| Certifications | The current BCU V2.0 HVS datasheet lists VDE 2510-50, IEC 62619, CEC, CE and UN 38.3 for the exact family. | Sungrow's SBH100-400 datasheet lists CE, CEC, IEC 62619, IEC 62040, UN 38.3 and VDE 2510-50 for the exact SBH family. |
| Warranty scope | Australia; the current BCU V2.0 warranty names HVS 10.2, provides a 10-year product term and 70% retained usable energy or 30.82 MWh, whichever performance limit occurs first, for products purchased and installed on or after 1 November 2024. | 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. |
| Warranty remedy | Shenzhen BYD Electronics Co., Ltd. may repair, replace with an equivalent new or previously used part, or provide a partial refund. | Repair, equivalent replacement or depreciated refund at Sungrow's option. |
| Labour and reinstallation | The warranty does not promise independent installation labour, travel, removal or reinstallation reimbursement. Removal and reinstallation are not promised. | 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. |
| Freight | Ordinary claim freight is not an unconditional entitlement. BYD pays reasonable disposal cost only when it requires disposal of a replaced item. | Standard ground freight is covered up to AUD 200 for an approved claim. |
| Transfer and registration | Coverage extends to a subsequent owner who acquires the installed product for their own use and provides proof of ownership. Invoice and system details are required, defects must be notified within 30 days, and performance data must be made available over the internet on request after a claim. | 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. |
| Grid compatibility | The Australian HVS/HVM datasheet identifies on-grid, on-grid plus backup and off-grid applications, and requires a compatible inverter from BYD's current HVS/HVM compatible-inverter list. Final inverter listing and DNSP approval remain site-specific. | The AU product page lists compatibility with Sungrow SHT, SHRS, and SHRS-20 hybrid inverter series. |
| 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. |

| Review note | The exact HVS approval remains current until 19 October 2026. The separately listed HVM+ family is not treated as an extension, rename or successor to this HVS record. Shenzhen BYD Electronics Co., Ltd. is the warranty provider and Alps Power Pty Ltd is the Australian service partner. | 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. |

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.
