How to choose an inverter? How to match photovoltaic inverters with components?

Assume it is a grid-connected inverter: Grid-connected photovoltaic inverters are mainly divided into three categories: high-frequency transformer type, low-frequency transformer type and transformerless type. The transformer type is mainly considered from the two aspects of safety and efficiency. The aspects that should be considered when selecting a grid-connected photovoltaic inverter are: (1) Capacity matching design: The grid-connected system design requires that the battery array matches the power capacity of the connected inverter.

What are the application scope and installation methods of distributed photovoltaic power generation systems?

The applicable occasions of distributed photovoltaic power generation systems can be divided into two categories. They can be promoted in various types of buildings and public facilities across the country to form distributed building photovoltaic power generation systems. Distributed power generation systems can be established using various local public facilities and buildings to meet part of the electricity needs of power users and provide production electricity for high-energy-consuming enterprises.

Does poor grid power quality have an impact on photovoltaic power generation systems?

Power quality is mainly composed of two indicators: voltage and frequency. A general deviation (e.g. 5%) in these two indicators will not affect the stability of the power system. When there was a power shortage in the 1970s, the frequency of the East China Power Grid was as low as 46 Hz/S, and there was a general low voltage at the same time, but it still survived. Therefore, power quality has little to do with system stability.

What is an off-grid solar power generation system?

According to the different networking methods, there are mainly two types of solar power generation systems: off-grid and grid-connected. Off-grid refers to a power generation system independent of the public power grid. It is not limited to the location and can be installed and used by any user in need. Therefore, it is very suitable for installation and use in areas without power grids. Grid-connected refers to a system connected to the public power grid, which can achieve complementary electricity use, and the excess electricity can also be transmitted to the public power grid.
