D. Miro Tool

In large photovoltaic plant where there are modular inverters, for example composed by two or moremodules in parallel, the conversion efficiency can be optimized using only the minimum number ofmodules needed to deliver the power coming from the strings. The "Miro" toggles the modules and theirline contactor to the output to be delivered and requires no additional body (contactor DC).

Miro

Under conditions of low irradiance, theefficiency of each inverter decreases sharply tovalues of less than about 25% of its ratedpower. The voltage output characteristic ofphotovoltaic cells, also exhibits a maximumwhich becomes less pronounced withdecreasing irradiation and reading of thecurrent string is gradually less accurate. Thesefactors reduce the efficiency of MPPTalgorithm. It follows that from the standpoint ofefficiency, the division into sections is mostadvantageous when the radiation decreasesand becomes instead more convenient

configuration with a single inverter.
