With electricity prices continuing to climb and Melbourne households generating more solar energy than ever, the question is no longer whether to add a battery it's which one. A well-matched solar battery lets you store the power your panels produce during the day and draw on it at night, reducing your reliance on the grid and shielding your home from volatile energy costs.
Two names consistently rise to the top of conversations among Melbourne homeowners: the Tesla Powerwall and the Sungrow battery system. In 2025, Tesla and Sungrow actually tied for first place in installer surveys. Tesla Powerwall battery installation in Melbourne remains enormously popular, thanks to the brand's reputation for premium performance, an intuitive app, and full-home backup capability.
The Sungrow battery system, meanwhile, has surged as a compelling alternative, offering solid storage capacity and competitive pricing, with a 10-year warranty and a compact design well suited to Australian homes.
In this article, we’ll tell you why solar energy is taking off in Melbourne, and we’ll compare the two top brands Jet Solar install for our happy customers. Hopefully, this will help you make the decision on which one is best for your home and your budget.
Solar panels are already growing in popularity in Melbourne. In fact, the city of Melbourne is in the top five cities in the world for rooftop solar panel installation and adoption. Approximately 31% of Victorian homes have solar panels (Source: Sustainability Victoria), and through the Solar Homes Program, the aim is to reach a million homes by 2030.
Solar batteries are growing in popularity in Melbourne, and are often installed with the solar panels, for a few reasons. The combination of rising electricity costs and lower feed-in tariffs means people are more likely to want to store excess energy to use ‘after hours’. Victoria is also trying to move away from gas, onto a fully electrified grid, so having a battery integrated with your solar system helps to maximise the efficiency of this system.
The Victorian Government has solar home schemes to help with the costs of installation. The Federal Government, too, has a rebate and loans scheme for solar installations. Specifically for home batteries, the Federal Government has a ‘cheaper home batteries program’ to assist people to install a solar battery to store excess energy to use at a later time, further helping you to remain off grid and save money on your electricity bill.
Solar batteries are also popular for reliability. Each summer the topic of power conservation arises in the news, and talk of rolling blackouts to help maintain power is brought up. Having your own solar system with a battery will protect you from such blackouts, keeping your home powered, no matter what. It also helps with the increasing storms and extreme weather conditions, when powerlines are brought down by falling branches.
Melbournians are also highly proactive when it comes to the environment. Getting off grid, less reliance on coal-fired power stations and more reliance on renewable energy, and being able to charge the growing number of EVs on Melbourne roads, is driving the popularity of solar batteries.
Having a solar battery also increases a home’s resale value. More homeowners are shifting from just solar, to solar + battery installations, both for the savings they make on their electricity bills, and for the value it brings their home.
Jet Solar sells both the SBR Sungrow battery range and the SBH range.
The Sungrow SBR Series battery is a high performance battery with up to 30A continuous charging and 100% usable energy. (from our website) They are an advanced, modular battery storage system and can be expanded if your energy needs or your solar system grows.
The SBH range of Sungrow batteries are high powered batteries with up to 50A continuous charge and discharge current. They can support 4-8 modules per unit with a maximum of 4 units per installation. Stackable and modular they really are a plug and play dream, with no cables between modules.
In Australia, Sungrow represents excellent value for money. They have features similar to the big European brands but at a lower cost, making them great value for money in the Australian marketplace.
They are extremely reliable and have peak performance in Australia’s hot conditions. As Jet Solar installs and supports this brand, with a competitive 10-year warranty, you know this reliability is going to extend for many years.
They are also highly efficient, with high conversion rates of around 98% for residential models. This gets almost every last drop of solar power from your panels.
The Sungrow brand was the top seller of both inverters and batteries in Australia for 2024, showing their popularity in the local market.
Tesla is a brand we all know, and the Tesla Powerwall 3 is an exceptional battery product from this company. The Powerwall 3 is an integrated solar inverter that converts solar energy into stored, single-phase home electricity very simply. They’re excellent for charging up EV cars, and have a robust and spectacular app to manage and monitor the whole process.
The built-in inverter is a time and money saver for you. The Powerwall 3 is very capable of handling peak electricity loads and is excellent in summer conditions when running your air conditioner for long periods of time.
This brand is great for Australian conditions. The app can warn of potential storms, so the system will charge the battery to maximum, ensuring there is power in case of power outages due to winds or falling branches.
The Powerwall 3 is also scalable. It can handle up to 20kW of solar input, and you can link up to 10 units for higher energy storage and usage. THis higher capacity of storage gives you real confidence that you will still have lights and refrigeration during a black out.
The system is water and dust resistant and uses a lithium iron phosphate chemistry.
Like the Sungrow, the Powerwall 3 has a 10 year warranty and is solidly backed up and supported by Jet Solar and our crew.
Jet Solar stocks the Powerwall 3 expansion pack. This allows you to upgrade and expand your Powerwall 3 system as your energy needs grow. Your might be growing your family, or you may have purchased a Tesla Model Y L, this pack can have you stacking up to an additional 3 units, all integrated and linked through the Tesla app.
This expansion pack lets you continue with your Tesla hardware scaled to fit your lifestyle.
The Tesla Powerwall 3 and the Sungrow Solar Batteries are both excellent choices for a Melbourne home. They both have 10 year warranties and total support from the Jet Solar team after installation.
For budget conscious homeowners who want to start on the solar powered journey but can’t jump in too deep, the Sungrow is the best option for you. It is easily scalable as your capacity to grow increases.
The Tesla Powerwall 3 is best for high-energy using households, such as large families and those with electric vehicles. The all-in-one system is convenient and with a high-power backup you won’t be caught unawares when Melbourne's extreme weather strikes without warning.
The team at Jet Solar assesses your home and your electricity use, directly from your bill, to give you the best option for the solar system. We’re not going to sell you the biggest and most expensive, but the one that fits your needs. We deliver, install and provide top class after-sales service so you’re never caught without power.
