    Abstract：The model selection requirements for inverters in BIPV projects are elaborated by comparing the theoretical simulation date and the actual data of existing power stations. The specifications of relevant products of major inverter manufacturers at present are summarized, and the considerations for selecting the inverter in BIPV projects are proposed. In addition, quantitative analysis on the proportion of DC input power to the rated power of inverter is carried out while measured data are given based on practical cases.
