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.

  • Backup operation requires controller and balance-of-system hardware beyond the battery modules.
  • An AC-coupled Enphase system can carry more component cost than a simpler DC-coupled package.

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