Our Flex-ESS250 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 Hithium Storage Modules and our ground-breaking FLEX Inverter, Flex-ESS250 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-ESS250 provides the ultimate, flexible approach for Commerical and Industrial 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 Primary housing contains 250kVA of 3 phase AC Power with 366kWh of storage per rack.

Additional energy expansion modules are available with each housing containing 732kWh 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.

Flex-ESS250 for a full spectrum of energy demands.

On Grid/Grid Services

With ultra-fast response bidirectional 4-quadrant operation, the Flex-ESS250 system offers ACTIVE and REACTIVE power services to both industrial and commercial operators. With only the highest quality components and water cooling, the system delivers outstanding up time, minimal OPEX and > 20 years service life, ensuring long term reliable access to those current and future revenue streams.
