Edson Piggery

The property SWER Network connection for Edson Piggery was insufficient for their needs – both now and for any future expansion. This made off grid an attractive option.

The off grid system would need to power the Piggery feed lots, farrowing sheds, staff facilities, and growing pens.

Edson Piggery secured funding through the Coles Nurture Fund, for the installation of the power system – as well as other sustainability enhancements at the facility.

System Design

Ground mounted solar was deemed the most appropriate for the site, and land was prepared for the installation of the arrays.

A new shed was custom-fitted on site to house the battery and inverter equipment.

  • 296 x Trina 310W Modules (91.76kW)
  • Ground Mounted Frames at 30° pitch
  • 2 x SelectSun 40k Solar Inverter
  • 3 x Selectronic SPPro Inv/Ch
  • 120 x BAE VRLA Batteries (535kWh)

Project Outcome

Stringent project management enabled a streamlined installation process, despite unavoidable product supply delays that occured.

The off grid solution provided will generate enough energy to power the entire farm, slashing long-term power costs and cutting emissions.

A seperate grid connected solar system was also installed on the adjoining home.

Port Authority Off-Grid Security & Communications

Reliable and stable power was required for critical surveillance & access control equipment – including site access gates and turnstiles – over two remote Pilbara port sites, which export vast quantities of high quality minerals.

Mains power wasn’t readily available, and powering solely via diesel generators was cost prohibitive and a potential power quality risk to sensitive equipment.

Reliability, clean energy, and the ability to achieve complete redundancy in the event of extreme weather events was critical for on-going operations.

System Design

Given the sites remoteness, which also lies within a wind region D classification, specific system design and fabrication was required to meet all relevant engineering principles.

Custom equipment housing included HVAC to provide a stable environment for system operation, ensuring longevity as constant high temperatures were a concern.

  • 162 x REC 320W Modules (51.84kW)
  • Transverse Strip Ground Mount Array
  • Selectronic SelectSun 40k PV Inverter
  • 45kW 1-3P Selectronic Inv/Ch Output
  • 455kWh L-ion BYD Battery Storage
  • 2 x IP55 Customised Enclosures

Project Outcome

At the time of installation, this is the largest BYD B-Box Pro installation in Australia

Off site prefabrication and comprehensive system testing was completed before deployment ensuring successful project fulfilment. This approach also reduced freight costs and on site operational disturbance.

15.8 tonne of CO2 will be saved for each year of system operation.

The installation provides 100% self sufficiency to the site, ensuring full operations can continue without the intervention of personnel.

Manufacturer Reduces Energy Costs

Solar for manufacturing business


A well established manufacturing facility with high power usage was seeking to reduce their ongoing power costs. An independent financial assessment was completed to confirm a solar installation would be the most viable investment.

The installation needed to be completed at a time when production lines would not to be effected, and equipment location was of importance to maintain the existing work areas. Plant operators required instantaneous visuals for generation, consumption, and logging historical data for reviews.

System Design

The system was tailored to maximise self consumption from the highest yielding roof areas, with a degree of insulation benefits throughout summer further adding to property efficiencies.

A different electricity retailer was selected to offer surplus solar feed in credits for non-operational periods.

  • 560 x Trina 270W Modules (151.2kW)
  • 4 x Fronius ECO 25.0-3 Solar Inverters
  • 1 x Fronius Symo 20.0-3 Solar Inverters
  • IntelliPro Grid Protection Unit
  • Fronius LGC Compliant Monitoring
  • Combiner Box and BOS
  • Custom Inverter Wall Fitout

Project Outcome

The system is predicted to save almost $370,000 in ten years – and pay for itself in under 5yrs. The installation was thoughtfully planned so production and operation were unaffected.

A detailed monitoring platform was included so the plant operators have an instantaneous visual on generation and consumption, and saved historical data for ongoing reviews.

Huntlee Off-Grid Development

off-grid housing

“If it can be done for a house, why can’t it be done for a town?” was the solar powered thought running through the mind of Off-Grid Energy Australia’s NSW manager, Damien Griffith as a standalone power system was installed on his Hunter Valley farm in 2009.

Huntlee is a 7500 home development, with a planned large town centre and a number of neighbourhood village centres, servicing an eventual population of 25,000 people. It is a development that closely considers the creation of a new social fabric as the new community is born.

The beginnings of the “autonomous town” project began in earnest in early 2012 after LWP property NSW General Manager Ian Wilks, agreed to incubate and fund the challenging journey Mr Griffith was proposing to decentralise utilities and take the town off grid. This journey saw the creation of the Huntlee Energy and Technology Alliance (HETA) where a number of experts in their respective fields met regularly to collaborate on the vision of decentralised utility provision, with a major focus on energy.

HETA Members:
LWP Property Group (Developer), Worley Parsons (Project Manager), Lume Energy (Project Concept & HETA Chair), Off-Grid Energy (Solar PV & Storage), Simons Green Energy (Co-gen & Thermal), Flow Systems (Water), Opticomm (Communications), Jemena (Gas), Frank Klostermann (Waste to Energy).

System Design: 

Off-Grid Energy, together with co-gen and thermal network experts Simon’s Green Energy found that the levelised cost of energy per lot is substantially lower for the microgrid than if the development were to connect to the national grid.

The initial design found the optimal balance between sufficient baseload power, and maximum renewable content.

Load control at individual premises and demand side management functionality will be included in Huntlee house design. Electric vehicle (EV) charging at the premise has included in the utility design, and the potential for time-of-use EV charging incentives has been identified.

Project Development:

$442,000 in ARENA funding will allow global asset manager, Brookfield Energy, to complete a $1.1 million dollar further study into reglatory requirements for microgrid implementation in Australia.

Microgrid System on Luxury Farm Estate

containerised batteries


The system was required to provide the equivalent reliability, capacity (kW), and energy (kWh) availability of the grid, whilst maintaining an economic advantage.

The buildings on the property which required power included horse stables, heated swimming pool, bore pump, workshop, 2x guesthouses, painters studio, and of course the main residence.

Site Considerations:

No consistent view of the solar array or equipment building, hear no noise from the backup generator at the main living areas of the property, and not disturb the resident wombats.

System Design: 

The system design provides an average yearly solar contribution of 117%, peak delivery capacity of 300A per phase, with a 250kVA super silenced generator backup. AC coupled configuration allows the inverter/charger, solar inverters and generator to ‘layer’ and provide high peak power capacity.

  • 264 x Trina 260W Modules (68kW)
  • Ground mounted frames at 30° pitch
  • 3 x SMA STP20000TL Solar Inverters
  • 18 x SMA SI8.0 Inv/Ch (144kW)
  • 144 x BAE PVV1800 VRLA Batteries
  • 250kVA FG Wilson diesel generator
  • SMA Multicluster 36 Box switchboard
  • SMA Webbox Monitoring system

Project Outcome:

Off site assembly of the containerised equipment housing allowed for cost reduction, quality control, and passive cooling techniques to be included. Significant ground-works removed system visibility from the main residence. Generator sound attenuation achieved 65dba at 7m distance, and efforts were made to ensure a high-quality aesthetic.

“Communication was excellent, the team was professional and had a great attention-to-detail. They made sure every step of the process was delivered on time, and without compromise.”
