Australia’s high rooftop solar surge is driving interest in residential battery systems, according to Growatt, with hybrid inverters and modular storage technologies enabling households to capture more value from the electricity they generate.

Australia’s rooftop solar market is maturing. Therefore, attention is turning to how households can store and manage the electricity they generate.

For technology providers and installers, they have been focused on deploying photovoltaic systems to deliver integrated solar-plus-storage solutions that improve self-consumption and support a more flexible electricity grid.

Against this backdrop, Growatt is expanding its presence in Australia’s residential solar-storage sector. This expansion is marked by the introduction of new hybrid inverter and battery technologies, alongside initiatives aimed at strengthening installer engagement.

Founded in 2011 and headquartered in Shenzhen, China, Growatt develops photovoltaic inverters, battery storage systems, electric chargers and digital monitoring platforms for distributed energy systems. The company supplies its technologies to more than 100 countries and has established an early presence in Australia’s residential solar market through partnerships with local distributors and installers.

“Australia remains an important market for distributed energy solutions due to the scale of rooftop solar deployment and the increasing interest in residential storage,” says Lisa Zhang, Vice President at Growatt.

Hybrid inverter for integrated systems

Central to Growatt’s current offering is the SPM 8000-10000TL-HU hybrid inverter, designed for residential and small commercial solar-plus-storage systems. The single-phase inverter enables solar generation, battery storage and grid interaction within one device.

“The aim of hybrid inverter technology is to allow solar generation, battery charging and grid interaction to operate within a unified platform. This simplifies system integration and provides households with greater control over how solar energy is used,” Zhang says.

The inverter offers an output capacity of 8-10 kilowatts and incorporates three maximum power point tracking inputs to optimise energy generation from rooftop arrays. With a peak efficiency of around 97.5 per cent, the system is designed to support both new solar installations and retrofit battery additions through direct current or alternating current coupled configurations. The unit also includes uninterruptible power supply functionality with a switching time of approximately 10 milliseconds, allowing systems to provide backup power during grid outages. Up to six inverters can be connected in parallel, enabling larger residential or small commercial installations.

“The flexibility to operate across different installation scenarios is an important design consideration,” Zhang says.

“Installers require systems that can adapt to varying household energy requirements and rooftop configurations.”

Modular battery storage and installer engagement

Complementing the inverter is Growatt’s ALP 5.0L-E2 lithium iron phosphate battery module, a modular storage system intended for residential energy storage.

Each battery module provides five kilowatt-hour (kWh) of nominal capacity and approximately 4.6 kWh of usable energy. Multiple units can be connected in parallel, allowing storage systems to scale from smaller residential installations through to larger household storage configurations.

“The modular design allows storage capacity to expand as household energy consumption evolves,” Zhang says.

The battery uses cobalt-free lithium iron phosphate (LiFePO₄) chemistry, which is widely used in residential energy storage due to its thermal stability and long cycle life. Growatt states the system is capable of more than 6000 cycles under standard operating conditions.

An integrated battery management system monitors temperature, voltage and current to maintain safe operation. The battery also carries an IP66 rating, enabling both indoor and outdoor installation.

Beyond hardware, Growatt is also focusing on digital tools designed to support installers during commissioning and system management.

Through the ShineTools platform, installers can configure and activate systems via a mobile application that connects devices to Growatt’s monitoring ecosystem, including ShinePhone and ShineServer.

“Digital commissioning tools help streamline installation and enable installers to monitor system performance remotely. This can improve operational efficiency and provide better visibility of system performance,” Zhang says.

The digital platform is linked to Growatt’s installer incentive program introduced in Australia to encourage battery deployment.

Under the program, installers receive rewards each time a Growatt battery is installed and activated through the ShineTools application. Incentives vary depending on the monthly campaign and are credited once the system is commissioned and connected to the monitoring platform.

“Installers play a central role in the adoption of residential battery systems. Providing commissioning tools alongside incentive programs is intended to support installers and encourage wider uptake of storage technologies,” Zhang says.

Growatt’s approach reflects a broader trend in Australia’s solar industry, where increasing battery adoption is expected to complement the country’s high rooftop solar penetration.

“As distributed energy resources continue to expand, integrated solar and storage systems will play an increasingly important role in how households manage electricity,” Zhang says.

“Technology development and installer engagement will both be important factors in supporting this current transition in battery storage across Australia.”
