PV Grid-Connected Cabinet
Core grid-connected distribution equipment for PV power generation systems, enabling power filtering, metering, protection, and remote monitoring to ensure safe and compliant grid connection. Widely used in various PV and energy storage supporting systems.
Product Description
The PV grid-connected cabinet (also known as PV grid-connected distribution cabinet / grid-connected switchgear) is the core power distribution equipment in photovoltaic power generation systems for transmitting AC power to the grid. It connects the AC combiner box (or inverter) to the grid (or transformer). Typically, it features a cold-rolled steel sheet enclosure with plastic spraying and an IP rating of IP30 or higher, and incorporates key components such as circuit breakers, disconnectors, earthing switches, voltage/current transformers, surge protective devices (SPDs), metering instruments, and measurement, control, and protection devices. It enables filtering, metering, overload/short-circuit/ground fault protection, lightning protection, grid-connection switching, and fault isolation for the AC output of the PV system. Some units integrate intelligent measurement and control modules that collect real-time data on grid voltage, current, power factor, and power quality, supporting remote monitoring and dispatch via RS485 interface (Modbus RTU protocol). It is compatible with voltage levels such as AC380V/400V (low-voltage grid connection) or 10kV/35kV (medium-voltage grid connection), and meets operating environment requirements of -30°C to +70°C. It effectively ensures safe, stable, and compliant grid connection of PV power, and is widely used in distributed PV projects, large-scale PV power stations, and energy storage supporting systems.
