3.Product feature and application of solar street light charge controller

-The design of IP22 level and ABS shell helps effectively prevent fire and good cooling. 

-12 V/24 V system voltage.

-LED numeric display.

-An upgraded 3-stage PWM charging algorithm applies an equalizing charge to the battery every week, effectively preventing the battery from non-equalization and sulfuration and therefore extending the battery's service life.

-Up to 18 kinds of load working modes facilitate the product's application to different types of road lamps and monitoring devices.

-Charging program options are available for sealed, GEL and flooded lead-acid batteries and ternary-material lithium and lithium iron phosphate batteries. 

-An external temperature sensor helps deliver high-precision temperature compensation. 
-Parameter settings of power-down saving functions eliminate the trouble of repeated settings, making operation easy and convenient. 

-Various kinds of state indicators. 

-Overcharge, over-discharge and overload protection, as well as short-circuit and reverse-connection protection.
