The main function of the PV inverter

PV inverters are an important part of solar panels. They convert the direct current generated by the solar panels into alternating current. This makes it easier to use the electricity generated by the panels and feed it into household appliances. This article will discuss in detail how inverters work and their main functions.

What is a photovoltaic inverter?

A photovoltaic inverter is a device used to convert direct current (DC) to alternating current (AC).

Solar cells will generate DC power in sunlight, and the DC power stored in the battery is also DC power, but the DC power supply system has significant limitations. For photovoltaic power generation to be widely used in our daily life, inverters that can convert direct current into alternating current are indispensable.

As an important part of photovoltaic power generation, the photovoltaic inverter not only has the function of DC-AC conversion but also has the function of maximizing the solar cell performance and the function of system fault protection. This is done by using energy from the sun to convert a set of solar panels into usable electricity.

Inverter efficiency

The inverter’s efficiency refers to the ratio of the output power to the input power under the specified working conditions, expressed as a percentage. In general, the nominal efficiency of the photovoltaic inverter refers to pure resistance load under 80% load. s efficiency. Since the overall cost of the photovoltaic system is high, the efficiency of the photovoltaic inverter should be maximized, the system cost should be reduced, and the cost-effectiveness of the photovoltaic system should be improved. Currently, the nominal efficiency of mainstream inverters is between 80% and 95%, and the efficiency of low-power inverters must be no less than 85%. Therefore, in the actual design process of the photovoltaic system, not only should high-efficiency inverters be selected, but at the same time, the system should be reasonably configured to make the photovoltaic system load work near the optimal efficiency point as much as possible.


The main function of the photovoltaic inverter is to convert the electrical energy in the solar energy into usable electrical energy for use in the electricity-consuming area. The use of photovoltaic inverters is crucial to harnessing the power of solar energy.
