What sets the price of a system with SMA inverters?
Installers quote SMA inverters as part of a whole system, so there is no stand-alone price we can source. System size, roof type, switchboard work and the federal STC rebate move the price far more than the brand. Our solar price guide covers installed cost by system size, and the STC rebate guide shows what comes off it in your zone.

Common questions about SMA
How much does an SMA inverter cost?
We have no sourced price for SMA inverters on their own. Installers quote the whole system, and its size, your roof and your switchboard move the price more than the brand does. Our solar price guide covers installed cost by system size.
What warranty does SMA give?
5 years (no registration extension in Australia) (SMA Australia, warranty page, checked 10 October 2026). Read the warranty document for the exact model you're quoted: conditions such as registration, cycles or capacity retention vary.
Where is SMA based?
SMA is headquartered in Germany. Ask your installer where the stock they're quoting was made, as manufacturing locations vary by product line.
Want SMA Sunny Boy inverters on your roof?
We pass your details to one SAA-accredited installer who can quote SMA where it's available in your area. The 30-second check confirms your postcode and rebates first, and the installer quotes the exact model for your home.
