Mounting the Controller
Choose a vertical surface protected from direct sunlight, high temperatures, and water. Ensure good ventilation. The controller can be installed using either mounting holes or mounting brackets.
- Using Mounting Holes: Mark holes with the provided installation position guide. Fix screws at the marked positions. Align and mount the controller with the 4 pre-fixed screws.
- Using Mounting Brackets: Install the provided brackets to the controller. Mark holes with the four mounting brackets. Drill holes and insert plastic anchors (for drywall mounting). Fix the screws to the mounting brackets.

Visual guide for both mounting methods: direct screw-in via mounting holes or using the provided brackets.
Wiring Connections
Ensure all connections are secure and properly insulated. The controller features terminals for PV (solar panel), BAT (battery), and LOAD connections. Use the provided copper wire connectors and heat shrink tubing for robust and safe connections.
Connection Order:
- Connect the battery to the controller first.
- Connect the solar panel array to the controller.
- Connect the DC load to the controller (if applicable).
Always ensure correct polarity (+/-) to prevent damage to the controller or connected devices.
Operating Instructions
LCD Display and Indicators
The integrated LCD screen displays critical system information, including battery voltage, charging status, and load status. Multiple LED indicators provide quick visual cues for the state of the solar panel array, battery, loads, and controller faults.

The LCD screen provides detailed operational data, while LEDs indicate current charging mode, battery state, load status, and fault conditions.
Bluetooth Functionality
The built-in Bluetooth module allows for convenient remote monitoring and control via a smartphone app. Download the official LiTime app from your device's app store (Apple App Store or Google Play Store) to access detailed usage information and adjust parameters.

Monitor and control your MPPT controller remotely using the dedicated mobile application.
Battery Type Selection
The controller is pre-configured for LiFePO4 batteries, offering a plug-and-play experience for this battery type. For Sealed or Gel Lead-acid batteries, parameters can be adjusted through the controller's interface or the mobile app to ensure proper charging.

The controller is optimized for LiFePO4 batteries by default, but can be configured for other battery types.
Maintenance
To ensure the long-term performance and safety of your LiTime MPPT Solar Charge Controller, regular maintenance is recommended:
- Cleanliness: Keep the controller clean and free from dust and debris. Use a dry, soft cloth for cleaning.
- Ventilation: Ensure the cooling fins are not obstructed to allow for proper heat dissipation.
- Connections: Periodically check all wiring connections for tightness and signs of corrosion. Loose connections can lead to overheating and poor performance.
- Environmental Conditions: Ensure the controller remains within its specified operating temperature range and is protected from moisture.
Troubleshooting
If you encounter issues with your LiTime MPPT Solar Charge Controller, refer to the following common troubleshooting steps:
- No Display/Power: Check battery connections and ensure the battery voltage is within the controller's operating range. Verify solar panel connections and ensure sufficient sunlight.
- Low Charging Current: Inspect solar panels for shading or damage. Check all wiring for proper connection and gauge. Ensure battery parameters are correctly set for the battery type.
- Fault Indicators: Refer to the user manual for specific fault codes displayed on the LCD or indicated by LEDs. Address the underlying issue as per the manual's guidance.
- Bluetooth Connectivity Issues: Ensure Bluetooth is enabled on your mobile device and the app has necessary permissions. Try restarting the app and the controller.
For persistent issues, please contact LiTime customer support.
