The solar panel converts sunlight into electricity and stores it in the Li-Fe battery via the MPPT controller, so that at night the battery can provide power to the solar powered street lamp. How long the solar street lamps can work during night? It depends on the power of battery charged during daytime and the output of the light during night. Our new integrated solar street lights can optimize the batteries via 4 ways.
Firstly, with the intelligent controller, no need people to control the on and off times for the light. We call this Light Control. The lamp automatically switch off when senses daylight, and turns on automatically to provide the required brightness when no daylight.
The second one is PIR Sensing Control. When no people, the light works with 30% power, and when the light senses people the lamp works with 100% power to optimize the batteries.
The third one is Timing control. You can set the power and time for the lamp. For example, from 7pm–12pm, the light works with 100% power, and the other hours works with 30% power.
The fourth one is APP Control. You can turn on, turn off or adjust the power on smart cellphones via APP very easily.
With the above 4 ways, the lamps can meet the requirements of lighting and at the same time save lots power to work longer time.
