GoodWe PCS series are three-phase energy storage inverters (PCS) designed for commercial and industrial installations, where stable operation and flexible integration with the BESS system are crucial. The equipment features a modular structure, which facilitates configuring the setup to meet project requirements and enables more efficient maintenance. The PCS supports operation both in grid-connected (on-grid) and off-grid modes, making it suitable for backup power systems and applications requiring greater energy independence.
In practice, the greatest advantage is intelligent control of cooperation with the grid- the system can achieve full load under phase imbalance, which helps in facilities with unevenly distributed loads. Integrated protections and a high degree of protection for the enclosure support safe operation in more challenging conditions.
For monitoring and integration with automation, communication interfaces (including Ethernet, RS485, CAN) are available, facilitating supervision and remote management. The PCS series is intended for investors building energy storage for optimizing self-consumption, reducing peak power, and improving power quality.

Pros and cons
The PCS series achieves a peak efficiency of 98.6% (verified for the ESA/PCS 125 kW model), placing it among the leading competitors in the C&I segment: The Sungrow SC200UD achieves 98.5%, and the SMA Sunny Central Storage achieves up to 98.7%. The overall system efficiency (RTE) is 92%, which directly impacts the cost-effectiveness of the peak shaving model.
The 215 kW model maintains its rated power up to 45°C ambient temperature, while the 125 kW model can handle a 2-hour overload of up to 137.5 kW (1.1× P_nom) at 40°C. This is a key parameter for industrial installations and facilities in climate-sensitive areas, where most competitors already derate at 40°C.
The 215 kW model incorporates both a reactive power compensation (SVG) and a synchronous virtual generator (VSG) function, and supports blackstart capabilities. This means it is ready to contract system services (frequency regulation, voltage support) with the grid operator without the need for additional intermediary equipment - a significant advantage over basic PCS offered by competitors.
Up to 24 units of the 215 kW model can be connected in parallel, resulting in a 5 MW system. This architecture simplifies the design of large utility-scale facilities and reduces commissioning time compared to solutions that require a separate controller for aggregation.
The IP66 enclosure, with C4/C5 resistance according to ISO 12944, allows for installation in marine, port, and heavy-industrial environments without the need for additional external enclosures. EMC Class B certification (more stringent than the required Class A) reduces the risk of electromagnetic interference in facilities with sensitive control and measurement equipment.
The C&I 125 kW model supports DC voltages of 670-1000 V and is optimized for 280-320 Ah batteries. This makes it compatible with the rapidly growing segment of 314 Ah+ and 560 Ah (prismatic LFP) batteries, which are becoming increasingly common in BESS tenders in 2025. The Sungrow ST2752UX and Huawei LUNA2000-C models already support a wider range of DC voltages (600-1500 V).
The official datasheet for the PCS series is not directly available for download from the en.goodwe.com website - contact with sales is required. This makes it difficult for investors and financing banks to quickly conduct due diligence, as the standard has become full technical documentation available online (such as with Sungrow or SMA).
