There are a wide variety of MPPT solar controllers, and the selection of suitable models for solar street lamps needs to be taken into consideration in several aspects.
1.The power and voltage of a solar component.
If the solar panels below 120W/18V, 10A controller is OK, if 120V/18V~240W/18V solar panels, then use 20A street lamp controller.
2.Whether the LED light source has a built-in drive power. If the light source itself does not drive the power supply, then the constant current control unit with constant current should be selected. If the light source itself is powered by the power, then the ordinary type of solar street lamp controller should be chosen.
3.The light source with drive to see the arrangement of the lamp. If the 3 series is in parallel, the step-down constant current control unit is used, if it is more than 5 series, the lifting type constant current control unit is used.
4.According to the use of the environment. If it is outdoor, and there is no special sealing box, it is necessary to use the full waterproof IP68 grade solar energy street lamp controller. If there is a special sealing box, also can choose the plastic shell IP32 grade solar street lamp controller.
