5. Setup and Installation
Follow these steps for proper installation. Always ensure correct polarity and secure connections to prevent damage.
Connect the Battery: Loosen the screws on the battery terminals of the controller. Connect the positive (+) and negative (-) battery cables to the corresponding terminals. Ensure the connection is secure. The controller will automatically detect the system voltage (12V/24V).
Connect the Load: Loosen the screws on the load terminals. Connect the positive (+) and negative (-) load cables to the corresponding terminals.
Connect the Solar Panel: Loosen the screws on the solar panel (PV) terminals. Connect the positive (+) and negative (-) solar panel cables to the corresponding terminals.
Connect Temperature Sensor (Optional): Insert the remote temperature sensor into the designated port on the controller. This allows for accurate battery temperature compensation during charging.
Important: Always connect the battery first, then the load, and finally the solar panel. When disconnecting, reverse this order: disconnect the solar panel, then the load, and finally the battery.

6.3 Setting Load Working Mode
To set the load working mode:
Press the "ENTER" button and hold for 5 seconds under the load mode interface.
Press the "SELECT" button when the load mode interface is flashing to choose the desired mode.
Press the "ENTER" button to confirm the load mode.
Caution: Setting Light ON/OFF, Test mode, and Manual mode via Timer1. Timer2 will be disabled and display "2n".
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your solar charge controller. Perform the following checks periodically:
Clean the Controller: Keep the controller clean and free from dust and debris. Use a dry cloth to wipe the surface.
Check Connections: Periodically inspect all wiring connections (solar panel, battery, load) to ensure they are tight and free from corrosion. Loose connections can cause overheating and damage.
Inspect for Damage: Check for any visible signs of damage to the controller, cables, or terminals.
Verify Ventilation: Ensure that the controller's heat sink and ventilation openings are not blocked to allow for proper heat dissipation.
8. Troubleshooting
If you encounter issues with your EPEVER Tracer4210AN, refer to the following general troubleshooting tips. For detailed error codes and solutions, consult the full user manual provided with the product.
No Display/Power: Check battery connections and ensure the battery has sufficient voltage. Verify all fuses in the system.
No Charging: Ensure solar panels are connected correctly and receiving sunlight. Check PV voltage and current on the LCD. Verify battery type settings.
Load Not Working: Check load connections and ensure the load is within the controller's rated current. Verify load working mode settings.
Over-voltage/Under-voltage Alarms: Check battery voltage and ensure it is within the safe operating range for the selected battery type.
The controller has multiple built-in protections (PV over-voltage, battery over-voltage, over-temperature, over-charging, short-circuit, reverse polarity) which may activate to protect the system. If a protection is triggered, the LCD may display an error code or indicator. Address the underlying cause before resetting or restarting the system.
