Grid Feed-in max limit sometimes exceeded

Hi Guys,

running a 3-Phase Multiplus II in ESS with limited grid feed-in to 1500W and observe a lot more (up to 3000W) from time to time. This always happens when the load/critical load is particularly high. Can someone explain why this happens?

Thanks for help and ideas.

Unbalanced phase loading and three phase AC PV inverters do this.

I have seen that the AC PV does not like unbalanced phases.

The other question is do you have phase compensation on though?

Hi Alexandra,

thanks for your answer. Yes, phase compensation ist on, because it's highly recommended from Victron. I also notice unbalanced phase loads sometimes, but why should this result in such a difference as expected from the settings. For me it looks like the control algorithm is not working properly in this case.

Screenshot ( ESS limit = 1500W) attached:

Total of all phases or individual phase on the regulation? If you try the other does it help?
