Redflow batteries and Victron inverters

Redflow’s ZBM2 and ZCell zinc-bromine flow batteries have worked with Victron Energy’s MultiGrid 48/3000 battery inverter since it was approved to connect to the Australian electricity grid in 2017.

Redflow batteries also work with Victron’s popular MultiPlus inverter range, including the MultiPlus-II, which was launched earlier this year. The MultiGrid 48/3000 is a version of the MultiPlus 48/3000 inverter enhanced to meet the AS/NZS4777.2:2015 standard for grid connection of energy systems via battery inverters.

The Victron MultiGrid 48/3000 inverter is listed on the Clean Energy Council website at http://www.solaraccreditation.com.au/products/inverters/approved-inverters.html#searchResults.

ASX-listed Redflow (ASX: RFX) produces Australia’s unique ZBM2 and ZCell zinc-bromine flow batteries, which offer significant advantages over legacy lead-acid and lithium-based batteries including 100 per cent daily depth of discharge, sustained energy storage capacity and tolerance of warm ambient temperatures as hot as 50 degrees Celsius.

Redflow System Integration Architect Simon Hackett said the Victron MultiGrid 48/3000 inverter for grid-connected battery systems was good news for consumers. “Victron inverters are easy to configure, they work beautifully with our ZBM2 and ZCell batteries and they are competitively priced,” he said.

“Victron inverters have proved popular with Redflow customers who install off-grid energy storage systems, so AS4777.2 approval makes these inverters available to a much larger market. Victron inverters integrate easily with single-battery ZCell systems and are fully compatible with all major brands of AC solar inverters. This certification builds on the strength of the Victron product line in off-grid scenarios where it has a long pedigree in Australia.”

Victron inverters are successfully integrated with many Redflow battery-based energy storage systems including:

A six-ZCell deployment in central Queensland

A major printed circuit board factory in Johannesburg, South Africa 

A two-level commercial building in the Adelaide CBD.

Founded in The Netherlands in 1975, Victron Energy first built a strong international reputation for its automotive and marine battery inverters. The privately owned company then entered the solar PV market, leveraging its experience to build robust and reliable off-grid battery inverters which are now certified for use with grid-connected hybrid energy storage systems.

BMS – Battery Management System



Redflow's Battery Management System (BMS) creates 'smart batteries'

The key to Redflow’s “smart batteries” is the Redflow Battery Management System (BMS) which:

  • Simplifies Redflow battery deployment and configuration
  • Remotely monitors and manages Redflow batteries
  • Ensures Redflow batteries always contain the latest software updates.

Control via a web browser

The BMS is a small DIN Rail-mounted device that connects one or more Redflow batteries with the inverter-charger that your installer provides for your energy storage system. The BMS lets you set up, monitor, and control your Redflow battery using a web browser. It also provides battery status and operational information to your AC inverter-charger so that it can optimise its use of the electrical energy stored in your battery.

Embedded know-how

The Redflow BMS is a device that embeds more than a decade of know-how in the efficient and effective real-world operation of Redflow’s unique zinc-bromine flow battery. The BMS enables rapid on-site commissioning using just a smartphone or laptop. The BMS also provides secure remote access via any Internet path, using its built-in Ethernet or WiFi ports, to the Redflow battery management cloud service.

Cloud-enabled remote monitoring and management

The Redflow BMS leverages modern cloud infrastructure to enable easy and effective remote access to installations of Redflow’s zinc-bromine flow batteries. The BMS supports remote system performance monitoring, alarm monitoring, diagnostics, performance optimisation and software updates. The BMS also gives integrators a “fleet-wide” view of their customer sites and enables Redflow to cooperatively optimise sites with integrators.

Real-time display and system control

The Redflow BMS ‘knows’ how to efficiently run ZBM2 and ZCell batteries including:

  • Seamlessly managing battery maintenance cycles
  • Optimising energy efficiency by sequencing batteries in charge and discharge to suit the application requirements
  • Real-time status display and system control
  • Continuous logging performance data to the secure Redflow cloud, and
  • Remote battery fault detection and management.

Industry standard

The Redflow BMS uses industry-standard protocols to interface ZCell or ZBM2 clusters to energy storage systems. The primary protocols supported for energy system interfaces are CANBus BMS protocols, MODBUS-TCP, and URL-based data retrieval using JSON or plain text.

Interfaces

  • Isolated Power Supply input (9-65V DC)
  • Ethernet and WiFi Internet access ports
  • Opto-Isolated CANBus port for energy system interfacing
  • RS485 MODBUS port for ZCell/ZBM2 connection
  • Dry-contact relay for external device control using built-in event-based rules engine
  • Also supports external device control via MODBUS-TCP write commands and using USB-attached relays, and
  • USB ports for future expansion.

Redflow demos ZBM2 benefits at TowerXChange South Africa

Redflow this week promotes its ZBM2 zinc-bromine flow batteries for use in the booming telecommunications tower market at the TowerXChange event in South Africa this week.

TowerXchange is an open community for thought leaders in the emerging market towers industry, bringing together mobile network operators (MNOs), tower companies, investors, equipment and service providers to share best practices in passive and active infrastructure management, opex reduction, and to accelerate infrastructure sharing.

Redflow has a stand at the TowerXchange Meetup for Africa and the Middle East, which is running at the Sandton Convention Centre, Johannesburg, from October 3-4.

Redflow’s presence at TowerXChange aligns with the company’s focus, announced earlier this year, to insert its long-lived zinc-bromine flow batteries into the lead-acid refresh cycle for telco towers, a replacement process that typically occurs every 18-36 months in warm and tropical climates.

Telecommunications

Redflow powers telecoms in the most demanding locations.

Redflow’s ZBM2 zinc-bromine flow batteries provide energy for remotely-located telecommunications infrastructure internationally, including Australia, New Zealand, Indonesia, the Philippines, Thailand, India, Latin America and elsewhere. Redflow’s energy storage solutions equip telecom providers to ensure the off-grid or backup power supply requirements for remotely located telecommunication towers, effectively solving the problems caused by unstable grids, blackouts and intermittent renewable energy.

Soaring global use of mobile phones has led to estimates of 2.5 billion smartphones and four million telecommunication towers by 2018. The strongest growth in telecom tower deployment is in developing nations in Africa, Asia and the Indian subcontinent, where wireless telephony and Internet access have leapfrogged wired telco infrastructure, often in areas with unstable or no grid access.

Telecommunications providers in these areas face significant supply issues, including intermittent power and supply outages that can last for hours, days and even weeks. Even in developed nations, telcos need to ensure failsafe energy supplies to their Base Transceiver Sites (BTS) to meet customer expectations of uninterrupted access to mobile phone and data coverage.

Redflow’s 48-volt DC ZBM2 zinc-bromine flow batteries solve many of the problems that impact telecommunications providers, including the ability to operate in warm and dusty conditions without active cooling; long-term storage at any state of charge, from empty to full, without damaging the battery; and construction materials with little resale value, making them less attractive to thieves. The benefits of Redflow zinc-bromine flow batteries follow:

  • ZBM2 protects telecom coverage from grid outages and intermittent power supplies
  • ZBM2 stores solar energy until it’s needed, eliminating the intermittency of renewable power
  • ZBM2 stores 10kWh of energy with no storage capacity loss over 10 years
  • ZBM2 batteries deliver 100% depth of discharge on a daily basis
  • ZBM2 has a warranty for 10 years or 36,500 kWh throughput, whichever comes first
  • ZBM2’s ‘virtual genset’ mode loses no power over time and starts in 30 seconds
  • ZBM2 works in temperatures as warm as 50 degrees C (122 degrees F) without active cooling
  • ZBM2’s inherently non-flammable electrolyte means it has low risk of thermal runaway
  • ZBM2 allows remote access or monitoring via the Internet to reduce the need for site visits
  • ZBM2’s unique design reduces the risk of theft
  • ZBM2 reduces operating expenses (OPEX) and diesel costs when used with a genset
  • ZBM2 directly replaces lead-acid batteries at existing BTS locations in a fraction of the space
  • ZBM2 can be stored at any state of charge – from empty to full – for months or years. Please contact Redflow for further details on this option.
