The invention provides a three-phase microgrid inverter for a photovoltaic microgrid and relates to the technical field of photovoltaic microgrids. The three-phase microgrid inverter comprises an inverter body whose back part is provided with a mounting plate. The inverter body is connected to the mounting plate through a connection block. The top of the inverter body is provided with a heat radiation device, and at the same time, the bottom of the inverter body is also provided with a condensing device. The mounting plate comprises a plate body whose front side is provided with a groove. Thegroove is internally provided with a cavity whose internal part is movably equipped with a worm. Compared with a traditional photovoltaic microgrid three-phase grid-connected inverter, the inverter ofthe invention has the advantages that the installation is more simple and convenient, the installation and disassembly can be completed without using a tool such as a screwdriver, compared with the traditional photovoltaic microgrid three-phase grid-connected inverter, when the inverter is used, through setting an exhaust fan, the inverter communicates with outside air, and the heat in the inverter is taken away by the flow of the air.
Description
technical field [0001] The invention relates to the technical field of photovoltaic microgrids, in particular to a three-phase microgrid inverter for photovoltaic microgrids. Background technique [0002] Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads and monitoring and protection devices. The power sources in the microgrid are mostly distributed power sources with small capacity, that is, small units with power electronic interfaces, including micro gas turbines, fuel cells, photovoltaic cells, small wind turbines, and energy storage devices such as supercapacitors, flywheels, and batteries. They are connected to the user side and have the characteristics of low cost, low voltage and little pollution. [0003] In a general photovoltaic power station system, many parallel photovoltaic strings are connected to the DC input terminal of the same central...
