Solar inverter
A solar inverter, or PV inverter, converts the variable direct current output of a photovoltaic (PV) solar panel into a utility frequencyalternating current that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
