There is therefore an incentive for these customers to improve the power factor of their loads and reduce the amount of reactive power they draw from the grid. Most grid connected PV inverters are only set up to inject power at unity power factor, meaning they only produce active power.
Most grid connected PV inverters are only set up to inject power at unity power factor, meaning they only produce active power. In efect this reduces the power factor, as the grid is then supplying less active power, but the same amount of reactive power. Consider the situation in Figure 5.
Figure 7 (following page) shows the factory with the inverter set to a power factor of 0.95 - leading. The PV system is now producing 57kW of active power and 18.7kVAr of reactive power, reducing the amount of both active and reactive power from the grid.
As the level of Grid-Connected PV penetration continues to rise, the importance of power factor and power factor correction is going to become increasingly relevant both from the perspective of the grid and the customer.
