As Australia’s energy costs soar, Melbourne-based company ZERO Living has launched five battery-powered houses with a breakthrough design that makes them more affordable to buy and live in, with zero energy bills and no blackouts.

Costing from $640,000 for a two-bedroom home, the fully engineered houses are in the western Melbourne suburb of Albion, where the median house price is more than $800,000. Fitted with Enphase microinverter-equipped solar panels and Tesla batteries, each house generates more than twice as much energy as it consumes. This effectively reduces its energy costs to zero, saving its owner an average of nearly $50,000 in energy costs over 20 years (in 2021 costs) *.

ZERO energy homes are designed from the roof down for space, comfort and low energy use, with high-quality energy-efficient materials, appliances and insulation. Each home is individually tailored to its building site, maximising its liveable space while reducing the building footprint and property cost.

ZERO Living founders Tom and Ingrid Graze have collaborated for the past three years with Swinburne University of Technology’s School of Engineering to develop smart energy monitoring systems that can help homeowners become even more energy-efficient.  Each home is wired to monitor major appliances in real-time, with Swinburne analysing the data and returning it to the homeowner or occupant via a ZERO smartphone app.

Within days of the Australian Federal election, Sydney-based Solaray Energy saw solar photovoltaic (PV) system inquiries double with one in two new customers ordering batteries with their solar panels.

After first-quarter sales cruelled by Omicron, summer floods and the impending election campaign, Solaray’s recent solar sales have rebounded to levels closer to the record demand of 2020 and 2021.

Solaray, a five-time Enphase installer of the year that has installed more than 75,000 Enphase microinverters in Australia, is active in the premium end of the NSW residential solar market.

Solaray director and co-founder Jonathan Fisk attributed the rebound in the solar market to the election delivering a pro-renewable energy parliament and surging energy prices. “In the second half of May, our inquiries jumped by close to 100 per cent,” he said.

MELBOURNE, Australia, June 6, 2022 — Enphase Energy, Inc. (NASDAQ: ENPH), a global energy technology company and the world's leading supplier of microinverter-based solar and battery systems, announced today that a growing number of Australian solar installers are now exclusively offering Enphase® products, as increased solar safety regulations and compliance standards come into effect across the country.

In May 2022, AS/NZS5033:2021, an update to installation and safety requirements for photovoltaic (PV) arrays, came into effect nationwide in Australia. The revised regulations aim to support solar installers in meeting compliance requirements and promoting consumer and electrical contractor safety. The standard details new compliance measures for direct current (DC) central (“string”) inverter-based solar systems, including restrictive cable runs, IEC 62930 compliant DC cable, and high visibility DC voltage and warning signs. In contrast, alternating current (AC) decentralized inverter-based solar systems operating at extra-low voltage, such as installations with Enphase microinverters, are exempt from most new regulations. As a result, some Australian solar installers are exclusively leveraging Enphase technology to help insulate their businesses and customers from electrical risk and future regulatory changes.

Wilf Johnston v1 H WEnphase Energy General Manager ANZ & Pacific Wilf Johnston Enphase Energy has called on Australia’s new Government to convene a renewable energy summit that can align national resources for a more coordinated drive to achieve carbon net-zero.

After Saturday’s Federal election elected a new parliament overwhelmingly committed to more aggressive action on climate change, Australia needs to harness all its resources to focus on accelerating the nation’s transition to a low-cost renewable energy economy.

Enphase Energy General Manager ANZ & Pacific Wilf Johnston said Australia could reap enormous economic benefits from getting all parties involved in the renewable energy sector into one room. “Bob Hawke did this successfully with the National Economic Summit in 1983,” he said.
