Features of solar inverters
A solar inverter is a device that converts DC power in a solar battery into AC power. Inverter, also known as power regulator and power regulator, is an essential part of photovoltaic power generation system.
The working circuit of the solar inverter must be a full-bridge circuit. Through a series of filtering and modulation in the full-bridge circuit, the load and electrical properties of the current are changed to achieve the purpose expected by the user. A common solar power generation system mainly consists of four parts, namely solar panels, charge controller, solar inverter and battery.
The solar panel is a device that provides direct current and can convert solar energy into electrical energy; the charge controller is mainly responsible for controlling the conversion of energy; the solar inverter converts the direct current from the panel into alternating current for storage of the battery. The battery is mainly responsible for converting the energy. Alternating current is stored for human use. Solar inverters play a connecting role in the entire solar power generation system.
As one of the core equipment of solar photovoltaic power generation system, solar inverter has the following main characteristics:
The main features of solar inverters are centralized inversion and string inversion. The scale of solar power generation systems is generally very large. If one solar panel is used to correspond to one inverter, it will cause a waste of resources and is very unrealistic.
Therefore, in actual production, solar inverters centrally invert the DC power generated by all panels and convert it into AC power.
Therefore, the size of the solar inverter generally needs to adapt to the size of the panel. Therefore, a single solar inverter is obviously unable to meet this requirement. This leads to another characteristic of solar inverters, which are often used in strings. .
- High efficiency: The solar inverter adopts advanced frequency conversion technology, which can convert the DC power generated by the solar panels into AC power, and ensures that the overall conversion efficiency is as high as over 90%, which can maximize the efficiency of electric energy utilization.
- Strong stability: The solar inverter can realize the stable operation of the photovoltaic power generation system, and has comprehensive protection functions such as voltage, current, and temperature. It can effectively protect the photovoltaic power generation system from external interference and ensure the stable operation of the photovoltaic power generation system. Sex and bumpy sex.
- Intelligent: The solar inverter adopts digital control technology, which can monitor and analyze data in real time, thereby achieving precise control and prediction. It is in line with the trend of intelligent development and is of great help in improving the management and operation efficiency of photovoltaic power stations. .
- Low noise and low voltage drop: The high-quality electronic components integrated in the solar inverter can effectively reduce current and voltage fluctuations, reduce noise pollution, avoid energy consumption, and ensure the high-efficiency operation of the photovoltaic power generation system.
In general, the solar inverter is one of the most critical equipment in the solar photovoltaic power generation system. Its characteristics such as high efficiency, strong stability, intelligence, low noise, and low voltage drop provide very good conditions for the operation of the photovoltaic power generation system. Important safeguard.
