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 complete price before rebates remains quote-only.
  • Confirm the exact inverter, firmware, parallel design and backed-up circuits.

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