Solar PV junction box applications and regulations

Types of junction boxes: photovoltaic power generation junction box is divided into crystalline silicon junction box, amorphous silicon junction box, building curtain wall junction box, explosion-proof junction box; junction box composition: box, cable and RF connector three-part composition; box composition: the box bottom (including copper amount of junction head or metal junction head), the cover, diode; cable is divided into: 1.5MM2, 2.5MM2, 4MM2 and 6MM2, etc., these points of the common The cable is divided into

Junction box selection important to look at the information should be the current specifications of the device, a critical current on the work, a short-circuit fault current, of course, short-circuit fault current when the components can export a relatively large current, according to the short-circuit fault current measurement of the rated current current of the junction box should be a relatively large security performance, according to the relatively large current on the work on the calculation of the junction box, then also a little smaller security performance.
