Our opinion

The buying view.

EDITORIAL OPINION - BASED ON THE CITED RESEARCH

Cons and watch-outs

What to check before buying.

These are configuration trade-offs and questions to verify, not claims that the product is defective.

  • Overlapping SMILE and SMILE-G3 names make exact battery and inverter codes essential.
  • The wide configuration range means warranty, phase, power and backup assumptions cannot safely be made at family level.

Ask for these points to be answered against the exact model numbers and installed configuration in your quote.

Evidence trail

Check the sources.

Specifications can change by model revision, region and paired hardware. CEC approval is not proof of current availability or suitability. Confirm the model and final design with the manufacturer and an accredited Australian installer.
