Solar energy is considered the most advantageous among the renewable power sources. The sun rays are captured by the solar PV modules that convert them to electrical energy which is then used for different purposes.

However, this electrical energy produced by the PV module is in the form of DC which is converted into AC power through an electricity inverter called a solar inverter.

There are different types of solar inverters; one of the most advanced types is Micro Inverter or Solar Micro Inverter. The micro inverter is the most reliable and efficient technology for the solar system. In this article, we will focus on this inverter's function, advantages, and disadvantages.

A solar micro inverter is a simple and smart electronic device that can be installed separately on a single solar PV module to convert its DC power to AC power. Then, several micro inverters are mutually connected to obtain the output. These inverters are substitutes for traditional string and main solar inverters and are also available with the feature of maximum power point tracking (MPPT) to get maximum power output from a solar panel.

The main type of micro inverter is the “Solar Grid-tie Micro Inverter” (Figure 1) which can synchronize the voltage, frequency, and phase of solar power to the grid and is able to feed the excessive power to the main grid at 120V/60Hz or 230V/50Hz efficiently. These inverters are available with different rated power of 300W to 2800W, transforming 24V/48V DC power produced from a solar panel to 120V/230V AC power.

Having a solar system with solar micro inverters creates more convenience for consumers. These inverters are successful in residential applications where maximum power is required from each module of small-size arrays. Additionally, solar grid-tie micro inverters are more useful to save and earn money through net metering. Whereas, the aforementioned advantages and disadvantages of solar micro inverter will be informative for users to make this product an ideal choice for them.
