What does it mean when the PV/BATT(orange)/Battery capacity level indicator is fast flashing on my Epever Controller?
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.
How to fix the charging LED indicator off during daytime when sunshine falls on PV modules properly on my Epever XTRA3210N 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 my Epever XTRA3210N 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 XTRA3210N 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).
Why is the charging indicator on my Epever Controller flashing green rapidly?
A rapidly flashing green charging indicator on your Epever Controller indicates a battery over voltage. Check if the battery voltage is higher than the over voltage disconnect voltage (OVD) and disconnect the PV.
Why is my Epever XTRA3210N 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 (lower than 8V). Check the battery voltage and ensure it is at least 8V to activate the controller.
What happens if my Epever XTRA3210N 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 XTRA3210N'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 XTRA3210N 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 XTRA3210N 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.
