Huawei has established itself as the world’s largest solar inverter manufacturer, holding the number one global position for ten consecutive years alongside Sungrow. The company’s FusionSolar division combines decades of telecommunications expertise with cutting-edge solar innovation, resulting in inverters that feature AI-powered monitoring, advanced arc fault detection, and industry-leading efficiency ratings approaching 99%.
However, UK homeowners considering Huawei inverters face an important development. In late 2025, Huawei announced its withdrawal from the UK residential solar and battery storage market. From January 2026, Huawei inverters, batteries, optimisers, and accessories are no longer available through UK distributors, though the company has confirmed that all existing warranties will be honoured and UK-based support teams will remain operational.
This review examines the complete Huawei FusionSolar product range, including the SUN2000 hybrid inverter series, LUNA2000 battery systems, and smart optimisers. We provide guidance for UK homeowners with existing Huawei systems as well as recommendations for alternatives including Sungrow, GivEnergy, and GoodWe inverter.
Huawei exited the UK residential market in December 2025. New installations are no longer available through UK distributors. Existing warranties are fully honoured and UK support remains operational.

Summary
Huawei established itself as the world’s leading solar inverter manufacturer through exceptional R&D investment, innovative technology, and industry-leading efficiency. The FusionSolar ecosystem offered unique features including partial optimiser deployment, AI-powered monitoring, and independent battery module optimisation that set it apart from competitors.
The company’s exit from the UK residential market in late 2025 represents a significant change for UK solar installers and homeowners. While existing system owners can be reassured that warranties will be fully honoured and UK support teams remain operational, new installations are no longer possible through standard UK distribution channels.
For those planning new solar installations, alternatives including Sungrow, GivEnergy, and GoodWe offer comparable technology with strong UK support networks.
