PV Grid Connected Cabinet
Product Overview
The PV grid connected cabinet is an intelligent power conversion device used to connect photovoltaic power stations with the public utility grid. It integrates dedicated grid-connection switches, anti-islanding protection units, power quality management modules, intelligent monitoring systems, and high-precision metering instruments.
The capacity is designed to match inverter output, and the main circuit breaker is configured with a 1.2× current redundancy margin. It supports multiple voltage levels including 220V, 380V, and 10kV depending on system power requirements. The PV grid connected cabinet strictly complies with GB/T 7251 standards and meets the grid "four-capability" integration requirements. Optional RS485 communication allows remote monitoring and dispatch control. Outdoor versions use IP65-rated enclosures made of 304 stainless steel, with CCC certification and official grid-connection compliance.
Core Product Features
