IEC 62093:2022 pdf download,Photovoltaic system power conversion equipment – Design qualification and type approval.
IEC 62093 lays down IEC requirements for the design qualification of power conversion equipment(PCE)suitable for long-term operation in terrestrial photovoltaic (PV)systems.
This document covers electronic power conversion equipment intended for use in terrestrial PV applications.The term PCE refers to equipment and components for electronic power conversion of electric power into another kind of electric power with respect to voltage,current,and frequency.This document is suitable for PCE for use in both indoor and outdoor climates as defined in IEC 60721-3-3 and IEC 60721-3-4.Such equipment may include,but is not limited to,grid-tied and off-grid DC-to-AC PCEs,DC-to-DC converters,battery charger converters,and battery charge controllers.
IEC 62093 covers PCE that is connected to PV arrays that do not nominally exceed a maximum circuit voltage of 1 500 V DC.The equipment may also be connected to systems not exceeding 1 000 V AC at the AC mains circuits,non-main AC load circuits,and to other DC source or load circuits such as batteries.If particular ancillary parts whereby manufacturers and models are specified in the manual for use with the PCE,then those parts are tested with the PCE.
