1. Features. AC Coupled PCS Inverters manufacturers tell you that the main function of PCS Inverters is that under grid-connected conditions, the energy storage system performs constant power or constant current control according to the microgrid monitoring instructions to charge or discharge the battery. AC Coupled PCS Inverters manufacturers tell you that PCS Inverters can smooth the output of fluctuating power sources such as wind power and solar energy at the same time; under microgrid conditions, the energy storage system acts as the main power supply to provide the voltage and frequency support (V/F control) of the microgrid, and the microgrid The load in the network works based on this voltage and frequency.
