Junction boxes for photovoltaic modules - Safety requirements and tests
|Publication Date:||1 May 2021|
|ICS Code (Solar energy engineering):||27.160|
This document describes safety requirements, constructional requirements and tests for junction boxes up to 1 500 V DC for use on photovoltaic modules in accordance with class II of IEC 61140:2016.
This document applies also to enclosures mounted on PV-modules containing electronic circuits for converting, controlling, monitoring or similar operations. Additional requirements concerning the relevant operations are applied under consideration of the environmental conditions of the PV-modules. This document does not apply to the electronic circuits of these devices, for which other IEC standards apply.
NOTE For junction boxes in accordance with classes 0 and III of IEC 61140:2016, in photovoltaic-systems
