Circuit Diagram

Tips: Solar Street Light Controller Replacement Common Sense

Whether the light source has a built-in drive. If the light source itself has a drive, the controller uses a normal solar street light controller. If there is no driving power in the light source, then you must purchase a constant current control integrated machine.
The arrangement of the light source bead. If it is more than 3 strings, use the step-down street lamp controller, 4 or more strings, and use the step-up solar street lamp controller, up to 14 strings.
Solar power. If the power of the solar controller is less than 150W, use a 10A controller and use a 20A controller between 150W and 250W.
Type of battery. Know whether it is a lead acid or gel battery, or a lithium battery. The type of battery is different, and the controller selection is different because the battery charging parameters are different.
The power of the light source. If it is 30W or less, use 10A current controller. If it is 30W~60W with 20A controller, here is the 12V system voltage, and the power is multiplied by 2 when 24V voltage.
