Solar street light MPPT charging system solutions are widely used in the lighting of urban and rural roads, highways, water conservancy dikes, bridges, islands, parks, industrial areas, urban squares, residential quarters, parking lots, and other places.
The system is mainly composed of photovoltaic modules, MPPT solar street light controllers, batteries and LED lamps. Solar street light MPPT charging system solution is a solution to outdoor lighting problems using MPPT charging method. The MPPT tracking efficiency can reach 99.9%, which significantly improves the energy utilization efficiency of the photovoltaic system, which is about 15% to 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.
Using advanced digital power technology, the circuit energy conversion efficiency is as high as 96%. Using the matching remote control SR-CU-ALL, using external transmission technology, you can directly debug various parameters in the solar street light controller, which is convenient and quick.
