Microinverters in solar panels
Fri May 2022

In the world of solar energy there is a component called a microinverter, which helps to maximize the performance of the individual solar panel. Continue reading to know a little more about him.

What is a microinverter?

A microinverter is a tiny inverter that converts the direct current DC from solar cells into alternating current AC, which is suitable for home use. Due to this, it is not necessary to acquire a conventional inverter, since the electricity produced by the solar panels is incorporated directly into the home’s electrical network.

Microinverters solar panels have more advanced technology than traditional inverters and have great advantages in terms of their use in solar equipment.

The microinverter connects to a single solar panel, although there are also dual microinverter models, which can be connected to two modules at the same time.

This component is responsible for transforming the DC power generated by the solar panels into AC power, the form of energy used by end consumers.

Thanks to the exponential growth of self-consumption worldwide, many users have decided to incorporate solar energy solutions into their homes that allow them to obtain medium-term profitability in electricity consumption, being partly self-sufficient. For this reason, it is clear that self-consumption and the conception of the use of clean, efficient and respectful energies with the environment have been installed in our lives.

How does a microinverter work?

Thiscomponent was designed mainly for solar energy self-consumption installations and makes each solar panel work at its maximum possible power. This is because if one panel is shaded, but the rest are not, it will affect the solar energy production of the rest.

This phenomenon is known as “mismatch”, which causes the current that runs through a series of solar panels to be determined by the current obtained from the panel that operates with the lowest performance and which will lead to a little effective performance of the installation.

Benefits of microinverters

From a  technological point of view and thanks to its advantages for residential and business users, this component is a versatile and widely accepted option. Below is a list of the main benefits that it offers:

  • They work independently.
  • They transform direct energy into alternating.
  • Increases the output of each solar cell individually.
  • They are safer and more reliable than ON GRID technology.
  • There are no high voltages thanks to the energy conversion.
  • Installation times are relatively quick.
  • They are easily connected through plug and play connectors.
  • It will provide you with greater savings due to its quick installation.

How do I know if I need a microinverter?

For the installation and operation of these components to be efficient and to have good performance, they are designed for use in very specific photovoltaic installations. 

In other words, microinverters are developed for small domestic installations whose total power is less than 1000W or systems where some component may present shading problems. Additionally, they are designed for locations with different inclinations for the panels or different orientation and allow them to be placed against the panels, thus saving an excessively large device in some position.

What drawbacks do microinverters have compared to traditional investors?

Starting with the most important, this component being a relative novelty compared to traditional inverters, the supply of solar microinverters on the market is even smaller.

Regarding maintenance , it is more expensive than that of network inverters, since they require the revision of more devices in terms of parts and equipment. Also, in installations that exceed 1500 W, the cost can increase considerably, making it not the best option. So you must evaluate whether or not it is convenient for you to use this component.
