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 CSA-C22.2 No. 62109 covers the particular safety requirements for electronic elements that are 
mechanically and/or electrically incorporated with photovoltaic (PV) modules or systems. Mechanically and/or 
electrically incorporated means that the whole combination of electronic device 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 that are sold separately and are intended to be installed 
close to each other. 

Items included in the scope: 

Electronic devices combined with PV modules that perform functions such as, but not limited to, DC-DC or 
DC-AC power conversion, active diodes, protection, control, monitoring, or communication. These 
requirements specifically address such electronic devices used in combination with flat-plate photovoltaic (PV) 
modules. 

NOTE It is acknowledged that the physical design of products covered by this scope may vary widely, it is 
anticipated that the requirements of this document may need to evolve to meet the unique safety requirements 
of such products, particularly if the photovoltaic element of the product is not of a flat-plate configuration. As an 
example, this document does not fully address the safety requirements of building-integrated photovoltaics 
(BIPV) and building-attached photovoltaics (BAPV) products, although they would fall under the scope of this 
document. 

The purpose of the requirements of this part of CSA-C22.2 No.62109 is to provide additional safety-related 
testing requirements for the following types of integrated electronics, collectively referred to as module 
integrated equipment (MIE): 
a) Type A MIE where the PV element can be evaluated as a PV module according to CAN/CSA-C22.2 No. 
61730-1 and CAN/CSA-C22.2 No. 61730-2 independently from the electronic element; 
b) Type B MIE where the PV element cannot be evaluated as a PV module according to CAN/CSA-C22.2 No. 
61730-1 and CAN/CSA-C22.2 No. 61730-2 independently from the electronic element. 

Items excluded from the scope: 

PV modules with only one or more bypass diodes as the combined or integrated element. Such products are 
covered by CAN/CSA-C22.2 No.  61730-1 and CAN/CSA-C22.2 No.  61730-2. 

Aspects included and excluded from scope: 

All aspects of CAN/CSA-C22.2 No. 62109-1:2016 apply. Addition to the list “excluded from the scope” is 
evaluating the MIE to CAN/CSA-IEC 61215-1.
