Solutions

Battery energy storage, from 5 kWh to multi-megawatt

Four product platforms covering every scale of storage project, all built on lithium iron phosphate (LFP) cells, multi-level battery management and a common cloud monitoring layer.

Range of Optimal Green Power battery storage systems: rack cabinet, residential tower, industrial cabinet and container block

Desk & rack storage

Technical rooms, edge sites and mission-critical loads

Cabinet and 19" rack systems for installations where floor space is limited and access must be controlled. Front-access modules, integrated BMS and hot-swappable design simplify maintenance without shutting down the load.

  • 19" rack and free-standing desk formats
  • Hot-swappable modules, front access only
  • Integrated fire detection and forced-air cooling
  • Modbus TCP and CAN interfaces for existing SCADA
