Following Socomec’s successful introduction of the SUNSYS HES L, a native outdoor energy storage system ranging from 100 kVA / 186 kWh to 600 kVA / 1674 kWh, the specialist in source switching, energy conversion and measurement is now launching a higher power version.
Socomec’s new SUNSYS HES XXL offers a power range from 1 MVA / 1 MWh to 6 MVA / 20 MWh per system with the ability to achieve higher power when installed in parallel. This is particularly suitable for storage systems installed in co-location sites with renewable energy production or for use with grid support services.
With this new offering, Socomec aims to deliver projects of several tens of MW and address the needs of the Front Of The Meter (FTM) market, which constitutes a significant and rapidly growing share of storage projects worldwide.
SUNSYS HES XXL: a wide range of scalable systems – made simple
Thanks to its design, SUNSYS HES XXL offers a high degree of configurability. This modular storage system is based on:
- Two standard cabinets: a conversion cabinet (C-Cab) and a battery cabinet (B-Cab).
- A DC distribution cabinet for systems with more than 8 battery racks.
- As well as a "custom-designed" control cabinet, customisable on a case-by-case basis to meet the requirements of every installation.
This flexibility means that the solution can be tailored to most grid storage applications such as the optimisation of renewable energy integration, frequency regulation and backup.

A focus on safety
Also, as with SUNSYS HES L, this new offering consists of a CATL EnerOne battery cooled by liquid, using LFP (Lithium Iron Phosphate) technology, capable of withstanding thermal runaway and compliant with the UL 9540A standard
Furthermore, the cabinet also incorporates an integrated fire detection and extinguishing system for enhanced safety.
Expert services for optimised storage asset management
The SUNSYS HES XXL offering is accompanied by a complete range of services led by a team of experts. The comprehensive services include pre-sales assistance, including requirement analysis, technical pre-project design and solution evaluation. Complete solution design support and project fulfilment services are available through co-engineering with the client, alongside testing and commissioning support, operation and maintenance services.
Preventive maintenance contracts and warranty extensions are available to ensure the reliability and performance of the system, as well as to optimise its lifespan.
The daily management of the system can be further simplified by connecting it to the cloud, providing 24/7 operator monitoring through the SoLive mobile application and indicator tracking via a customised dashboard.
