1Solis is the #1 residential single-phase inverter brand by shipments (Wood Mackenzie 2024) and 3rd largest inverter manufacturer globally with 100+ GW shipped.
299.7% reliability rate with fanless silent operation – first inverter manufacturer to complete independent PVEL reliability testing.
3Excellent battery flexibility – compatible with Pylontech, Dyness, Fox ESS, BYD and other third-party batteries, unlike proprietary systems.
4Budget-friendly pricing at 10-20% less than mid-range brands, though standard 5-year warranty is shorter than GivEnergy (12 years) or Fronius (10 years).
Solis has established itself as one of the most popular inverter brands in the UK market, offering a compelling balance between affordability and performance. Manufactured by Ginlong Technologies, a publicly listed Chinese company founded in 2005, Solis inverters have achieved significant global recognition, ranking as the number one residential single-phase inverter brand by shipments according to Wood Mackenzie in 2024, and holding third position among global inverter manufacturers.
The Solis approach focuses on delivering reliable performance at competitive price points rather than competing directly with premium European brands on cutting-edge features. This strategy has proven successful, with the company achieving over 100 GW of cumulative shipments by 2024 and earning BloombergNEF Tier 1 status. The brand has also been recognised as a Top PV Brand by EUPD Research for nine consecutive years from 2016 to 2024.
This review examines the complete Solis product range available in the UK, including the S6 generation string inverters, the 5G and S6 hybrid inverters for battery storage applications, and the commercial three-phase range. We assess specifications, real-world performance, SolisCloud monitoring capabilities, battery compatibility including Pylontech and other LFP options, warranty terms, and how Solis compares to alternatives like GivEnergy and Sungrow.

Solis has earned its position as one of the most popular inverter brands in the UK by delivering reliable performance at competitive prices. The company’s 20-year track record, combined with its scale as the third-largest inverter manufacturer globally, provides reassurance that products and support will remain available for the long term. The stated 99.7% reliability rate and completion of independent PVEL testing demonstrate genuine commitment to quality despite the entry-level pricing.
The main trade-off with Solis is the shorter 5-year standard warranty compared to competitors offering 10 to 12 years as standard. While extended warranties are available up to 20 years, these represent additional costs that narrow the price advantage. The SolisCloud monitoring platform has improved significantly and now offers comprehensive features including remote control of hybrid systems, though some users report that UK technical support response times could be better.
For UK homeowners seeking maximum value, Solis represents an excellent choice, particularly when paired with Pylontech batteries for a proven combination. The fanless design ensures silent operation, and the IP65 rating provides flexibility for indoor or outdoor installation. Commercial buyers benefit from the extensive three-phase range up to 125 kW with features like generator support and fast UPS switchover.
