The Importance of Choosing the Right Solar Connector - Sunkean.com
In photovoltaic systems, the junction boxes and connectors of photovoltaic modules are small parts that are not noticeable. However, if the quality of these two widgets is not good enough, it will be a huge security risk! A joint investigation by Fraunhofer ISE and TUV found a high probability of fires caused by connectors. The fundamental reason for the fire of the connector is that the resistance of the connector increases under the condition of current flow, which increases the temperature rise and exceeds the temperature range that the plastic shell and metal parts can withstand, thereby causing a fire. Therefore, the failure of the connector and the cause of the fire are the result of the combined action of the plastic shell and the metal parts. Failure analysis caused by metal parts The metal part is the main body of the connector and the main flow path. When operating in various environments, stable resistance is the precondition to ensure the normal operation of the conne...
