How correct reactive power settings on your inverter can …
The power factor gives the ratio of real to apparent power. When power factor is equal to 0, the energy flow is entirely reactive and stored energy in the load returns to the source (i.e. generator) on each cycle. When the power factor is 1, all the energy supplied by the source is consumed by the load.
Power Factor Analysis of Grid-Connected Solar Inverter under …
The power factor (PF) plays a crucial role in determining the quality of energy produced by grid-connected photovoltaic (PV) systems. When irradiation levels are high, typically during peak sunlight hours, the PV panels generate more electricity. In this scenario, the PF tends to be higher because the real power output closely matches the …
Power Factor effects of an inverter on the Grid
Not necessarily; it just means that if the inverter supports non-unity power factor, its real maximum power output will decrease with decreasing power factor, as the VA limit will control. I.e. the limit is a maximum current, be that in phase with voltage or slightly out of phase with voltage.
Power Factor
Power Factor = cos θ Power Factor =cos 22° Power Factor = .92 --- this would be acceptable and may not attract chargers. However if this angle was "opened" due to the Reactive Power increase then: Angle θ = 40° Power Factor = cos θ Power Factor = cos 40° Power Factor = .76 --- this PF is now sub-par and would attract kVAR chargers.

What is Active Power setting on Growatt inverter
If the active power limit is 100% then the only time the inverter will output rated power is if the inverters power factor is 1 (Phi=0 degrees). The apparent power (volt*amps) and active power are equal. If the power factor of the inverter is anything other than 1 the active power is reduced. And thus the apparent power is also reduced.
