Factory supplier 12V/24V solar charge controller with USB output,pwm solar charge controller,30A/50A price solar controller

 Solar controller, have USB and LED bulbs output, can used directly without battery! 

1. 12V / 24V automatic identification, suitable for 12V or 24V systems, capable of automatic identification
2. Intelligent optimal control algorithm to achieve the intelligent control and low-power design
3. With overcharge, over discharge, output short circuit, reverse polarity protection and other protection
4. With PWM Charging, charging voltage is less than 0.2V, using a three-stage charging: strong charge - balance charge - float
5. Suitable for GEL battery (maintenance-free batteries) or maintenance-free lead-acid batteries, to meet different requirements
6. Low voltage protection is with automatic adjustment of power protection value based on the size of the load, when the load current is large low-voltage protection value, when the load current is small, high-voltage protection value. Can effectively protect the battery life
7. Multistage battery status indicator, real-time display of battery power.
8. It comes with USB output port, USB 5V for mobile phones and digital products to charge or power, comes DC12V / 24V output port can be connected to DC12V / 24V bulb or fan power
9. Controller is with low power consumption.
10. The use of large caliber terminal 4mm2. Help users install wire
11. The controller uses a neutral packaging, suitable for export.
12. Using SMT chip production process, high quality PCB, industrial-grade chips, stable operation at high temperature, cold, humidity and other conditions.
13. Scientific rigor exterior design, the use of a high level of protection means, using pure aluminum pan to heat, more conducive to the life of the product..
