Our opinion
The buying view.
EDITORIAL OPINION - BASED ON THE CITED RESEARCH
“HS5 is now a real Australian comparison rather than a watch-list item. EK90's longer warranty is meaningful, but buyers should compare the throughput and internet-connectivity conditions as carefully as the headline 15 years.”
Best suited to
Homes wanting a high-capacity all-in-one system with phase-matched backup and a choice of warranty tier
What stands out
14–54 kWh approved configuration ladder, 63 A bypass, ≤10 ms switching and exact single- or three-phase inverter choices
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.
The smallest current approved combination is 14 kWh, so HS5 can be oversized for low-usage homes.
Full warranty coverage depends on internet monitoring and throughput limits; long outages can reduce the warranted period.
Whole-home backup still depends on the selected inverter, phase design, 63 A bypass setting and actual household loads.
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.
Specifications updated: HS5 now uses the exact current Australian EK70 and EK90 battery modules and 5/8/10 kW single-phase or 10/15/20 kW three-phase inverter listings. The approved capacity ladder starts at 14 kWh, and the separate 10-year EK70 and 15-year EK90 warranty conditions are disclosed.
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.
