20A 12V 24V PWM Solar charge controller with LCD, Data logger, programming, Auto Identification System &Temperature Compensation 

 

Part 1. Product Introduction

The CX series offers outstanding features in this class. In addition to sophisticated PWM charge regulation with integrated temperature compensation, the CX controllers provide substantial display, programming, and safety functions. The battery state of charge is clearly displayed by means of a bar graph, as well as energy flow from and to the battery and the load status (e.g. overload, load short circuit). 

 

The deep discharge protection function can be set to five different modes: two voltage-controlled, two SOC-controlled,

or one adaptive (battery deep discharge protection). Acoustic alarms are built in and a programmable nightlight function as well. The CX-DR can optionally be used for DIN rail mounting

Part 2. Product feature

>>Built-in 1 year data logger for system analysis

>>LC display

 >>Display indicates charge and discharge status, storage battery soc, load conditions

 >>Load disconnect prewarning by acoustic signal 

 >>Load status indication

 >>Choose among five load disconnect algorithms

 >>Four-stage PWM charging algorithm with integrated temperature compensation 

 >>Protected terminals (up to 16 mm2 wire size)

 >>Full electronic protection 

 >>Programmable nightlight function

Part 3. Protection function

>>Overvoltage protection: 

Battery voltage controlled, battery charge controlled, adaptive controlled. Five over discharge protection operation mode can be free setup of the three control modes.

>>Overvoltage protection: 15.5 V for 12V system, 31V for 24V system, 62V for 48V system

>>Undervoltage protection: 10.5 V for 12V system, 21V for 24V system, 42V for 48V system

>>Over curent protection

>>Short-circuit protection

>>Reverse polarity protection

>>Overtemperature protection
