What paperwork should you keep after replacing a solar inverter?

Why inverter changes matter

Replacing an inverter can alter yield, monitoring, and electrical safety sign-off. Buyers may ask whether the system remains certified and insured.

What to retain

Electrical sign-off: EIC or minor works certificate from a competent installer, plus test results where supplied.

Equipment identifiers: model and serial for the new inverter and any updated monitoring gateway.

Warranty: new inverter warranty terms and contact paths.

Feed-in or export evidence: if you receive feed-in tariffs or export payments, keep scheme correspondence showing the installation remains registered where required.

Attach clear scans to your Property Passport with the date of replacement.
