Parameters
8.2.11 RPO (Reactive Power outside of feed-in Operation)
KACO blueplanet 1000/875/750 TL3 M1 IS OD DEXo Model has a function to inject the reactive power only to
the grid at night and when PV power is low due to cloud. If the inverter generates the reactive power when PV
module don’t generates power, it can affect the grid stabilization.
