Model Number	CM2024Z	Application	Solar System Controller
Rated Voltage	24V	Maximum Current	20A

Product Description

CM2024Z-10A 20A

Sample Can be bought from Our Online Store:

/store/341515

Product Description

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.

LED Indication Instruction:

Icon	Indicator	State	Instruction
	Charging LED	off	not charging, no connecting of solar panels or weak sunshine
		on	charging, or elevated charging
		flickering	float charging, battery charged full
	Battery capacity LED	green led on	battery capacity full
		yellow led on	battery capacity normal
		red led on	battery capacity low
		red led flickering	low voltage protection for battery
	Load LED	on	load on
		off	load off
		flickering	Load closed, output overload or short-circuit.

Load Working Mode Instruction and Setting:

1. Normal mode: controller is used as PWM charging controller without lighting and timer function. Controller is at this mode without special request.

2. Lighting and timer controlling mode: At this mode, the controller will start the load after darkness and will close the load after setting hours (or sunrise).

3. Lighting control mode: At this mode, when the solar panels voltage is lower than 2.5V (for 24V system, 5V. for 48V system, 10V), controller will start the load after 10 seconds. When the solar panels voltage is higher then 3.5V (for 24V system, 7V. for 48V system, 14V), controller will close the load after 10 seconds.

FAQ

1. Load LED indicator flickering: the output of the controller is overload or short-circuit. After removing the redundant load, the controller will eliminate the overload protection within two minutes.

2. Charging LED indicator off: No connecting of the solar panels. Please check whether the connect is right and firm.

3. Battery capacity LED indicator off: Please check whether the connection of the solar panels, battery and load is right.
