Our opinion

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.

  • Battery output and backup behaviour depend on the paired Growatt inverter and optional backup hardware.
  • Larger systems need their tower, module and parallel-expansion limits confirmed against the exact model.

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