Huawei has launched FusionSolar 9.0, an integrated solar-plus-storage platform with smart inverters and AI-driven management to enhance grid stability and efficiency in weak grids with high renewable penetration. The platform includes a kilovolt-class AC system, grid-forming smart string inverters, and an AI layer for real-time analysis and optimization, aiming to transform solar plants into active grid-support assets. Designed for large ground-mounted projects, FusionSolar 9.0 offers high efficiency, protection, and fault localization capabilities, making it a valuable tool for improving stability in weak grids with high shares of renewables.
