2. Safety Information
- Ensure all connections are correct and secure before operation. Incorrect wiring can damage the controller and connected devices.
- Always connect the battery to the charge controller FIRST, then the solar panel, and finally the load. When disconnecting, reverse this order: disconnect the solar panel, then the load, then the battery.
- This controller is designed for 12V/24V lead-acid batteries (OPEN, AGM, GEL). It is NOT suitable for Ni-MH, Lithium, or other battery types unless explicitly stated in the settings.
- Install the controller in a well-ventilated area, away from flammable materials and moisture.
- Avoid short circuits. Ensure all wires are properly insulated and terminals are tightened.
- Do not attempt to disassemble or repair the controller yourself. Contact qualified personnel for service.
3. Product Features
- 60A PWM Controller: Full 3-stage PWM management (direct charge, boost charge, float charge) for enhanced system efficiency and extended battery life.
- Multiple Protection: Built-in overcurrent/overload, open circuit, and reverse polarity protection. All protections are self-recovering.
- Functional LCD Display: Clear display shows status and data, allowing mode switching and parameter configuration.
- Battery Compatibility: Suitable for 12V/24V lead-acid batteries (OPEN, AGM, GEL).
- Dual USB Ports: Two 5V/2A USB ports for charging mobile phones and other 5V devices.
- Automatic Identification: Automatically recognizes 12V or 24V system voltage.

5. Setup and Installation
Follow these steps carefully to ensure proper and safe installation of your solar charge controller.
5.1. Connection Order
- Connect the Battery: Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -).
- Connect the Solar Panel: Connect the solar panel to the charge controller. Ensure correct polarity.
- Connect the Load: Connect your DC load (e.g., lights, 5V USB devices) to the charge controller. Ensure correct polarity.
WARNING: Always follow the connection order (Battery > Solar Panel > Load) and disconnection order (Solar Panel > Load > Battery) to prevent damage to the controller.

6. Operating Instructions
The Anern 60A PWM Solar Charge Controller features an intuitive LCD display and three buttons for easy operation.
6.1. LCD Display Overview
Image 6.1: Detailed view of the LCD display area, voltage symbol, HR, panels, five-battery level indicator, load identification, charging logo, and output identification. Also shows the MENU, UP, and DOWN/HM buttons.
- Digital Display Area: Shows various parameters like voltage, current, and settings.
- Voltage Symbol: Indicates voltage readings.
- HR: Timer setting for load control.
- Panels: Indicates solar panel activity.
- Five Battery Level Indicator: Shows the current battery charge level.
- Load Identification: Indicates if a load is connected and active.
- Charging Logo: Continuous lighting for direct charging/charging, slow flashing for floating loading.
- Output Identification: Indicates load output status.
6.2. Button Functions
- MENU Button: Press to browse different interfaces. Press and hold for five seconds to enter or exit parameter settings.
- UP Button: Press to increase the value during parameter settings.
- DOWN/HM Button: Press to decrease the value during parameter settings.
6.3. Parameter Settings
To configure parameters, navigate through the display interfaces using the MENU button. When on the desired parameter screen (e.g., battery type, float voltage), press and hold the MENU button for five seconds to enter the setting mode. The number will flash, allowing adjustment with the UP and DOWN buttons. Press and hold MENU again for five seconds to save and exit.

- Default Settings: The controller comes with factory default settings for charging and discharging. You can restore these by pressing and holding the UP button for five seconds on interfaces 2-5.
- Battery Type: Select the correct battery type (e.g., GEL, AGM, OPEN) to ensure proper charging algorithms.
- Float Voltage: The voltage at which the battery is maintained after being fully charged.
- Discharge Reconnect: The voltage at which the load will reconnect after being disconnected due to low battery.
- Discharge Stop: The voltage at which the load will disconnect to protect the battery from over-discharge.
- Working Methods: Configure load control modes (e.g., 24H for continuous operation, timer settings).
6.4. Dual USB Ports
The controller is equipped with two 5V/2A USB ports, allowing you to charge compatible mobile phones and other 5V devices directly from the controller.
7. Maintenance
- Regularly check all wiring connections for tightness and corrosion.
- Keep the controller clean and free from dust and debris.
- Ensure adequate ventilation around the controller to prevent overheating.
- Monitor the LCD display periodically to ensure correct operation and parameter settings.
8. Troubleshooting
| Situation | Probable Cause | Solution |
|---|---|---|
| Charge not on or load not on when sunny | Solar panel open or reversed | Check connections |
| Load not on when sunny | Mode setting wrong | Set again |
