HOW TO MAKE A CLAIM UNDER THE GOODWE LIMITED WARRANTY

To make a warranty claim, please contact your local distributor or installer. If you are unable to obtain satisfactory service, you can escalate your request by creating a service ticket via https://goodwetechnology.zendesk.com/hc/en-gb. GOODWE cooperates with distributors and installers worldwide to provide timely service.

Please have the following information ready when contacting a service channel:

1. Claimant contact information (name, company, phone, email, address).
2. Defective system information (model No., serial number, installation date, failure date). Claims must be made within one month of failure.
3. Installation information (PV panel brand, model, number).
4. APP error message (if applicable) and fault details.
5. Description of actions before failure and previous claim information (if applicable).

GOODWE may arrange an on-site inspection. The claimant is responsible for providing access, time, and ensuring safety during the inspection. GOODWE technicians reserve the right to refuse entry if the site is deemed unsafe.

REMEDY

If a claim is valid, GOODWE may, at its discretion:

1. Fix the issue by changing configurations or updating software.
2. Repair the Energy Storage system by replacing with spare parts.
3. Exchange the Energy Storage system for a new, refurbished, or upgraded model. If replaced, the remaining warranty period transfers to the new unit, with a minimum 6-month extension if the remaining period is less than half a year. An RMA report must be submitted for replacement cases.
4. If a fault is proven to be caused by faulty installation, GOODWE may require the original installer to provide a solution before intervention, and may charge the installer for costs if they fail to do so.
5. All replaced parts become GOODWE's property. A handling fee may be charged for units not covered by the warranty.

WHAT IS COVERED AND NOT COVERED?

GOODWE's limited warranty covers the cost of hardware material required to get the device functioning again. Transportation costs may be covered by GOODWE using normal ground transportation up to a specified amount; excess costs or costs for alternative transportation methods are the claimant's responsibility. If the allegedly defective Energy Storage system is not returned within 4 weeks of receiving a replacement, or if no damage is found, GOODWE will invoice the claimant for the replacement unit and associated charges.

On-site service labor costs may be covered by a rebate offered by GOODWE at its sole discretion, under specific conditions:

• The rebate is only for the party performing the on-site service.
• The defective Energy Storage system must have been returned and found to have workmanship or material defects upon testing.
• GOODWE must authorize the site visit prior to service.
• The service rebate must be claimed within 2 months of the authorized site visit date.
• The total labor cost covered (including TAX/GST) is capped at a specified amount per case.

GOODWE's limited warranty does not cover costs related to direct or indirect damages, loss of profit, loss of use, business interruption, increased costs, or any indirect, consequential, special, or punitive damages. Liability is limited to the purchase value of the Energy Storage system, except in cases of gross negligence, intentional misconduct, death, or personal injury resulting from GOODWE's proven negligence.
