- Performance Warranty: Solar battery warranties often include a performance guarantee, ensuring that the battery will retain a certain percentage of its capacity (usually around 70-80%) after a set number of years, often ten years. This ensures the battery remains effective over time.
- Cycle Count: Warranties may also be tied to the number of charge and discharge cycles. Solar batteries typically come with a guaranteed number of cycles, such as 5,000 to 10,000 cycles, representing how many times the battery can be fully charged and discharged during its warranty period.
- Coverage for Defects: A solar battery warranty also covers manufacturing defects or malfunctions. This protects faulty components or issues that may arise from poor manufacturing, ensuring repairs or replacements within the warranty period at no additional cost.

BATTERY WARRANTIES
Solar battery warranties are guarantees provided by manufacturers to ensure the performance and durability of a solar battery over a specific period.
Battery warranties can be separated into three main chunks: the lifespan and coverage of the battery itself, shipping and labour coverage details, and warranty exclusions or exceptions
HOW DOES A SOLAR BATTERY BENEFIT YOU
Energy Independence
Solar batteries allow you to store excess energy generated by your solar panels during the day. This stored energy can be used at night or on cloudy days, reducing your reliance on the grid and potentially lowering your electricity bills.
Backup Power
In case of power outages, a solar battery system can act as a backup power source. This ensures that essential appliances and systems in your home continue to function even when the grid is down.
Maximizing Solar Investment
You can maximize the use of your solar system by storing excess solar energy instead of feeding it back to the grid. This is particularly beneficial in areas where net metering policies are less favourable, allowing you to use more energy you produce.

Without a Solar Battery
- Excess energy is fed back to the grid
- Reliance on grid power during non-sunlight hours
- Vulnerable to power outages
- Limited control over energy usage and costs

With a Solar Battery
- Excess energy is stored for later use
- Self-consumption of solar power 24/7
- Backup power during grid outages
- Greater energy independence and cost control
FREQUENTLY ASKED QUESTIONS
Both residential and commercial premises are eligible for the battery incentive. The incentive is not provided directly to customers. Instead, it is usually applied as an upfront discount by the approved supplier responsible for installing the battery.
- Residential or Small Business site
- Have an existing solar PV system or are having solar PV installed at the same time as the battery
- No existing battery installed at the property (address is determined by the electricity National Meter Identifier (NMI)
- The total battery system capacity cannot be 28kWh or more (multiple batteries can be installed at the same time)
- Each battery model must:
- Be listed on the Clean Energy Councils approved battery list.
- Have a capacity of more than 2kWh and less than 28kWh
- Be capable of being connected to a VPP
- Meet specific warranty conditions
In most instances, the cost of installing a solar battery will include the battery unit, labour, and materials involved in such installation. To avoid surprises, it is good to ascertain what is included in the quoted price with the installer.
Yes, it is safe to install a battery, provided it is done by a qualified professional following the manufacturer’s guidelines and local safety regulations. Modern battery systems, especially those used for solar energy storage, are designed with multiple safety features to prevent issues like overheating, overcharging, and electrical faults. Ensuring proper installation and regular maintenance will further enhance safety.
Yes, you can choose the model of the battery you install. We offer a range of options from
various manufacturers, allowing you to select the one that best fits your needs in terms of capacity, efficiency, and budget. Our team can provide guidance to help you make the best choice for your system.
Yes, you can retrofit a battery to an existing solar panel system. However, compatibility should be checked, and you may need to upgrade your inverter or install a battery which has inverter built in.
Most modern solar batteries have a lifespan of 10-15 years. However, this can vary depending on the battery type, usage patterns, and maintenance. Some high-quality lithium-ion batteries may last even longer.
A Virtual Power Plant (VPP) is a network of distributed energy resources, like solar panels and batteries, that are connected and controlled as a single power source to support the grid. You can join a VPP by installing a compatible solar and battery system, then signing up with a VPP provider that manages and aggregates the energy from your system.
Batteries connected to a VPP must meet the following criteria to be eligible to claim the rebate:
- Be a residential site
- Have solar PV installed at the same site (NMI)
- No Life Support Equipment in use at the site
- The total battery system capacity cannot be 28kWh or more
- Each battery model must:
- Be listed on the Clean Energy Councils approved battery list when connected to the VPP.
- Have a capacity of more than 2kWh and less than 28kWh
- Have a minimum 6 years remaining on the warranty
- Meet specific warranty conditions
This range is consistent with schemes in other Australian states. Most sites will only require batteries under 28kWh, considering the national average energy use for a five-person household is 25kWh per day.
