Sunsynk has moved warranty registration for its products onto a new system, replacing the old warranty form. The company states that registrations made using the old form on or before 24 April 2024 may not be searchable on the new system1.
The new registration form is for UK installations only, and Sunsynk asks that the MCS certificate number is ready before the form is completed1. The form collects installer details, property owner details, equipment information and purchase information. Equipment type is selected from Sunsynk Inverter, Lifelynk / Powerlynk, Sunsynk Battery, Sunsynk Inverter + Sunsynk Battery, Lynks Inverter, Lifelynk / Powerlynk + Sunsynk Battery, or Other1. Inverter quantity can be entered from 1 to 10, and battery quantity from 1 to 161.
Required uploads include a clear photo of the completed installation and proof of purchase, described as a receipt, invoice or proof of purchase document1. A Certificate of Compliance upload field is also listed, and the form states that incomplete or inaccurate information may lead to the rejection of a warranty claim1.
"If you've previously registered using the old warranty form on or before 24/04/2024, your information may not be searchable on the new system."
Existing registrations can be searched by warranty number or installer email address1. Sunsynk directs anyone wishing to modify or update a registration to customerservices@sunsynk.com1. The company's UK office is given as Unit 8, Total Park, Bennetts Lane, Shell Green, Widnes WA8 0GW, telephone +44 151 832 43001.

Why it matters for households
A warranty is only useful if the registration behind it can be found when a claim is made. For a household with solar panels, an inverter or a battery, the registration record is the link between the equipment in the home and the manufacturer's obligation to repair or replace it. If a registration made on the old form cannot be found on the new system, the paperwork held at home becomes the main evidence that cover was taken out, which is why the warranty registration record and the documents behind it matter beyond the day of installation.
The change is specific to Sunsynk, so households with that make of equipment are the ones affected. The position for other manufacturers has not been reported here. For Sunsynk owners, the practical points are the date of the original registration, whether the MCS certificate number and proof of purchase are still to hand, and whether the installation photo taken at the time still exists. The company has not said that old registrations are invalid, only that they may not be searchable, and it has not stated what evidence it will accept in place of a search result. Households whose installer handled the registration may need to check what was submitted and when, since the installer email address is one of the two search keys. The Sunsynk warranty registration process is the route for checking or updating a record, and the workmanship warranties and aftercare arrangements sit alongside the manufacturer's cover rather than replacing it.
What happens next
No deadline for re-registering or for contacting Sunsynk about an old registration has been reported. The company's stated route for modifying or updating a registration is email to customerservices@sunsynk.com1. No end date for the old form, and no statement on whether old records will be migrated, has been published1.
