Secure your $4,000* SA Government subsidy for home battery storage before it reduces again.

Subsidies of up to $4,000* are still available under the South Australian Government’s Home Battery Rebate Scheme, so now is the time to add quality battery storage to your existing solar, or finally get that complete solar and energy storage package you’ve been thinking about. South Australia’s Home Battery Scheme means cleaner, more affordable, reliable power for every household that purchases a system. In addition, the installation of these systems will reduce demand on the network (especially during peak periods) and in turn, lower energy prices for all South Australians. With large subsidies on the cost of a battery and low interest finance available if needed, there has never been a better time to invest in solar and a battery for your home. Find out more here.

What is a and what does it do?

Solar batteries can help you make the most of your solar panels and increase your independence from the grid.

Solar batteries capture excess, unused energy produced by your solar panels, and store it ready for use at night, during cloudy periods, or during a blackout. Storing your self-generated solar energy means you can power your home with clean, green electricity 24/7. You’ll be protected from rising electricity costs from retailers, could have power in a blackout, and you’ll be helping to protect the environment from greenhouse gases from coal-generated electricity.

How does work?

Create and store electricity

Solar panels generate electricity from sunlight. This energy is used then and there to power your home or, if your home doesn’t need it straight away, it’s sent to your battery to be stored ready for use later on.

Use your energy when you need it

You can start using your battery stored electricity when your home’s energy needs become more than what your solar panels can deliver on their own. This could be on cloudy days, at night, or – most importantly – during a blackout.

Enjoy the benefits and lower your bills

Powering your home with solar panels and battery storage delivers you benefits for years to come. You’ll be making the most of your solar panels, maximising your energy independence, and lowering your ongoing energy bills.

Is a right for me?

If you already have solar or are thinking about making the switch, adding a battery system could help you get the most out of your solar system. Different systems suit different needs so it’s important to talk to one of our staff in order to help you make a more educated choice.

How much will

How much you could save on your energy bills depends on a number of factors including the output of your solar system and capacity of the battery, as well as the amount of energy your household uses and what time of day you use energy the most. We can help you calculate yourpotential savings when we do an analysis of your bill.

Can I

It’s important for all households to consider whether the savings they expect to see on their energy bills cover the cost of the purchase of the battery, over the life of the battery. System Providers can provide you with an idea of your anticipated savings. To get an idea of how much a battery system can cost, download the HBS System Price Guide. 

If you want to be as independent from the grid as possible, you might opt for multiple batteries and a large solar panel system to go with it, to maximise the amount of time your home can run from your solar panels and your battery instead of relying on the grid.

However, if your motivations are financial, you will need to balance your budget with how much you would like to save on your energy bills as well as your daily electricity usage. You might choose to go with just a single battery to suit your budget and maximise your payback, but this might also mean that you can’t cover off as much of your electricity bill: you may still be relying on a good amount of energy from the grid.

Introducing Residential

The Alpha ESS residential energy storage solution covers single phase 3 kW, 5 kW and three phase 10 kW, 16 kW, 20 kW this range is predominantly designed for PV self-consumption, back-up power, load shifting and off-grid solutions for household applications.


The Alpha ESS SMILE5 is a 5 kilowatt battery system. The battery modules are lithium iron phosphate, which is the safest type of lithium battery technology.  As an all-in-one system the SMILE5 can be DC coupled.  This involves connecting rooftop solar panels to its built in hybrid inverter, In this configuration the battery system can provide backup power during a blackout. If you already have a solar system installed it may be more convenient to AC couple the battery system. With this arrangement the battery system will be able to function no matter what type of solar inverter is already installed or what the solar panel capacity is.
