Our opinion

The buying view.

EDITORIAL OPINION - BASED ON THE CITED RESEARCH
“H2 is the essential counterpart to the B2 and B2S batteries. Its unusually broad power range makes model-level comparison mandatory: a 5 kW single-phase H2 and a 20 kW three-phase H2 are not equivalent proposals.”
Best suited to
SAJ B2 and B2S battery systems where phase and output are selected together
What stands out
Twenty-one current CEC model entries cover both phases and residential output from 3 to 30 kW

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 family name covers materially different single- and three-phase models.
  • Battery stack, backup output, generator or smart-load functions and network export settings must be verified against the exact H2 suffix.

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