Australian Made Solar Inverters

We are currently assessing the viability of a new range of 5 kilowatt solar inverters designed for use with residential and industrial solar systems. The local market is dominated by manufacturers like SMA and there is a niche market for locally designed and supported inverters. With the advent of solar battery storage technology – pioneered by Panasonic (in part), and the government acknowledgement that grid intermitency is likely to be an ongoing problem, we are looking to design battery storage connectivity into any inverter designs.

Solar Inverter Specifications

Our initial design concepts are built around the following requirements and specifications:

  1. Greater than 97 percent efficiency
  2. Connectivity that includes RS 232 and USB ports
  3. Wide input voltage operating range
  4. Minimum IP65 rating (possibly greater, given Australian summer temperatures)
  5. Both field and remote upgrade options available
  6. Minimum 10 year full warranty with Australian service and support
  7. 100 percent transformerless design
  8. Use of low RDs on mosfet ouput switching (PWM)

In house design in partnership with John Grainger, a long term advocate for solar technology in South Australia.

Market Outlook For Solar Power In Australia

We are confident that the long term future for residential p.v. systems in Australia remains strong. With fewer than 12 percent of homes already having solar panels installed, the outlook for energy prices to continue to increase in years to come and government incentives likely to remain in the near term, the outlook for the market is positive.

Locally Produced Inverters

Manufacturing locally designed electronics in Australia remains viable. Whilst the outflow of manufacturing in the electronics sector from Australia to China was witnessed between 1990 and 2010, there has been a steady reversal of this trend in the last 5 years. With local contract manufacturers investing in surface mount ‘pick and place’ technology, the cost of electronic assembly in Australia is now estimated to be only 10 to 15 percent above that of China based manufacturing. Manufacturing locally means greater market ‘agility’ and the ability to be able to change designs and manufacture in a matter of days rather than weeks.

We will update readers on this new project over the coming weeks.
