One critical task of the inverter is to make sure that the PV modules are always working at their optimum power levels: Depending on temperature and irradiation intensity, there is always a precise combination of electrical current and voltage that allows a PV module to achieve its maximum power, which is also called its maximum power point or MPP.
There are four main types of solar power inverters: Also known as a central inverter. Smaller solar arrays may use a standard string inverter. When they do, a string of solar panels forms a circuit where DC energy flows from each panel into a wiring harness that connects them all to a single inverter.
In order to couple a solar inverter with a PV plant, it’s important to check that a few parameters match among them. Once the photovoltaic string is designed, it’s possible to calculate the maximum open-circuit voltage (Voc,MAX) on the DC side (according to the IEC standard).
A solar inverter is really a converter, though the rules of physics say otherwise. A solar power inverter converts or inverts the direct current (DC) energy produced by a solar panel into Alternate Current (AC.) Most homes use AC rather than DC energy. DC energy is not safe to use in homes.
The input section of the inverter is represented by the DC side where the strings from the PV plant connect. The number of input channels depends on the inverter model and its power, but even if this choice is important in the plant design, it does not affect the inverter operation.
