How do you know whether to choose a central inverter and a microinverter? Know the differences!

29 de August de 2020


We currently have a large number of elements that help us make natural resources more efficient and make the most of them. On the energy issue we have the central inverters and the microinverters. But, do you know what the differences are between inverter and microinverter?

Advantages of central inverters

They have high efficiency and a long history in the market, making them a reliable technology. Its cost is less than that of a microinverter. In addition, its maintenance is easier because it is a single unit.

Disadvantages of central inverters

The installation of central inverters can be more complicated than that of microinverters. With central inverters it is not possible to monitor the energy produced by each panel individually, but the entire system as a whole can be monitored.

Because they work with a higher voltage, they require more precise precautionary measures.

They make little noise, however due to their size they require a special space for their installation. Usually, the warranty for central inverters is 5 years as opposed to 20 years offered by microinverters.

Usually, the warranty for central inverters is 5 years as opposed to 20 years offered by microinverters. On the other hand, microinverters are small inverters connected to the grid. Microinverters, compared to central inverters, are smaller in size and weight. Microinverters are small components that are installed on the rails of the anchor system, below each photovoltaic solar panel.

Advantages of microinverters

As an advantage over central inverters, microinverters simplify the design of photovoltaic systems and are quiet. The installation of this system is easier. In shady places, they are more convenient as the energy production of the system is not compromised. Due to their voltage, they last longer than central inverters and in case of shading the panels are not so easily damaged by points with high temperatures. Furthermore, the energy produced by each panel can be monitored individually. If a microinverter fails, only the power output of a single solar panel is affected and not the entire system, unlike central systems. The warranty offered by microinverters is up to 20 years, compared to 5 years offered by central inverters.

Disadvantages of Microinverters

Among the disadvantages of microinverters we find their cost compared to central inverters. Compared to central inverters, there is not much variety in the market, understanding the assumption that the lower the demand, the higher the supply or price.

On the other hand, because they are installed under the solar panel, they can present problems at very high temperatures. Now you know the differences between inverter and microinverter to choose the best element for your home.
