- Application range:
The solar street light MPPT charging system solution is widely used in the lighting of urban and rural roads, highways, water conservancy embankments, bridges, islands, industrial areas, city squares, residential areas and other places. The system is mainly composed of photovoltaic modules, MPPT solar street light controllers, batteries and LED lamps. The solar street light MPPT charging system solution is a solution to outdoor lighting problems using MPPT charging. The MPPT tracking efficiency can reach 99.9%, which significantly improves the energy utilization efficiency of the photovoltaic system. It is about 15%~20% higher than the traditional PWM charging efficiency, which solves the problem of energy waste caused by the low charging efficiency of the traditional controller.
