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 happens if my Epever XTRA N 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 XTRA N 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 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 I reverse the battery polarity on my Epever XTRA N?
The Epever Controller is fully protected against reversed battery polarity. To restore normal operation, switch to the correct polarity.
Why is my Epever Controller showing PV excess current or power?
If the charging current or power of the PV panels exceeds the rated current or power of the Epever Controller, it will be charged at the rated current or power.
What happens if I reverse the PV polarity on my Epever XTRA N?
If the PV system is connected to the Epever Controller in reverse, the controller may not be damaged and can continue to operate normally after the polarity is correctly connected.
What to do if the Epever XTRA N Controller load has no output and the load/fault icon is blinking?
If the load is not outputting 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, and wait for one night-day cycle (night time>3 hours).
Why is the load and fault icon blinking on my Epever XTRA N?
The blinking load and fault icon on your Epever Controller indicates a load short circuit. Carefully check the load connections, correct the fault, restart the controller, and wait for one night-day cycle (night time>3 hours).
What does it mean when the PV/BATT(orange)/Battery capacity level indicator is fast flashing on my Epever XTRA N?
A fast flashing PV/BATT(orange)/Battery capacity level indicator on your Epever Controller signifies that the controller is overheating. The controller will automatically cut off input and output circuits when the heat sink temperature exceeds 85°C. It will resume working when the temperature drops below 75°C.
