| Certifications | SH5000-G3 and SH6000-G3 are Clean Energy Council approved inverters under EESS-240803-1, approved 12 March 2025, recorded with an inbuilt software client., The Pylontech US5000 and US5000-B modules are CEC-approved batteries, approved 14 January 2026, expiry 31 December 2027., Solar Victoria's inverter product list as of 27 July 2026 includes SH5000-G3 and SH6000-G3 under Redback Operations Pty Ltd. Synergy's Supported Solutions List, updated 30 July 2026, records both with provisional DER-Generator and DER-Storage status. | The current Australian approved-battery export lists SMILE-G3-BAT-9.3S and stacks through six modules to 31 December 2027; the exact system datasheet publishes IEC 62619 and AS/NZS 4777.2. |
| Warranty scope | Australia, with split exact-product obligations. Redback vD502 covers SH5000-G3, SH6000-G3 and SH-G3-BE for the earlier of ten years after installation or eleven years after manufacture. Pylontech separately covers US5000 module performance for ten years subject to its throughput and operating conditions. | The exact Australian datasheet publishes 10-year product and battery-performance warranties, governed by current AlphaESS Australia terms and Australian Consumer Law. |
| Warranty remedy | Redback may repair onsite or offsite or replace an accepted enclosure or inverter claim. Pylontech may repair or replace an accepted US5000 module claim. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | No unrestricted third-party labour or removal-and-reinstallation reimbursement is promised. No unrestricted removal and reinstallation entitlement is stated. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Pylontech states that it processes transport within Australia, but unconditional owner freight cover is not promised. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | Transfer is available at the original installation after new-owner registration. Relocation requires prior written approval. Compliant installation, cloud availability and the requested purchase, serial, installation and operating evidence are conditions. | Transfers automatically with the building while the system remains installed; ownership evidence may be required. Initial serial registration and eligible installation are required. |
| Grid compatibility | Single-phase 230 V system listed against AS/NZS 4777.2:2020. Redback publishes dynamic-export commissioning guides for SA Power Networks, Energy Queensland and the Victorian emergency backstop. Final network and installer approval remain project-specific. | The exact S5 configuration is a 230 V single-phase hybrid system with 5 kVA backup and AS/NZS 4777.2 grid regulation; final DNSP approval remains installation-specific. |

| Review note | The exact G3 reference remains SH-G3-BE with two to four Pylontech US5000 modules and an SH5000-G3 or SH6000-G3 inverter. It is separate from the RED-P1 Hybrid Battery Max family. The regulator lists the exact battery and inverter components in their respective categories; SH-G3-BE is not represented as a listed battery model. Warranty responsibility is split between the Redback and Pylontech instruments. | The exact 9.3 kWh battery module and supported stacks are current Australian approved-battery entries. |
| Register: parts term | stated: The SH-G3-BE, SH5000-G3 and SH6000-G3 are covered until the earlier of ten years after installation or eleven years after manufacture. Network adapters and meters are limited to two years. | stated: Ten-year product warranty for the named SMILE-G3-S5 system when installed on or after 1 November 2024. |
| Register: labour and service | conditional: Redback may provide onsite or offsite repair or replacement for an accepted claim. No unrestricted third-party labour or removal-and-reinstallation reimbursement is promised. | excluded: Normal maintenance, installer costs, travel and accommodation for on-site support are excluded. No general site-labour reimbursement is promised. |
| Register: transport and freight | conditional: Pylontech states that it processes transport within Australia for an accepted module claim, but the two instruments do not promise unconditional owner freight, removal or reinstallation cover. | conditional: Replacement parts and freight are included for valid claims, but other transport, travel and accommodation costs are excluded and reimbursement requires documentary evidence. |
| Register: registration | conditional: The Redback instrument requires compliant installation and cloud availability under its conditions. Module claims require purchase, serial, installation and operating evidence. | conditional: Installation requires an SAA-accredited installer with a valid Alpha Installer ID, and the serial number must be registered before a warranty claim. |
| Register: transferability | conditional: Coverage may transfer to a new owner at the original installation after registration. Relocation requires Redback's prior written approval. | stated: The warranty transfers to a subsequent purchaser of the building or products while the products remain installed and all warranty conditions continue to be met. |

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