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 battery voltage is lower than 8V on my Epever XTRA3210N?
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 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.
What to do if the load and fault icon blink on my Epever XTRA3210N 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).
Why is my Epever Controller not working when the battery voltage is lower than 9V?
To activate the Epever Controller, ensure the battery voltage is at least 9V.
Why does my Epever Controller display a system voltage error?
If the Epever Controller shows a system voltage error, ensure that the battery voltage matches the controller's working voltage. You may need to switch to a suitable battery or reset the working voltage.
What happens if the battery connected to my Epever Controller is overheating?
If the battery overheats, the Epever Controller will automatically shut down the system. Once the temperature decreases to below 55 ºC, the controller will resume normal operation.
What happens if my Epever XTRA3210N 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 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).
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).
