Flex-ESS 250

AceOn supply a 250kVA 104-832kWh Battery Storage Solution with

additional 1MWh+ Battery Storage Capacity options

AceOn Group have partnered with MSP to provide industrial battery solutions. The FLEX-ESS 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-ESS 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-ESS provides the ultimate, flexible approach for most applications.

For the full spectrum of energy demands

Off Grid

From microgrid to industrial power, the FLEX-ESS system gives you the power you need when you need it. With the ability to deliver 100% capacity to the AC load and still store excess solar, direct line control and optimise any fuel derived generation, keeping OPEX to a minimum and maximising revenue.

  • 250 kVa Hybrid inverter
  • Grid forming and following
  • Integrated storage by KORE Power
  • Black start
  • Generator reserves displacement
  • Ramp rate control
  • Power factor correction
  • Load and peak shaving
  • EV Charging

On-Grid/Grid Services

With ultra-fast response bi directional 4 quadrant operation, the FLEX-ESS 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.

  • Voltage control and droop
  • Power factor control
  • Reactive power (VAR)
  • Frequency regulation and response
  • Peak shaving
  • Curtailment avoidance
  • Scheduled shifting or islanding
  • Accurate and fast ramp rate control
  • Black start and UPS
  • Remote command power and operation
  • 24hr automated system monitoring
  • EV Charging

Housing System

Modular and expandable, the FLEX-ESS offers installers a plug-and-play, factory-built-and-tested, easily-installed solution. The thermally insulated and ultra durable housing ensures ideal climatic conditions for the EES. Parasitic loads are minimised by water cooling the power conversion technologies and, DC split air HVAC for the KORE Mark 1 batteries results in class leading efficiencies.

  • Ultra low foot print – 2.7mx 3.4m x 1.5m (HxWxD)
  • Easily transported on site by forklift or telehandler
  • Factory-built-and-tested
  • Secure and ultra-durable
  • Thermally optimised
  • Maximum energy density
  • Flexible layout options
  • Plug-and-play, delivery to commissioning hours not days
  • IP 64 rated enclosure

As well as the compact and modular design, the unit provides:

  • Hybrid high-power multi-port inverter eliminates need for separate solar & storage inverters eliminates need for separate solar & storage inverters
  • Market leading KORE Power energy storage
  • Up to 340kW of solar energy (single unit)
  • Significant reduction in OPEX and installation costs
  • Grid services
  • Off-grid/on-grid
  • UPS/SRT/Grid bridging system
  • Visually unobtrusive and available in any RAL colour
  • Enabling EV charging

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 250kVA of 3 phase AC Power with blocks of 104kWh of storage to a maximum of 832kWh (double stacked). Additional 250kVA 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.

Monitoring

Capable of integration with existing plant infrastructure using Industrial Ethernet communication protocols (for example Modbus TCP/IP, SCADA) for remote control and monitoring of the system from a centralised control room.

Battery health is continuously monitored via the KORE Power SRCs, providing real-time data of battery system health and performance.

Our bespoke software allows an operator to monitor total system performance from input power source to output on the proprietary HMI screen, or remotely via Industrial Ethernet protocols.

The system is also supported with remote performance monitoring for servicing and maintenance.

System security

System is compliant with IEC 62351 – standard for security in energy management system and associated data exchange.
