IEC 62109-3-2020 pdf free download – Safety of power converters for use in photovoltaic power systems – Part 3: Particular requirements for electronic devices in combination with photovoltaic elements.
This Part 3 of lEC 62109 covers the particular safety requirements for electronic elements thatare mechanically and/or electrically incorporated with photovoltaic (PV) modules or systems.
Mechanically and/or electrically incorporated means that the whole combination of electronicdevice with the photovoltaic element is sold as one product. Nevertheless, tests provided in this
document may also be used to evaluate compatibility of PV modules and electronic devices thatare sold separately and are intended to be installed close to each other.
ltems included in the scope:
Electronic devices combined with PV modules that perform functions such as, but not limitedto，DC-DC or DC-AC power conversion，active diodes，protection，control,monitoring, orcommunication. These requirements specifically address such electronic devices used incombination with flat-plate photovoltaic (Pv) modules.
NOTElt is acknowledged that the physical design of products covered by this scope may vary widely， it isanticipated that the requirements of this document may need to evoive to meet the unique sarety requirements ofsuch products，particularly if the photovoltaic element of the product is not of a flat-plate configuration. As anexample, this document does not fully address the safety requirements of building-integrated photovoltaics (BIPV)and building-ttached photovoltaics (BAPV) products，although they would fall under the scope’of this document.The purpose of the requirements of this part of lEC 62109 is to provide additional safety-relatedtesting requirements for the following types of integrated electronics, collectively referred to asmodule integrated equipment (MIE):
a) Type A MlE where the PV element can be evaluated as a PV module according toIEC 61730-1 and lEC 61730-2 independently from the electronic element;
b) Type B MlE where the PV element cannot be evaluated as a PV module according toIEC 61730-1 and IEC 61730-2 independently from the electronic element.
ltems excluded from the scope:
PV modules with only one or more bypass diodes as the combined or integrated element. Suchproducts are covered by lEC 61730-1 and lEC 61730-2.
Aspects included and excluded from scope:
All aspects of IEC 62109-1:2010 apply. Addition to the list“excluded from the scope”isevaluating the MIE to lEC 61215-1.
