EP Energy’s EPGW2/3/6/9 Power Distribution Cabinets are engineered as the core centralized energy management solution for commercial and industrial (C&I) energy storage systems, offering a scalable 220kW to 990kW AC low-voltage output for seamless power distribution, control and optimization. Designed to pair perfectly with EP’s EPES233 energy storage cabinets (supporting up to 9 units in flexible deployment), this rugged, high-performance cabinet series enables critical energy management functions including peak shaving, PV storage, time-of-use (TOU) optimization, demand response and anti-reflux protection—becoming the indispensable “nerve center” for integrated C&I energy storage and grid systems.

Core Advantages of EPGW Power Distribution Cabinets

⚡ Flexible Deployment & Scalable Power

Available in four tailored models—EPGW2 (220kW)、EPGW3 (330kW)、EPGW6 (660kW)、EPGW9 (990kW)—the series scales effortlessly to match the energy needs of small to large C&I facilities, from commercial complexes to industrial parks. It supports 1-9 EPES233 energy storage cabinet units in flexible parallel deployment, with a maximum combined power of 990kW, allowing businesses to expand their energy storage infrastructure phased and align capacity with growing power demands—no full system redesign required. All models share a unified appearance style with EPES233, ensuring seamless on-site integration and a streamlined installation layout.

📊 Complete Functionality for Intelligent Energy Management

The EPGW Series is a one-stop solution for C&I energy control, integrating all core functions needed for modern energy storage systems: anti-reflux protection, peak shaving, PV storage, TOU optimization and demand response. It also features built-in electrical billing and metering capabilities, paired with EP’s cloud EMS (Energy Management System) for real-time data statistics, energy consumption analysis and intelligent power scheduling. This centralized management eliminates the need for separate control and metering equipment, simplifying system operation and enabling data-driven energy cost optimization for businesses.

🔩 High Performance & Industrial-Grade Reliability

Built for 24/7 continuous industrial operation, the EPGW Series features H-level breaking capacity for all main and branch breakers, with a 100kA rated limit short-circuit breaking capacity (Icu) and 70kA rated operating short-circuit breaking capacity (Ics) for the EPGW3/6/9 models—ensuring stable power distribution even under grid fault and short-circuit conditions. A 40kA Imax surge protection device (SPD) is integrated as standard, safeguarding the entire energy storage system from grid voltage surges and lightning strikes, and protecting valuable storage and power equipment from damage.

🌿 Outdoor-Ready Durability & Adaptability

Engineered for the diverse operating environments of C&I facilities, the EPGW Series boasts a high IP protection rating that supports direct outdoor installation, eliminating the need for dedicated indoor equipment rooms and reducing on-site construction costs. Its robust build resists dust, water and industrial environmental wear, while seamless compatibility with EP’s EPES233 liquid-cooled energy storage cabinets ensures the entire energy storage and distribution system operates in synergy—whether deployed in factories, commercial complexes, petrol stations or solar PV parks.

🛠️ Easy Operation & Low Maintenance

Designed with user-centricity in mind, the EPGW Series features a modular internal design for quick component access and maintenance, minimizing system downtime for repairs or upgrades. Its integration with EP’s cloud EMS enables remote real-time monitoring of power distribution status, breaker operation and energy flow data, with alarm notifications for abnormal conditions—allowing operators to troubleshoot and manage the system from any location, reducing on-site maintenance labor and costs. The standardized connection interface with EPES233 also speeds up on-site installation and commissioning, cutting project timelines significantly.
