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.

  • Quote Checker can also assess like-size 6 or 9 kWh models. Mixed stacks and parallel columns require an installer’s module schedule.
  • Grid AC output, continuous backup and battery output are separate limits. Ask for the backed-up circuits and sustained output per phase in the quote.

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