常规PCS有缝离网切换方案（>1min）
STS + PCS Seamless Switching Solution (<20ms)
Use STS for grid/battery second-level switching plus PCS for grid-forming off-grid operation, allowing the energy storage cabinet to replace or reduce the configuration of traditional UPS and diesel generators. Switching time ≤ 20 ms, single system 125 kW to 750 kW, up to 6 cabinets in parallel, off-grid operation ≥ 2 h (extendable to 8 h).
Quick Switchgear + PCS Seamless Switching Solution (<20ms)
Explains how Hoenergy D-Cube energy storage paired with Enjoy EQS fast transfer switches achieves grid-to-island switching within ≤20 ms (125 kW PCS) or ≤30 ms (215 kW PCS) using VSG synchronization and natural commutation.
