Classification and components of 50kw solar power generation system

First of all, we need to understand what 50kw solar power generation depends on, which is light energy. Light energy is converted into electrical energy through solar panels and then converted into required voltage and electrical energy by the controller and inverter for battery storage and use, and then utilized when needed. This is a simple component of a 50kw solar system.

      As clean energy, solar energy is more and more favored by people because of its environmental protection and convenience. Many countries vigorously advocate the development and utilization of solar energy. The subdivision of solar power generation can be divided into photothermal power generation and photovoltaic power generation. In fact, the power generation principle of photothermal power generation is basically the same except that the source of heat energy is different from that of thermal power generation. Photothermal power generation is to use the heat of light to convert it into kinetic energy through water vapor to drive the generator to generate electricity.

The production and sales volume, development innovation speed, and prospects of solar thermal power generation are weaker than those of photovoltaic power generation. Photovoltaic power generation is superior to solar thermal power generation in terms of popularization and economic cost. Solar power generation in society basically refers to solar photovoltaic power generation. Photovoltaic power generation is generated by the conversion of photoelectric energy through solar panels, and the light irradiated on the active surface of the solar cell is directly converted into electrical energy. It can be used independently or for power generation. The photovoltaic power generation system is composed of three parts: solar panels, also called solar panels (components), controllers, and inverters. Now photovoltaic power generation equipment and system technology are basically stable and reliable because of their long life. , Easy installation and maintenance are supported by many people.

50kw solar energy systems can generally be divided into two types of power generation systems: solar power generation systems and solar power generation systems.

A 50kw solar power generation system generally consists of 80pcs of 630W solar panel+ mounting bracket+ cables+combiner box+solar controller+40pcs or 80pcs 250AH batteries +50kw inverter

The working process of a 50kw solar system

During the day, under light conditions, the solar cell modules generate corresponding potentials, and form a solar cell square array according to the series and parallel connection of the modules, so that the voltage of the square array reaches the requirement of the system input voltage. Then charge the battery according to the charge and discharge controller, and store the electric energy converted from light energy.

At night, the battery pack provides input power for the inverter, and through the function of the inverter, the direct current is converted into alternating current, which is transmitted to the power distribution cabinet, and the power is supplied by the conversion function of the power distribution cabinet. The charging and discharging of the battery pack are controlled by the controller, so as to realize the normal use of the battery. The solar power generation system should also have limited load protection and lightning protection devices to protect against the overload operation of the system equipment and avoid lightning strikes and maintain the safe use of the system equipment.
