Product Introduction

Grid connected cabinet is an electrical device used to connect distributed energy sources (such as photovoltaic power generation systems, small wind power generation systems, energy storage systems, etc.) with the public power grid.

Application

: Photovoltaic power generation system
Grid connected cabinets are widely used in rooftop photovoltaic power stations, ground photovoltaic power stations, and other scenarios to connect photovoltaic energy to the grid.

: Small scale wind power generation system
Used to connect the output electrical energy of small wind turbines to the power grid.

: Energy storage
Grid connected cabinets can connect energy storage systems (such as lithium-ion battery energy storage) to the power grid, achieving charging and discharging control of the energy storage system.

: Microgrids
In microgrids, it is used to connect distributed energy sources with the microgrid main grid, achieving bidirectional transmission and control of energy.

: Rated voltage
According to the voltage level of the power grid, common rated voltages include 380V, 10kV, 35kV, etc.

: Rated current
According to the capacity of distributed energy systems, the rated current range is usually from tens of amps to hundreds of amps.

: Grid connection method
Support three-phase grid connection and single-phase grid connection.

: Protection level
Usually compliant with IP54 or higher protection level, ensuring the reliability of equipment in harsh environments.

: Communication interface
Supports multiple communication methods such as RS485, Ethernet, GPRS, etc.

: Work environment
The temperature range for adaptation is -25 ℃ to+55 ℃, and the humidity range is 10% to 95% (without condensation).
