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.

  • The Australian page does not expose enough current model-level approval detail for the family name alone to establish eligibility.
  • The broad 3–10 kW label covers materially different configurations, so backup output and capacity must be confirmed together.

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.
