It incorporates quick charge technology to handle high power demands and offers comprehensive protection against overcharge, over-discharge, overload, low voltage, short circuit, and reverse connection. The humanized backlight LCD display and dual button operation provide a user-friendly interface, especially in low-light conditions.
2. Safety Information and Precautions
WARNING: Solar panel voltage can be very high under sunlight, which may cause injury or damage to the controller. Always connect loads to the controller correctly. For 48V systems, reverse connection of the solar panel will destroy the solar charge controller.
To prevent injury from load voltage, always disconnect the load from the controller using the button first before connecting or disconnecting the physical load wires to prevent damage. This controller does not offer reverse connection protection for the load, and incorrect connection can damage connected devices (e.g., destroy a bulb).
- Ensure all connections are secure and correct before applying power.
- Do not expose the controller to water or excessive moisture.
- Install in a well-ventilated area to prevent overheating.
- Keep out of reach of children.

4. Setup and Installation
Proper wiring is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully:
- Connect the Battery: First, connect the battery to the charge controller's battery terminals (marked "BATT"). Ensure correct polarity (+ to + and - to -). The controller will automatically detect the 12V or 24V system voltage.
- Connect the Solar Panel: Next, connect the solar panel to the charge controller's PV terminals (marked "PV"). Ensure correct polarity.
- Connect the Load: Finally, connect your DC load to the charge controller's load terminals (marked "LOAD"). Ensure correct polarity. Remember to disconnect the load using the controller's button before connecting or disconnecting the physical load wires to prevent damage.

Always ensure all connections are tight and secure to prevent loose contacts and potential hazards.
5. Operating Instructions
The SolaMr ST6-60A controller is designed for ease of use with its intuitive LCD display and two-button interface.
- LCD Display: The backlight LCD displays real-time system parameters such as battery voltage, charging status, and load status. The backlight ensures visibility in various lighting conditions.
- MENU Button: Press the "MENU" button to cycle through different display screens and access settings.
- ON/OFF Button: Use the "ON/OFF" button to control the load output. Press it to toggle the load on or off. This button is also used to confirm selections within the menu.
- Setting Parameters: To adjust parameters like load control mode or time functions, navigate through the menu using the "MENU" button and confirm changes with the "ON/OFF" button. Refer to the on-screen prompts for specific adjustments.
- USB Charging: The dual 5V USB ports provide power for charging compatible electronic devices. Simply plug your device's USB cable into one of the ports.
6. Maintenance
To ensure the longevity and optimal performance of your SolaMr solar charge controller, consider the following maintenance tips:
- Regular Cleaning: Periodically wipe down the controller with a dry, soft cloth to remove dust and debris. Ensure the LCD screen remains clear for readability.
- Check Connections: Annually inspect all wiring connections (PV, Battery, Load) to ensure they are tight and free from corrosion. Loose connections can lead to power loss or overheating.
- Ventilation: Ensure the installation area remains well-ventilated to allow for proper heat dissipation from the controller. Avoid blocking the ventilation holes.
- Environmental Conditions: Protect the controller from direct exposure to extreme temperatures, moisture, and corrosive environments.
7. Troubleshooting
While the SolaMr ST6-60A controller is designed for reliability, here are some general troubleshooting tips for common issues:
- Controller Not Powering On:
- Check battery connections. Ensure the battery is connected first and has sufficient voltage.
- Verify battery polarity. Reverse polarity can prevent the controller from powering on or cause damage.
- Battery Not Charging:
- Check solar panel connections and polarity.
- Ensure there is sufficient sunlight reaching the solar panels.
- Verify the solar panel's open circuit voltage is within the controller's acceptable range.
- Load Not Working:
- Check load connections and polarity.
- Ensure the load output is enabled via the ON/OFF button.
- Verify the battery has enough charge to power the load. The controller will cut off load output if battery voltage is too low.
- Check for overload conditions. If the load current exceeds the controller's rating, the output may be shut off.
- LCD Display Issues:
- If the display is dim or flickering, check battery voltage.
- Ensure the controller is receiving power.
For more complex issues or if troubleshooting steps do not resolve the problem, please contact SolaMr customer support.
