A must view when considering the SMA Solar inverters for installation in Perth (and surrounds), Western Australia.

SMA solar inverters, like all solar inverters, aren’t immune to failure. In fact, many SMA inverters fail to see out their warranty period due to one common denominator.

Despite the exceptional product reputation, despite the rigorous German standards in quality control and despite the robust build quality, one factor remains the achilles heal of this proven solar inverter range.

Need to know.

95% of inverter failures are due to improper procurement and installation.

SMA can control the solar inverters integrity up until being dispatched from the factory. From there on, Germany to Australia, shipyards to distributors, distributors to installers, and finally to your house, the SMA product integrity is dependent on the supply network to uphold product integrity between factory and your installation.

To ensure trusted product integrity within the distribution and procurement network, SMA’s preferred channel is as follows;

SMA > Authorised Distributor > SMA PowerUP Partner > Your home.

As in many industries, non-authorised distributors will purchase SMA solar inverters through authorised distributors to sell combined packages possessing one of the worlds most in-demand inverter lines.

The result, an increase in the supply chain with unknown handling and procurement methods has the potential to diminish product integrity.


SMA PowerUP Partner
  • Sourced from an SMA Authorised distributor.
  • Minimal supply chain points of contact upholds product integrity.
  • SMA recommended shipping and handling methods adhered.
  • Additional training to ensure the SMA inverter is installed to guidelines.
  • Trusted installation - Complimentary 5-year warranty extension.


Non-certified Installer
  • Sourced from the lowest price distribution option.
  • Unknown - extra & untrusted points of contact reduces product integrity.
  • Unkown - incorrect shipping/handling has proven to cause internal damage.
  • Unkown - incorrect installation reduces inverter life expectancy.
  • Required to purchase additional 5-year warranty extension.

IMPORTANT: If SMA solar inverters are not handled or installed to SMA guidelines, your manufacturers warranty is rendered void.
