SMA has a comprehensive product portfolio in the market so you can build anything: from a grid-connected solar system for your home (with or without batteries) to a high end off-grid system with genset backup, to a commercial solar system that provides reliable power for your factory.

SMA Solar Technology was one of the first international manufacturers to enter the Australian market, providing jobs, industry training and leading edge products from their Sydney based headquarters. Globally, the SMA sales volume is expected to reach 1.5 billion AUD in 2016.

You can combine a SMA inverter with batteries for your home or business in Perth. In order to do so you will need the SMA Sunny Island (AC coupled battery inverter) system or their brand new Sunny Boy 2.5 Storage inverter. The SMA Sunny Boy Storage 2.5 is compatible with several leading storage solutions, including LG Chem Resu 10H and the BYD B-Box 2.5-10 home battery.

Consumption monitoring

The SMA Energy Meter (smart meter) allows you to measure your consumption at home or in your business. Combined with the SMA Home Manager device your energy consumption becomes easily accessible on your smart phone app or browser. Think the kids running the AC, or leaving all the lights on while you’re at work? Now you can prove it.


Where are SMA inverters made?

Most SMA inverters including the 3-phase Sunny Tripower models are made in Germany, near Kassel. The new single phase Sunny Boy range (SB 3.0, SB 4.0 and 5.0 AV) are made in the new SMA factories in China.


Can I connect a 6.5 kW array to a 5 kW SMA inverter in Perth WA?

Yes, it is possible, and in many cases recommended to oversize the inverter. This way you can maximise the STC rebate as well as your energy yield.
