Noble fires up ZCell for bushfire defences

  • Customer: Alan Noble
  • Location: Near Willunga, 47km south of Adelaide, South Australia
  • Storage: 2 x 10 kWh ZCell batteries www.zcell.com

Prominent Australian technology executive Alan Noble required an all-season, highly reliable energy supply at his family-owned property near the South Australian town of Willunga, to guarantee water pumps would work on high fire-risk days in summer. Faced with a very high price to extend mains power across the hilly 100-hectare block, plus the expense of ongoing electricity bills, Mr Noble decided to deploy a more cost-effective off-grid energy storage solution based on two ZCell batteries that can store 20 kilowatt hours (kWh) of energy – eliminating power bills for the property entirely.

Hackett house powers through SA blackout

  • Customer: Simon Hackett
  • Location: Adelaide, South Australia
  • Storage: 2 x Redflow ZBM2 batteries

Simon Hackett is a man who likes to walk the walk as well as talk the talk, so the Redflow CEO was an early adopter of the Redflow-designed zinc-bromine flow battery that is at the heart of the ZCell residential energy storage system. At his eastern Adelaide home, Mr Hackett installed two Redflow batteries in early 2016, replacing a pair of ageing lead-acid batteries. As well as slashing energy consumption in his home, Mr Hackett saw the batteries power his household through a state-wide grid blackout in September that year without his family even noticing the power outage.

Conservation SA showcases ZCell

  • Customer: Conservation Council of SA (Conservation SA)
  • Location: 111 Franklin Street, Adelaide, South Australia
  • Storage: 2 x 10 kWh ZCell batteries

As the state’s peak environmental organisation, the Conservation Council of South Australia (Conservation SA) seeks to lead by example. As well as installing 13 kilowatts (kW) of photovoltaic solar panels on the roof of its central Adelaide office to reduce its carbon emissions and power costs, Conservation SA deployed two 10 kilowatt-hours (kWh) ZCell batteries from Redflow to extend those benefits and to provide a backup energy supply during power blackouts.  Continue reading “Conservation SA showcases ZCell” →

Redflow telco BTS case study from Latin America

This case study discusses the successful installation of Redflow batteries into a telecommunications base transceiver site (BTS). The BTS is located in a remote location in Latin America, accessible via rocky road and difficult terrain. The key site issue was an intermittent grid, meaning constant site downtime equated to a loss of average revenue per user (ARPU), as well as an unreliable service for the customers of the mobile network operator (MNO).

Strengthening Telecommunications Networks in the Developing World

Redflow recognises that telecommunications tower sites using DC power (either weak grid or off-grid) represent a major potential market for its ZBM2 zinc-bromine flow batteries:

  • Millions of telco sites globally – including but not limited to communications network tower sites
  • Asia alone has more than 2.7 million telecommunications tower sites
  • Large proportion, especially in developing countries, are off-grid or in weak-grid environments, and
  • An entry-level telecommunications site deployment typically uses 2-4 ZBMs to replace a lead-acid battery system.

Whitepaper: Redflow ZBM2 and telecommunications integration

This article reports about the successful demonstration of the Redflow’s unique zinc-bromine flow battery integrated into a standard telecommunication (Telco) DC system at -48V. The ZBM2 energy storage systems, installed directly on the DC bus, can replace standard lead-acid batteries and support the load when the power from the grid or from a diesel generator (DG) is not available. In this specific study, the ZBMs are used to integrate renewable sources (PV) with an existing DG allowing the coexistence of multiple sources, absorbing the load and PV fluctuations and most importantly reducing the DG run time. To learn more, download Redflow’s telco application White Paper

Report: The University of Queensland (Australia)

BRISBANE, QLD, AUSTRALIA, 2012: The University of Queensland (UQ) has installed the largest rooftop-mounted solar PV array in Australia (1.2 MW), located on three of its buildings at its flagship St Lucia campus in Brisbane, Australia.

In mid-2012, Redflow has installed its M90 energy storage system (90kW / 240kWh) alongside one section of the UQ solar field, marking our entry into the megawatt-scale class of energy storage systems.  It was designed to store solar power generated from a 390 kW section of UQ’s PV array in the daytime, and feed it back into the local network at times when it is needed most.
