WHES 125kW/261kWh C&I All In One Energy Storage System PC-G3 is a compact battery storage solution for commercial and industrial facilities. It integrates an LFP battery system, PCS, BMS, EMS, high-voltage distribution and safety functions within a single cabinet.

Configuration IA-125kW/261kWh-CG10 provides 125kW rated AC power and 261kWh battery capacity. It is suitable for manufacturing facilities, logistics centres, retail complexes, office buildings, data centres and other businesses with high or variable electricity demand.

PC-G3 can store energy during periods of lower consumption or more favourable electricity prices and make it available when site demand increases. The system supports peak shaving, load shifting, energy price arbitrage and demand response.

The battery section uses LFP, also known as LiFePO4, cells rated at 3.2V and 314Ah. An energy density of 174kWh/m² and a footprint of approximately 1.5m² make PC-G3 suitable for projects where efficient use of installation space is important.

Its All In One design combines modular high-voltage distribution, BMS, EMS, PCS and intelligent power distribution. Cabinets can be installed directly next to each other, simplifying the layout of larger commercial battery storage systems.

The system supports 110% overload capability and up to 24 units connected in parallel on the AC side. Subject to grid capacity, project design and system control requirements, the total installation can be expanded to 3MW.

Integrated WHES OS EMS uses system data, site consumption and electricity prices to optimise charging and discharging strategies. Available functions include energy price arbitrage, demand response and AI-supported predictive maintenance.

The battery system uses liquid cooling, while the PCS uses intelligent air cooling. PC-G3 operates within a temperature range of -30°C to +55°C, with power derating above 45°C. Its noise level remains below 65dB.

The safety architecture includes three-level fire protection covering detection, suppression and isolation, together with four-level electrical protection and AI-supported monitoring. The cabinet provides IP55 protection.

PC-G3 is a grid-connected C&I Energy Storage System. The PCS is an integrated component of the complete battery storage system; the product is not categorised as a standalone or hybrid inverter.

WHES 125kW/261kWh C&I All In One Energy Storage System PC-G3 is available through the Energetik B2B platform for registered users. It is intended for electrical designers, EPC contractors, system integrators, professional installers and business partners delivering commercial and industrial energy storage projects across the EU.
