Huawei Solar Inverters Leave the UK: What Owners Do Next

Huawei has withdrawn its home solar inverters and batteries from the UK market. The Register reported in September 2025 that Huawei was ending UK sales of its LUNA home battery storage line, and UK installer and review sites say the residential SUN2000 and LUNA2000 range has been unavailable through UK distributors since January 2026. If you already own a Huawei inverter or battery, or an older quote still names one, here is what is confirmed, what is only reported, and what to do next.

What has been reported

The battery exit. According to The Register's September 2025 exclusive, citing anonymous sources, Huawei told UK suppliers on 22 August 2025 that its battery energy storage line would be discontinued locally by the end of 2025. Remaining stock was to be cleared, existing warranties honoured, and distributors would no longer be able to sell extended warranties. Huawei declined to comment when asked to confirm the plans. The report described the decision as commercial, with storage a single-digit percentage of Huawei's UK revenue.

The wider range. UK review sites such as Solar Briton go further, saying residential FusionSolar products (inverters, batteries and optimisers) stopped being available through UK distribution from January 2026. That site also says the reasons have not been officially confirmed. We could not find a public Huawei statement setting out the end date, so treat the exact timing as reported rather than confirmed, and ask your installer or distributor for the current position.

The context. The Register put Huawei's UK revenue at £1.28 billion in 2018 and £188 million in 2024, linking the decline to US restrictions and UK 5G rules. Separately, the security debate around Chinese-made inverters has not been proven to be the reason for the withdrawal; no source we found says it was.

What Huawei kit is (or was) on UK quotes

The home range centres on SUN2000 hybrid inverters paired with the LUNA2000 modular battery. Huawei's own LUNA2000 S1 specification page lists usable energy from 5 kWh up to 20.7 kWh depending on the combination of 5 kWh and 6.9 kWh battery modules, an IP66 rating and an operating range of −20°C to +55°C. That modular design is why Huawei was a common choice for homes that wanted to add capacity later.

Any quote or installation proposal you hold that still names Huawei hardware should be treated as out of date. If an installer says they can still supply it, ask where the stock comes from and who will honour the warranty, because distributors were reportedly barred from selling extended warranties.

If you already own Huawei equipment

Warranties. The Register reported that existing warranties would be honoured, and Solar Briton says the same of UK SUN2000 units sold before the exit. The warranty length you hold is set by your original paperwork, and published figures vary between sources, so rely on your own documents rather than a website summary. Huawei's UK warranty and compliance page links to its warranty overview and query tool.

Security updates. Huawei's UK product-security statements for its residential inverters and LUNA2000 batteries give a “UK Defined Support Period” of five years, running to 31 December 2029. That is a statement about security updates under UK product-security rules, not a warranty, but it is the only dated support commitment we could find from Huawei itself.

Practical steps:

• Keep the installation certificate, invoice, serial numbers and warranty registration in one place, and photograph the inverter and battery labels.
• Register the system with Huawei if you have not, so the warranty is traceable to you.
• Keep the monitoring app connected; it is also how faults are usually diagnosed. Our guide to solar panel monitoring explains what to watch.
• Ask your installer whether they will still service Huawei kit. If they stop, an independent MCS installer can usually quote for support.
• Know what an out-of-warranty failure would cost; our guide to replacing a solar inverter covers the options.

If you were about to buy

Treat the brand as unavailable for new installations and compare current hybrid systems instead. Review sites cited above name SolarEdge, Solis, Fronius and Sunsynk as the hybrid ranges UK installers now fit. Our best solar inverter guide, the Sigenergy vs Sungrow vs Solis comparison and the hybrid inverter buyer guide are the places to start. Whichever brand you choose, ask about UK support, warranty backing and the company's financial footing; the GivEnergy administration showed what happens when a manufacturer disappears.
