A unit certificate is a document showing that a device model was tested and found compliant, and the full type test report holds the detailed test results behind it. Grid operators and system certifiers use these documents when they approve a system, and some ask for the full device test report on top of the unit certificate. Manufacturers such as SMA post unit certificates in their download areas, where you can find them by product family and document type. For PV system certification, the power-generating unit protection test is part of the certificate for existing systems and part of the declaration of conformity for new systems, so the test procedure must be fully documented. As-built documentation for a plant should include type test reports for equipment such as MV/LV transformers, along with routine test reports and certificates. Module standards such as IEC 61646 cover design qualification and type approval of a module design.
