Deye warranty explained (AU / NZ)

Every Deye inverter, all-in-one system and battery Suncloud supplies in Australia and New Zealand carries a manufacturer’s warranty. This page summarises the terms in plain English — how long each product is covered, what the “5+5” split means, which components carry shorter cover, who’s eligible, which models to confirm with us, and how to lodge a claim.

This manufacturer’s warranty applies in addition to — and does not limit — your rights under the Australian Consumer Law (ACL) and the New Zealand Consumer Guarantees Act (CGA). Nothing on this page reduces those statutory rights.

SUN Series inverters: the 10-year 5+5 structure

Deye’s SUN Series inverters carry a 10-year warranty delivered in two phases. Under the current AU/NZ SUN Series policy (V2.17, July 2026) this one cumulative structure applies to every covered inverter — both hybrid and string models:

• Years 1–5 — parts and repair labour. Deye repairs or replaces a defective unit free of charge, covering all parts and the labour needed to repair it.
• Years 6–10 — parts-only. Deye continues to supply covered replacement parts or units free of charge, but the following are not covered in this phase:
  • The LCD display and the cooling fan components
  • Repair labour
  • Taxes and duties
• Not covered in either phase: the installer’s fees for installation and on-site inspection, and the labour to uninstall the faulty unit and reinstall the repaired or replacement one.
• Return freight: Deye pays to ship the repaired or replacement product back by non-expedited freight within Australia and New Zealand.

Both phases together make up an unbroken 10-year term — the cover never lapses, the scope simply narrows from year six.

In years 6–10, covered parts are still replaced under the warranty, except the LCD and cooling fan, and repair labour is not covered. In neither phase does the warranty cover the installer’s call-out, removal or refit.

Covered SUN Series families

The 10-year 5+5 warranty applies across the SUN Series families below. Full specifications are on each product page; the exact models and power ratings covered are listed in the warranty certificate.

Series	Type
G05 string (SUN-5K … 25K-G05-AU)	Three-phase on-grid PV string inverter
G04 and G02P1 string (SUN-5K / 6K-G04-AU, SUN-8K / 10K-G02P1-AU-AM2)	Single-phase on-grid PV string inverter
SG04LP1	Single-phase hybrid
SG05LP1 (SUN-3.6–10K-SG05LP1-AU-AM2-P)	Single-phase hybrid
SG02LP1	Single-phase hybrid
SG01LP1	Single-phase hybrid
SG04LP3	Three-phase hybrid
SG05LP3 (SUN-14/15/16/18/20K-SG05LP3-AU-SM2)	Three-phase LV hybrid
SG01HP3	Three-phase HV hybrid
SG01HP3 (C&I)	Three-phase commercial hybrid
SG02HP3 (C&I) (SUN-60/70/75/80K-SG02HP3-AU-EM6)	Three-phase commercial HV hybrid
PCS + MPPT + STS (SUN-100/125K-PCS01HP3-AU, SUN-MPPT-L01-AU-AM8, SUN-STS500L)	C&I power conversion, PV and transfer-switch modules (the PCS itself: 5 years standard, extendable, per Deye’s AU PCS brochure)

Page 1 of the V2.17 policy covers all SUN Series AU type hybrid and string inverters, plus the C&I PCS, MPPT and STS modules, and pages 2–3 list the covered models by name. For the 100/125 kW PCS itself, Deye’s newer AU PCS brochure (V1.0, 3 September 2026) prints “Standard 5 years, extendable warranty”, and that is the term Suncloud quotes; the brochure gives the STS 10 years.

All-in-one storage (AI-W5.1-B-ESS)

The all-in-one AI-W5.1-B-ESS combines an integrated inverter with stacked battery modules, and the two parts are covered by separate terms:

• Inverter portion — 10 years. Deye’s all-in-one inverter warranty (Ver1.0) gives the models it lists full cover for the whole 10-year term, including the LCD and cooling fan. It lists the 3.6, 5, 6, 7.6 and 8 kW single-phase and all five three-phase models. The AI-W5.1-7P1-AU-B and AI-W5.1-10P1-AU-B are not on that list; their 10 years come from the SUN Series AU/NZ policy (V2.17, July 2026), which lists all 12 AU all-in-one models (p. 3) and uses the 5+5 structure above, so years 6–10 exclude the LCD, fan and repair labour.
• Battery portion (AI-W5.1-B module) — 10-year performance warranty. The battery is warranted for 10 years to retain at least 70% state of health (SOH) or until it reaches its rated energy throughput of 16 MWh per module (per-stack figures below), whichever comes first (measured at 25 °C, consistent with the datasheet). The BMS is covered for 10 years; other battery accessories for 5 years. Cover is conditional on the battery being installed, operated and maintained per the user guide.

Deye’s AU battery warranty for the AI-W-B range (February 2026 revision, linked from the AI-W5.1-B page) sets the System Energy and Minimum Throughput Energy for each stack model:

Model	System Energy	Minimum Throughput Energy
AI-W5.1-B (one module)	5.12 kWh	16 MWh
AI-W10.2-B	10.2 kWh	32 MWh
AI-W15.3-B	15.3 kWh	48 MWh
AI-W20.4-B	20.4 kWh	64 MWh
AI-W25.6-B	25.6 kWh	80 MWh
AI-W30.7-B	30.7 kWh	96 MWh

Each stack’s throughput figure is 16 MWh for every 5.12 kWh module in it. Check the model on the certificate supplied with the system, and confirm anything unclear with Suncloud support.

Ancillary components

Accessories and services carry their own, shorter terms — separate from the inverter warranty:

Component	Term
Data logger (WiFi / LAN / 4G dongle)	5 years
CT / energy meter	2 years

The CT/meter term is two years, much shorter than the inverter’s ten, so a meter fault after year two falls outside the warranty. The wireless Smart TX and CT are covered separately: Deye’s AU datasheets for the SUN-SMART-TXU1 and SUN-SMART-CTU2-L (21 August 2026) each print a 5-year warranty.

Eligibility

• Applies to inverters with serial numbers starting 2311 and later (November 2023 production onward), per the current AU/NZ policy effective 01/11/2023.
• Cover runs from the date of purchase / installation shown on the certificate.

General exclusions apply as set out in the certificate — typically damage from incorrect installation, unauthorised modification or repair, misuse, insufficient ventilation, or external causes (lightning, overvoltage, storm, fire, and similar).

Making a warranty claim

Lodge all claims through Suncloud support — not directly with the manufacturer. Suncloud manages the claim end to end.

Have this ready:

• Product model and serial number
• Proof of purchase and installation date
• Site address
• A clear description of the fault, plus any fault / error code shown on the inverter or in DeyeCloud
• Photos or a short video of the fault or display, if available

Reporting a fault: contact Suncloud as soon as you notice a fault — the manufacturer’s terms ask for claims to be lodged promptly (within one month of the fault occurring), and prompt reporting helps us resolve claims faster. This is a guideline for smooth handling only; it does not limit your rights under the Australian Consumer Law or the New Zealand Consumer Guarantees Act, under which you may be entitled to a remedy for a major failure regardless of any manufacturer reporting window.

This is a plain-English summary of Deye’s SUN Series 10-year limited warranty for Australia and New Zealand (V2.17, July 2026), its all-in-one inverter warranty (Ver1.0), the battery documents linked from each product page, the AU EV charger brochure and the AU Smart TX and wireless CT datasheets. The exact terms, exclusions, covered models and start date that apply to your unit are set out in the current Deye warranty certificate supplied with that specific product. Always check the certificate, and confirm anything unclear with Suncloud support.
