EPC Solar Panel PV Combiner Box Multiple strings , Photovoltaic Combiner Box


Special design /Non standard/OEM PV Project SCB

Solar  junction box  for solar power plants&EPC of PV power station


Quick Detail:


In a large solar photovoltaic (PV) array, multiple solar modules are connected in series in a string to build the voltage up to proper levels for the inverter. Multiple strings of solar modules are then combined together in parallel to multiply the string output currents to higher levels for input into the inverter.





The 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 50kW). The combiner box commonly houses the input overcurrent protection fuse assemblies for several strings (from as few as 2 strings to as many as 32), as well as the combined bus of those inputs into a single main output.

Normally PV combiner box may also house several other components for the site, such as a DC disconnect, surge protective devices and string monitoring hardware.
