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.

  • It is three-phase only.
  • The exact battery tower count, XHUB or metering accessories and backup output need to be itemised.

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