2. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Always connect the battery first to ensure proper voltage detection and protection. For safety, circuit breaker connections are recommended for all circuits.
2.1 Connection Steps
- Connect the Battery: Connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12V/24V).
- Connect the Load: Connect your DC loads to the controller's load terminals. Ensure correct polarity.
- Connect the Solar Panel (PV array): Connect the solar panel to the controller's PV terminals. Ensure correct polarity.
Important Safety Note: Always connect the battery first and disconnect the solar panel last during uninstallation. Do not use an electric screwdriver for connections to avoid overtightening.

3.1 Monitoring
The MT50's monitoring screen displays real-time data such as PV voltage/current, battery voltage/current, and load voltage/current. You can navigate through different screens using the arrow buttons.
3.2 Setting Parameters
The MT50 allows you to customize various parameters, including battery type and load working mode. For lithium batteries, manual voltage settings are required as the controller does not automatically identify their system voltage.
To set parameters:
- Choose "Control para" from the menu.
- Press "OK".
- Press "OK" again.
- Set parameters (for lithium battery, select "User" and input specific values). Press "OK" to save.
- Continue setting other parameters as needed.
Note: Lithium batteries do not automatically identify system voltage. In "Rated Voltage", please select 12V or 24V for your lithium battery system. Please set the parameters under the guidance of professionals, referring to the detailed settings in the manual for your specific battery type (Li-NiCoM or LiFePO4).
Load working modes can also be set via the MT50, including Manual Control, Light On/Off, Light On+Timer, and Time Control. Refer to the manual for detailed settings on pages 21-23.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your EPEVER solar charge controller.
- Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Loose connections can cause overheating and damage.
- Clean the Controller: Keep the controller's heat sink and casing clean from dust and debris to ensure efficient heat dissipation. Use a dry cloth for cleaning.
- Inspect Wiring: Check for any signs of wear, fraying, or damage to the cables. Replace damaged cables immediately.
- Battery Health: Monitor your battery's health and ensure it is within its recommended operating parameters.

5. Troubleshooting
If you encounter issues with your solar charge controller, refer to the following common problems and solutions:
- No Power/Display: Check battery connections and ensure the battery has sufficient charge. Verify all wiring is correct and secure.
- No Charging: Ensure solar panels are receiving adequate sunlight. Check PV connections and polarity. Verify PV voltage is within the controller's operating range.
- Load Not Working: Check load connections and ensure the load is not exceeding the controller's rated current. Verify load working mode settings on the MT50.
- LED Indicators: Refer to the LED indicator table in the manual for specific status and error codes. For example, a fast flashing PV LED might indicate PV overvoltage, while an orange solid BATT LED indicates undervoltage.
- Battery Overheating: Ensure the controller is installed in a well-ventilated area. Check the ambient temperature and ensure the battery is not being overcharged (verify settings).
