What Are Solar Batteries?
A solar battery is a rechargeable storage system that saves the excess energy your solar panels produce. Instead of sending surplus power back to the grid, the battery stores it for later use. This helps reduce electricity bills and keeps your home powered during a blackout.
In Melbourne, most solar batteries are lithium-ion because they:
- Store more energy in less space (high energy density).
- Last longer than lead-acid batteries (often 10–15 years).
- Require little to no maintenance.
- Lose around 10% of energy during charging and discharging.
When your solar panels generate more power than your home is using, the extra energy is sent to the battery instead of the grid. The stored energy can then be used later in the evening or during a blackout to keep your home running.
Battery Options to Suit Your Needs
Most solar batteries in Melbourne are lithium-ion, which are long lasting and low maintenance. Options include:
- High-capacity batteries – store more power for everyday household use.
- High-power batteries – deliver short bursts of energy when demand is high.
- LFP batteries – reliable, with slower capacity loss in the first year.
- Modular systems – expandable setups that let you add more storage later.
- Tesla Powerwall 2 – a popular all-in-one system with neat design and proven performance.
Backup Power and Setup Options
Most batteries switch automatically to backup mode during a power outage, but not all perform equally under load. Some homes need additional hardware to power larger appliances.
When choosing a system, you can opt for:
- All-in-one solutions (like Tesla Powerwall) that combine battery and inverter in a neat unit.
- Separate battery and inverter setups, which may require more installation work but can be more flexible.

Why Solar Batteries Are Worth It in Melbourne
Melbourne households face rising electricity costs, with summer peak rates often above 50 cents per kWh. Hot weather also pushes demand higher as air conditioners run longer, and storms bring frequent blackouts across Victoria.
A solar battery system helps you take control by storing the power from your installed solar panels so you can use it when energy is most expensive, or when the grid goes down.
Who Should Consider Solar Batteries in Melbourne
- Families with high evening electricity use.
- EV owners charging vehicles overnight.
- Homes that rely on medical equipment or home office setups.
- Properties in suburbs prone to blackouts during storms or summer heatwaves.
Key Benefits of Solar and Battery Systems
- Cut electricity bills by using stored solar power during costly evening peak times.
- Stay powered during outages, keeping lights, internet, and refrigeration running.
- Reduce reliance on the grid by using more of your own clean solar energy.
- Prepare for the future with support for EV charging and smarter home energy use.

Installation and Maintenance of Solar Batteries
A safe and reliable battery installation is essential for any solar and battery system. In Australia, only licensed electricians can install solar batteries, and every system must comply with Australian Standard AS5139 to meet strict electrical safety requirements.
What to Expect During Installation
- Installation usually takes a full day and requires at least two qualified installers.
- The battery must be mounted securely to a wall or floor in an approved location for safe outdoor installation or indoor use.
- The system is connected to your solar panels, solar inverter or hybrid inverter, and the electricity grid for seamless operation.
- Some batteries, including the Tesla Powerwall 2, may need extra hardware to provide backup power during a power outage.
- Modular battery storage systems can be expanded over time, giving households more flexibility as their energy stored and battery capacity needs grow.
Professional installation ensures your solar battery storage integrates smoothly with an existing solar system or a new solar pv setup. This maximises solar self-consumption, helps you make the most of surplus energy, and can further reduce electricity bills.
Maintenance Requirements
Most modern solar batteries are easy to look after. Once installed, they work on their own and don’t need regular servicing. To keep your system running well:
- Have your installer check the battery every so often to make sure it’s safe and performing properly.
- Use the battery’s mobile app or display screen to see how much power is stored and used each day.
- Keep the area around the battery clean, dry, and well-ventilated, especially if it’s outside.
- If the battery brand offers software updates, your installer may apply these during a routine check.
With the right care, a lithium-ion solar battery can last 10–15 years, helping you reduce electricity bills and keeping your home powered during a blackout.

Government Rebates for Solar Battery Storage
Installing solar batteries can be much more affordable with help from government rebates and incentives. Both federal and state programs are available across Australia, making it easier for households to cut energy bills and improve energy independence.
Federal Battery Rebate
The federal battery rebate lowers the upfront cost of home battery installations by around $330 per usable kilowatt hour (kWh). This applies to approved battery storage systems, including popular options like the Tesla Powerwall and other lithium-ion models.
The rebate can be combined with state rebates, reducing solar battery prices even further. Eligible systems must meet Clean Energy Council (CEC) standards to qualify.
State-Based Rebates and Incentives
- Victoria – The Victorian Government offers a rebate of up to $4,174 for eligible households. To qualify, you need a combined household income under $180,000, a property valued under $3 million, and either an existing solar system or a new system installed at the same time.
- Western Australia – The WA Residential Battery Rebate Scheme provides rebates of up to $3,800. Interest-free loans of up to $10,000 are also available for battery installation.
- New South Wales – NSW residents can access a Virtual Power Plant (VPP) incentive of $55 per kWh of battery storage, capped at 10 kWh. This helps households earn credits for joining programs that share excess electricity with the grid.
These rebates and incentives can be used together with the federal rebate, giving households bigger savings and shorter payback periods.
Why Apply Now
Government rebates reduce the solar battery cost by covering part of the purchase and installation costs. This makes solar and battery systems more affordable and helps homeowners:
- Reduce electricity bills by storing surplus energy.
- Provide backup power during a power outage.
- Improve solar self-consumption by using more of the energy their solar panels produce.
- Cut carbon footprint by relying less on grid electricity.
