1. Introduction
The MECCANIXITY MPPT Solar Charge Controller is designed to optimize the energy utilization efficiency of photovoltaic systems. It features a built-in maximum power tracking program to ensure your solar panels operate at their peak output point. This intelligent regulator is suitable for 12V/24V auto-adaptive systems and includes an LCD display for monitoring and configuration, along with dual USB ports for convenience.
2. Safety Information
- Ensure the battery has sufficient voltage for the controller to recognize the correct battery type during first use.
- Only use photovoltaic panels as a charging source. Do not connect DC or other power sources.
- Always connect the battery to the charge controller first, then connect the solar panel. When disconnecting, disconnect the solar panel first, then the battery.
- Ensure all wiring connections are secure and properly insulated to prevent short circuits or damage to equipment.
- Avoid touching bare wires. If necessary, use electrical tape to cover exposed wire ends.

Installation Steps:
- Connect the Battery: Connect the battery to the charge regulator's positive and negative terminals first. Ensure correct polarity.
- Connect the Solar Panel: Connect the photovoltaic module (solar panel) to the charge regulator's positive and negative terminals.
- Connect the Load: Connect the consumer (load) to the charge regulator's positive and negative terminals.
Important: Always connect the battery first and disconnect the solar panel first to prevent damage to the controller.

5. Operating Instructions
LCD Display and Button Functions:
The LCD display provides real-time information about your solar system. The control buttons (Menu, Page Up, Page Down/Manual) allow you to navigate through different screens and adjust parameters.
- Main Display: Shows current battery voltage and charging status.
- Float Voltage: Displays the voltage at which the battery is maintained after full charge (e.g., 13.7V for 12V systems).
- Discharge Reconnect: The voltage at which the load will be reconnected after being disconnected due to low battery (e.g., 12.6V for 12V systems).
- Discharge Stop: The voltage at which the load will be disconnected to protect the battery from over-discharge (e.g., 10.7V for 12V systems).
- Battery Type: Allows selection of battery type (e.g., Sealed, Gel, Flooded).
- Work Mode: Configures load output modes (e.g., 24-hour output, dusk-to-dawn, timed output).
Press the 'Menu' button to cycle through different display interfaces. Use the 'Page Up' and 'Page Down/Manual' buttons to adjust settings when in configuration mode (typically by long-pressing the 'Menu' button to enter setting mode).
6. Maintenance
- Regularly check all wiring connections for tightness and corrosion.
- Keep the controller clean and free from dust and debris to ensure proper heat dissipation.
- Ensure adequate ventilation around the controller.
- Monitor the LCD display for any error codes or unusual readings.
7. Troubleshooting
Common Issues and Solutions:
- No Display/No Power: Check battery connections and voltage. Ensure the battery has sufficient charge.
- Battery Not Charging: Verify solar panel connections and ensure adequate sunlight. Check for shading on solar panels. Confirm correct battery type setting.
- Load Not Working: Check load connections. Ensure the battery voltage is above the discharge reconnect voltage. Verify load work mode settings.
- Over-voltage/Over-current Protection: The controller will automatically disconnect to protect the system. Identify the cause (e.g., too many solar panels, incorrect battery voltage) and rectify it before restarting.
