What to do if the Epever TRIRON3210N is not working even when the wire connection is correct?
If your Epever Controller isn't working despite correct wire connections, the battery voltage may be too low. Ensure the battery voltage is at least 9V to activate the controller.
Why is the charging LED indicator off on my Epever TRIRON3210N Controller during the day with proper sunshine on the PV modules?
The charging LED indicator might be off because of a PV array disconnection. Confirm that the PV and battery wire connections are correct and tight.
