Free QuoteThis is achieved by the battery inverter changing the AC frequency to signal the PV inverters to curtail their output power. The SMA default frequency shift power control, P (f), is set in the Grid Monitoring section in the EnnexOS or on the inverter.
In most regions, the standard inverter frequency for AC power systems is 50 or 60 Hz, representing the number of complete cycles per second. This inverter frequency is essential for the proper functioning of electrical devices and systems, as it dictates the speed at which motors rotate, lights flicker, and electronic components operate. 2.

When login successfully, click "More" > "Settings" > “System Parameters”. Enable “Frequency Shift Power Control”. For “Frequency Shift Test”, this is designed for customers to test PV inverter if it has the overfrequency derating function, which is not necessary for customer to set. Customers can set any frequency value more than 50Hz for test.
Several factors influence the inverter frequency, including the design of the power electronics, the configuration of the control circuitry, and the specifications of the utility grid. In grid-tied inverters, for instance, the inverter frequency is typically synchronized with the utility grid to ensure compatibility and seamless energy transfer.
From the perspective of control strategies, the participation of PV systems in primary frequency regulation can generally be categorized into two types: load reduction control and coordinated control with PV-energy storage systems.
