mainly server the critical loads.
I understand that in order to export energy from Victron to the grid in a controlable way I will need to install Energy meters on both the main line and on SMA inverters for Victron to know the current grid load and PV/SMA production.
Now, I noticed that during off-summer months my SMA inverters rarely exceed 10-12kW production. I would like to know if I can use Victron and its grid feed-in limit to set the maximum feed-in of both Victron and SMA at exactly 14kW ? (i.e. top-off SMA production with Victron power, if I understand correctly Victron cannot regulate SMA in a grid-parallel setup, correct?).
In above is correct, question #2: In reality, how strict is the realization of feed-in limit ? Is it possible that the system will exceed the 14kW limit for a brief moment and trip the main circuit breaker (14.5kW) ?
Thanks.
