Dual USB Output Photovoltaic Power Controller 12Volt 24Volt Automatic Identification LCD Display Solar Controller Three-stage Charging Management PWM Controllers

Features:
​The build-in industrial main control chip can automatically adapt to the input voltage of 12 volt or 24 volt.
Large LCD display with charging and discharging current display, cumulative power generations and discharge power query, temperature display and light control delay time display, and etc..
The charge and discharge parameters are adjustable, with power-off memory and other functions.
The dual USB output, with a maximum current of 2.5A, supports charging mobilephones with the iOS system.
Equipped with PWM charging mode, fully complete 3-stage charge management, charges a while, stops a while, small current charges when nearly full.
Build-in short-circuit protections, open-circuit protections, reverse protections, over current protections, all are self-recovery type, no damage to the controller.
Anti-backflow circuit design with low heat production.
​Discharge recovery voltage function: after battery discharge protection, the battery voltage rises to the recovery voltage, automatically opening the output.
Discharge cut-off voltage: when the battery is discharged to the voltage, the load is turned off to protect the battery and prevents the battery from being damaged by over-discharge.
Three load working modes design, easy to satisfied with your daily demands:
【24H】 load normally open mode (except battery under voltage)
【1-15H】the load is turned off when under light control and 1-15hours timer (automatically turn on the light at night for 1-15 hours and then turn off)
【OH】pure light control mode (turn off in the day; turn on at night)
