An electronic circuitry that converts direct current DC into Alternating current AC is called a power inverter or inverters. These are widely used in DC power source usage, Uninterruptible power supplies, Electric motor speed control, Refrigeration compressors, power grids, solar and many others.
A solar power inverter acts as a balance of system components of a PV system.

And these have specially adapted functions with photovoltaic arrays, which include maximum power point tracking and anti-islanding protection. While the solar micro-inverters are able to enhance the complete efficiency of the system and the total output can be connected to the electrical grid.
