Solar Battery Tasmania
If you live in Tasmania, you’ve probably noticed power prices creeping higher year after year. Combine that with unpredictable weather and the occasional blackout, and it’s no surprise more Tasmanian households and businesses are investing in solar batteries (we would too).
At Solar Battery Group, we make the process simple. From supply and installation to ongoing monitoring and support, we’re here to deliver more than just a product… We’re here to provide long-term peace of mind and real savings.
What is Changing for Solar Customers in Tasmania in 2025?
July 1, 2025 has brought on a new rebate just for solar batteries.
The Cheaper Home Batteries Program is a federal government solar rebate that will offer around a 30% discount on eligible small-scale battery systems installed alongside new or existing rooftop solar. This was a program that was originally allocated a $2.3bn budget that has now been expanded to $7.2bn.
The best part? There are no postcode or income restrictions. It’s available to home and business owners (and even landlords).

How much can I really expect back from the rebate?
The rebate is delivered through Small-scale Technology Certificates (STCs) under the renewable energy scheme. All of Tasmania falls under Zone 4, with Hobart receiving around 3.7kWm/m² per day of solar radiation.
To be frank, this is the lowest STC zone (shared by southern Victoria and some southern areas in Western Australia). Which means Tasmania gets a lower percentage back from the Federal Battery Rebate compared to the rest of the country. Despite this, solar batteries have still become widely more affordable now than they have been before.
Tasmanians installing a 10kWh solar battery now can expect approximately $3,300 – $3,700 or more shaved off the cost of their installation.
If you want to get the most rebate back for your installation, you’ll also want to know that you will get back more the earlier you install. Changes to the Home Battery Rebate will mean that these values will now drop twice a year (in January and July) and battery capacities will now be treated differently through a new tiered system.
Please Note: Tasmania’s Energy Saver Loan Scheme (ESLS) has now ended.
Why Choose a Solar Battery in Tasmania?
Tasmania may be known for its cooler climate, but the state still enjoys strong solar potential. The challenge? Most of us aren’t home when our solar panels are generating peak power during the day. That means relying on expensive grid electricity at night. That is… unless you’ve got a solar battery.
With a solar battery, you can:
- Cut your bills dramatically (or entirely) by using your own stored solar power at night.
- Enjoy backup protection during blackouts, so you’re not left in the dark when the grid goes down.
- Increase your property value with future-ready energy solutions.
- Maximise your solar investment by storing excess energy instead of sending it back to the grid for low feed-in rates.
Smarter Energy with Solar Batteries
Today’s solar batteries are more than just energy storage; they’re smart energy managers. With integrated apps, you can track your energy use, see your savings in real time, and even control when your system buys or sells power back to the grid.
When paired with your solar panels and inverter, the right battery system can almost eliminate evening grid dependence and give you far more control over your energy future.
Solar Self-Consumption is Now the Smartest Way to Save
For Tasmanian households exploring solar and battery options, the biggest savings don’t come from exporting power — they come from using your own solar energy. With electricity prices around 26–30c per kWh and feed-in tariffs dropping to about 8.78c per kWh (2025–26), every unit of solar power you use in your home is worth almost three times more than exporting it.
Why This Matters
- Low export returns: Sending power to the grid earns under 9c per kWh.
- High self-use value: Using your own solar avoids paying 26c+ per kWh.
- Bigger savings gap: Self-consumption can deliver 16–20c more value per kWh compared to exporting.
In 2026, the smartest way to save with solar in Tasmania is simple: consume more of what you generate and reduce reliance on the grid. Besides shifting habits, one of the easiest ways to do this is with a solar battery.

Since July 2025, the launch of the National Battery Rebate, that number has increased exponentially. Alpha ESS solar batteries has been one of the top four selling battery brands for Australia in 2025, as a reliable and cost-effective battery that also makes it easy for installers to retrofit into existing solar system installations.
No matter the solar battery brand, these are the factors you want to look for when considering a solar battery retrofit installation:
-
- AC-coupling – AC-coupled batteries are one of the most common retrofit solutions for existing solar systems. In this setup, the battery system is installed alongside your current solar inverter and connected through the home’s AC switchboard. This means the solar energy generated by your panels is first converted to AC electricity by the inverter, then stored in the battery when needed. The key benefit of AC coupling is that it does not require replacing your existing inverter.
- Where DC-coupling works – DC coupled system is also an easy fit if your system uses a hybrid inverter
- Built-in Inverters – Some solar battery systems include integrated or built-in inverters, creating an all-in-one energy storage solution. These systems simplify the installation process because the inverter and battery are designed to work together within a single unit. For retrofit projects, this can reduce compatibility concerns and make system design easier for installers.

The key benefit of AC coupling is that it does not require replacing your existing inverter.
- Compatibility With Existing Solar Systems – Before installing a battery, it is important to ensure that it is compatible with your current solar setup.
This should include:
-
- Inverter type and brand
- Solar system size and output
- Electrical switchboard capacity
- Communication protocols between inverter and battery
Many modern battery systems are designed to be inverter-agnostic, meaning they can work with a wide range of solar systems. However, professional assessment by a qualified installer is essential before retrofitting.

How to Compare Different Solar Battery Features
A solar battery is more than just how much energy it can store. Looking at the key features helps you understand how the battery will work in your home and whether it suits Tasmania’s conditions.
-
Built-in Inverter
Some solar batteries come with their own inverter built in. This is helpful if you already have solar panels installed.
With a built-in inverter, you usually do not need to replace your existing solar inverter with a hybrid one. This can reduce installation costs and make the system simpler to set up.
For many Tasmanian homes that installed rooftop solar years ago, this makes it much easier to add a battery later.
-
UPS (Blackout Protection)
UPS stands for Uninterruptible Power Supply. It means the battery can switch to backup power almost instantly if the grid goes down.
This allows important parts of your home such as lights, the fridge, internet, and heating to keep running during an outage.
This feature can be particularly valuable in Tasmania, where storms and extreme weather can sometimes cause power outages.
-
LiFePO₄ (Cobalt-Free) Battery Chemistry
Many modern solar batteries use Lithium Iron Phosphate, also known as LiFePO₄.
This type of battery is known for being safer and more stable than some other lithium batteries. It also avoids using cobalt, which can have environmental and ethical supply issues.
LiFePO₄ batteries generally last longer and can safely use more of their stored energy. They also perform well across a wide range of temperatures, which is useful in Tasmania where winters can be cold and damp.
-
Modular Design
A modular battery system can be expanded over time.
This means you can start with a smaller battery and add more storage later if your energy needs increase. For example, you might expand if you buy an electric vehicle or add new appliances to your home.
For households planning ahead, modular systems provide flexibility without requiring a large upfront investment.
-
IP Ratings
The IP rating shows how well the battery is protected against dust and moisture.
Tasmania’s climate includes high rainfall, humidity, and coastal salt exposure in many areas, so this rating matters for outdoor installations.
An IP55 rating is generally considered suitable for outdoor use, while IP65 or higher offers stronger protection if the battery will be exposed to the elements.
-
AC Coupling
AC-coupled batteries connect to the alternating current side of your solar system and work with most existing solar inverters.
Because the electricity goes through a few extra conversion steps, there can be a small loss in efficiency. However, AC coupling is often the simplest and most practical way to add a battery to an existing solar system.
-
DC Coupling
DC-coupled batteries connect directly to the solar panels through a hybrid inverter.
This allows the energy to be stored before it is converted to usable electricity, which can improve efficiency slightly.
DC coupling is usually best suited to new solar and battery installations where both systems are designed together from the beginning.
Eligibility for the Federal Rebate
To qualify, your system must:
- Be between 5kWh – 100kWh (rebate capped at 50kWh)
- Be installed with a compliant solar PV system
- Appear on the CEC Approved Battery List
- Be installed or supervised by a CEC or SAA accredited installer
- Receive a certificate of compliance
The Federal rebate in SA can save homeowners up to 25% of upfront costs, based on the system.
Solar PV System and Battery Bundles in Tasmania
If you do not yet have solar panels, we offer solar PV and battery bundles designed specifically for Tasmanian homes. Installing both together allows you to combine the Federal battery rebate with the STC solar rebate, helping reduce the upfront cost of getting started with solar and storage.
Bundling your system also means everything is designed to work together from day one. Your solar panels, inverter, and battery are matched as a single system, which can improve overall performance and help you get the most value from your solar investment sooner.
How Much Can a Solar Battery Retrofit Help You Save in Tasmania?
For many households across Tasmania, including Hobart, adding a solar battery to an existing solar PV system can significantly reduce electricity bills. By storing excess solar energy during the day and using it in the evening, homeowners can rely less on grid electricity when prices are highest.
Tasmanians installing a 10kWh solar battery right now can also benefit from substantial upfront support. Current rebates can reduce the cost of installation by around $3,300 to $3,700 or more, which works out to roughly $330 to $372 per kWh of battery capacity.
How much you ultimately save will depend on a few key factors, including:
- Household energy usage and when you use electricity
- Participation in Virtual Power Plants (VPPs) or using a Home Energy Management System (HEMS)
- Battery performance and efficiency
- Charging and discharge cycles based on your solar generation
- Electricity prices and tariff structures in Tasmania
- Choosing the right solar battery system for your home

What’s Next? Smart Ways Tasmanian Households Can Get More From a Solar Battery
Installing a solar battery is a strong step toward greater energy independence. However, the real value often comes from how the system is used day to day. For households across Tasmania, including Hobart, understanding local conditions such as seasonal solar production and energy habits can help you get the most from your solar and battery system.
Below are several practical ways to maximise your savings.
Look Into VPP-Ready Systems and Future Virtual Power Plant Programs
Virtual Power Plants, or VPPs, connect many home batteries together so they can support the grid during times of high demand. In return, participating households may receive bill credits or other financial incentives.
In Tasmania, VPP options are still developing compared to markets like South Australia. TasNetworks has run several “battery neighbourhood” pilot programs, and some national providers such as ShineHub and SonnenFlat have started offering compatible systems.
Under the Federal Cheaper Home Batteries Program starting July 1, 2025, new grid-connected batteries must be VPP-capable to qualify for the rebate. This means that even if you do not join a VPP immediately, your system will be ready as more programs roll out across Tasmania in the future.
Use Your Battery Monitoring App
Most modern solar batteries include a monitoring app that lets you track your solar generation, household energy use, and battery charge levels.
These apps help you see exactly how your system is performing and when your home consumes the most energy. Many also allow simple automation, such as prioritising self-consumption or adjusting charging behaviour.
Over time, regularly checking this information helps households in Hobart and across Tasmania make smarter decisions about when to store energy and when to use it.
Understand Tasmania’s Winter Solar Production
Tasmanian solar systems produce strong energy output in summer but noticeably less during winter months. This is simply due to shorter daylight hours and the state’s southern latitude.
For example, a north-facing 6.6 kW solar system in Hobart produces much less electricity during winter compared with an identical system in Sydney. The seasonal drop in generation is significantly more pronounced in Tasmania.
This makes solar batteries particularly valuable. By storing excess energy during sunnier periods of the day, households can rely less on the grid in the evening or during cloudy winter conditions when solar production is lower.
Consider Panel Direction and Daily Energy Habits
Like most of Australia, north-facing solar panels produce the highest total energy output in Tasmania. However, Tasmania’s location creates some unique differences compared with mainland states.
In many parts of Australia, east- and west-facing panels tend to produce similar annual energy levels. In Hobart, this is not the case.
- East-facing panels produce roughly 90% of the energy of north-facing panels
- West-facing panels produce closer to 80%
Because Tasmanian mornings are often colder, households tend to use more electricity early in the day for heating and hot water. East-facing panels begin generating earlier in the morning, which can better align with these usage patterns.
For homes where energy use peaks in the morning, installing panels on an east-facing roof can sometimes provide better real-world benefits than a west-facing setup. However, households that use more electricity in the afternoon may still benefit from west-facing panels.
Use Stored Energy When Solar Production Drops
Solar panels generate less electricity in the evening, on cloudy days, and throughout winter. These conditions are common across Tasmania.
A battery allows you to store excess daytime solar energy and use it later when generation drops. Prioritising self-consumption in your battery settings ensures the power you produce during the day continues to support your home after sunset.
Take Advantage of Off-Peak Charging
Some solar batteries allow optional charging from the grid during off-peak electricity periods, usually late at night when energy prices are lower.
This can help keep your battery topped up during long stretches of cloudy weather or winter months when solar generation is reduced. It provides a useful backup strategy while still reducing reliance on higher-priced electricity during peak periods.
Use Energy-Efficient Appliances
The efficiency of your appliances has a direct impact on how long your stored battery power lasts. Upgrading to energy-efficient appliances, particularly for heating, refrigeration, and laundry, can significantly reduce electricity demand.
In Tasmania, where heating can be one of the largest household energy costs during winter, improving appliance efficiency can help stretch your stored solar energy further and increase the overall value of your solar battery system.
