2. Warranty Coverage

Eligible Marstek battery storage products are covered by a 10-year manufacturer warranty, subject to the manufacturer's official warranty conditions.

Warranty coverage may vary depending on:

• Product model

• Product category

• Installation environment

• Operating conditions

• Manufacturer warranty requirements

Manufacturer warranty coverage generally applies to manufacturing defects or product failures occurring under normal operating conditions and proper installation or use.

Marstek-EU acts as a reseller and warranty support facilitator.

E2C B.V. remains responsible for its statutory obligations as the seller, including legal product conformity rights.

3. Warranty Eligibility

Manufacturer warranty coverage may depend on whether products:

• Were purchased through an eligible sales channel

• Remain identifiable through valid serial numbers

• Have been installed correctly, where installation is required

• Have been installed and operated in accordance with manufacturer instructions

• Have been used under normal operating and environmental conditions

• Have not been modified, opened, or repaired in ways excluded by the manufacturer's warranty terms

Customers may be asked to provide:

• Proof of purchase

• Product serial number

• Installation information, where applicable

• Installer details, where relevant

• Photos or videos of the issue

• Error codes or monitoring screenshots

• Product monitoring logs, where applicable

Warranty eligibility may be affected where reasonably necessary supporting information cannot be provided.

Manufacturer warranty transferability is subject to the applicable manufacturer's terms.

These requirements do not automatically limit statutory consumer rights.

4. Installation Responsibility & Compliance

Battery storage systems and related electrical products must be installed, handled, operated, and maintained in accordance with manufacturer instructions and applicable local regulations.

Depending on the product, professional installation may be required or recommended.

Applicable requirements may include:

• Local electrical regulations

• Grid connection requirements

• Relevant safety standards

• Manufacturer installation manuals and operating instructions

Plug-and-play battery systems must be connected and operated in accordance with the manufacturer's instructions.

Customers should verify applicable local installation, electrical safety, and grid connection requirements.

High-voltage electrical installations must not be installed, modified, serviced, opened, or repaired by unqualified persons.

Improper installation, incorrect configuration, unauthorized modifications, or incompatible system integration may affect manufacturer warranty eligibility where permitted by the applicable warranty terms.

Statutory consumer rights remain unaffected.

5. Warranty Exclusions

Manufacturer warranty coverage may exclude defects or damage directly resulting from:

• Improper installation

• Unauthorized modifications or repairs

• Incorrect wiring or electrical configuration

• Incompatible products or system integration

• Physical damage, misuse, negligence, or abuse

• Flooding, corrosion, fire, lightning, or natural disasters

• Environmental conditions outside manufacturer specifications

• Improper ventilation, overheating, or freezing conditions

• Failure to follow manufacturer instructions

• Use outside intended product specifications

• Unauthorized software or firmware modifications

• Third-party accessory incompatibility

• Cosmetic wear and tear not affecting functionality

Products with removed, altered, or damaged serial number labels may require additional verification.

Exclusions apply only to the extent permitted by the applicable manufacturer warranty and relevant law.

Manufacturer warranty exclusions do not automatically remove statutory rights against E2C B.V. for products that do not conform to the purchase agreement.

6. Software, Firmware & Monitoring Platforms

Certain Marstek products may rely on:

• Software systems

• Firmware updates

• Monitoring platforms

• Mobile applications

• Cloud-based services

• Communication and monitoring accessories

Availability, compatibility, and functionality may depend on the manufacturer or third-party service providers.

Software, firmware, and monitoring functionality may change due to updates or service modifications.

E2C B.V. does not independently guarantee uninterrupted availability of third-party software or cloud services beyond its contractual and statutory obligations.

Where digital functionality or updates form part of the purchase agreement, applicable consumer conformity rights remain unaffected.

7. Dead on Arrival (DOA) & Delivery Inspection

Products arriving damaged, defective, incomplete, or visibly affected during transport should be reported to Marstek-EU customer support as soon as reasonably possible.

Customers may be asked to provide:

• Photos of packaging

• Photos of products

• Shipping labels

• Delivery documentation

• Description of the issue

Reporting visible delivery problems within 48 hours is recommended to help investigate transport damage.

Failure to report a defect or delivery issue within 48 hours does not automatically invalidate statutory consumer rights.

Consumers retain their applicable rights concerning defective or non-conforming products.

Manufacturer approval is not a prerequisite for exercising statutory rights against the seller.

10. Shipping & Transport Costs

Lithium battery products may require specialized transport arrangements under applicable transport regulations.

Customers must follow appropriate safety, packaging, labeling, and transport instructions when returning battery products.

Damaged, leaking, swollen, or otherwise unsafe lithium batteries must not be shipped through ordinary parcel services without appropriate authorization and safety arrangements.

For valid statutory consumer conformity claims, legally required remedies must be provided free of charge, including necessary transport costs.
