Carinya Cottages –
Luxury Off Grid Escape

Faced with the cost of a grid infrastructure upgrade, new transformer and private power poles – they decided that going off grid was a much more reliable and cost-effective option.

Carinya Cottages – Luxury Off Grid Escape

Objective:

Power for 6 luxury accommodation villas, and homestead.

Faced with the cost of a grid infrastructure upgrade, including a new transformer and private power poles, which would then only provide an unreliable power – the customer decided that going off grid was a much more reliable and cost-effective option. With the added bonus that he didn’t have to deal with power utilities or retailers by going off the grid.

This whole property is off-grid in every sense. Including huge rainwater storage, fire-fighting facilities, and reed-bed sewage wastewater filtration system.

Site Considerations:

Off-grid system installation in shed, with solar arrays installed on the shed roof as well as ground mounted. AC sub-mains electrical connection from the system switchboard to the house/cabin switchboard will be completed after the off-grid system installation as the cabins were yet to be built.

Load Analysis:

Average summer demand: 78.35kWh
Average winter demand: 85.76kWh
Demand surge: 34.14kW

System Design:

  • Selectronic SP Pro SPLC1202 20kW Inverter Charger
  • BAE VRLA Sealed Gel batteries (248kWh)
  • Trina Solar 300W solar modules (32.4kW)
  • 3 x Fronius Primo 8.2 Solar Inverters
  • Roof and ground mounted solar framing
