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 headline inverter rating can exceed battery-only output.
  • Full backup requires the approved switching equipment and installer design.

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