Photovoltaic system loss during work

There are more or less losses in the photovoltaic system during work. Among them, there are many links that cause the loss of power generation of photovoltaic power plants. loss due to matching. 2. Inverter loss: Inverter-related losses include the loss of the inverter itself, the loss caused by MPPT tracking in the conversion of DC to AC, and the loss of the inverter itself mainly includes: the efficiency of the inverter, overload loss, and power threshold Loss, overvoltage loss, voltage threshold loss. 3. Cable loss: Cable loss is mainly due to ohmic loss caused by voltage drop, which needs to be determined based on the actual use of cables in the project. Cable losses mainly include AC and OCX cable losses. AC cable loss: refers to the loss caused between the AC output and the transformer connection point. DC cable loss: refers to the loss caused by the photovoltaic array, the output end of the combiner box, and the DC input end of the inverter.
