Market position
The data
Hybrid inverter
Manages PV, battery DC and household AC through the inverter platform.

Warranty coverage: 10-year term
Coverage includes
Parts only · term longer than 24 of 95 scored inverters
No inverter in the fleet publishes a year-by-year performance or output guarantee the way panels and batteries do - this shows the covered term against the market-typical term and where every scored inverter’s term lands (grey dots, sized by model count), plus what the warranty actually includes.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score is anchored to the highest published rating in this exact series. Scored model: SUN-5K-SG03LP1-AU · checked 2026-06-19. Evidence.

Strong evidence coverage
26 of 26 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them.

AU Warranty scope
- Before
- Deye publishes Australian SUN-series warranty material, but legacy certificate and warranty evidence do not establish current SG03 supply.
- After
- Deye publishes an Australian and New Zealand SUN-series warranty (V2.17, library entry dated 17 September 2026), which states at page 6 that it applies to inverters with serial numbers 2311XXXXXX and later, effective 1 November 2023. Clause 1(1) refers to all SUN Series AU Type Hybrid Inverters, but the page 2 model tables of V2.10, V2.16 and V2.17 do not list SG03LP1, so the ten-year term is a series-level reading, conditional on the unit serial number, and is not model-named for this product. Legacy certificate and warranty evidence do not establish current SG03 supply.

Summary
- Before
- Not previously recorded
- After
- The SUN-5K-SG03LP1-AU datasheet specifies 7.5 kW maximum DC input for the 5 kW reference, a 1.5 array-to-rated-AC ratio. This is an array input limit, not 7.5 kW delivered AC; voltage, MPPT current, string and installation limits still apply. This technical correction does not establish current Australian approval or supply.
