i have a question on the Victron 1:1 rule again:

What is the exact Limit for AC-Power output of a PV-Inverter on a 3phase Multiplus II 48/5000 ESS system.

Reading through the Victron Docs, it seams, that "15kW" is the max. allowed PV-invertor output, if connected to AC-Out1 of all 3x Multis.

But my grid supplier requires me to feed in with some reactive power with factor 0,9 cos phi.

So i need grid settings with CosPhi 0,9.

In this case, the 15kVA PV-Inverter max. (apparent power) output is actually only 13,5kW active power with 1,5kW reactive power.

Is this already the max. allowed PV-Inverter power output?

Or is the stated limit meant as an "active power" limit?

If so, i could increase the PV-Inverter power to 16,67kVA -> which will provide 15kW active power with 1,67kW reactive power.

What do you think?

Is this OK? or would this exceed the 1:1 rule limit?
