Socomec Energy Storage Solutions

Leveraging its strong historical expertise in both AC & DC Power Monitoring, Power Switching and Power Conversion, Socomec has invested over the past decade in Energy Storage applications, participating in many experimentations with major utilities, battery manufacturers, energy management software editors and pioneering ESS system integrators.



Modular Architecture

Custom Battery Energy Storage Solution based on Standard equipment

  • SUNSYS bi-directional converters from 66 to 1000 kVA, for on-grid and off-grid application, with transformer
  • SUNSYS Battery racks of 91,3kWh, up to 16 racks, BBMS integrated, power supply box
  • SUNSYS AC cabinet with surge protection, power monitoring, power switching and ground connection for off-grid applications
  • SUNSYS DC with ultra-rapid fuse protection, insulation monitoring and power switching
  • SUNSYS Control module with metering and power monitoring, battery data logging, Islanding controller (for resilient microgrids) and remote management

Container Integration

Container integration is an all-in-one integrated solution, limiting on-site preparation and working time. The full Container configuration is ready to connect on the grid, and passed through a Factory Acceptance Test quality process.

The choice of Maritime ISO container allows the BESS to be shipped all around the globe – a highly robust technical room.


Based on standard container engineering integration, the solution may be adapted to specific needs and requirement:

  • Extreme external ambient conditions, for example high level of container isolation, cooling system redundancy, protection against saline environments…
  • PV installation integration, hosting of an additional cabinet for the conversion system and the protection devices of the solar panels
  • Integration of a transformer for a direct connection to the medium voltage
  • On-demand container design for hosting non-standard equipment, for example specific models of batteries or additional AC-Cabinet for protection and control of multiple production sources
  • Integration of 3rd party devices for control & automation of all the battery energy storage system
