PV Combiner Iron Box

The company’s confluence box is divided into four categories: anti-reverse intelligent confluence box, anti-reverse non-intelligent convergence box, non-anti-reverse intelligent confluence box without anti-reverse non-intelligent convergence box. According to the number of input channels, it is divided into 6 channels, 8 channels, 10 channels, 12 channels, 14 channels, 16 channels and 18 channels. The anti-reverse intelligent convergence box is mainly composed of DC circuit breakers,It is composed of lightning protection, anti-reverse diode, cable interface, fuse, sampling board, monitoring board and auxiliary power supply board. 

The function of anti-reverse diode is to prevent the back filling of current between solar panels caused by local shadows or damaged battery panels, so as to avoid damage to other battery panels. The sampling board mainly samples the current of each branch line in the confluence box. PV busbar voltage sampling and monitoring board can monitor the state of lightning arrestors, circuit breakers, etc., communicate with the upper computer, and send the collected data to the upper computer in real time to monitor the current, voltage and various state quantities, etc.The convergence box without anti-reverse function does not have anti-reverse diodes. The non-intelligent convergence box does not have the functions of voltage, current, lightning protection status detection, DC circuit breaker status detection, etc.
