The most flexible all in one energy storage solution on the market today
Modular for a flexible approach to energy storage
Market leading power density and efficiency
Ultra-Low Installation Cost/Time
Manufactured in Great Britain
Our Flex-ESS500 hybrid power system is a fully-factory-built and tested, high-density, modular energy solution. It offers reduced project risk and cost thanks to its simple installation, small footprint, and lightweight construction. It also offers low operating costs thanks to its enclosed cooling and durable housing. Integrating KORE Power energy storage and our ground-breaking FLEX Inverter, Flex-ESS500 achieves an industry-leading, optimising footprint for applications where space is constrained or at a premium. Working with multiple power sources and output configurations, the Flex-ESS500 provides the ultimate, flexible approach for most applications.
System Configuration
The FLEX-ESS system can be paralleled to multiple MW level in a highly variable range of storage and power configurations. Each GRP housing contains 500kVA of 3 phase AC Power with stacks of 104kWh of storage to a maximum of 832kWh.
Additional energy expansion modules are available with each box housing upto 1MWh of additional capacity, configurable as required.
With its small footprint, multi box configurations can be arranged to preserve space in limited areas and still be planning friendly or discreet installations in any colour preference.
