5. Installation

5.1 Instruction Notes

CAUTION: Please use only the provided screws. Using other screws may damage the internal PCB. Apply proper torque when pushing screws into the casing to avoid damaging the internal PCB.

Connections must always be made in the sequence described below:

1. 1st step: Connect the batteries
   Connect the battery connection cable with the correct polarity to the middle pair of terminals on the solar charge controller (marked with the battery symbol). If the system is 12V, ensure your battery voltage is more than 12V for the controller to boot up.
2. 2nd step: Connect the solar panel
   Ensure that the PV modules are protected from incident light. Ensure the solar panel doesn't exceed the maximum permissible input current. Connect the PV modules connection cable to the correct polarity of the left pair of terminals on the solar charge controller (marked with the PV modules symbol).
3. 3rd step: Connect loads
   Connect the load cable to the correct polarity of the right pair of terminals on the solar charge controller (marked with the lamp symbol). To avoid any voltage on the wires, connect the wire to the load before connecting to the controller.
4. 4th step: Final worked
   Tighten all cables connected to the controller and remove all debris around the controller (leaving a space of approx. 5.91 inches).

NOTE: When the reading data of PV or battery is constantly changing, don't worry about it. The controller is finding the Maximum Power Point (MPP). This is caused by your PV input power or voltage not being stable enough. If issues persist, please contact our technological team for assistance.

5.2 Air Circuit Breaker Installation

We strongly recommend connecting a fuse directly to the battery to protect against any short circuit at the battery wiring. Solar PV modules generate current whenever light strikes them. The current varies with light intensity, but even at low light levels, full voltage is given by the modules. Therefore, protect the solar modules from incident light during installation. Never touch uninsulated cable ends, use only insulated tools, and ensure the wire diameter is in accordance with the expected currents of the solar charge controller.

Air Circuit Breaker and Wires Requirement:

5.3 Connection Steps with Air Circuit Breakers

It's better to connect two wires to two PV+ and another two wires to two PV-. For BAT+ and BAT-, it's the same way to connect wires.

1. Install air circuit breaker between controller and batteries. Turn off the circuit breaker, then connect batteries to controller with correct polarity.
2. Install air circuit breaker between controller and PV modules. Turn off the circuit breaker, and ensure the PV polarity is correct, then connect wires between PV modules and controller.
3. Turn on the air circuit breaker between controller and batteries.
4. Turn on the air circuit breaker between controller and PV modules.
5. The controller goes into self-test mode. Its LCD displays parameters if all is correct. The RUN lamp (under the fan inside the casing) will flash every one second. If the controller does not respond, please read the full manual again for reinstallation or contact us for help.

6. Operation

6.1 LCD Display and Main Interface

The LCD display provides real-time information about the system's status. The main interface cycles through PV voltage/output power, battery voltage/charging current, working mode/temperature, and fault code.

Main Interface Item Description:

6.2 Working Modes

The controller operates in different working modes:

6.3 Button Functions

6.4 Manual Settings

Reminder: The controller will work fine under default settings except for lithium batteries.

CAUTION: All steps must be carried out when the PV modules are disconnected from the controller.

Step 1: D00 (Load Working Time)

• Press the PRG button until the LCD displays D00. This sets the load working time (Default is 24-hour).
• Press ENT until numbers flash, then use UP/DOWN to set the desired time.
• Long-press ENT to confirm. This output voltage is the same as the battery. The load is only for small DC loads less than 5A current. If no load, leave it.

Step 2: D01 (Floating Charging Voltage)

• Press the UP button, LCD shows 13.8 (default value for floating charging).
• Press ENT until numbers flash, then use UP/DOWN to set the desired voltage.
• Long-press ENT to confirm.

CAUTION: This value is for one 12V battery. If there are multiple batteries in series, the controller will automatically multiply them proportionally, and the LCD will only display the voltage of one battery (e.g., for 4x12V, if you set 14.1V, the charge voltage will be 4x14.1V, but the LCD will only display 14.1V).

Step 3: D02 (Absorption Charging Voltage)

• Continue to press the UP button, LCD shows 14.5 (highest absorption charging voltage for battery).
• Press ENT until numbers flash, then use UP/DOWN to set the desired voltage.
• Long-press ENT to confirm.

CAUTION: This value is for one 12V battery. If there are many batteries in series, the controller will multiply them in proportion automatically and the LCD only displays the voltage of one battery.

Step 4: D03 (Battery Discharge Protection Voltage)

• Continue to press the UP button, LCD shows 10.0. This is the protection value for battery discharge.
• Press ENT until numbers flash, then use UP/DOWN to set the desired voltage.
• Long-press ENT to confirm. This means it's protected when a 12V battery is less than 10.0V, and there is no output power from OU+ and OU-.

Step 5: D04 (Battery Voltage Calibration)

• Continue to press the UP button, LCD shows C12.2. This setting calibrates the battery voltage, ensuring the voltage detected by the controller matches the actual battery voltage.

Step 6: D05 (Battery Type Setting)

• Continue to press the UP button, LCD shows the setting program for battery type. The default option is USE.

Available Battery Types:

CAUTION: When selecting the options of SEL, GEL, and FLd battery types, the controller can automatically detect the system voltage.

Step 7: D06 (User-defined System Voltage)

• If you choose the USE option in the D05 battery type setting, you will need to manually configure the system voltage in the D06 setup program. The configuration range is 12V/24V/36V/48V.

Exiting Settings:

• Press ESC to exit the setting menu.

Reminder: When you set up all steps, please disconnect the battery. Then reconnect the controller to see if all settings are successful. Once all settings are confirmed, then connect the PV modules to the controller.

7. Troubleshooting and Protections

7.1 Troubleshooting Guide

7.2 Protections

1. PV Over Current: The controller will limit charging power to the rated charge power. An over-sized PV array will not operate at maximum power point.
2. PV Short Circuit: When a PV short circuit occurs, the controller will stop charging. Remove the short circuit to resume normal operation.
3. PV Reverse Polarity: Fully protected against PV reverse polarity, no damage to the controller. Correct the connection to start normal operation.
4. Battery Over Voltage: If there are other energy sources charging the battery, and the battery voltage exceeds 15.5V (for 12V system), 31.0V (for 24V system), 46.5V (for 36V system), or 62.0V (for 48V system), the controller will stop charging to protect the battery from overcharging damage. (Note: Stop charging means the charging current is very low).
5. Battery Over Discharge: When battery voltage drops to the setting voltage point of low voltage disconnect, the controller will stop discharging to protect the battery from over-discharging damage.
6. Load Over Current Protection: If the load current exceeds 1.25 times the maximum load current rating, the controller will disconnect the load.
7. Load Short Circuit Protection: Once a load short circuit happens, the Load Short circuit protection will start automatically.
8. Over Temperature Protection: The fan will activate to reduce temperature automatically if the controller overheats.
