In the rapidly evolving commercial and industrial (C&I) energy sector, businesses seek storage solutions that are not only powerful and safe but also remarkably simple to deploy and operate. The WHES PC-G1 100kW/233kWh All-in-One Energy Storage System (ESS) meets this demand head-on, offering a fully integrated, globally certified package designed for rapid delivery and seamless installation.
Engineered for Simplicity and Economy
The PC-G1's core philosophy is integration. By combining the Battery Management System (BMS), Energy Management System (EMS), HV Box, CATL battery packs, liquid cooling system, and Power Conversion System (PCS) into a single, pre-assembled unit, WHES eliminates complex on-site integration. This all-in-one design drastically simplifies logistics, transportation, and on-site operations and maintenance (O&M), translating into significant time and cost savings from deployment through the entire project lifecycle.
Built on a Foundation of Safety and Trust
Safety is non-negotiable for energy storage. The PC-G1 is rigorously certified to international standards including IEC 62933 and UL9540A, with its safety validated by the stringent UL9540A test. The system incorporates a comprehensive four-level protection strategy (Pack-Rack-PCS-System) and features independent Manual Service Disconnectors (MSD). Integrated smoke and heat detectors, coupled with audible/visual alarms and an aerosol fire suppression system, provide multi-layered safety assurance. This robust safety architecture has earned the confidence of industry professionals, as noted by an anonymous EPC who stated, "I'm absolutely confident in the safety of WHES products; they have obtained comprehensive certifications."
