grid-connected cabinet

The photovoltaic grid-connected cabinet is an important part of undertaking centralized inverters and step-up transformers or AC combiner boxes and step-up transformers. The incoming line of this photovoltaic grid-connected cabinet adopts circuit breaker input or direct input, and the output adopts circuit breaker or load Isolation switch, the busbar is connected by electroplating or purified busbar, and provides secondary lightning protection. The rated voltage of the system is up to AC690V, and the protection level is IP40 indoors and IP65 outdoors; the secondary measurement and control cables, the current is greater than The cable of 2.5mm², the cable with the voltage of 1.5mm², the control cable of greater than 1.0mm², the measuring current transformer is the current transformer of class 0.5, and the measuring transformer is the current transformer of class 0.2S. It can also add related functions according to customer requirements. This product adopts professional electrical design and component selection, which makes the internal structure of the cabinet safe, concise, beautiful, convenient for on-site wiring and maintenance, and ensures the stable operation of the equipment for a long time.
