Growatt Launches Two New Products in Australia: High-Efficiency Inverter Paired with Flexible Energy Storage, Covering the Full Chain of Home Energy Use

With the growing adoption of electric vehicles, the shift from gas to heat pumps, and the normalization of working from home, Australian households are experiencing unprecedented growth in electricity demand. How to efficiently convert rooftop solar energy into everyday power, and how to flexibly store surplus electricity for times of need.

With the growing adoption of electric vehicles, the shift from gas to heat pumps, and the normalization of working from home, Australian households are experiencing unprecedented growth in electricity demand. How to efficiently convert rooftop solar energy into everyday power, and how to flexibly store surplus electricity for times of need—these are questions every household pursuing energy independence must address.

At the recent Smart Energy Conference & Exhibition (SECE) held in Sydney, global distributed energy leader Growatt delivered a clear answer: the MOD 5-15KTL3-HU three-phase hybrid inverter and the APX HV Battery 2.0 AU modular battery system. One focuses on ultimate conversion efficiency; the other on flexible energy storage expansion. Together, they form a complete chain from "generation—conversion—storage—consumption."

I. A Complementary Duo: Each with Its Role, Winning Together

Product Positioning at a Glance

MOD 5-15KTL3-HU: The Efficiency King

This three-phase inverter is purpose-built for high-consumption households—whether it's central air conditioning, pool pumps, or EV chargers, it handles them all with ease.

·       98.6% conversion efficiency: Among the highest-efficiency three-phase inverters available on the Australian market, meaning less energy is wasted as heat and more solar power truly serves the household.

·       DC/AC ratio of up to 2.0: Allows installation of solar panel arrays exceeding the inverter's rated capacity, providing ample room for future system expansion.

·       All-in-one design: Integrates inverter and backup power functionality into a single unit, eliminating the need for additional components, reducing wall space requirements, simplifying wiring, and lowering installation costs.

·       Seamless switchover during outages: Automatically switches to backup mode during grid failures, ensuring critical appliances continue to operate.

APX HV Battery 2.0 AU: Storage That Grows with You

Fixed-capacity batteries often fall short as household needs grow. The APX HV 2.0 is designed with the philosophy of "growing with the household," thoroughly addressing this pain point:

·       7 kWh modular stacking: Each module operates independently and can be stacked like building blocks for easy expansion, without complex series wiring.

·       Flexible scaling from 7 kWh to 49 kWh: Small households can start with a single module, while larger families can progressively add modules up to maximum capacity.

·       Plug-and-play design: Significantly reduces installation time and lowers installation costs.

·       Full compatibility: Supports both single-phase and three-phase systems. Paired with the MOD 5-15KTL3-HU, it creates Australia's most efficient and most scalable energy storage ecosystem.

Synergy: 1+1>2

The true value of these two products lies in their synergy. The MOD 5-15KTL3-HU handles efficient conversion and intelligent dispatch, while the APX HV 2.0 manages flexible storage and on-demand release. The two integrate seamlessly and offer a clear future upgrade path—something not every brand can deliver.

II. Reliability: Let the Data Speak, Let Strength Prove It

When choosing solar equipment, reliability is the most critical concern for household users. Growatt's reliability is not an empty promise—it is backed by independent third-party data:

Authoritative Certifications and Industry Rankings
