Asymmetric DC Export

I saw the same today. Saw it already before occasinally. But today one Multi 5000 was at full load (~4kW) while the others just fed in a little…
Didn’t see your entry, thus I also created one:

3 phase ESS DC feed in not balanced

Hi all, From time to time I notice that the DC grid feed-in is not balanced between the three phases. Today it was like this that one Multiplus-II 5000 (phase 3) was working at full load (~ 4000W), so it was quite warm while the other two were only feeding in a little. I needed to deactivate the DC-coupled PV feed-in excess and activate it again to force the system to balance the PV power across all three phases. How should this work? Should it always distribute the DC PV power equally across …
