In the prior art, the grid integrated solar inverter has high working efficiency, and the operation in the lower power range and the higher power range reduces the efficiency of these devices to some extent due to the technical influence of the inverter. The rated power of a huawei solar inverter is typically specified by the inverter manufacturer taking into account standard test conditions /or normal operating conditions.
If the inverter size is too large, higher losses will occur because the inverter converts more energy in the lower power range. If the inverter size is too small, the inverter is in the higher power range. Higher energy losses occur when converting more energy. In particular, due to the maximum power limitations of the inverter, solar inverters may reject a fraction of the very high incidence of disposable solar energy.
Therefore, the correct size determines the optimal solar generator size associated with the size of the inverter, which maximizes its annual energy conversion. Due to the characteristics of the inverter efficiency curve, the optimal size of the inverter depends on: the technical aspects of the solar inverter and the photovoltaic module, the climatic aspects of the location where the inverter is installed and the simulation of the time resolution that must be completed in order to obtain Annual energy conversion.
Inverters play a vital role in any solar system and are often considered important equipment for photovoltaic operation. The basic function of the inverter is to "reverse" the direct current (DC) output to alternating current (AC). Inverter technology has made significant progress, so in addition to converting DC to AC, they offer many other features and services to ensure that the inverter can operate at optimal performance levels, such as data monitoring, advanced utilities. Control, application and system design engineering.
