Our opinion

The buying view.

EDITORIAL OPINION - BASED ON THE CITED RESEARCH
“The IP20 rack requires an indoor location. Ask for the exact Australian inverter model, written compatibility and an installed price.”

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 documented rack requires a high-voltage inverter. Sunsynk’s low-voltage L5.3 inverter range is unsuitable.
  • The battery-side rating alone cannot establish inverter output or blackout capability.

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