What happens if I reverse the battery polarity on my Epever Controller?
The Epever Controller is fully protected against reversed battery polarity. To restore normal operation, switch to the correct polarity.
How to fix the charging LED indicator off during daytime when sunshine falls on PV modules properly on my Epever XTRA4210N?
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 my Epever Controller shows Load Overload?
If your Epever Controller indicates a Load Overload, try reducing the number of connected electrical devices. Then, restart the controller and wait for a complete night-day cycle (with nighttime lasting more than 3 hours).
What to do if my Epever XTRA4210N indicates a Load Short Circuit?
If your Epever Controller displays a Load Short Circuit error, carefully inspect the load connections and fix any faults. After correcting the issue, restart the controller and allow it to cycle through one complete night-day period (with nighttime exceeding 3 hours).
What happens if my Epever XTRA4210N Controller is overheating?
If the Epever Controller's heat sink temperature exceeds 85 degrees Celsius, it will automatically cut off the input and output circuits. Normal operation will resume once the temperature drops below 75 degrees Celsius.
What happens if the battery is too low on my Epever XTRA4210N 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 XTRA4210N Controller 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 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.
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 to do if the load has no output on my Epever XTRA4210N 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.
