Description: The large screen LCD shows that the parameters of charging and discharging can be adjusted. Complete 3 stage PWM charging management. Built-in over-current/short-circuit protection, open-circuit protection, reverse protection, are automatic recovery type, do not damage the controller. Double MOS anti backflow circuit has extremely low calorific value. Easy to set up and operate. suitable for home, industrial, commercial, etc. Specification: Material: ABS Rated Voltage: 12/24V Rated Current: 60A Charge Mode: PWM Function: 1. Always keep the battery on fill voltage condition. 2. Prevent the battery from over-charging. 3. Prevent the battery from over-discharging. 4. Prevent the battery from reverse charging to solar panels during nights. 5. Reverse polarity protection for battery 6. Reverse polarity protection for solar panels 7. When the battery voltage is low, the controller will automatically cut off the load from the system. If the voltage of battery is back to normal and the load will restart working. 8. Thunder protection 9. According to the battery voltage grade, the controller can automatically set charge-off voltage, the load-off voltage, the load- restore voltage. 10. The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.
