LSB (Large Scale Battery) reference platform

The Redflow Large Scale Battery (LSB) reference platform demonstrates a straightforward and proven model for deploying ZBM2 zinc-bromine flow batteries in large energy storage systems. Deployed in a six-metre (20-foot) shipping container, Redflow’s LSB reference platform contains as many as 45 ZBM2 batteries and six 12-kilowatt (kW) Victron Quattro 48/15000 battery inverter/chargers, providing customers with 24/7 monitoring and scalable energy capacity to as much as 450 kilowatt-hours.

The LSB reference platform assists Redflow system integrators to design large energy systems that integrate the number of ZBM2 10kWh batteries and Victron battery inverter/chargers required to supply the customer’s energy storage application.


Product Features

LSB: Tailored large-scale energy storage

  • The LSB reference platform can provide a large AC energy storage solution to meet your needs

LSB: Large and scalable energy capacity

  • Standard six-metre (20 foot) shipping container configuration contains as many as 45 ZBM2 batteries and the required number of Victron battery inverter/chargers. Redflow batteries deliver 3kW continuous power, and 5kW peak, with the LSB system output rating dependent upon the size of the Victron energy cluster deployed in the system.
  • Scalable ZBM2 configurations are available to meet specific customer requirements.
  • When large energy storage is needed, the LSB can be deployed in parallel to form multiple container configurations.

LSB: Inherently safe and smart ZBM2 design

  • ZBM2 batteries contain an inherently non-flammable zinc-bromide electrolyte.
  • ZBM2 batteries contain no risk of thermal runaway due to the physical separation of the cell stack and energy storage tank.

LSB: Robust and long-life ZBM2 design

  • Each LSB contains as many as 45 ZBM2 10kWh zinc-bromine flow batteries.
  • LSB is ideal for renewable energy storage or unstable grids because of its 100% depth-of-discharge characteristics, which mean no battery damage from power outages
  • ZBM2 batteries and LSBs can be stored fully discharged with no required maintenance.
  • ZBM2 batteries and LSBs require no trickle charge when deployed or stored.
  • ZBM2 batteries and LSBs deliver guaranteed energy throughput.

LSB: 24/7 monitoring and diagnostics

  • Redflow ZBM2 batteries in the LSB are monitored and managed by a secure Internet-accessible Battery Management System (BMS), that enables quick and easy remote support. Real-time status information on the battery system can be accessed using the BMS. This data can be accessed using secure web browser access, JSON data queries, CANBus battery status messages or MODBUS-TCP queries.

Flexible Configurations

LSB: ZBM2 BUILDING BLOCKS OF SUSTAINABLE ENERGY STORAGE

The Redflow LSB reference platform assists system integrators to design an energy storage system containing an agreed number of ZBM2 batteries to meet your specific application. The ZBM2 features Building Block Technology and flexible modular design, enabling your integrator to configure an LSB to your requirements.

ZBM2 zinc-bromine flow battery


ZBM2 - where power meets intelligence, delivering sustained energy storage from the world’s smallest zinc-bromine flow battery, monitored and managed online.

Rewriting battery rules. 100% storage. 100% available

Redflow’s ZBM2 battery is a unique energy storage system that redefines your understanding of how a battery works. This scalable 10 kilowatt-hour (kWh) zinc-bromine flow battery delivers 100 per cent depth of discharge each day for a warranted 10 years – without causing any damage to the battery.

High performance. At high temperatures

The ZBM2 performs flawlessly in hot climatic conditions without external cooling. Unlike legacy battery chemistries, the performance, safety and operational lifetime of the ZBM2 zinc-bromine flow battery is unaffected by ambient temperatures as hot as 50°C (122°F).

10 kWh capacity. From Day One to Year 10

The ZBM2 delivers 10 kWh of sustained energy storage every day, backed by Redflow’s 10-year warranty. ZBM2 zinc-bromine flow batteries provide 100 per cent of their stored energy, with no loss of storage capacity – for a decade!

Standby for years. Start in seconds

The ZBM2 zinc-bromine flow battery can be stored at any state of charge – from full to empty – for weeks, months or even years. When you need power, the ZBM2 starts within 30 seconds, ready to deliver 100 per cent of its stored energy.

Scalable storage. From one to dozens

The ZBM2 zinc-bromine flow battery is designed to work on its own and can also scale to work as part of a much larger energy storage system, with as many batteries as you require.  ZBM2s are easy to deploy in scalable parallel clusters for high availability, high scale deployments at the largest sites.

Internet-ready. For easy remote access

The ZBM2 battery management system (BMS) captures performance data in real-time to enable 24/7 remote monitoring. Monitor and manage your ZBM2 batteries from your computer or mobile phone, using easy web-based notifications and controls.

Environment-friendly battery. Fully recyclable

The ZBM2 zinc-bromine flow battery is made from easily recycled or reused components. At its end of life, the battery’s zinc bromide electrolyte solution can be purified and used for new batteries.

Safe energy storage. Wherever you need it

ZBM2s are intrinsically safe devices, even when used in the most demanding locations. The temperature-tolerant zinc-bromine flow battery contains an inherently non-flammable electrolyte solution, with a design that means there’s no chance of ‘thermal runaway’.

Sustained storage. 10-year warranty

Redflow’s ZBM2 zinc-bromine flow battery delivers 10 kWh of energy storage, with 100 per cent depth of discharge, on a daily basis for a warranted battery lifetime of 10 years or 36,500 kWh energy throughput – whichever comes first.

Simple. One-step charging

Using 100 per cent of its 10 kWh energy storage capacity, Redflow’s ZBM2 zinc-bromine flow battery delivers a constant power supply, due to a flat voltage curve and simple one-stage charge profile.

Redflow. Redefines the battery

Redflow’s zinc-bromine flow battery redefines your understanding of how a battery works. With 100 per cent depth of discharge daily, the ZBM2 delivers a sustained 10kWh of energy storage capacity throughout its operating life.

Demonstration Trial Partners

Redflow has installed electricity storage system with end users, such as utilities and research organisations, for demonstration and trial purposes.

Ergon Energy Corporation

Ergon Energy

Ergon Energy is the Queensland Government-owned electricity distributor to regional Queensland, with an asset base of $8 billion and more than 650,000 residential and business customers.

RedFlow supplied 30 ZBM systems for installation and integration within the Ergon Energy electricity supply network, as part of the Australian Government’s Advanced Electricity Storage Technologies (AEST) program. The systems were used for managing peak electricity demand within three locations in Ergon Energy’s rural network and were remotely monitored by both RedFlow and Ergon Energy.

Ausgrid and the Australian Government

AusGrid

Ausgrid is a major utility in New South Wales Australia.  In conjunction with the Australian Government’s Smart Grid, Smart City trial, Redflow installed sixty R510 residential energy storage units in Newcastle and the Hunter Valley as part of the Australian Government’s Smart Grid, Smart City project.  Redflow’s involvement with this part of the project extended from late 2011 to mid-2013.

Another R510 was also installed as part of the Newington Smart Home sub-project.  Redflow began its involvement with this trial in 2010 with a lead-acid energy storage system, after which the system was upgraded to an R510 in late 2011 before ending its time at the Smart Home in mid-2013.

Please see the Smart Grid, Smart Cities R510 Case Study for more information regarding Redflow’s experience with Australian utility, Ausgrid, of the design, installation and operation of 61 R510 electricity storage systems in New South Wales, Australia. Redflow’s Whitepaper also provides an overview of key results and lessons learnt from the project.
