What evidence helps an inverter warranty claim?

A clear warranty file helps the service team assess a fault and submit the appropriate information. The aim is to identify the equipment, describe the problem accurately and preserve the relevant history. A warranty request is not the same as an approved replacement. The applicable terms and the manufacturer’s assessment determine the outcome.

Evidence for an Inverter Warranty Claim

What you will see

A request for an inverter model and serial number.
Missing proof of purchase or commissioning date.
A fault reported without its complete alarm code.
Uncertainty about earlier repairs or equipment replacement.

Why it happens

Solis’s replacement procedure includes fault registration, technical assessment and verification of applicable warranty coverage. It recommends qualified installers for inspection and replacement work.

Prepare the invoice, installation date, serial record, exact warning and service history. Include when the issue began and whether it followed a supply event, building work or another equipment change.

If the manufacturer’s process requests further tests, those should be performed by an appropriately qualified person. Customers should not open an inverter to obtain internal photographs or measurements.

Solis’s replacement procedure. Applies to Solis, GoodWe, Growatt and Huawei inverters.

What you can check yourself

Locate purchase and commissioning documents.
Save normal user-screen alarms and event history.
Gather previous support references and repair reports.
Photograph an externally visible identification label only if safely accessible.
Where a record is missing, explain the gap. Do not guess a commissioning date or copy a serial from a similar unit.

What not to do

Do not remove seals, attempt internal repairs or send equipment to an unverified destination. Do not assume that warranty approval covers every visit, transport or installation cost without checking the actual terms.
