PROJECT 01

Residential Off Grid Solar & Battery System

Sunshine Coast Hinterland

The Challenge

This client was building a brand new home in the Sunshine Coast hinterland and came to us with a clear goal — complete energy independence. No power bill. No reliance on the grid. Just clean, reliable energy to run a full family home including two ducted air conditioning systems, water heating, and all appliances.

The Solution

After consulting with the client and assessing their energy requirements, we designed and installed a comprehensive off grid solar and battery system built around top tier equipment to ensure long term reliability and performance.

System Includes

80 x 475W Jinko Solar panels, 38kW solar generation, 30kW Deye inverter, 61kWh battery storage, Hyundai auto-start generator and weatherproof IP rated enclosure.

The Result

The client now enjoys complete energy independence with no electricity bill, no grid connection, and total peace of mind.

PROJECT 02

Remote Off Grid Solar Hybrid System

Northern Territory Cattle Station

The Challenge

This remote cattle station was running an ageing diesel generator around the clock. Fuel, transport and maintenance costs were continually increasing.

The Solution

Detailed energy monitoring was completed before designing a solar hybrid solution tailored to the site's actual energy demands.

System Includes

160 x 450W panels, 72kW solar generation, Fronius Tauro inverter, 160kWh battery storage, 100kVA generator and underground cabling.

The Result

Generator runtime reduced by 90%, dramatically lowering fuel costs and maintenance while improving reliability.

PROJECT 03

Off Grid Solar & Battery Upgrade

Residential Home, Fraser Island

The Challenge

An ageing lead acid battery bank had deteriorated significantly and could no longer provide reliable storage capacity.

The Solution

We upgraded the storage and inverter system with modern equipment while retaining the existing solar array and generator.

System Includes

28 x 510W JA Solar panels, Victron Quattro inverter chargers, 8 Pylontech lithium batteries and generator integration.

The Result

A modern, reliable off-grid system with improved storage, better performance and reduced generator reliance.
