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 8 kW model may face network-export limits even where the household load target is valid.
  • Confirm the exact supported battery configuration and backup-circuit design.

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