4 Series 12.8V 14.4V 12V Lithium Iron Battery Phosphate Charger MPPT Solar Controller CN3722

Description:

Nominal 12V (12.8V) is full of junction termination voltage 14.4V    
 
4 lithium iron phosphate battery charging management board    
 
4A high current intelligent trickle, constant current, constant voltage charging management board    
 
Solar maximum power point tracking (MPPT)    
 
Solar maximum power point tracking (MPPT) is in order to ensure the change in the illumination intensity, the photovoltaic battery has been the maximum output of solar energy. In general, the DC-DC converter is required to realize the MPPT function with the switch mode, and the output voltage and the product of the charge current (output power) are maximized,    
 
CN3722 is the switch buck mode DC-DC converter for photovoltaic maximum power point tracking function, the input voltage up to a maximum of 28V, very suitable for input voltage and the voltage of the battery application of relatively large difference.    
 
Charging management board features:    
- High-end technology MPPT solar maximum power tracking charging management chip, with a trickle, constant current, constant voltage charging management    
- The imported high frequency low pass impedance double MOS tube, the high current diode, efficient, flat power inductor, alloy current sense resistor    
- The bottom of the large aluminum fins, to ensure the large current time and time to work stably    
- High efficiency charging mode    
- Double status indicator, when no battery, the red light flashing green light, when charging, red light, when full of electricity, automatic stop, while the green light.
