In September 2026, solar and wind met 80.4% of electricity demand in Australia’s National Electricity Market (NEM) during a 30-minute period. This milestone highlights Australia’s energy transition and raises a key question: how can households store solar electricity and use it when needed? As rooftop solar expands, home battery storage can help Australian households increase solar self-consumption, manage electricity costs and improve energy resilience.
According to The Guardian, rooftop solar alone contributed more than half of NEM demand during the record period. The NEM covers Queensland, New South Wales, Victoria, South Australia, Tasmania and the Australian Capital Territory; Western Australia is outside this market. The 80.4% figure is a 30-minute record, not Australia’s annual average.
Australia is a leading rooftop solar market. AEMO data showed approximately 26.4 GW of rooftop solar across 3.9 million NEM installations by the end of June 2026.
Solar panels usually generate most electricity around midday, while household demand rises in the afternoon and evening. Without home battery storage, excess solar may be exported to the grid and households may buy electricity after solar generation falls. Batteries help retain solar energy for later use and shift demand away from peak periods.
Solar self-consumption is the share of rooftop solar electricity used in the home rather than exported to the grid. Households can run appliances during sunny periods or store surplus electricity in a home battery for later use. Shifting daytime solar into the evening can increase self-consumption and potentially reduce grid purchases, especially on time-of-use tariffs.
Smart energy management can coordinate generation, charging and household demand. Savings are not guaranteed; they depend on installation costs, solar output, battery capacity, tariffs, feed-in tariffs, losses and household consumption. Ask a qualified installer for a realistic estimate.
Introduced in July 2025, the Australian Government’s Cheaper Home Batteries Program supports eligible households, businesses and community organisations installing small-scale storage. Under arrangements updated on 1 May 2026, eligible systems generally range from 5–100 kWh nominal capacity, with STCs available for up to the first 50 kWh of eligible usable capacity. Support depends on capacity, installation date and certificate factors; equipment and installation must meet program requirements.
Anyone researching solar battery storage Australia costs should verify current incentives, approved equipment lists and installer requirements before purchasing. See the Australian Government’s Cheaper Home Batteries Program for details.
Some hybrid inverter and battery systems provide backup during outages, but not all do. Confirm backup capability, additional equipment needs and supported loads. Compatible smart platforms can monitor solar generation, battery state of charge, household use and grid imports or exports, and may schedule charging by tariff.
Founded in 2011, Growatt provides solar PV inverters, residential and commercial storage, battery technologies and intelligent energy management. It was recognised among the global top three hybrid inverter suppliers by 2025 shipment volume, according to rankings attributed to S&P Global Commodity Insights. In Australia, its solutions support solar self-consumption and home energy independence.
The Growatt All-in-One Energy Storage System (ESS) series—featuring the MINA and MODA—is designed for Australian homeowners seeking a streamlined, intelligent residential solar and battery storage solution. Unlike conventional configurations where major components are installed separately, MINA and MODA integrate the inverter and battery system into a clean, high-performance architecture.
Offers single-phase MINA (5–10 kW) and three-phase MODA (5–15 kW) options to suit diverse electrical scenarios.
Fully compatible with APX 2.0 battery systems, incorporating module-level battery optimizer technology for independent energy management while delivering flexible expansion up to 49 kWh.
Powered by Grade-A cells from tier-1 suppliers, offering exceptional durability with up to 10,000 cell cycles.
Features a built-in 63A bypass switch, ensuring seamless whole-home backup capability during outages for most Australian households.
Mainstream VPP ready, alongside an upcoming V2G DC charger module for bidirectional EV charging.
Engineered for efficiency with 10-minute quick wireless stacking between modules, complemented by 5-minute quick commissioning and diagnostics to drastically simplify installation and field support.
Engineered for Australian solar households, MINA and MODA efficiently store excess daytime solar power for seamless dispatch during peak evening demand or power disruptions. Replacing traditional, cumbersome multi-component setups, Growatt’s all-in-one residential energy storage solution offers a streamlined, future-proof approach to smart home energy.
In addition to MINA and MODA, Growatt provides flexible energy storage technologies tailored to diverse electricity requirements:
Growatt SPH and SPM Series: Ranging from 5 kW to 10 kW, these inverters pair with compatible Growatt battery systems to support up to 100 kWh of ALP battery storage, offering versatile solar-plus-storage configurations for residential applications.
Growatt MIN, MOD, and MID Series: Part of the same product family, these inverters currently span power ratings from 2.5 kW to 29.9 kW and pair with APX 1.0 battery storage to deliver up to 60 kWh of capacity—providing a flexible pathway toward energy independence. Looking ahead, the upcoming MID-HU series will expand capabilities up to 50 kW, matching with APX 2.0 batteries to achieve a massive total storage capacity of up to 252 kWh.
Growatt ALP and APX Battery Systems: Provide flexible, modular energy storage options. Combined with compatible monitoring and smart energy management platforms, they enable households to effortlessly track and optimise their power usage.
By offering integrated, modular and battery-ready solutions, Growatt aims to help Australian households select energy storage configurations that suit their roof space, electricity consumption, connection type and future energy needs.

Yes. In September 2026, wind and solar generation supplied a record 80.4% of electricity demand in Australia's National Electricity Market during a 30-minute period. This was a short-duration milestone, not the average renewable electricity share across Australia for the entire year.
Yes, a suitably sized battery can provide electricity during the night, depending on its usable capacity and the household's electricity consumption. Whether it can support an entire night of usage depends on the energy stored, appliance demand and operating settings.
Many existing rooftop solar systems can be upgraded with compatible battery storage. The installation approach depends on the existing inverter, electrical configuration, battery compatibility and applicable Australian installation requirements.
Australia’s 80.4% milestone highlights renewable energy progress and the growing role of distributed solar. The next phase requires households and the wider grid to store, manage and use renewable electricity when it is most valuable.
Combining rooftop solar with home battery storage and smart energy management can improve solar self-consumption, reduce grid purchases and strengthen household energy resilience. Growatt continues to support Australia’s transition through MINA and its broader hybrid inverter, battery and intelligent energy management portfolio.
