CM20

20A 12V/24V Solar Charge Controller

 

CM Series Controller Has Following Features:

1.Intuitionistic LED indicators show the current system battery capacity, charging and discharging state of the battery.                                                                                     

2. Having the protection functions as overcharging, over discharging, overload, short-circuit and reversed connection.                                                                                         

3. Tandem type PWM charging makes the charging efficiency increase by 3% to 6%, compared with non-PWM charging.                                                                                               

4.The parameters of charging and discharging have been set during the production(special parameters need to be told in advance), so no need to adjust the parameters.                                                               

5.It can set the working mode of the load.                                                                

6.USB charging function (optional).                                                                     

7. Grid-complementary(optional function)                                                                     

8.remote telecommunications function equipped(optional function).                                                

9.Prevent battery from discharging to battery at night.  

You can View and Set the Parameters:

1.Battery Voltage
2.The load on/off control
3.Environment Temperature
4.Solar Panel charging current
5.Load discharging current
6.Accumulated charging power (Ah) by solar panel and back to zero
7.Accumulated discharging power (Ah) by Load and back to zero
8.Low Voltage Disconnection Protection
9.Low Voltage Reconnection
10.High Voltage Disconnection

Three Load Working Mode:

24H—Normal Mode, in case of no fault state of the load is always in power.
1H~23H—Light Control with Time Control Mode, Load power after dark, and close the load according to the timer setting.
0H—Light Control Mode, Load on after dark, turn off the load after drawn.
