The most flexible large scale energy storage solution on the market today

  • Utility-Scale Modular Storage System

  • 1Hr to 4Hrs +

  • Ultra-Low Lifetime Op-Ex

  • Ultra-Low Installation Cost/Time

  • Manufactured in Great Britain


Our Flex-ESS1000 integrated energy storage system is a fully factory-built and tested, high-density, modular energy solution. It reduces project risk and cost thanks to its simple installation, small footprint, and lightweight construction. It also offers ultra low operating costs thanks to its enclosed cooling and IP64 housing. Integrating KORE Power Mark1 storage modules and EPC’s CAB1000 inverter, Flex-ESS1000 achieves an industry-leading, density-optimising footprint for applications where space is constrained or at a premium. Working with multiple power sources and output configurations, the Flex-ESS1000 provides the ultimate, flexible approach for scaleable ESS applications.
