PV12/1 DC combiner box bus synthesizes DC, input 12 PV modules to 1 output. Each channel is equipped with a fuse.
Lightning protection and circuit breakers are installed on the output side. This realizes not only lightning protection, short-circuits protection, and grounding protection, but also makes the input wiring of DC power distribution cabinets and inverters simpler.There are two types of photovoltaic combiner boxes: smart boxes and non-smart boxes.The intelligent photovoltaic combiner box is equipped with a monitoring unit. The monitoring unit is responsible for detecting the “input current”, “internal temperature”, “lightning protection status”, “circuit breaker status” and “summary output voltage” of each string.
