What happens if my Epever Controller's lithium battery gets too cold?
If the temperature detected by the optional temperature sensor is below the low temperature threshold (LTPT) on your Epever Controller, the controller will automatically stop charging and discharging.
How to fix the charging LED indicator off during daytime when sunshine falls on PV modules properly on my Epever Controller?
If the charging LED indicator is off during the daytime when sunshine falls on PV modules properly, confirm that the PV wire connections are correct and tight.
What to do if the load and fault icon blink on my Epever Controller?
If the load and fault icon blink on your Epever Controller, it indicates a load short circuit. Carefully check the load connection, clear the fault, restart the controller, and wait for one night-day cycle (night time>3 hours).
What to do if the load has no output on my Epever Controller?
If the load has no output on your Epever Controller, it's likely due to a load overload. Reduce the number of electrical devices connected and restart the controller.
Why my Epever Controller shows system voltage error?
If there is a system voltage error on your Epever Controller, it means that the battery voltage does not match the controller's working voltage. Change to a suitable battery or reset the working voltage.
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.
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 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.
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.
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.
