Photovoltaic inverter for grid connection: it's a special type of inverter designed specifically to convert electrical energy in the form of direct current produced by the photovoltaic modules into alternating current to be entered directly into the power grid. These machines extend the basic function of a generic inverter with a highly sophisticated and advanced functions through the use of special software control systems and hardware that allow you to extract the maximum power from the solar panels available in all weather conditions. This function is called MPPT, an English origin which stands for Maximum Power Point Tracker. The photovoltaic modules in fact, have a characteristic curve V / I such that there is an optimum working point, said precisely Maximum Power Point, where it is possible to extract the maximum power available. This point varies continuously as a function of the level of solar radiation that strikes the surface of the cells. It is evident that an inverter able to remain "hooked" at this point, will always get the maximum power available in any condition. There are various techniques of realization of the MPPT function, which differ for dynamic performance (settling time) and accuracy. Although the accuracy of MPPT is extremely important, the settling time is, in certain cases, even more. While all inverter manufacturers are able to obtain great precision sull'MPPT (typically between 99 to 99.6% of the maximum available), only a few are able to combine precision speed. It is in fact on days with variable cloudiness occurring solar power surges large and sudden. It is very common to be variations from 100W / m² to 1000-1200W / m in less than 2 seconds. In these conditions, which are very frequent, an inverter with settling times lower than 5 seconds can produce up to 5% -10% of energy in more than a slower one.
