Why is my Epever Controller not working even though the wiring is correct?
If the wire connection is correct, but the Epever Controller is not working, the battery voltage may be lower than 8V. Please check the battery's voltage and ensure it is at least 8V to activate the controller.
What to do if Epever Controller is used in area with lightning strikes?
If you plan to use the Epever Controller in an area prone to frequent lightning strikes, it's advisable to install an external surge arrester.
How to fix a charging LED that is OFF on my Epever Tracer8420AN during the day?
If the charging LED is off during the daytime when sunshine falls on PV array properly, it may be due to a PV array open-circuit. Confirm whether the connection of the PV array is correct and tight.
How to prevent battery reverse polarity on Epever Tracer8420AN?
Do not connect the battery wires with reverse polarity, as this may damage the Epever Controller.
