⚙How It Works
The high-voltage PCS pairs a 750 V+ battery cluster with the grid, running the bidirectional conversion at high DC voltage to keep current low and efficiency above 98 %. At the 50–500 kW scale the PCS-HV becomes the power-electronics heart of containerised and utility storage, providing fast charge/discharge, grid-forming black-start and full grid-code compliance for frequency and voltage support.
▦Structure & Composition
The PCS-HV uses a three-level NPC or SiC bridge for lower switching loss at high power, a high-DC input stage with pre-charge and insulation monitoring, an output filter and an integrated cooling system. Redundant auxiliary supplies and a serviceable rack layout support 24/7 operation, and dual communication paths (CAN + Ethernet/Modbus) tie it into the plant SCADA and EMS.

Applications
Selection Guide
- Containerised BESS, frequency regulation and utility storage of 50–500 kW per unit.
- Verify the DC voltage window against the battery cluster before sizing the PCS.
- Use grid-forming units for microgrids; grid-following units suffice for grid-tied peak shaving.
Frequently Asked Questions
What is the efficiency of the high-voltage PCS?
Peak efficiency exceeds 98 %, with three-level or SiC stages keeping switching loss low at high power.
Can one PCS run both grid-tied and off-grid?
Yes, it switches between grid-following and grid-forming operation based on system state.
How does the PCS talk to the BMS?
Over CAN and Modbus, exchanging state-of-charge, charge/discharge limits and protection status with the battery.
