What is an inverter?

One of the most important components for the operation of a solar system is the inverter, which converts the electric current generated by the solar modules into alternating current.
Photons from the sun’s rays stimulate electrons in the photovoltaic cells that make up the modules. These then provide the same voltage. However, this electricity cannot be used in homes or on the grid, but must be converted into alternating current at a constant frequency of 50 Hz. This modification is carried out by a switching device that can produce an alternating current or voltage change at 230 V and 50 Hz. The inverter also optimizes the performance of the PV system to maximize solar energy production and protect the system from overvoltage.

There are many types of inverters on the market. It is important to select the right inverter, which must match the size of the solar system, both in terms of size and power output.

The type of connection between the solar modules and the inverter must support the highest voltage and current values that can be generated. This depends on how many strings make up the total PV system and how many modules are connected in series in each string.

The inverter can be single-phase or three-phase. Generally, single-phase systems are used for small systems and three-phase systems for medium and large systems. The hybrid inverter with storage system is a third option, in addition to these two, that can be used to control self-consumption in the home.
