280kWh Redflow-based microgrid in Tasmania

Redflow CEO Simon Hackett has installed a 280kWh Redflow-based rural microgrid in Tasmania. The sheep farm will benefit greatly from the ZMB2 flow batteries – let’s take a look at the install and how it’s going to work.

The 280kWh Redflow-based rural microgrid is now live according to a press release on the Redflow website. Simon Hackett’s place, a sheep farm named the Vale, has seen install of 280kWh of  Redflow ZBM2 zinc-bromine flow batteries. We first wrote about this Redflow microgrid in 2019 – fantastic to see the Vale’s solar installation improve and upgrade along with solar panel technology.

The Vale (http://www.thevale.com.au), a working sheep farm with the largest private runway in Tasmania, is a 73-hectare property including a number of farm buildings and multiple houses.

The solar install uses a cluster of 12 x 15KVA Victron Quattro inverter/chargers and control systems that can deliver a peak energy output of 180KVA – it’s wired throughout the property to create the microgrid. The solar energy created by the ground-mounted 100kWp solar array is stored in 28 Redflow 10kWh ZBM2 zinc-bromine flow batteries, for a total storage capacity of 280 kWh. 

Hackett went on to discuss some of the specifics of his microgrid in Tasmania:

“The battery array makes extensive use of the Redflow Standby Power System (SPS) mode, allowing batteries to be fully charged during good solar weather days, and to then be ‘hibernated’ with zero self-discharge. During extended overcast periods, the SPS batteries are automatically activated to support site loads instead of using the grid. This unique strength of Redflow’s ZBM2 batteries allows the site to maximise both energy storage quantity and also energy storage efficiency.”

Hackett, who also works as Redflow’s Systems Integration Architect, said the system will completely eliminate grid electricity costs for the property. “The system also gives us energy resilience by automatically switching to off-grid mode during any grid power failures,” he said.

Redflow – ZBM2 Microgrid in Tasmania for Hackett

Redflow CEO Simon Hackett has shifted his Tasmanian sheep and cattle farm to a new power source – a 100kW ground mounted solar microgrid using 27 Redflow ZBM2 batteries. Nice to see the bosses eating their own dog food. Let’s take a look at the project and what their future plans are for it.

Hackett, the owner of Redflow,  will use an initial deployment of 27 ZBM2 batteries, storing as much as 270 kilowatt-hours (kWh) of energy, interfaced to a large fault-tolerant cluster of 12 x Victron Quattro 48/15000 inverter/chargers.

“The project, with an overall budget of around $1 million, will include the building of a new site-wide microgrid. This will use new underground power interconnects to link seven distinct buildings across the whole property,” Hackett said in a statement. He went on to discuss the existing situation at the sheep and cattle farm he owns:

“We already have a Tesla Model S at the property and we plan to progressively replace our existing fleet of diesel farm ATVs, utes, and tractors with electric versions as soon they become available,” he said.

“We read with interest earlier this year that Toyota is committed to making electric HiLux 4WD vehicles and we would love to take delivery of the first of those to reach Australian shores.

Hackett explained that the Microgrid has myriad future plans and will be scalable:

“We can and will add more renewable energy generation using solar and/or wind if required in the future. Even after the full replacement of diesel vehicles with electric ones, we expect the property to be a net exporter of electrical energy to the Tasmanian grid,” he said.

Lastly, Hackett is very optimistic (mind you, he’d want to be) about the installation – we’re very interested to see some figures on how much it saves:

“I am convinced, based on my deep experience with Redflow, that ZBM2 batteries at the core of this energy system can deliver the hardworking energy storage and longevity to make this investment pay off over the long term,” he said in comments made last week.
