The “grid code” settings affect the inverter only when exporting power into the grid.

The Quattro synchronizes to the grid VOLTAGE and it injects a CURRENT that may be in phase (PF=1) or slightly out of phase (PF < 1) compared to the grid voltage waveform.

The “grid code” settings do not affect the PF when charging the battery from the grid or generator.

The “grid code” settings do not affect the PF when running off-grid. The PF is set by the load connected to the inverter output and it can supply any load with any PF as long as the apparent power is less than 10 kVA and, at the same time, the active power is less than 8 kW.

Greetings. I hope this explanation helps.

I suggest understanding this issue is preferable using a vector diagram. The limiting true load limit is 8 kW (horizontal vector) & the limiting apparent power vector is 10kVA. This means that the optimum angle is 37 deg or 0.8, the stated inverter output pf (the resultant limiting reactive vector is therefore 6 kVAr).

Therefore, if your load pf <0.8 the reactive vector limits the continuous output, whereas if pf>0.8 the resistive load vector limits continuous output.
