1 Scope

This standard specifies the terms and definitions, structure and performance requirements of connectors for terrestrial photovoltaic systems (hereinafter referred to as connectors).

Law, inspection rules, identification, packaging, transportation, storage and so on.

This standard applies to the use of GB/T 20047.1 defined in the application of the A level of photovoltaic systems with non-breaking capacity of the DC connector, and the amount

Constant voltage is not greater than 1500V DC, rated current is not greater than 125A. According to GB/T 20047.1 defined the application of class B and C of the photovoltaic

The component connector can be referenced.

Note. In the case of a load, the connector is not allowed to engage or disengage.
