What happens if I reverse the battery polarity on my Epever XTRA4415N Controller?
The Epever Controller is fully protected against reversed battery polarity. To restore normal operation, switch to the correct polarity.
What happens if the battery is too low on my Epever Controller?
When the battery voltage reaches the undervoltage disconnection voltage, the battery discharge is automatically stopped to avoid damage to the battery caused by excessive discharge.
What to do if the battery voltage is lower than 8V on my Epever Controller?
If your Epever Controller isn't working and the battery voltage is lower than 8V, even with correct wiring, ensure that the battery has at least 8V to activate the controller.
What happens if my Epever XTRA4415N experiences battery overvoltage?
When the battery voltage reaches the over-voltage disconnect voltage on the Epever Controller, the battery charging will automatically stop. This prevents damage to the battery that could be caused by over-charging.
How to fix the charging LED indicator if it's off during the daytime on my Epever Controller?
If the charging LED indicator is off during the daytime when sunshine falls on PV modules properly, confirm that PV wire connections are correct and tight.
What to do if my Epever XTRA4415N is not working, even though the wire connection is correct?
If your Epever Controller is not working despite correct wire connections, the battery voltage may be too low. Ensure the battery voltage is at least 8V to activate the controller.
What does it mean when the battery indicator is red slow flashing on my Epever Controller?
If the battery indicator on your Epever Controller is flashing red slowly, it indicates the battery is overheating. The controller will automatically turn the system off. When the temperature declines to be below 55 degrees Celsius, the controller will resume.
What does it mean when the battery indicator is red on solid on my Epever XTRA4415N Controller?
If the battery indicator on your Epever Controller is solid red, it means the battery is over-discharged. When the battery voltage is restored to or above LVR (low voltage reconnect voltage), the load will recover.
Why is the PV/BATT(orange)/Battery capacity lever(four) indicator fast flashing on my Epever XTRA4415N Controller?
If the PV/BATT(orange)/Battery capacity lever(four) indicator is fast flashing on your Epever Controller, it indicates the controller is overheating. The controller will automatically cut off the input and output circuit when the heat sink exceeds 85 degrees Celsius. It will resume work when the temperature drops below 75 degrees Celsius.
What does it mean when the charging indicator is green fast flashing on my Epever Controller?
If the charging indicator on your Epever Controller is flashing green rapidly, it signifies a battery over voltage. Check if the battery voltage is higher than OVD (over voltage disconnect voltage), and disconnect the PV.
