Photovoltaic module wet leakage current testing system

~1、 Application of Wet Leakage Current Testing System for Photovoltaic Modules

The wet leakage current test system for photovoltaic modules tests the insulation performance of the modules under humid working conditions, detecting whether moisture from rain, fog, dew, or snow has entered the working parts of the internal circuits of the modules, causing corrosion, leakage, and non safety accidents. The photovoltaic module wet leakage current testing system is a specially designed wet leakage current testing device for the solar photovoltaic module industry.
