What is a solar inverter?

O solar inverter (or photovoltaic inverter) is an electronic device that is indispensable in any photovoltaic solar energy system. Its main function is to convert to direct current (DC) produced by the modules or solar panels in alternating current (AC) which is the type of energy used by most electrical equipment and the conventional power grid.

Why are solar inverters important?

By continuously monitoring the performance of the system, inverters can detect and mitigate issues such as panel shading or malfunctions, thereby maximizing overall system efficiency. The efficiency and reliability of inverters are essential for the optimal performance of solar energy systems.

How to choose a solar inverter?

Check the rated power of the inverter against the total power of the solar panels installed. In on-grid systems, the inverter is usually sized a little below or close to the power of the modules (for example, a system with 5 kW of boards can use a 5 kW or 4.6 kW inverter, as small losses can occur).

How does a solar inverter work?

So the solar inverter works receiving direct current from the panels, optimizing this generation and converting to alternating current quality, safe and in sync with the network (where applicable).

What are the different types of solar inverters?

There are several types of inverters that might be installed as part of a solar system. In a large-scale utility plant or mid-scale community solar project, every solar panel might be attached to a single central inverter. String inverters connect a set of panels—a string—to one inverter.

Do inverters provide or absorb reactive power?

Modern inverters can both provide and absorb reactive power to help grids balance this important resource. In addition, because reactive power is difficult to transport long distances, distributed energy resources like rooftop solar are especially useful sources of reactive power.
