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.

  • Several product generations share similar branding, making exact model identification important.
  • Warranty throughput, inverter compatibility and backup capability need to be checked against the quoted generation.

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