1. A solar inverter, or converter or PV inverter, 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. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
2. An inverter is an electronic device that can transform a direct current (DC) into alternating current (AC) at a given voltage and frequency. The inverters are used in photovoltaic off-grid (stand alone) for powering electric remote houses, mountain chalets, monile homes, boats an are also used in grid-connected photovoltaic systems to enter the current produced by the plant directly into the power grid distribution.
3. Inverter are the brains of the system. The main task of the inverter is to convert the DC power generated by the solar system into usable alternating current power.
Inverter enable the monitoring and the provision of diagnostic information.
