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.
