Solar Array Junction Box For 30kwp

We are successfully established manufacturer, exporter and supplier of Solar Array Junction Box For 30KWp in Chennai, Tamil Nadu, India. Solar Combiner Box is a device that combines the output of multiple strings of PV modules for connection to the inverter. It is typically used in the larger commercial and utility scale PV power plants (greater than 500kW). There are several key elements to pay close attention to when specifying or evaluating a string combiner box. The first element is the enclosure. Most string combiners are available in outdoor-rated enclosures, typically NEMA 3R, 4 or 4X, with NEMA 3R being the minimum requirement. More typical today is a NEMA 4 steel or NEMA 4X non-metallic enclosure. In high humidity areas, or areas with a large swing in humidity, you might consider adding a condensation or breather vent that will allow pressure equalization to the enclosure, but prevent water molecules from entering it.
The enclosure is often one of the more expensive components in the string combiner but ita s important because it has a direct impact on the life of the combiner. The enclosurea s mounting position, size and color directly affects the internal temperatures. Lighter colors typically absorb less solar radiation than darker colors.
