IN Brief:
- Socomec has launched SMARTSYS C260 and SMARTSYS M5000 battery energy storage systems.
- The C260 provides 125kVA and 261kWh in a compact cabinet format for commercial and industrial sites.
- The M5000 combines a 5MWh LFP battery container with a medium-voltage skid integrating PCS, control cabinet, switchgear, and transformer.
Socomec has expanded its energy storage offer with the launch of the SMARTSYS range, covering compact cabinet-based storage and containerised medium-voltage systems for commercial, industrial, infrastructure, and grid-scale applications.
The range includes the SMARTSYS C260 and SMARTSYS M5000. The C260 is an all-in-one cabinet system combining power conversion and battery storage, while the M5000 is a containerised battery energy storage system paired with a medium-voltage conversion skid for larger infrastructure and grid-service projects.
Delivering 125kVA and 261kWh in a compact design, the SMARTSYS C260 has a footprint around half that of previous models. It is designed for commercial and industrial environments, including EV charging sites and buildings with on-site renewables, and supports both on-grid and off-grid operation. Parallel configurations can extend deployment up to 1MVA and 2MWh.
At the higher-power end of the range, the SMARTSYS M5000 combines a 5MWh lithium iron phosphate battery container with a pre-assembled medium-voltage skid integrating the power conversion system, control cabinet, switchgear, and transformer. The system is available from 2.5MVA / 5MWh and can be configured up to 5MVA / 20MWh behind a single transformer.
The M5000 is designed for front-of-the-meter and behind-the-meter applications, including grid services, EV charging infrastructure, and large-scale energy management for distribution system operators, transmission system operators, independent power producers, and major infrastructure users. Its pre-assembled and factory-tested architecture is intended to reduce on-site engineering complexity, limit system interfaces, and support faster installation and commissioning.
Storage projects are increasingly judged on integration quality as much as installed battery capacity. Containers, inverters, transformers, switchgear, protection systems, fire detection, cooling, controls, communications, metering, and market interface software all have to operate as one asset. A weak interface between those systems can reduce availability, slow commissioning, increase maintenance demand, or restrict market participation.
Socomec’s architecture reflects that more integrated storage environment. The M5000 brings the battery container and medium-voltage conversion equipment into a repeatable configuration, while the SMARTSYS range also includes SoLive PRO BESS for remote monitoring and battery data analytics. The platform is designed to visualise, analyse, and optimise storage performance across multiple sites.
That digital layer is becoming more valuable as storage assets enter more complex revenue and operating models. Early battery projects were often designed around fast-response ancillary services, while newer assets are expected to support wholesale trading, balancing, constraint management, capacity support, co-location with renewables, and local network flexibility. Each use case places different demands on cycling, state of charge, ramping, degradation management, and dispatch strategy.
Project scale is also rising. EDF’s optimisation agreement for the Hams Hall battery project showed how large UK assets are moving toward longer-duration operation, active optimisation, and multi-service market participation. Storage hardware now has to be designed for that operating environment from the outset.
Safety remains central to acceptance and long-term operation. The M5000 includes LFP battery technology, liquid cooling, flame-retardant cells, heat-resistant enclosure design, early fire detection, compartment isolation, fire suppression, deflagration venting, forced ventilation, water spray cooling, emergency stop, and lightning protection. Those features sit alongside conformity with relevant safety, EMC, transport, environmental, communications, and grid-code standards.
The combination of physical integration, electrical design, safety architecture, and software monitoring points to the next phase of BESS deployment. Storage is no longer treated as a simple containerised add-on. It is becoming a power-system asset that must satisfy grid interface requirements, investor performance expectations, planning scrutiny, and operational risk controls over long service lives.
Socomec will present the SMARTSYS range at Intersolar Europe in Munich from 23 to 25 June, with the C260 on the show floor and a preview of the M5000 and SoLive PRO BESS monitoring service. Product information is available through the SMARTSYS M5000 page.
As storage pipelines expand, standardised and pre-tested medium-voltage architectures can reduce part of the engineering friction between project consent, grid connection, commissioning, and operation. Availability, safety performance, and dispatch quality will determine how far that standardisation translates into bankable storage delivery.
