Scope: This standard applies to grid-interconnected photovoltaic (PV) power generation systems that operate in parallel with the grid and use static (semiconductor) non-islanding inverters that convert DC to AC. This standard describes relevant recommendations for systems with a rated power of 10 kVA or less, such as single-phase or three-phase systems for detached dwellings. This standard applies to the interconnection of low-voltage grid distribution systems. The purpose of this standard is to specify the requirements for the interconnection of photovoltaic systems with grid distribution systems. This standard does not address protection mechanisms against electromagnetic compatibility or islanding.
