One Off-Grid Property, Two Off-Grid Homes

Robert & Sue had their original system installed with us in March 2015, and when they decided to build another home on the same property they contacted us to provide a new off-grid system to power it.

The old system would be left in place on the shed to continue to power the original Beetaloo Grove Cottage – now available for hire as a Bed and Breakfast here: beetaloogrove.com.au/accommodation

Original installation details:

Outback VFX3048 with Flexmax MPPT regulator, VRLA batteries, and LG solar panels. Original system was designed for 1.54kWh summer, 1.4kWh winter, with a design surge of 1.8kW. The customer had supplied their own batteries (ex Telstra batteries, Yuasa VRLA).

• Selectronic SPMC481 inverter/charger
• Powerplus ECO lithium-ion batteries (12kWh)
• 4 Module battery cabinet
• Trina Solar modules (5.6kW)
• Fronius Primo 4kW solar inverter

Project Outcome:

It’s amazing how far technology had developed in the seven years between installations on this property. The progress of lithium-ion chemistry for home batteries meant that Robert & Sue could install battery storage for six times the amount of usage, in a quarter of the physical space.
