What Is the Size of the Application of Solar Energy Inverters?

Introduction to solar energy inverters

A solar power inverter, also known as a power conditioner or power regulator, is an essential component of a photovoltaic system. Physically, the process of converting DC electricity into AC electricity is called inversion, and the device that performs this process is called an inverter. The name 'solar inverter' comes from this. The main function of a solar electric inverter is to convert the DC electricity generated by the solar panels into AC electricity for household use. Inverter is the heart of the photovoltaic system, and all the electricity generated by the solar panels must go through the inverter's processing to be outputted externally, making the inverter play an important role in the operation of the entire system.

Solar energy inverters: Maximum power tracking function to ensure maximum output power

The current and voltage of solar panels vary with the intensity of solar radiation and the temperature of the solar panel components. Therefore, the output power also varies. In order to ensure maximum output power, we need to obtain the maximum output power of the solar panel as much as possible.

When installing a photovoltaic system, many people have the idea of "even if the power grid is off, they can still use electricity at home." However, when the power grid is off, the photovoltaic system at home will also stop running. The reason for this is that nowadays, most inverters are equipped with an anti-islanding device, so solar energy inverters will stop working when the power grid voltage is 0. The anti-islanding device is a necessary device for all photovoltaic inverters connected to the grid, mainly for the safety of the power grid.

If you really want to use electricity at home when the power grid is off, you can consider installing a photovoltaic off-grid system. In this way, the electricity generated by the solar panels can be stored for use when needed.

Solar energy inverters: Automatically start and stop according to the output power of solar panels

After sunrise in the morning, the intensity of solar radiation gradually increases, and the output of solar panels also increases. When the output power of the solar panels reaches the required output power of the inverter, the inverter will automatically start to work. Once the solar inverter starts running, it continuously monitors the output of the solar panel components. As long as the output power of the solar panel components is greater than the output power required for the inverter to work, the inverter will keep running. Even in rainy weather, the inverter can continue to run. When the output of the solar panel components decreases, and the output of the inverter approaches 0, the inverter enters standby mode.
