Canberra house models hybrid grid with Redflow

  • Location: Queanbeyan, New South Wales
  • Storage: ZCell 10 kWh zinc-bromine flow battery and LG 10 kWh lithium-ion battery
  • Inverters: Selectronic SP Pro 482 inverter and SolarEdge SE7300 inverter

Renewable energy advocate Jeff Knowles has successfully deployed a hybrid energy storage system, including a Redflow ZCell zinc-bromine flow battery and an LG lithium-ion battery at his home in the Queanbeyan suburb of Jerrabomberra, near Canberra. By using a SwitchDin droplet to orchestrate the respective benefits of these two very different battery chemistries, Jeff’s system provides a model for the hybrid energy storage network that he expects to develop in Australia during coming decades.

Darling Building beats energy shortfall with Redflow

  • Location: Adelaide, South Australia
  • Storage: Six x ZBM2s (60 kilowatt-hours of energy storage)
  • Inverter: Three-x Selectronic SP Pro 7.5 kilowatt (kW) inverters, delivering three-phase power.

Award-winning architecture firm Williams Burton Leopardi has deployed a scalable energy storage system based on Redflow’s ZBM2 zinc-bromine flow batteries to guarantee energy supply for its newly renovated Darling Building in central Adelaide. With the local electricity grid incapable of supplying the building’s peak power needs during summer and facing hundreds of thousands of dollars in extra costs to use natural gas, Williams Burton Leopardi has successfully deployed six ZBM2 batteries to store off-peak power and feed it into the building when required.

ZCell storage system cuts home power bill by 80%

  • Location: College Park, South Australia
  • Storage: 2 x Redflow ZCell zinc-bromine flow batteries, with 20 killowatt-hours (kWh) storage
  • Inverters: 2 x Victron MultiGrid 48/3000/35-50 battery inverter-chargers

South Australian John Altree-Williams has seen the summer quarter power costs for his Adelaide house plunge by 80 per cent from the previous summer after installing a Redflow-based energy storage system. As well as reducing electricity costs and improving energy independence by guaranteeing power supply during any grid blackouts, ZCell offers an Internet-enabled Battery Management System that allows Mr Altree-Williams to monitor closely his home’s energy usage patterns, enabling him to ensure it operates at peak efficiency so he can automate the system in future.

ZCell eliminates power costs for holiday house

  • Location: Mannum, South Australia
  • Storage: One ZCell zinc-bromine flow battery, storing 10 kilowatt-hours (kWh) of energy
  • Inverters: Three Fronius solar inverters and one Victron MultiGrid battery inverter

After Scott Hicks bought a holiday house at Mannum, on the Murray River in South Australia, he discovered that it came with huge power bills. The first summer power bill was $1700. Since deploying solar panels and a ZCell battery from Redflow, Mr Hicks has seen his electricity bills go into credit, despite being on a modest feed-in tariff. The ZCell battery also guarantees power supply for the house – which was previously disrupted by a pesky flock of white cockatoos chewing on the incoming powerlines.

Mossel Bay goes carbon neutral with Redflow

  • Location: Mossel Bay, Southern Cape, South Africa
  • Storage: Four ZBM2 zinc-bromine flow batteries, holding 40 kilowatt-hours (kWh) of energy
  • Inverters: Three Victron Quattro 48/10000 battery inverters and seven Victron MPPT solar inverters

Mossel Bay Municipality provides local government and electricity services to the South African city of Mossel Bay. Since deploying four Redflow ZBM2 batteries to support two buildings that house its Technical Services Department, the municipality has seen the facility become a net exporter of energy to the electricity grid, as the Redflow batteries intelligently store and supply energy generated by 114 solar panels on the roof. This has effectively made these two buildings carbon neutral and provided a model for how this energy storage technology can be used elsewhere in the community.

Queensland home sets Redflow residential record

  • Location: Near Wallumbilla, 40km east of Roma, Queensland
  • Storage: 6 x 10 kWh ZCell batteries www.zcell.com
  • Inverters: 2 x Victron Quattro 48/10000/140-100/100 inverter/chargers

When Scott and Breeann Bates built a new house on their Queensland cattle and grain property near Wallumbilla, they chose a ZCell-based energy storage system to give them independence from the power grid and freedom from having to pay electricity bills. Their six-battery system – the 60 kilowatt-hour energy storage system is Redflow’s largest ZCell residential deployment in Australia – ensures complete off-grid operation for their home, which is 2.7 kilometres from mains power.

Victorian couple live off-grid dream with Redflow

  • Location: Glenlyon, Victoria
  • Storage: 2 x ZCells, with 20 kilowatt-hours (kWh) storage capacity www.zcell.com
  • Inverter: Victron MultiPlus 48/5000/70 battery inverter/charger

Sound engineer Adrian Shand and his partner live in an old central Victorian stone cottage that is completely off the grid. Using two ZCell zinc-bromine flow batteries, powered by 21 PV solar panels, the Redflow-based energy storage system allows the couple to maintain a “city lifestyle” in the country, without “calorie counting” their energy use. The ZCells, which store a total of 20 kilowatt-hours (kWh) of energy, can charge fully in just four hours on a sunny day. ZCells also deliver consistently clean power that does not interfere with Adrian’s musical equipment. Continue reading “Victorian couple live off-grid dream with Redflow”

Bosco beats power cuts with Redflow batteries

  • Location: Johannesburg, South Africa
  • ZBM2 installation partner: Specialized Solar Systems http://www.specializedsolarsystems.co.za/
  • Storage: 14 x Redflow ZBM2 zinc-bromine flow batteries (total storage capacity of 140 kWh)

South Africa’s largest manufacturer of printed circuits, Bosco Printed Circuits, has eliminated twice a week power cuts that had disrupted production, delayed deliveries and cost more than 100,000 rand a year by deploying Redflow ZBM2 zinc-bromine batteries. Bosco has also reduced its electricity costs by minimising grid use during peak demand periods in the morning and evening – when charges increase by 300-400 per cent – by running the production line on solar-generated energy and off-peak power stored in its 14 ZBM2 batteries.
