Operation of a photovoltaic system is relatively simple. Photovoltaic cells in solar panels under the influence of solar energy use photovoltaic effect, which arises as a result of current. With the inverter is converted into alternating current for the electrical parameters corresponding to the public network.
There are two types of solar systems - network connected and autonomous.
Solar Inverter (inverter) - "heart and brain" is responsible for the photovoltaic system. Converts the direct current supplied by the solar panels into alternating current for the public network parameters. The biggest (nearly half of global output inverters) produced by German company SMA.
