After dropping a series of strong hints – including those given in interviews with PV Tech Storage – Enphase has confirmed that its AC battery will be launched in Australia first.
The US-headquartered microinverter and PV energy management specialist announced the news via its company blog yesterday. The blog quoted Nathan Dunn, managing director for Enphase Asia-Pacific, saying that Australia has “always been a strategic market” for Enphase. The blog gave an unspecified time frame for launch but said it would be during 2016, while an Enphase spokeswoman confirmed the news morning to PV Tech Storage.
Enphase has been in Australia since 2013 and claims now to be the dominant microinverter player in the country, referring to an estimated 8% market share reached during the first half of this year in the blog.
Tellingly, CEO Paul Nahi had said in the company’s most recent earnings call with analysts, for the second quarter of this year, that there was “palpable excitement” over the growing economic case for solar-plus-storage in Australia.

This was a topic Nahi had covered in an interview with PV Tech Storage in June, when he talked about the fact that although policy support for renewables was dropping in parts of Australia, with regional feed-in tariffs (FiTs) being phased out over the next few years, storage could add value to existing installations and continue to encourage deployment.
“…in Queensland you’re going to zero export. You can do solar all you want, but you can’t export to the grid. That’s obviously very different to net metering. You can’t send it on the grid, you get penalised if you do. In that case, you have to have storage,” Nahi said.
“If you have zero export and you’re generating during the day, you don’t have enough load, you’ve got to fill up the battery and then at night you discharge it… and zero export is how the Queensland utility is dealing with grid stabilisation.”
On the other hand, Nahi said, in New South Wales, there was a different but equally viable business case around storage and solar.
“You have a very dramatic reduction in the FiT that is coming, the FiT drops to about six cents yet power from the utility will be about 30 cents a kilowatt-hour, so that arbitrage opportunity between the two is where storage comes into play. Why would you send it back at six and buy it at 30 why don’t you just store it and then use it? That’s an obvious economic case.”
Favourable behind-the-meter economics
The desire on Enphase’s part to hit the Australia market sooner, rather than later, ties in with wider views of the economics of solar-plus-storage in the country. The strong potential of behind-the-meter storage in Australia has been talked about by a number of other commentators and analysts, for both economic and non-economic considerations.
ARENA, the Australian Renewable Energy Agency, put out a report on the state of global energy storage and how it relates back to the domestic situation in July. ‘Energy storage study: Funding and knowledge sharing priorities’, prepared by technical services company AECOM, pinpointed behind-the-meter storage as being the market with the most potential in the country.
However, as Sam Wilkinson of research firm IHS and AECOM’s Craig Chambers pointed out in PV Tech Storage’s coverage of that report, electricity prices vary by region, utility and time of day in Australia, making it tricky to draw general conclusions. Nonetheless, the favourable economics in certain regions and the relatively high uptake of residential rooftop solar across the country, as well as the beginning of trials to unlock more value from storage by aggregating a large number of customer-sited systems together, appears to make Australia a favoured destination for storage makers at present. Panasonic and local manufacturers are among the other interested parties prepared for competition with Enphase.
