China DC Combiner Box Manufacturers, Suppliers, Factory

The DC combiner box bus combines the DC inputs of four photovoltaic modules into a single output. Each channel is equipped with a fuse for added protection. On the output side, lightning protection and circuit breakers are provided. This configuration significantly simplifies the wiring process for DC distribution cabinets and inverters. The combiner box offers lightning protection, short circuit protection, and grounding protection.

Photovoltaic combiner boxes are categorized as intelligent boxes and non-intelligent boxes. Intelligent photovoltaic combiner boxes are equipped with monitoring units that can detect the input currents of each series, internal temperature, lightning protection status, circuit breaker status, and summarize output voltage, among other parameters.

The design and configuration of the combiner box strictly adhere to the "Technical Specification for Photovoltaic Node Equipment" CGC/GF 037:2014. Our aim is to provide users with safe, user-friendly, aesthetically pleasing, and practical photovoltaic system products.

The DC combiner box is designed for outdoor wall mounting and is suitable for harsh environments. While the core components remain fixed, other parts can be customized to meet specific user requirements.
