Detailed Product Description

Waterproof IP66 Outdoor Solar PV Combiner Box / Junction Box For Solar Power Plants


Special design /Non standard/OEM PV Project SCB


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.


Solar Combiner Box (Steel/PC)

Key features: 

1.According to the function, it will have a standard combiner box (SAB) and an intelligent combiner box (SCB).

According to different working environment, it will have polycarbonate (PC) and steel made boxes .

2.We choose all materials strictly on quality first principle. All components comply with DIN and VDE standards, and all adhere to the highest quality standards. 
3.CE, TUV, CQC certified. 

4,Meet outdoor installation requirements, IP66 . With anti-UV, anti-acid, anti-alkali, moisture, mildew, rodents and so on functions.

5,All components meet rated voltage DC1000 V requirements. 

6.With fuses on Inputs, switches on outputs, and SPD in both poles.

7,Can monitor the current of each string, voltage, status of circuit breaker and SPD. Can display and read the data on both local and background part. Can accurately identify the fault and its position(only applicable to SCB-II)
