What is PCS and Why is it important?
PCS is the core energy conversion device that connects energy storage batteries with the grid or load. Acting as the “commander” of the system, PCS ensures stable and efficient operation by:
DC/AC Conversion – charging batteries with converted DC power and discharging as AC to the grid or load.
Power Regulation – adjusting active and reactive power according to grid requirements.
System Protection – monitoring grid conditions and safeguarding the system during abnormalities.
Operation Control – supporting both on-grid and off-grid working modes.
How to choose the right PCS for different applications?
- Grid-Side & Renewable Energy (PV/Wind + Storage):
Typically for large-scale energy storage systems, PCS configuration is designed and recommended by professional design companies based on project requirements.
- User-Side & Microgrid Systems: PCS Power Selection:
PCS power ≥ peak load power. Battery Sizing: Battery capacity = PCS power × required backup time.
