SAJ Electric unveils HS5 EK series and celebrates partner momentum with Alex de Minaur in Brisbane

BRISBANE, Australia, Sept. 15, 2026 /PRNewswire/ -- On 14 September, SAJ hosted over 100 of Australia's leading solar and energy storage decision-makers at Pat Rafter Arena, Brisbane, for an evening with brand ambassador Alex de Minaur, a first look at the company's new HS5 EK70 and EK90 series of energy storage systems, and a celebration of its expanding Australian distribution network.

The invitation-only event brought together installers, distributors and industry representatives from across the country, days before de Minaur takes the court at the same venue for Australia's Davis Cup tie against Poland.

Alex de Minaur joins SAJ as brand ambassador

De Minaur, the Australian No. 1 men's singles player, is the face of SAJ's "Relentless Energy" campaign. The partnership pairs de Minaur's reputation for consistency, speed, accuracy and endurance with SAJ's reliable, long-life residential energy storage.

On the night, lucky guests had the opportunity to watch de Minaur train on the arena court, then play King of the Court against him before he joined SAJ leadership in the event space.

First look at the HS5 EK70 and EK90

The evening marked the Australian debut of the SAJ HS5 EK70, an all-in-one residential energy storage system that combines solar inverter, battery storage, backup power, energy management system, and EV charger in a single integrated unit. The EK70 supports whole-house backup (63A bypass), one-click diagnosis and automatic CT correction via the elekeeper app, reducing commissioning errors and time, while the Wireless-Pro Meter enables stable, long-range communication for fast, hassle-free installation. The EK70 carries a 10-year warranty rated at 10,000 battery cycles.

Safety features include full-coverage battery temperature sensors, cell insulation boards, an integrated aerosol fire suppression system and battery pressure relief valves. SAJ's AI Saving, AI Keeper, AI Edge and AI Designer functions manage charging, backup reserve, tariff optimisation and system design.

The EK70 will be available through SAJ's Australian distribution partners and is now CEC-approved. SAJ is the first brand in the industry to be listed under the new standard SA TS 5398.

SAJ also previewed the HS5 EK90, the next model in the series, which builds on the EK70 platform with AI-enabled AFCI, on-device edge AI, vehicle-to-grid and vehicle-to-home (V2G/V2H) capability (coming later), and a battery design certified to UL 9540A. The EK90 is rated at 12,000 battery cycles with a 15-year warranty and is expected to arrive in Australia later this year.

Powered by elekeeper 5.0

The HS5 EK series ships with elekeeper 5.0, SAJ's next-generation energy management platform, launched in Australia on 10 September. elekeeper 5.0 supports dynamic tariffs, negative pricing and smart scheduling, and connects with the VPP and dynamic-tariff platforms Australian households already use, including Amber, Evergen, GloBird Energy, Origin, POWSTON and Synergy.

Five AI capabilities cover the full system lifecycle. AI Designer handles PV layout, equipment matching and return-on-investment modelling for installers; AI Care lets installers verify wiring and scan battery health remotely and action fixes with a single click; AI Saving optimises energy use against forecast generation, household demand and electricity prices, and is already running across more than 10,000 residential and C&I sites worldwide; AI Edge keeps optimisation running locally if connectivity drops; and AI Keeper provides natural-language assistance for homeowners and energy professionals.

The elekeeper app is available now on the Apple App Store and Google Play and comes as standard with SAJ's latest generation of solar and storage products.

Leadership sets out Australian growth plans

SAJ's senior leadership attended the event, including Care Guan (Senior Director of APAC & MENA Region), Alan Li (AU Country Manager), and Vincent Dyer (Senior Sales Manager), who outlined the company's investment and growth plans for the Australian market.

Smart Energy Council Chief Executive David McElrea also addressed guests on the outlook for Australia's rooftop solar and home battery sector and the opportunity it presents for installers.

Partner network expands

The event celebrated SAJ's continued cooperation with One Stop Warehouse and the 1GWh deal signed earlier this year, and welcomed Supply Partners and Tradezone as the newest distributors of the SAJ range in Australia.

"SAJ has demonstrated the product capability, commercial bankability, manufacturing standards and technical approach we look for in a long-term distribution partner," Supply Partners CEO Patrick Morrissey said.

"We're excited to welcome SAJ to Tradezone. SAJ brings more than two decades of global experience and an innovative range of residential and commercial energy solutions to our customers. By combining SAJ's technology with Tradezone's online platform, distribution network and installer reach, we can provide Australian contractors with even greater choice and support," said Robert Kingston, Managing Director at Tradezone.
