PV Grid-Connected Cabinet(Also known as Photovoltaic Grid-Tie Distribution Box or PV Combiner Grid Cabinet)

The PV grid-connected cabinet is a key power distribution unit that connects the solar photovoltaic array to the power grid. Its primary function is to safely and compliantly feed the AC power—converted from the DC output of the PV system via inverters—into the utility grid or the user-side grid. In addition to grid connection, it also provides protection, monitoring, and metering functions.

Installation Types:
Indoor Type:
Installed indoors (e.g., in electrical distribution rooms), typically with a protection rating of IP30 or IP40, suitable for stable indoor environments.

Outdoor Type:
Designed for outdoor environments, with features such as waterproofing, UV resistance, and wide temperature tolerance. Protection rating is IP54 or higher, commonly used in rooftop PV systems and ground-mounted solar power plants.

Importance:
The PV grid-connected cabinet serves as the “safety gateway” between the photovoltaic system and the grid. Its performance directly affects the safety, stability, and efficiency of the grid connection and overall power generation. Proper selection and installation must strictly comply with grid codes and industry standards.
