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.

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.
