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.

  • IP20 enclosure requires a suitable protected location.
  • Backup and off-grid layouts use different minimum module counts.

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