Sweden is preparing to replace its existing list of pre-assessed solar and battery inverters with a new digital database in 2027, according to Swedish energy industry association Energiföretagen Sverige.

The new system, called Rikta Rätt 2.0, will provide standardized technical information on inverters used in solar photovoltaic and battery energy storage installations, helping electricity distribution system operators (DSOs) assess grid connection applications.

“The basic requirements for inclusion in the new database will be limited to contact information, manufacturer name and type designation. However, inclusion will not constitute an approval or demonstrate compliance with technical requirements,” a spokesperson for Energiföretagen Sverige told pv magazine. “The database will provide relevant technical information and supporting documentation for each model. Manufacturers must provide supporting documentation where required, for example certificates when claiming conformity with a particular standard.”

Rikta Rätt 2.0 will not require additional product testing solely for inclusion in the database. Technical information will generally be supported by certificates, test reports and other documentation from existing testing and conformity assessment procedures.

“The approach is similar to the current Rikta Rätt process, but more transparent: the database will show technical information and supporting documentation on which the network operator can base its assessment.,” the spokesperson added. “The categories and associated requirements are still being finalized, but the documentation requirements are expected to remain close to those applied in the current Rikta Rätt.”

Inverter models already included in the current Rikta Rätt list will remain on the PDF version of the list . The CSV version will be removed from the Energiföretagen Sverige’s website at the end of 2027.
