Product description
The WHES PC-G2 (IA-250kW/500kWh) is a C&I energy storage system pairing a 250 kW PCS with a 509 kWh LFP battery cabinet (CATL 306Ah cells, 1P×52S) for commercial and industrial applications — peak shaving, dynamic expansion, and fast frequency response. It uses a modular AC/DC design with 2/4/6/8-hour configurations and scales to 6 units in parallel (1.5 MW / 3 MWh). On the AC side it delivers 250 kW at 400V, 3/N/PE, with THDi <3% and full ±1 power factor; the battery runs at 832V nominal (728–936V) with liquid cooling and smart air cooling on the PCS. Safety is layered: 3-tier fire protection (smoke/heat/gas detection, aerosol and sprinkler suppression, explosion venting), rated IP67 battery pack / IP55 cabinet / IP65 PCS, with C5 corrosion class and UL9540A + VDE 4110 certification. Floor-standing, −20 to +55 °C, under 65 dB, with RS485/CAN/Ethernet communication.
