12V—24V, is the system working voltage, DC.
Description of the working principle of solar street lights:
(1) During the daytime, under the control of the intelligent controller, the solar panel absorbs the solar light and converts it into electrical energy after being irradiated by sunlight. During the daytime, the solar battery module charges the battery pack, and the battery pack provides power to the LED light source at night. , to realize the lighting function.
(2) The DC controller can ensure that the battery pack is not damaged due to overcharge or overdischarge, and has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.
Solar street light product parameters:
(1) Main material: the light pole is all-steel structure, and the whole is hot-dip galvanized/sprayed;
(2) Solar cell module: crystalline silicon 15-80WP (configured by load);
(3) Controller: dedicated controller for solar lamps, light control + time control, intelligent control;
(4) Energy storage battery: fully enclosed maintenance-free lead-acid battery 12V17Ah—80Ah;
(5) Type of light source: energy-saving and high-power integrated LED, rare earth high-efficiency energy-saving lamp;
(6) Protection class: IP65;
(7) Operating temperature: -30 degrees to 70 degrees, wind resistance ≥ 150Km/h;
(8) Lighting time: 4 to 14 hours;
(9) Light pole height: 2 meters to 4 meters;
(10) It can work continuously in rainy weather.
Solar street lights do not need to lay underground cables, and do not need to pay for lighting electricity. The key components of solar garden lights, solar panels, solar DC street lights intelligent controllers, maintenance-free batteries, and lighting fixtures have all passed the National Development and Reform Commission/GEF/World Bank Photovoltaic Product Certification .
