Important Safety Instructions
- Ensure all wiring is correctly connected before powering on the controller. Incorrect wiring can damage the device and connected components.
- Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order.
- Install the controller in a well-ventilated area, away from direct sunlight, high temperatures, and moisture.
- Do not attempt to disassemble or repair the controller yourself. Contact qualified personnel for service.
- Use appropriate wire gauges for connections to prevent overheating and power loss.
- Ensure the battery voltage matches the controller's system voltage (12V or 24V).
- Keep children away from the solar power system components.

- Connect the Solar Panel: Connect the positive and negative terminals of your solar panel(s) to the corresponding solar panel terminals on the controller. Ensure correct polarity.
- Connect the DC Load (Optional): Connect the positive and negative terminals of your DC load to the corresponding load terminals on the controller. Ensure correct polarity.
Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.
Operating Instructions
LCD Display Overview
The LCD display provides real-time information about your solar power system. Key indicators include:
A clear view of the solar controller's front panel, with the LCD display showing various operational parameters such as voltage and battery status.
- Battery Voltage: Displays the current voltage of the battery bank.
- Charging Current: Shows the current flowing from the solar panel to the battery.
- Discharging Current: Indicates the current drawn by the DC load.
- Temperature: Displays the internal temperature of the controller.
- Battery Status Icon: Illustrates the battery charge level.
- Solar Panel Icon: Indicates if solar charging is active.
- Load Icon: Shows if the DC load is active.
Button Functions
The controller has three buttons for navigation and settings adjustment:
- Menu Button (Left): Press to cycle through display modes and enter/exit setting menus.
- Up Button (Middle): Used to increase values or navigate upwards in menus.
- Down Button (Right): Used to decrease values or navigate downwards in menus.
Parameter Settings
To adjust charging and discharging parameters:
- Press the Menu button until you reach the desired parameter setting screen (e.g., over-discharge voltage, charge recovery voltage).
- Press and hold the Menu button for a few seconds until the displayed value starts flashing.
- Use the Up and Down buttons to adjust the value.
- Press the Menu button again to confirm the setting and exit the flashing state.
USB Charging
The dual USB output ports provide 5V, 2.5A (max) for charging mobile devices. Simply connect your USB charging cable to the controller's USB port and your device.

Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your solar controller.
- Cleaning: Periodically clean the controller's exterior with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners.
- Connections: Annually check all wiring connections for tightness and corrosion. Loose connections can cause resistance and heat buildup.
- Ventilation: Ensure the installation area remains well-ventilated and free from obstructions to allow proper heat dissipation.
- Inspection: Visually inspect the controller for any signs of damage, discoloration, or unusual odors.
Troubleshooting
If you encounter issues with your Srliya Solar Controller, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on / LCD blank | Battery not connected or low voltage; reverse polarity. | Check battery connections and voltage. Ensure correct polarity. Charge battery if critically low. |
| No charging current from solar panel | Solar panel not connected; insufficient sunlight; reverse polarity; damaged panel/wiring. | Check solar panel connections and polarity. Ensure adequate sunlight. Inspect panel and wiring for damage. |
| Load not working | Load not connected; over-discharge protection active; load overcurrent; reverse polarity. | Check load connections and polarity. Verify battery voltage is above over-discharge threshold. Reduce load if current exceeds controller rating. |
| USB ports not charging | Battery voltage too low; device not compatible; faulty USB cable. | Ensure battery is sufficiently charged. Try a different USB cable or device. |
| Controller overheating | Poor ventilation; excessive load/charging current. | Ensure proper airflow around the controller. Reduce load or check for short circuits. |
