Our opinion
The buying view.
EDITORIAL OPINION - BASED ON THE CITED RESEARCH
“HS5 is the SAJ system to watch, but it should not be compared as a normally available approved product yet. Treat quotes as expressions of interest until the exact EK70 model appears on the current Australian approvals and warranty documents.”
Best suited to
Early-stage planning for a high-capacity all-in-one system with strong backup and smart-home ambitions
What stands out
6–54 kWh AU launch ladder, 63 A bypass, ≤10 ms switching, built-in DC/DC optimisation and up to four MPPTs
03
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.
Australian CEC approval and final market availability are still pending.
The global HS5 page describes a broader platform than the supplied Australian single-phase launch datasheet, so global claims may not apply to the AU configuration.
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.
Australian launch: The supplied 5–10 kW single-phase launch range and 6–54 kWh battery configurations are now compared with an explicit CEC approval-pending warning.
