Decarby Solar is a solar and home electrification company based in Mitchell, Canberra, providing consultancy, design and installation services for residential and commercial properties. Helping families navigate the switch to solar with practical, real-world advice. Bec focuses on the financial side — rebates, bill savings, and financing options — so everyday Australians can see real value from going solar.
From residential battery systems to large-scale commercial energy storage and intelligent energy management software, RedEarth helps Australians take control of their energy future. Or if you’re ready to add battery storage to your home, SolarQuotes can help you compare up to three quotes from trusted, vetted installers who know commercial solar battery solution queensland how to get the important details right. Founded by former Huawei solar executive Tony Xu, Sigenergy has pioneered the concept of an integrated, stackable system combining battery storage, a hybrid inverter and optional DC EV charging. For most grid-connected systems, having a battery doesn’t necessarily protect you in the event of a blackout.

Instead of sending the excess energy back to the grid, solar batteries work by storing energy for later use. Some all-in-one batteries are sealed units that cannot be extended. Choose a modular battery storage product the manufacturer lists as expandable, and confirm your installer stocks compatible modules. A modular solar battery in Australia is built from separate battery modules that connect to one another, rather than a single sealed, fixed-capacity box. Each module usually adds a set amount of usable storage, commonly 5kWh to 10kWh, so capacity grows in predictable steps.
However, it became popular in the early 2017 release of the Tesla Powerwall 2. The BYD battery is another modular, stackable battery that is a great value option for homeowners. Being able to add 2.76 kWh units as needed, provides system owners with flexibility as their electricity habits change. You need assess whether or not the battery can be configured to do what you want it to do.

The proposed new three hours of free electricity offer will only further benefit battery owners. For many Australians, installing a battery is now, financially and environmentally worthwhile. You can evaluate the viability of adding storage to an existing system using our battery calculator. It may be that the price determines the size of the battery or, you can figure out what size battery you need.
Consider using online calculators and seeking expert advice to weigh the costs, savings, and potential future benefits before making a decision. Energy Matters can help you make an informed decision and the perfect option on the suitability of a solar battery with our Solar Power and Battery Storage Calculator. WA offers zero-interest loans for batteries as part of its WA battery rebate. In practice, most home batteries discharge an average of less than their full usable capacity each day. If you’re planning to discharge your battery more than this, you will normally be financially better off installing a larger battery. Throughout Australia, average payback times on solar panel and battery systems range from 5.8 years to 9.6 years.

One of the biggest reasons Australian homeowners choose Sungrow batteries is their exceptional value for money. Sungrow delivers premium battery technology, reliable performance and advanced energy management features at a more accessible price point than many competing battery brands. Experienced installers do much more than install the battery itself. They optimise the entire solar and battery system to maximise energy savings, improve battery performance, enhance system efficiency and ensure long-term reliability. A professionally designed Sungrow battery system can help Australian homeowners achieve greater energy independence and maximise the return on their solar investment.
You can find their contact details on the invoice or contract from your installation. We may share installation information with state and territory regulators to ensure compliance with their schemes. Claiming the whole capacity of the expanded battery system may be considered fraud or making false and misleading statements to the Commonwealth. Adding battery modules to a stackable battery system is a normal practice and can be undertaken safely when meeting the manufacturer’s requirements and Australian Standards.

Here are approximate battery costs (after the current federal rebate) for common sizes, including basic installation. Prices are based on information from our solar partners, SolarQuotes. It is important to choose the right size solar battery for your needs. You can’t claim STCs for future additional solar batteries at the same premises if you decide to upgrade to a larger system later. Talk to your retailer to make sure the solar battery you choose is an appropriate size for your inverter, and it meets your current and future energy requirements.
Thanks to the federal battery rebate, solar batteries are now more affordable than ever, with thousands shaved off their upfront costs. All battery prices listed below already include this rebate as well as GST. At Off Grid Solar Kits, we pride ourselves on being a one-stop shop for your sustainable energy storage equipment and products designed to withstand Australian conditions.
STCs can only be claimed for the first 50 kWh of a solar battery’s usable capacity. This is the amount of energy that can be discharged and represents the power that a home or business can draw from the solar battery. If your fixed home battery drains to 0% during a multi-day blackout, it often doesn't have the juice to wake up your solar panels the next morning. A portable unit like the Apex 300 (2,764.8Wh) can provide a black start, jump-starting your inverter so your roof can start harvesting energy again.

We review the best hybrid inverters from the leading manufacturers for battery storage and backup power. For example, it is possible to run energy-intensive appliances such as dishwashers, air-conditioners and washing machines (not all simultaneously) for free using your solar energy during the day. Also, many ‘smart’ appliances can now be remotely turned on or activated using timers to operate when there is excess solar energy, rather than sending it to the grid for very little return. Many modern solar inverters are also ‘battery-ready’ hybrid inverters, which makes it easy to add battery storage in the future.
Yes, solar batteries can significantly reduce your electricity bills and offer a path to greater energy independence. While the initial investment is substantial (typically $8,000 to $15,000 installed), the long-term savings often make them a worthwhile consideration for homeowners with solar panels. If you're buying panels and a battery together, it's cheaper to fit both in one go, so it's worth knowing what to expect during solar panel installation. The amount of battery storage you need depends on your specific energy consumption and solar panel generation capacity. Factors like household size, daily electricity usage, and desired level of energy independence all play a role.
