Our opinion

The buying view.

EDITORIAL OPINION - BASED ON THE CITED RESEARCH
“The individual models are listed as single-phase. GoodWe also describes retrofits alongside existing three-phase solar. Ask the installer to specify metering, connections and backup by phase.”
Best suited to
Retrofitting a compatible low-voltage battery while retaining an existing PV inverter
What stands out
Three listed battery-only inverters with 75 A or 120 A battery ports

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 SBP G2 has no PV input. The existing or separate PV inverter remains part of the design.
  • A three-phase PV retrofit does not establish three-phase blackout backup.

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