CEC status checked
Eight H2 battery configurations, including the Australian-suffixed 5.3–26.5 kWh models, are CEC-listed to 31 December 2027. Current HYXi HS and HT hybrid inverters provide separately listed single- and three-phase routes.
Standout specification
Official product data identifies 5–50 kWh usable configurations, with current Australian CEC entries for all eight exact model codes

These model names sit inside the family above. Capacity, phase and output still need to match the installed configuration.

Our opinion
The buying view.
EDITORIAL OPINION - BASED ON THE CITED RESEARCH
“H2 is the HYXi generation to compare for larger homes. Its wide ladder is useful, but a 50 kWh battery stack does not automatically justify a large inverter or guarantee every circuit will be backed up.”
Best suited to
Larger modular HYXi installations needing current Australian H2 hardware and phase-specific hybrid inverters
What stands out

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 Australian CEC register reports nominal model capacities up to 53 kWh while the manufacturer datasheet states 5–50 kWh usable; the finder uses the lower usable figures.
HYXi describes a broad high-voltage interface, but the catalogue only credits the specifically evidenced HS and HT inverter routes until an exact third-party compatibility document is supplied.
Ask for these points to be answered against the exact model numbers and installed configuration in your quote.

Evidence trail
Check the sources.
Specifications can change by model revision, region and paired hardware. CEC approval is not proof of current availability or suitability. Confirm the model and final design with the manufacturer and an accredited Australian installer.
New product: The newer H2 high-voltage battery family is now compared alongside the original H generation, using the manufacturer's lower 5–50 kWh usable figures and exact Australian CEC model codes.
