Stäubli MC4 Connector Pair

Stäubli Warranty Policy

This warranty policy applies to Stäubli MC4 connector products and Stäubli MC4 assembly toolsets supplied by us in Australia through authorised sales channels. This policy applies to the original end-user purchaser of the product, as evidenced by our invoice or an authorised reseller’s invoice, and is not transferable without written consent.

Stäubli products supplied by us are warranted to be free from defects in materials and workmanship under normal use and service, subject to the terms and conditions below. The benefits given by this warranty are in addition to any other rights and remedies available under law.

Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.

Warranty Coverage and Periods

This warranty covers Stäubli MC4 connector products and MC4 assembly tools supplied by us, including the product ranges listed below.

Commencement of Warranty: The warranty period begins on the date of purchase by the original end-user, as shown on our invoice or the authorised reseller’s invoice. A valid proof of purchase from an authorised sales channel is required for all warranty claims.

Installer Responsibilities and System Design

Stäubli MC4 connector products are electrical components intended to be assembled, connected, and installed as part of a photovoltaic electrical system. Once installed, the product forms only one component of a broader system. The installer, system designer, contractor, dealer, or end-user is responsible for ensuring that the product is suitable for the intended application and is installed correctly.

Stäubli MC4 connectors and related products must be installed in accordance with the relevant Stäubli assembly instructions, product manuals, ratings, cable compatibility requirements, applicable Australian Standards, electrical safety rules, and recognised solar industry best practice.

Issues or damage arising from incorrect installation, poor system design, incorrect cable selection, incorrect crimping, incomplete engagement, incompatible mating connectors, incorrect polarity, inadequate strain relief, incorrect cable routing, excessive mechanical stress, or failure to follow instructions are not product defects and are not covered by this warranty.

• Approved tools and assembly: MC4 and MC4-Evo connector products must be assembled using suitable Stäubli-approved tools and methods for the relevant connector range. Incorrect crimping, stripping, tightening, unlocking, or reassembly may void warranty coverage.
• System compatibility: The installer is responsible for using compatible PV cable, mating connectors, branch connectors, inverters, optimisers, combiner boxes, isolators, and other connected equipment. Damage caused by incompatible or incorrectly rated components is not covered.
• Electrical protection: The installer must ensure the system includes appropriate protection, isolation, polarity control, over-current protection, and fault isolation required for the installation.
• Environmental suitability: Products must be installed within their specified environmental ratings and protected from contamination, water ingress beyond rating, chemical exposure, UV exposure beyond specification, excessive heat, excessive vibration, mechanical strain, and corrosion risk.
• Service accessibility: Products must be installed in a way that allows reasonable access for inspection, testing, servicing, removal, and replacement.

We may require installation evidence when assessing a warranty claim. This may include photos of the product before removal, cable type, connector model, crimp photos, tool details, system layout, electrical test results, serial or batch identification where applicable, and installer details.

Warranty Exclusions

This warranty covers manufacturing defects or failures of the Stäubli product supplied by us arising from normal use in accordance with the applicable instructions. It does not cover failure, damage, performance issues, deterioration, or loss caused wholly or partly by external factors, misuse, incorrect installation, or circumstances outside the control of the product itself.

• Improper installation or handling: Damage caused by incorrect assembly, incorrect cable stripping, incorrect crimping, incorrect tightening, incorrect unlocking tools, incorrect mating, reverse polarity, poor cable routing, excessive pulling force, inadequate strain relief, damage during removal, or failure to follow Stäubli instructions is not covered.
• Use of incompatible components: Damage or failure caused by mating with non-compatible connectors, counterfeit connectors, incorrectly rated cable, unsuitable PV cable, incompatible inverter inputs, unsuitable branch connectors, or other third-party components is not covered.
• Misuse, abuse, or neglect: This warranty does not cover physical abuse, impact, crushing, dropping, bending beyond specification, contamination, continued use after visible damage, use outside ratings, or use for purposes other than the intended PV electrical application.
• Unauthorised modification or repair: Any modification, disassembly, alteration, unauthorised repair, re-crimping, reuse of single-use parts, tampering with contacts, or replacement with non-original parts may void warranty coverage.
• Environmental damage: This warranty does not cover damage caused by water ingress beyond product rating, corrosion, salt mist beyond specification, chemical exposure, excessive dust, mud, debris, pest damage, fire, smoke, lightning, flood, storm, hail, excessive heat, excessive cold, UV exposure beyond specification, or improper storage.
• System design faults: Failures caused by over-voltage, over-current, arcing caused by poor system design, incorrect string design, incompatible connected equipment, insufficient protection devices, cascading faults, or incorrect isolation are excluded.
• Normal wear and consumable wear: Normal wear and tear is not a defect. For toolsets, this includes normal wear of jaws, dies, blades, cutting edges, locators, adjustment mechanisms, calibration, handles, cases, and other tool components unless the failure is caused by a manufacturing defect.
• Serial, batch, or identification marking removed: Where applicable, product identification, batch markings, rating labels, or tool identification must remain intact and legible. Removal, defacement, or alteration may make the product ineligible for warranty service.
• Unauthorised resale or non-authorised purchases: This warranty applies only to genuine new Stäubli products supplied by us or through an authorised sales channel. Products purchased second-hand, from unauthorised marketplaces, liquidation sales, grey-market sellers, or unapproved channels may not be covered.
• Commercial, industrial, or abnormal applications: Unless approved in writing, this warranty applies to normal recommended photovoltaic applications. Use in abnormal, high-stress, experimental, modified, or non-compliant systems may be excluded.
• Other exclusions: This warranty does not cover accident, collision, vandalism, theft, force majeure events, transport damage after delivery, or consequential losses such as labour, removal, reinstallation, lost generation, downtime, access equipment, travel, freight not approved by us, or damage to other equipment to the extent permitted by law.

Making a Warranty Claim

Important: If you suspect a fault with a Stäubli MC4 connector product or MC4 toolset supplied by us, do not immediately remove, cut off, disassemble, or modify the product unless it is unsafe to leave it in place or unless authorised by us or the authorised reseller. Premature removal or alteration can prevent proper assessment and may affect warranty eligibility.

1. Contact the place of purchase: Warranty claims should be initiated through the authorised dealer, reseller, distributor, or place of purchase.
2. Provide product information: Provide proof of purchase, product model, batch or serial number where applicable, installation date if known, description of the issue, and photos or videos showing the fault.
3. Provide installation or use evidence: For connectors, provide photos of the product in its installed location before removal, cable markings, crimp condition, mating connector details, and relevant system information. For toolsets, provide photos of the tool, die, locator, jaw, or damaged component and a description of how the tool was being used.
4. Assessment and troubleshooting: We, the reseller, or the supplier may request safe checks, measurements, installation details, tool details, or return of the product for inspection.
5. Return for inspection: If required, the product must be securely packaged and returned to the nominated assessment location. Transit damage caused by poor packaging is not covered.
6. Evaluation and outcome: Once assessed, the claim will be accepted if the fault is confirmed to be a covered manufacturing defect. If the product is not faulty or the issue is caused by an excluded factor, the claim may be rejected.

Remedies Under Warranty

If a defect covered by this warranty is confirmed, we may provide an appropriate remedy, which may include repair, replacement, refund, credit, supply of replacement parts, or another remedy required by law.

Repair: If the defect can be resolved by repair, the product or relevant component may be repaired by an approved party.

Replacement: If the product is not reasonably repairable, a replacement may be supplied. The replacement may be the same model, a superseded equivalent, or a product with similar specifications. Where a replacement is provided, the faulty product becomes the property of the supplier unless otherwise agreed.

Refund or credit: In some cases, a refund or credit may be provided. Refunds will usually be handled by the original place of purchase and will not exceed the original purchase price paid for the affected product unless otherwise required by law.

No charge for approved claims: For approved warranty claims, the approved remedy will be provided at no charge to the customer. Reasonable return freight may be covered where required by law or where expressly approved in advance.

No extension of original warranty: Repair or replacement under this warranty does not restart or extend the original warranty period. The warranty continues from the original purchase date.

Limit of Liability

To the extent permitted by law, liability under this warranty is limited to the repair, replacement, refund, credit, or approved remedy relating to the defective Stäubli product supplied by us.
