Dry Contacts Providing AC Output Frequency Switch Between 60Hz / 62.5Hz

The power output of the Grid Tie Inverter varies with the sensed frequency of the waveform provided by the battery-based inverter. SMA defines this as Frequency-Shift Power Control (FSPC), Schneider calls this Active Frequency Shift Power Curtailment (AFSPC) and SolarEdge presents this as Power Control Option → P(f). Currently, some of Sigineer Power’s US version […]
