The assessed Low voltage ride through performance is valid only for the specific configuration and operational mode of the inverter under test. Separate assessment is required for the inverter in othe factory or user-settable configurations, as these may cause the inverter Low voltage ride through response to behave differently.The measurement procedures are designed to be as non-site-specific as possible, so that Low voltage ride through characteristics measured at one test site, for example, can also be considered valid at other sites.This technical specification is for testing of PV inverters, though it contains information that may also be useful for testing a complete PV power plant consisting of multiple inverters connected at a single point to the utility grid. It further provides a basis for utility-interconnected PV inverter numerical simulation and model validation.
