The ENA Type Test Register lists grid-connection devices such as inverters, and gives each one a UK ENA reference number. The register has moved to the Energy Networks Association connect website, and the old site no longer gets updates. To find a device, open the Live Device Register, use the filters to narrow the search, usually by model, and then open a reference to see what it covers. Depending on when a device was registered, it may have a separate reference number for G100, while some newer devices have several certifications under one reference. Any device above 50kW must now go through as Partially Type Tested, whatever the brand. For these larger units, voltage flicker and harmonics are assessed site by site, often through a witness test or an A2-3 form, so the installer should agree the process with the DNO. Older devices stay listed as Fully Type Tested, unchanged from earlier applications, which can confuse DNOs and installers.
