Solis, a global manufacturer of solar inverters and a leading provider of energy storage solutions, has announced that its first commercial battery installation in the UK is up and running at The Robert Jones and Agnes Hunt (RJAH) Orthopaedic Hospital. The project, delivered by ZLC Energy, combines large-scale solar generation with advanced battery storage technology to significantly reduce energy costs, lower emissions, and optimise how energy is being used at the site.
The installation features six 109kWh Solis PrimePower commercial batteries, each connected to a Solis 50kW hybrid inverter. All working in parallel, the system is providing more than 600kWh of storage capacity, allowing the hospital to make better use of the solar energy being generated.
Instead of the excess solar being limited during the day, energy can now be stored and used later during high demand periods or overnight; helping lower electricity costs while strengthening energy resilience across the site.
The project highlights the growing appetite for commercial battery storage across Europe, particularly in environments where solar energy is often overproduced and unable to be used immediately, or where reliable, uninterrupted power is essential.
Mark Smith, Director at ZLC Energy, said:
“Working with Solis on this project has been a very positive experience from start to finish. The level of technical support, responsiveness, and collaboration throughout the project has been excellent, helping ensure the installation was delivered smoothly and successfully.
“The wider renewable energy system we’ve delivered here will now generate between 2.5 and 3GWh of electricity annually — enough to offset approximately 75% of the hospital’s electricity usage — reducing carbon emissions by approximately 600 tonnes annually.”
Sandy Woodward, Solis’ European General Manager, added:
“This project is a huge milestone for Solis, representing our first commercial battery storage installation in the UK at a time when demand for energy storage is growing rapidly across Europe. Customers are increasingly looking beyond solar generation alone and want complete energy solutions that help them maximise self-consumption, reduce electricity costs, and manage energy more intelligently. Storage is quickly becoming a core part of modern energy systems, particularly across commercial and public-sector projects like this one.
“With more than 20 years of experience in solar technology and a strong installed base across Europe, Solis is in a fantastic position to support that transition through a complete ecosystem of inverters, storage, and smart energy management.”
Ben Huband, Estates Compliance & Energy Manager at The Robert Jones and Agnes Hunt Orthopaedic Hospital NHS Foundation Trust, commented:
“This project marks a significant step forward in how we manage energy across the hospital estate. By combining large-scale solar generation with battery storage, we’re able to make better use of the renewable energy being produced on site, helping reduce our reliance on grid electricity, lower costs, and support our wider sustainability ambitions. Working with partners such as ZLC Energy and Solis has enabled us to implement a solution that is practical, resilient, and built around the needs of a busy healthcare environment."
Designed for Commercial Energy Storage Applications
Solis’ commercial battery storage solutions are designed to support a wide range of commercial and industrial applications, helping organisations maximise solar self-consumption, reduce electricity costs, and manage energy more intelligently. In existing grid-connected photovoltaic installations, commercial energy storage systems can be deployed through AC coupling to significantly increase system self-consumption, with some applications achieving rates of up to 95%.
Designed for demanding energy environments, Solis commercial storage solutions combine high-performance storage with flexible integration and intelligent energy management, supporting applications such as peak shaving, time-of-use optimisation, and backup operation where required. When paired with compatible energy management systems, it can also respond automatically to dynamic pricing frameworks, optimising charge and discharge behaviour in markets where electricity tariffs change every 15 minutes.
With the successful commissioning of the RJAH installation, Solis continues to expand its presence within the European commercial storage market while supporting organisations looking to accelerate their transition towards cleaner, more independent energy systems.
