CertificationsSOFAR's exact PowerAll system documentation lists IEC 62619 and UN 38.3 for the BTS 5K battery, alongside inverter safety and Australian grid standards.The exact Australian SMILE-G3-S5/B5 + BAT-9.3S datasheet lists AS/NZS 4777.2 grid regulation, IEC 62109 and IEC 62040 safety standards, IEC 61000 EMC, and IEC 62619 for the battery module.
Warranty scopeSOFAR's Australian battery warranty names BTS 5K and provides 10 years or 18.25 MWh with 70% retained usable energy, whichever occurs first. The warranty table uses a 4.60 kWh usable-energy reference while the January 2026 datasheet publishes 4.992 kWh usable capacity.The exact Australian datasheet lists a 10-year product warranty and 10-year battery-performance warranty for SMILE-G3-S5/B5 with BAT-9.3S. Alpha ESS Australia's current residential warranty terms name the SMILE-G3-S5 system, apply to installations from 1 November 2024, and are additional to Australian Consumer Law rights.

Australia purchase checks

Make the shortlist quote-ready

These checks sit beside the benchmark score. They are site, tariff and contract questions that no product score can settle.

  1. Lock the exact model and installation-date listing.

    Ask for every model number to appear on the quote and order. The Clean Energy Council product lists are live: STC creation requires listed products at installation, and network requirements may also depend on current approval.

  2. Obtain the site-specific connection settings.

    Have the retailer state the supply phase, inverter connection limit, export limit and any export-control cost. The local network connection agreement, not a generic datasheet, determines those settings. See the Australian Government's connection guidance.

  3. Test savings against the household, not a brochure.

    Ask which bills or interval data, tariff, feed-in rate, export limit and future loads support the savings and payback claim. Self-consumed electricity and tariff timing usually matter more than a headline feed-in rate. See the system sizing and battery savings guidance.

  4. Specify the operating outcome.

    Define the usable energy, output power, backed-up circuits and outage behaviour. Confirm whether VPP participation, an internet connection, or an additional controller changes the configuration, reserve level, warranty or support path.

  5. Name the party responsible after installation.

    Keep the retailer, installer, manufacturer warranty and escalation path in the contract. Australian Consumer Law guarantees apply separately from any manufacturer warranty; where one business supplied both product and installation, it is generally responsible for the remedy. See the ACCC guidance.
