Junction boxes play a major role in the functionality of a PV module. They ensure that the current from a solar module can flow in the right direction. Defects at the junction box can lead to heat accumulation with harmful consequences for the module.
IEC 62790:2020 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 .
The junction box installation is one of the key steps in the assembly process of PV modules, using semi-automatic production methods to complete the four ste.
surface preparation, and the substrate. Historically, the system of adhesion for junction boxes (j-boxes) has proven an essential product development task for photovoltaic (PV) module manufacturers. The possible consequences of failure in the field for the j-box include electrical arcing and subsequent initiation of fire. The of detachmentthe j-
