Why Add Solar Battery to Your House?
Installing solar power offers a wide range of benefits. It not only promotes energy independence but also significantly lowers your electricity bills. With just a one-time investment, you can enjoy long-term financial returns.
Receive up to $16,800 in government rebate when you install a 50kWh battery system — a valuable asset for your home. This can help us save a lot in the first step.
Lower your electricity bills by utilising stored energy during peak times. Even if your household electricity consumption is high, you don’t need to worry about overspending on electricity bills
Under certain circumstances, excess electricity can be delivered to the national grid and subsidized. Subsidy amount: FiT standards vary between states and electricity retailers, usually ranging from 5 to 15 cents per kWh (approximately RMB 0.24 to RMB 0.72)
If you build an off-grid system, you’re creating a dedicated power station for your family. It not only provides stable power to everyday appliances like refrigerators, air conditioners, and washing machines, but also charges electric vehicles and supports smart home operations.
From ensuring lighting during power outages to managing energy consumption during peak hours, it enables true energy independence and smart management for your home.
Under the latest 2025 policy, the government offers energy storage subsidies of up to AU$372 per kWh, meaning you could receive over AU$15,600 in installation support. Once the system is installed, you can save up to AU$2,300 annually on electricity bills, and return excess electricity to the grid through the feed-in tariff, generating ongoing revenue. With rising electricity prices and favorable energy policies, the cost is expected to be recovered within 5–7 years, with net profits every year thereafter.
One investment, long-term returns, transforming your home from an electricity consumer into a generator.

50kW Solar Battery System
Built for Australian Living
Unlike 10-15kWh home energy storage systems, the 50kWh system is better suited to the electricity needs of medium- and large-sized households. Most Australian households use between 15 and 20 kWh of electricity per day. Therefore, a 5 kW inverter paired with a 50 kWh battery is still suitable for many households. We’ve seen this in many installation cases.
The main function of large-capacity batteries is to buffer against cloudy or rainy days, providing power for several days if solar power generation decreases.
If a 5kW single-phase inverter cannot meet your daily needs, we can also provide 10kW or 15kW inverters or three-phase inverter solutions, depending on your specific requirements. Please contact us for further details.
If you own multiple properties, consider installing or upgrading solar energy storage systems across each location. This not only enhances energy efficiency and reduces electricity costs, but also increases the overall value and sustainability of your real estate portfolio. By harnessing clean energy, you’re investing in long-term savings and contributing to a greener future！

Act Now to Maxmize Your Rebates
The Australian Government has announced intended changes to the federal government’s home solar battery rebate that are subject to regulations being made, and are proposed to start on 1 May 2026.
Change 1: The rebate amount declines more frequently and faster (every 6 months instead of annually).
Change 2: The rebate factor tapers by battery size (full support for typical household sizes; reduced support for larger systems).
① 0–14 kWh: 100% of STC factor
② 14–28 kWh: 60% of STC factor
③ 28–50 kWh: 15% of STC factor
If you are planning to install a large-capacity battery(over 28kWh), we recommend that now is a suitable time to proceed. Please contact QH for more information and installation suggestions.
From May 2026, your rebate value drops every six months

FAQ - Australian Off-grid Solar ESS
If you have any questions, please take a look at the following Q&A! If your question is not answered, please send us a message!
Yes, now is a great time to invest in solar energy in Australia. With generous federal subsidies like the Small-scale Renewable Energy Scheme (SRES) and the new Cheaper Home Batteries Program offering up to 30% off battery systems, households can significantly reduce upfront costs
Yes, solar energy storage systems can be fully customized to suit your household’s energy needs. Whether you require more than 50kWh for EV charging or less for basic backup, modular battery systems like Felicity allows flexible scaling. Under Australia’s Cheaper Home Batteries Program, eligible households can receive up to 30% off battery costs, making both large and small systems more affordable. With rising electricity prices and generous rebates, tailoring your solar-plus-storage setup ensures optimal savings and energy independence—especially for off-grid or high-consumption homes.
The primary consideration is your available solar power generation capacity. If your array is small, a 10kW inverter can help you make the most of idle periods or upcoming solar sharing periods. Larger arrays typically also require a 10kW inverter to avoid power generation limitations.
The main advantages of three-phase inverters are higher power output, more stable voltage, and higher efficiency, making them suitable for high-power applications; while single-phase inverters are cheaper and simpler in structure, making them suitable for homes and small systems.
If your home has three-phase electricity, it’s best to choose a three-phase inverter. When your appliances need power, the inverter will distribute the power evenly across the three phases. If you choose a single-phase inverter, the battery will only discharge from one phase, while your appliances require three-phase power, resulting in lower efficiency.
Maintaining a solar system in Australia is simple and cost-effective. For typical households, regular cleaning of solar panels every 6–12 months helps maximize efficiency, especially in dusty or coastal areas. It’s also important to check for shading from trees and inspect wiring for wear. Battery systems like Alpha requires minimal upkeep but benefit from annual health checks. Most inverters and monitoring apps alert users to faults automatically. With generous warranties and sunny conditions, Australian families enjoy reliable solar performance with very little maintenance.
Yes, our batteries are designed with safety as a top priority and meet Australia’s strict installation standards, including AS/NZS 5139 for battery storage. Systems like Alpha includes built-in Battery Management Systems (BMS) that monitor temperature, voltage, and charge levels to prevent overheating or overcharging.
In Australia, certified installers ensure proper placement, ventilation, and fire safety compliance. Most households opt for wall-mounted or outdoor-rated units with IP65 protection, making them safe even in coastal or high-heat environments. With professional installation and regular system checks, solar batteries are a reliable and secure energy solution.
