What to do if the Epever Controller battery level shows full, the battery frame blinks, and the fault icon blinks?
If the battery level shows full, the battery frame blinks, and the fault icon blinks on your Epever Controller, it indicates a battery over voltage issue. Check if the battery voltage is higher than the OVD (over voltage disconnect voltage), and disconnect the PV.
What to do if the Epever SolarV 4210AN Controller load is not outputting and the load and fault icons blink?
If the load has no output and the load and fault icons blink on the Epever Controller, it means the load is overloaded. Reduce the number of connected electric equipments. You can also try restarting the controller or waiting for one night-day cycle (night time>3 hours).
What to do if the Epever Controller battery level shows empty, the battery frame blinks, and the fault icon blinks?
If the battery level is empty, the battery frame blinks, and the fault icon blinks on your Epever Controller, it signifies that the battery is over discharged. When the battery voltage is restored to or above LVR (low voltage reconnect voltage), the load will recover.
Why is the Epever Controller not working even though the wire connection is correct?
If the Epever Controller is not working despite correct wiring, the battery voltage may be too low. Check the battery voltage; it needs to be at least 8V to activate the controller.
What to do if the Epever SolarV 4210AN Controller battery level shows empty, battery frame blinks, and fault icon blinks?
If the battery level shows empty, the battery frame blinks and the fault icon blinks on the Epever Controller, it indicates battery overheating. The controller will automatically turn the system off. It will resume operation once the temperature declines below 55 ºC.
How to troubleshoot LCD display issues on the Epever Controller during daytime when sunshine falls on PV modules properly?
If you are experiencing LCD display issues on your Epever Controller during the daytime with proper sunshine on the PV modules, it might be due to PV array disconnection. Confirm that all PV wire connections are correct and tight.
