The new solution combines PCS hardware, plant-level controls and AI-based energy management.
Huawei Digital Power has launched a new generation of smart string grid-forming power conversion system (PCS) at SNEC 2026 in Shanghai, expanding its grid-forming technology portfolio across energy storage, PV and load-side applications.
The company presented the solution during its FusionSolar strategy and product launch event on June 3 under the theme “Building the green power driving force for an intelligent world.” The announcement also covered the FusionSolar Agent energy AI architecture.
The new PCS platform includes a 430 kW smart string grid-forming PCS, an intelligent sub-array controller, an intelligent plant controller and an intelligent plant management system. Huawei said the system is designed as a core control unit for energy storage plants, integrating battery management and grid-stability functions.
The 430 kW PCS uses a 1,000 V AC architecture and supports a DC operating voltage range of 550 V to 1,500 V. According to Huawei, the wide voltage range enables compatibility with lithium-ion, sodium-ion and other battery chemistries. The company claims a system cycle efficiency of 97.8%, compared with an industry average of 96.7%, while the power converter efficiency reaches 99.35%.
