With the rapid deployment of distributed photovoltaic power in large-scale industrial and commercial scenarios, the selection strategy of electrical systems has become a key link in engineering design. Based on the rooftop photovoltaic project of Xiamen Times New Energy Technology Co., LTD., this paper analyzes the configuration and selection of electrical equipment, anti-backflow control and power quality assessment, and constructs a full-process selection system covering primary equipment, secondary protection and operation assessment. The research results show that the configuration of various electrical equipment in this project is reasonable, the control logic closed loop is complete, the operating parameters are stable, and it has representativeness and replicable value.
