Abstract：A method of combining grid and off-grid photovoltaic power generation system with LED lighting is proposed.The photovoltaic power generation system,State Grid system,battery pack and other equipment are combined according to certain configuration requirements to form a photovoltaic grid and off grid power generation system,which is directly used for the power supply of LED lighting fixtures.The system outputs 220 V AC power,which reduces line losses during transmission compared to traditional low-voltage DC power supply,adopting a wide voltage driving power supply to reduce the instability of LED lighting system.
