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 larger stacks require a different listed system code. Check supply phase, export limits and backed-up circuits.
  • Installed pricing for the exact configuration requires a supplier quote.

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