Photovoltaic Low-Voltage Grid-Connected Cabinet

>>Product Introduction

The BWG photovoltaic grid-connected cabinet is a critical component connecting centralized inverters to step-up transformers or AC combiner boxes to step-up transformers. This photovoltaic grid-connected cabinet features circuit breaker input or direct input for incoming lines, and circuit breaker or load disconnect switch for output. The busbars are connected using electroplated or passivated busbars and provide secondary lightning protection. The system's maximum rated voltage is AC 690V, with an indoor protection rating of IP40 and outdoor rating of IP65. Secondary measurement and control cables include: current cables larger than 2.5 mm², voltage cables larger than 1.5 mm², control cables larger than 1.0 mm², measurement current transformers of class 0.5, and metering current transformers of class 0.2S. Additional functions can be incorporated based on customer requirements. This product utilizes professional electrical design and component selection, ensuring a safe, concise, and aesthetically pleasing internal cabinet structure, facilitating on-site wiring and maintenance, and guaranteeing long-term stable operation of the equipment.

>>Features and Characteristics

· Can be designed for fixed installation or plug-in installation;
· Utilizes circuit breakers and components from our company or renowned domestic and international brands to form functional units, offering excellent technical performance, safety, and reliability; · Can be assembled into various standard unit modules for customers to select and combine as needed;
· Employs isolation between zones and between functional unit inputs and outputs, effectively enhancing safety protection;
