How to fix the Epever Controller charging LED indicator when it's off during the daytime with proper sunshine on the PV modules?
If the charging LED indicator is off during the daytime when sunshine falls on PV modules properly, confirm that the PV and battery wire connections are correct and tight.
What to do if the Epever Controller load has no output and the load/fault icon blink?
If the load has no output and the load/fault icon is blinking on your Epever Controller, it indicates a load overload. Reduce the number of connected electrical devices, restart the controller, or wait for one night-day cycle (night time > 3 hours).
Why does the Epever Tracer3210AN Controller battery level show full, with the battery frame and fault icon blinking?
If the battery level on your Epever Controller shows full, but the battery frame and fault icon are blinking, it signifies a battery over voltage. Check if the battery voltage exceeds the OVD (over voltage disconnect voltage) and disconnect the PV.
What to do if there is a Load Short Circuit on the Epever Tracer3210AN?
If there is a load short circuit, carefully check the load connections and clear the fault. Restart the Epever Controller and wait for one night-day cycle (night time > 3 hours).
What does it mean when the Epever Tracer3210AN Controller battery level is empty, battery frame blinks, and fault icon blinks?
When the battery level shows empty, the battery frame blinks, and the fault icon blinks on the Epever Controller, it indicates that the battery is overheating. The controller will automatically turn the system off. The controller will resume once the temperature declines below 55 ºC.
Why is my Epever Tracer3210AN not working even though the wire connections are correct?
If your Epever Controller is not working despite correct wiring, the battery voltage may be too low. Check the battery voltage; it needs to be at least 8V to activate the controller.
What to do if Epever Tracer3210AN Controller shows overload?
If your Epever Controller indicates an overload, reduce the number of connected electrical devices. Then, restart the controller or press the button to clear the fault.
What to do if Epever Controller has load short-circuit?
If the Epever Controller displays a load short-circuit, carefully check the load connections and clear the fault. Then, restart the controller or press the button to clear the faults.
What to do if Epever Tracer3210AN indicates battery over discharged?
If your Epever Controller indicates that the battery is over discharged, the load will recover when the battery voltage is restored to or above the LVR (low voltage reconnect voltage). In the meantime, use alternative methods to recharge the battery.
How to fix PV array open-circuit on Epever Controller?
To address a PV array open-circuit issue with your Epever Controller, verify that the PV array connections are correct and securely tightened.
