UNE-EN IEC 62109-3:2023

1 Scope and objecThis clause of Part 1 and Part 2 is applicable with the following exceptions:1.1 ScopeThis Part 3 of IEC 62109 covers the particular safety requirements for electronic elements that are mechanically and/or electrically incorporated with photovoltaic (PV) modules or systems.NOTE Electrically incorporated means that the whole combination of electronic device with the photovoltaic element is sold as one product. Nevertheless, tests provided in this standard 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.1.1.1 Equipment included in scopeAddition: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, protection, control, monitoring, or communication.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 IEC 61730-1 and -2.NOTE 1: These requirements specifically address products used in conjunction with flat-plate photovoltaic (PV) modules. However, the scope of this standard covers products that use solar cells of any design as a source of energy supply. As it is acknowledged that the physical design of products covered by this scope may vary widely, it is anticipated that the requirements of this standard must necessarily 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 standard does not fully address the safety requirements of BIPV and BAPV products, although they would fall under the scope of this standard.NOTE 2 According to this standard actively controlled semiconductor switches used for active bypass diodes are not considered as a bypass diode covered by IEC 61730-1.Additional Subclause:1.1.1.300 Designs included in scopeThe purpose of the requirements of this part of IEC 62109 is to provide additional safety-related testing requirements for the following types of integrated electronics, collectively referred to as module integrated electronics (MIE):a) Type A where the PV element can be evaluated as a PV module to IEC 61730-1 and -2 independently from the electronic element;b) Type B where the PV element cannot be evaluated as a PV module to IEC 61730-1 and -2 independently from the electronic element;1.2 Object1.2.2 Aspects excluded from scopeAddition to the list:" Evaluating the PV module to the IEC 61215-1 when the PV module is used with MIE.
