All-in-One Energy Storage System: A Fully Integrated, High-Safety, Rapid-Deployment Solution for Commercial & Industrial Applications
The WHES PC-G1 100kW/233kWh All-in-One Energy Storage System is a high-performance, plug-and-play energy storage solution meticulously engineered to address the energy management needs of global commercial and industrial (C&I) applications. It represents the latest achievement from WHES in integrating energy storage technology with a focus on safety, economy, and ease of deployment, offering customers a complete, reliable, and high-return storage product.
The core design philosophy of the PC-G1 is "High Integration and Rapid Deployment." The system adopts an all-in-one design, where key components—including lithium-ion battery packs, the Battery Management System (BMS), Energy Management System (EMS), High-Voltage Box (HV Box), Power Conversion System (PCS), and liquid cooling thermal management system—are pre-integrated at the factory into a single, standardized, protective enclosure. This design drastically simplifies on-site engineering by shifting complex system integration work from the construction site to a controlled factory environment, ensuring higher product quality consistency and reliability. The most direct benefit is the reduction of on-site installation time to less than one day, significantly lowering total installed costs and project timeline uncertainties. This allows customers to activate their storage assets and begin generating returns much faster.
At the heart of its energy storage capability, the PC-G1 utilizes globally leading CATL 280Ah Lithium Iron Phosphate (LFP) cells. These cells, with a nominal voltage of 3.2V and capacity of 280Ah, form the basic building blocks. Configured in a 1P52S battery pack arrangement, they create a DC-side rated voltage of 832V (operating range 650-949V) and a total system energy capacity of 233kWh. While the LFP chemistry itself offers excellent thermal stability and cycle life, WHES implements a Parts-Per-Billion (PPB) level quality control for the cells, striving to minimize cell failure rates to an exceptionally low level, thereby ensuring the long-term operational safety and durability of the entire storage system from the source.
On the grid-connected AC side, the system delivers a rated power of 100kW. It supports a three-phase 400V voltage (with neutral for auxiliary power only), with a wide operating voltage range of 360-440V and a frequency range of 45-55Hz, ensuring compatibility with low-voltage grid standards in major global regions. The power conversion topology employs a non-isolated design, achieving high conversion efficiency (a common feature of high-efficiency PCS units as indicated in related materials) and supports full power factor operation from -1 to +1. This enables not only active power charge/discharge but also reactive power support for local power factor correction. Its output current total harmonic distortion (THDi) is kept below 3%, ensuring grid-friendly integration and preventing power quality pollution.
Safety and reliability are paramount in the PC-G1's design, which incorporates a multi-layered, hardware-and-software integrated protection framework. In terms of certifications, the system has obtained several critical international certifications, including UL9540A (Fire Safety Testing for Energy Storage Systems), IEC 62619 (Safety Requirements for Industrial Battery Cells and Systems), and UN38.3 (Safety Testing for Lithium Battery Transportation). It also complies with key regional grid-connection standards such as EN 50549 (EU), VDE 4105 (Germany), G99 (UK), and AS4777.2 (Australia), clearing regulatory pathways for global deployment. The hardware safety design features a four-level protection architecture ("Cell-Pack-Rack-PCS-System") and includes an independent Manual Service Disconnector (MSD). The enclosure is equipped with integrated smoke and heat detectors, audible/visual alarms, and an aerosol fire suppression system, forming a combined active warning and passive suppression fire protection system. Optional flammable gas detectors and ventilation plates further enhance safety in specific environments.
The system's physical design is built for harsh industrial conditions. It boasts an Ingress Protection rating of IP55, effectively preventing dust ingress and water jets from any direction. With a corrosion resistance rating of C5, it is suitable for highly corrosive industrial and marine atmospheres. It operates reliably across a wide temperature range from -20°C to 55°C (with derating above 45°C), adapting to climates from cold to tropical. Operating noise is kept below 75 dB, minimizing environmental impact. Its dimensions are 1400mm (W) * 1350mm (D) * 2100mm (H), with a weight of approximately 2.7 tons, designed for floor-standing installation. Thermal management employs a hybrid cooling approach combining intelligent air cooling (for the PCS) and liquid cooling (for the batteries), ensuring the cells operate within an optimal temperature range to slow degradation and extend lifespan.
In terms of intelligence and connectivity, the PC-G1 is powered by WHES's proprietary WHES OS energy management system. Users can monitor and operate the system via the onboard LCD screen, LED indicators, or a mobile app. The system supports multiple communication protocols such as RS485, CAN, and Ethernet, facilitating seamless integration with higher-level energy management platforms, photovoltaic inverters, building automation systems, and other equipment. This enables a variety of advanced applications, including photovoltaic self-consumption, peak shaving and valley filling, demand management, backup power, and participation in grid ancillary services. Its typical application scenarios encompass shopping malls, farms, factories, and communities—venues sensitive to energy costs or with critical requirements for power supply continuity.
In summary, the WHES PC-G1 100kW/233kWh All-in-One Energy Storage System is a flagship C&I storage product that integrates top-tier supply chain components (CATL cells), passes rigorous international safety certifications (UL9540A), features a highly integrated design for rapid deployment, and is equipped with an intelligent management system. It is committed to providing customers with a safe, reliable, efficient, and easy-to-deploy "turnkey" energy storage solution, helping users effectively manage energy costs, enhance power resilience, and contribute to a sustainable energy future.
