Affordable Storage, But Does It Deliver Long-Term Value?
Growatt is a global solar and battery brand from China, best known for its cost-effective inverters and energy storage products. In Australia, the company offers the ALP and APX battery series, which range from 5 kWh to 40 kWh and use safe lithium iron phosphate (LFP) chemistry. All models are Clean Energy Council–approved and can be installed outdoors, making them flexible options for households with different energy needs.
On paper, Growatt batteries look competitive: they are modular, scalable, and priced well below many premium alternatives. However, customer feedback in Australia often raises concerns about app quality, after-sales service, and brand trust, which hold them back from being a top-tier choice.
With an overall score of 67%, Growatt falls below our 70% recommendation threshold. While they may suit budget-conscious households or those already using Growatt inverters, most Australian homeowners will find stronger long-term value in alternatives from brands like Sungrow, BYD, or GoodWe.

Who Should Consider a Growatt Battery?
Growatt batteries are best suited for:
- Homeowners looking for a budget-friendly entry point into solar battery storage
- Households that already use a Growatt inverter, ensuring compatibility and easier integration
- Properties needing a scalable system, with capacity ranging from 5 kWh up to 40 kWh
- Installations where outdoor-rated batteries are required
They are less ideal for homeowners who value premium app features, long-term brand trust, and strong after-sales support. For those priorities, brands such as Sungrow, GoodWe, or BYD are often a better fit.
About Growatt
Founded in 2010 in Shenzhen, China, Growatt New Energy has grown into one of the world’s largest suppliers of residential solar inverters and energy storage products. The company distributes to more than 180 countries and has shipped millions of inverters globally.
In Australia, Growatt is positioned as a value-focused brand, offering solar inverters, hybrid inverters, and modular battery storage solutions. While its products are widely used due to competitive pricing, Growatt does not have the same long-established service footprint as premium brands like Tesla, BYD, or Fronius.
The company promotes its ALP (low-voltage) and APX (high-voltage) battery systems, both of which are approved by the Clean Energy Council and designed for flexible installation in Australian homes.

Support & Warranty
Growatt batteries sold in Australia come with a 10-year warranty, which is now the industry standard. Coverage typically applies to both capacity retention and product defects, provided the battery is installed by an accredited installer and used within normal operating limits.
However, Growatt’s local support presence in Australia is limited compared to brands like Sungrow, BYD, or Tesla. Installers often act as the first line of warranty processing, which can lead to delays if Growatt’s direct service channels are slow to respond.
The warranty conditions generally include:
- Coverage of up to 10 years or a defined number of cycles (usually 6,000+).
- Minimum guaranteed capacity of around 60% after 10 years.
- Valid only when installed and configured according to manufacturer guidelines.
While warranty length matches the market average, the real test is service responsiveness, where Growatt has mixed feedback in Australia.
We Have Great Answers
Ask Us Anything
Growatt batteries are designed for around 6,000+ cycles, which usually translates to 10–12 years of household use depending on daily cycling and operating conditions.
With proper installation and usage, most Growatt batteries should last at least their 10-year warranty period, though long-term data in Australia is still limited.
They are considered a budget-friendly option, with decent technical specs. However, user experience and after-sales support are weaker compared to brands like Sungrow, GoodWe, or BYD.
Yes, Sungrow generally rates higher in terms of performance, app experience, and local support. Growatt is cheaper, but Sungrow is often viewed as better value long-term.
No regular maintenance is required. Like most lithium batteries, they are sealed systems with a built-in Battery Management System (BMS) to manage safety and performance.
Growatt’s APX series is designed primarily to integrate with Growatt hybrid and AC-coupled inverters. Using other brands may not be supported.
Yes, Growatt inverters can operate without a battery. Adding a battery simply allows for energy storage and backup functionality.
Most Growatt batteries have a power button or reset switch on the module. Refer to the installation manual for exact steps, or contact your installer if issues persist.
A flashing blue light usually indicates that the inverter is attempting to establish a connection (such as Wi-Fi). Check the manual for troubleshooting or reconfigure the connection through the Growatt app.
