A solar inverter or PV inverter, is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

Solar inverters use maximum power point tracking (MPPT) to get the maximum possible power from the PV array.

Solar inverter is classified in three different types:

1. Off grid – An off-grid solar inverter is a solar device that works without a utility grid. It converts DC current generated by solar panels into AC current to power your home.
2.  On Grid – An on-grid solar inverter will only work when there is a constant electricity supply from the power grid.
3. Hybrid – A hybrid solar inverter is the combination of a solar inverter and a battery inverter into a single piece of equipment that can intelligently manage power from your solar panels, solar batteries, and the utility grid at the same time.
