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.

: Voltage conversion capability
Grid connected cabinets can achieve voltage conversion between different voltages.

: Efficient and energy-saving
By using high permeability and low loss amorphous alloys or high-quality silicon steel sheets as the core material, and optimizing the winding design, the no-load and load losses are significantly reduced, and the energy conversion efficiency is improved.

: Intelligent temperature control and monitoring system
Equipped with intelligent temperature control and monitoring system, real-time monitoring of operating parameters such as temperature, current, voltage, etc., to ensure that the transformer is always in the optimal operating state.

: Multi scene fusion
Combined with electric vehicle charging stations, virtual power plants, etc., a distributed energy network is constructed to adapt to various application scenarios.
