HANCHU ESS Receives Top Brand PV Seal in the UK for Both Inverter and Storage

Bonn / London, July 6th, 2026. HANCHU ESS, the energy storage brand of Guoxia Technology Co., Ltd., has been awarded the Top Brand PV seal by EUPD Research in both the Inverter and Storage categories for the UK market. The recognition is based on the findings of EUPD Research’s annual InstallerMonitor^©, in which solar and storage installers across the UK are surveyed on their brand awareness, brand portfolio, brand installations, and willingness to recommend. For HANCHU ESS, this marks the first time receiving the seals, underlining the brand’s growing footprint and reputation in the UK renewable energy sector.

Installer confidence reflected in results across both categories

The survey data paints a compelling picture of HANCHU ESS’s standing among UK professionals. In the Inverter category, the brand achieved a Net Promoter Score (NPS) of 60 alongside a portfolio depth of 41%, one of the highest figures in the sample. Portfolio depth measures the share of a given brand’s products within an installer’s total installed capacity, making it a direct indicator of how regularly and consistently professionals choose a brand for their actual projects, not just whether they know it exists. In the Storage category, results were equally strong, with an NPS of 60 and a portfolio depth of 45%, again among the highest recorded. Achieving these figures across both product categories simultaneously, and as a first-time awardee of the seal, places HANCHU ESS among a select group of brands that UK installers have come to genuinely rely on.

Intelligent energy management at the core

HANCHU ESS supports its installations with the iESS platform, an AI-powered cloud-based energy management system that coordinates generation, consumption, and storage across cloud, edge, and device layers. Through iESS, installers and end users benefit from AI-driven energy optimisation strategies and intelligent remote customer service. The platform also connects with Nord Pool, Europe’s leading power exchange, covering markets across Central and Western Europe as well as the Nordics and Baltics, allowing users to optimise energy use based on live electricity price signals. In the UK, iESS supports a virtual power plant collaboration with Octopus Energy, enabling smarter grid interaction for end users.

Alongside the platform, HANCHU ESS recently launched the POLA-16L-P, a floor-standing battery storage unit. The system delivers 200A rapid charge and discharge capability, includes built-in auxiliary heating for operation in low-temperature environments, and supports up to 16 units in parallel with intelligent automatic addressing. Safety features include a seven-layer battery management system, thermal aerosol fire suppression, and a pressure relief valve.

The company’s growing European presence is further supported by local subsidiaries in the United Kingdom and the Netherlands.

Markus A.W. Hoehner, CEO of EUPD Research, comments: “HANCHU ESS has made a strong impression on UK installers, and the numbers reflect that clearly. A portfolio depth of 45% in Storage and 41% in Inverters, for a first-time Top Brand PV recipient, tells you that professionals are not just familiar with this brand but are actively building their businesses around it.”

Robin Hu, UK Director at HANCHU ESS adds: “Being recognised by UK installers through the Top Brand PV seal means a great deal to us. The UK is a strategically important market, and the fact that our products make up such a significant share of our partners’ installed portfolios speaks to the confidence they place in our technology every day. We remain committed to growing alongside them and continuing to bring intelligent, reliable energy storage solutions to the market.”
