DC to ACAn inverter is an electrical device for converting direct current into alternating current. In this way, solar power can be fed into the public grid, where it becomes available as conventional electricity for all electrical applications. The average level of efficiency is between 93 and 98 %.To achieve optimum efficiency, care has to be taken that the inverter is ideally designed for the necessary output. Depending on the type and design of the photovoltaic system, use is made either of insular, stand-alone inverters or grid feed inverters. These are, in turn, subdivided into different types:
 String inverter
String inverters are the most commonly used inverters in photovoltaics and are noted for their excellent value for money. They have higher voltages than module inverters and also have slightly higher losses.  Central inverter
Central inverters are large inverters that are usually accommodated in a room of their own. The efficiency of these units is particularly high, but they need plenty of room and are relatively expensive, which is why they are generally only used for large photovoltaic installations.
