A customer has an Enphase system with 34 IQ8AC-microinverters, total inverter power 12.4 kW. Half of the panels face north-west, the other half south east. The highest recorded output of the pv system is 9.5 kW.
As he also runs a 5.5 kW CHP unit, I wonder if I satisfy or violate the factor 1.0 rule with a three phase MP II 5000 installation when the CHP and the complete pv array is connected to ac out 1
Id say the rule is violated.
First the factor 1 definition is using the rated power of the panels, not the rated power of the PV inverter. So the system very likely has more than 12.4kWp installed. You may even violate the rule just by the panels.
As for the CHP, first question should be if its supported by victron to connect a rotating generator on the ACout, even if its grid-following and can do a frequency-power-curve like an AC-PV. Im not sure about that. If it is, then the 5.5kW would add to the kWp of the panels, which already violates the rule if we assume 12.4kWp, since it comes out to a total of 17.9kW compared to the 15kVA of the proposed victron system.
However, one could argue that you can control the CHP to only start during night time while in island operation. But then you could also think about using it with a switchover (or using Quattros) on the ACin like any other generator.
