PV grid connected cabinet records the power generation and consumption of the photovoltaic system

PV grid connected cabinet records the power generation and consumption of the photovoltaic system

Short Description:

The internal structure of the photovoltaic grid-connected cabinet mainly consists of the following parts: Indicator light and anti-islanding device: Positioned at the top, they are used to display the grid status and provide protection against islanding. Metering room: Contains electricity meters and other metering equipment to measure and record the power generation and consumption of the photovoltaic system. Equipment in the metering room: Including electroplating meters and multiple control meters, which are used for electric energy metering and control of the system. Circuit breaker and current transformer: Distributed in different positions within the cabinet, they are used for circuit protection and current monitoring. Four-stage knife switch: Used to disconnect the circuit, including the neutral line, when necessary. Inverters and power delivery equipment: Located at the bottom, they convert direct current to alternating current and send the power back to the grid. These components work in unison to ensure the safe and stable operation of the photovoltaic system and optimize the utilization and distribution of electrical energy.‌

Overview details

CSGGD, CSJXF for large-scale photovoltaic grid-connected power generation systems.In order toreduce the connection line and power loss between the inverter and the grid-connected cabinet, it isconvenient to maintain and improve reliability, Generally, an AC combiner box is added between theinverter and the grid-connected cabinet, and the current is configured according to the power oftheinverter. In order to meet this requirement, Im is specially designed to be combined with photovoltaicinverter products to form a complete photovoltaic power generation system solution. The use oftheconfluence AC box allows the user to customize the current and voltage according to the AC and gridrated input current.This product is mainly used in the grid-connected line ofdistributedphotovoltaic system 100Kw-1Mw.
