3 kW Off Grid Solar – Darling Downs

Date: February 28, 2016

This 3 kW Off Grid Solar system located in the Darling Downs, Queensland generates sufficient electricity for a rural property and has been future proofed with Midnite solar charge controller which can be upgraded by another 2 kW.

The Outback Off Grid solar inverter automatically detects when the generator is present and switches the load from the inverters to generator, whilst recharging the batteries. The Outback inverter/charger can deliver a massive 5750 Watts of surge power to start up water pumps, fridges, freezers and power tools.

The Midnite Solar charge controller can deliver 88 Amps continuous, has easy to use display and records information in and out of the whole system. The owners can increase the size of this system by another 2 kW. Like any Off Grid solar design the Midnite Solar charge controller was selected for future proofing.

The Exide Energystore deep cycle solar batteries supply 5 days of electrical energy, meaning that if the advent of overcast weather the owners still have continuous and reliable power. Once the sun shines again, the solar array can fully recharge the battery bank in less 5 hours.

This Off Grid Solar system supplies all essential power to a household including 1 fridge/freezer, lighting, kitchen appliances, washing machine, computers, entertainment, power tools, water pump etc. It was a solution of getting reliable electricity to a site where the main electricity was more than 1 kilometre.
