( 5A, 12V/24V Output, Double Mode )
1. Introduction:
This controller is suitable for 12V and 24V solar photovoltaic system. The charge and discharge current is 5A. The maximum solar panel for 12V system is 90W/18V, for 24V system is 180W/36V.
This controller provides both manual control mode and light control mode. The manual control mode mainly for industrial, commercial, telecom, transportation and family solar energy system. The light control mode with automatic control for street lighting, parking lot lighting, bus station lighting, park lighting and garden lighting.
2. Characteristics:
a. Intelligent control, automatically identify the 12V and 24V output system. b. The light control mode has time controlled to delay and adjust lighting time. c. High reliability for lighting prompts, protections, alarm and set up instructions
with sound alarm.
3. Protections:
This controller has over charge, over discharge, battery reverse polarity, output short circuit, solar panel input short circuit and reverse polarity protections, and with sound alarm notice. Details are shown as follows:
Protection Descriptions Indication Overcharge Prevent battery overcharge, the battery automatically
convert to trickle charge after fully charged
Charging indicator light flashes quickly
Discharge Prevent battery excessive discharge, the effective protection of the battery
Audible alarm and LED indicate
Reverse battery Avoid improper operation to damage the battery All indicators are off
Output circuit short When the output current is > 1.5 times of rated current Audible alarm and LED indicate
Output over voltage When the output voltage is 10%> rated voltage Audible alarm and LED indicate
Solar panel input short circuit
Prevent the battery circuit short due to solar panels input suddenly circuit short.
Automatic processing by the controller
Reverse Solar Panel Input
Protect solar panel and battery Audible alarm
< Table 1 >
Note: For output short circuit protection, as long as protection occurred twice or more times at night, the controller will automatically turn off, no longer automatically recover until next night.
4. Operation Instructions:
The controller with dual-mode functionality. Respectively, the manual control mode and light control mode. The mode indicator is on when the manual control is set. The mode indicator is off when the light control mode is set. Two modes switch by pressing the setting button and hold it to 5 seconds, it will switch to the other mode.
5. The light control and manual control mode setting:
A. Light control mode settings
In light control mode, press the setting button and press the time in 0.1 - 2 seconds.
The delay time mode goes through ③②① three LED lights to indicate the
different combinations. Table II shows the corresponding modes (light on as a "

Note: a. The light control mode begins and scans from mode 1 to mode 7,
then repeated back to mode 1 and keep scanning.
b. Any excessive force may damage the setting button key
c. The light control mode relates to the output voltage of solar panel. When the voltage drop less than 2V for 12V system (4V for 24V system), the light control mode will turn on automatically. That means when the output voltage from solar panel drop at sunset, the voltage less than 2V, the light control mode will turn on. We can adjust the settings by customer’s request.
B. Manual control mode setting
In manual control mode, press the setting button, you can turn on or off the output. If the output short circuit or over current happened, the controller will automatically turn off the output, and audible alarmed. It will automatically recover after 6 seconds.

7. Installation:
a. Before installation, check the solar panel and battery. Make sure the voltage and
the size of load within the controller power range.
b. Connect the solar panel positive and negative outputs to the positive and negative (solar panel) inputs of controller.
c. Connect the battery positive and negative to the positive and negative (battery) input of controller.
d. Connect the positive and negative of load to the positive and negative of
controller.
e. Check all connections are correct and tied.
f. Check the output, battery and charging indicators are normal.
g. In accordance with the needs, set either manual or light control mode.

9. Trouble Shooting
Common Failures Fault Handling
Without any indications Battery power may reverse, check the battery is connected correctly
Connected solar panels to controller, the audible alarm rings 1 second every 6 seconds.
Check the polarity of solar panel on the controller
Battery indicator does not light Lack of electricity, it will automatic recovery until the battery is fully charged
After turn on the controller, the output immediately shut down and audible alarm
The output has short circuit, the problem will be solved after remove it
When the solar panel works under the Sun, the charging indicator is off
Check connections, it will automatically switch on after fully charged.
The controller occurs audible alarm and shut down output frequently
The controller output lines are short, and remove it.
Connected to 24V system, the battery indicator doesn’t work
Make sure the battery voltage > 20V.

10. Note:
1. Before use, make sure the battery voltage, solar panel voltage and load voltage fit to the controller.
2. The output voltage from controller is the same as voltage of battery, make sure the load voltage is complete match the battery voltage.
3. Use the proper wires for all connections.
4. To ensure good contact with solid wire, no short circuit and open circuit between the controller input and output lines.
5. To prohibit operating in the rain or soak in water in order to secure the system. 6. Non-exposure, don’t leave the controller directly under the Sun or in the very cold
temperature. It will reduce the life of controller.
7. To avoid the violent collision and vibration during transportation. 8. The controller may not access a variety of corrosive liquids and gases.
9. The controller will be generated certain heat in operating, it should provide sufficient space for heat dissipation.
