Product Overview

The BWG photovoltaic grid connected cabinet is an important component that undertakes 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 electroplated or purified busbar, and provides secondary lightning protection. The maximum rated voltage of the system is AC690V, and the protection level is IP40 indoors and IP65 outdoors. For cables with current greater than 2.5mm ², cables with voltage greater than 1.5mm ², and cables with control greater than 1.0mm ², the measuring current transformer is a 0.5 level current transformer, and the measuring current transformer is a 0.2S level current transformer. Relevant functions can also be added according to customer requirements. This product adopts professional electrical design and component selection, making the internal structure of the cabinet safe, simple, beautiful, convenient for on-site wiring and maintenance, and ensuring long-term stable operation of the equipment.
