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.

  • Confirm the exact approved model and release status before ordering.
  • 15 kW depends on solar input and temperature. A backup installation requires Backup Gateway 2.

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