Independent Power - Athenaeum House

"I have spent quite a lot of time researching into how to approach our off-grid power system upgrade. I knew it wouldn’t be a straight-forward job as I really wanted to integrate it with our existing wind turbine and take advantage of the wind and sun complementing each other. I contacted quite a few companies and only Independent Power provided the level of professionalism I expected. They were not only very helpful and knowledgeable but at the same time they used their “know how” to optimise the design in such a way that it brought down the cost of the system significantly. This resulted in serious savings for us. I sincerely recommend Independent Power to anyone interested in installing a renewable energy system on their property. The Peace of mind having a reliable system is priceless". Chris Guy & James Cavanagh Residents, ( Waitomo

Independent Power - Off-grid Power Supply Motukiekie Island


  • Remote 30 hectare private island with no mains power available
  • Existing off-grid system had been out grown and was starting to fail
  • Batteries were at the end of service life with some failed cells.
  • 3 x solar arrays of various ages
  • Numerous generator failures


  • Removal of old arrays and installation of new PV arrays.
  • Installation of new Outback FPA3, 48volt 9kW system
  • Install new Juice Lithium battery bank
  • Install new generator
  • General tidy up of existing AC distribution board and cabling


  • New fully compliant system
  • System reliability
  • Increased capacity of both storage and output
  • The upgraded PV array with greater generation was well suited to the high charging current of the lithium batteries
  • Remote monitoring now available


“When asked to upgrade the power system on a remote off grid island, the Outback products were an easy choice for this project as they offered proven reliability, and when coupled with the Outback OpticsRE remote monitoring feature, they are the obvious choice for a remote location.

The timing of the project meant we had the option of the new Outback FPA prewired system. We selected the FPA3. The installation was simple and quick, and knowing you are installing a fully compliant NZ system with the correct isolation and protection devices, was important to us, not to mention the time saved onsite.

The FPA system’s design allowed ample room for our incoming and outgoing cables and the option for future expansion should it be needed. From the property owners perspective, the system is very neat and the Mate 3 home screen offers the owner the information they want at a glance. Also, the intuitive function of the Mate3 allows for easy navigation should it be needed.”
