PWS1-135M: 135kW C&I PCS Module for Low-Voltage Grid

The PWS1-135M is a 135kW power conversion system (PCS) module designed for low-voltage grid-connected commercial, industrial, and microgrid applications. It addresses key pain points in C&I energy storage, such as product stability, environmental adaptability, and system cost reduction. The module achieves 98.3% one-way charging/discharging efficiency and supports high-temperature derating up to 55°C, IP65 C5 anti-corrosion, and noise levels of 70dB. It offers grid adaptability for 400V, 480V, and 208V AC voltage levels, with the ability to connect and operate at THDU up to 25%. The PWS1-135M features a three-phase four-wire topology, handling 100% unbalanced loads without a transformer, and supports parallel operation of up to 8 units for AC/DC and 12 units for off-grid communication. Its compact dimensions (720x960x265mm) allow for horizontal, side, or vertical installation. The module is available in CN, EX, and NA versions, with an external BCU integrated high-voltage box option. It is suitable for integrated cabinets, containers, and all-in-one solutions, reducing initial and O&M costs while maximizing lifecycle returns.
