| Certifications | Sungrow's SBH100-400 datasheet lists CE, CEC, IEC 62619, IEC 62040, UN 38.3 and VDE 2510-50 for the exact SBH family. | 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; Sungrow Australia Group Pty Ltd provides ten years for the exact SBH family and 70% retained capacity. Daily self-consumption and backup have unlimited cycles; other or mixed applications use the model-specific throughput table. | The exact Australian datasheet publishes 10-year product and battery-performance warranties, governed by current AlphaESS Australia terms and Australian Consumer Law. |
| Warranty remedy | Repair, equivalent replacement or depreciated refund at Sungrow's option. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | A standard service rebate contributes to approved repair labour; travel, subsistence and full installation costs are excluded. No unconditional removal and reinstallation entitlement is stated beyond the standard service rebate. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Standard ground freight is covered up to AUD 200 for an approved claim. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | The warranty is limited to the original purchaser or supplied end user and is otherwise non-transferable. Portal registration is encouraged; iSolarCloud monitoring and complete performance data are material warranty 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 | The AU product page lists compatibility with Sungrow SHT, SHRS, and SHRS-20 hybrid inverter series. | 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. |
| Local product pathway | No separate local pathway recorded | No separate local pathway recorded |
| Buyer evidence | Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed. | Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed. |
| Safety notice | No model-specific notice recorded | No model-specific notice recorded |
| Review note | SBH150 is current on the CER battery export until 4 January 2027. The warranty requires iSolarCloud monitoring and performance data; incomplete data reduces the promised minimum term to four years. | The exact 9.3 kWh battery module and supported stacks are current Australian approved-battery entries. |

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.
A score lead is only meaningful inside this shared class or tier. Weigh it against the specification and evidence rows above before deciding.
Both products are scored in the Performance & Value class, on the same rubric weighting. Scores are not comparable across classes or tiers. Full methodology.
