Product Description

Application
Solar cable also called photovoltaic cable, they are series cables between photovoltaic modules and modules on the DC side of the photovoltaic power generation system, parallel cables between strings and between strings and DC distribution boxes (combiner boxes), and DC distribution boxes to inverters. It can also be used for AC application cables for the connection between the inverter and the transmission grid. Photovoltaic cables supporting other photovoltaic modules are exported to Europe, and the cables must comply with the TUV MARK certificate issued by TUV Rheinland, Germany.
