We are Stand Alone Energy Specialists

Off-Grid Energy Australia is a nationally accredited designer, installer and supplier of Remote Area Power Systems and Grid Battery Backup Solutions.

We combine solar panels, wind turbines, fuel generators and battery storage technology to independently power a range of applications with dependable, clean and cost effective electricity.

We use SP PRO as it gives comptete control of your power.
Charge your batterys off the cheepest OFF Peak power,and /or Charge battreys off your solar.

Grid Feed and Grid Battery Backup in one unit

Add the versatility of energy storage to your Grid Connect solution using the SP PRO as a low voltage grid feeding inverter that puts you in control of your grid system.

Interactive Inverter Charger

This versatile inverter can also be configured to operate as an Interactive Inverter Charger with conveniently preset configurations for use in mobile or Off Grid power systems.

Multiple Applications

The SP PRO is suitable for Grid Connect and Off Grid applications for residential, commercial, industrial, marine and mobile situations.

Engineering Excellence

The SP PRO contains features not found in other inverters. With highly accurate thermal power management and high speed digital signal processing, the SP PRO sets new standards for reliability, power density and flexibility.

The SP PRO is AS4777 Approved

The SP PRO series is available in sizes ranging from 3 kW to 20 kW for a single phase system and 9 kW to 60 kW for the SP PRO in a three phase configuration. All SP PRO inverters are approved to AS4777 for grid connection in Australia
