What to do if Epever Controller load terminals have no output?
If the load terminals of your Epever Controller have no output, it may be due to an overload or a short circuit. Try removing or reducing the load. Then, press the button on the controller. The controller should resume working after 3 seconds.
Why is my Epever Tracer 4215BN flashing all LED indicators, with the battery indicator flashing red?
If all the LED indicators on your Epever Controller are flashing, with the battery indicator flashing red, this indicates a system voltage error. Check whether the battery voltage matches the controller's working voltage. You may need to change to a suitable battery or reset the working voltage. Remove all faults and click the button to resume working.
What to do if the battery LED flashes green fast on my Epever Tracer 4215BN?
If the battery LED on your Epever Controller flashes green fast, it means the battery voltage is higher than the over voltage disconnect voltage (OVD). Check if the battery voltage is too high and disconnect the solar module.
What does it mean when the battery LED flashes red on my Epever Tracer 4215BN?
If the battery LED on your Epever Controller flashes red, it indicates a battery low voltage disconnect. The controller will automatically cut off the output. The LED indicator will return to green when fully charged.
What does it mean if the battery LED flashes orange on my Epever Tracer 4215BN?
If the battery LED on your Epever Controller flashes orange, it indicates battery under-voltage. The load output is normal, and the charging LED indicator will return to green automatically when fully charged.
How to fix the charging LED being off on my Epever Tracer 4215BN during the day?
If the charging LED is off on your Epever Controller during the daytime when sunshine properly falls on the PV, it could be due to PV array disconnection. Confirm that the PV and battery wire connections are correct and tight.
Why are all the indicators off on my Epever Controller even though the wire connections are correct?
If all the indicators are off on your Epever Controller, even though the wire connections are correct, it could be due to one of two reasons: 1. The battery voltage is lower than 9V. Please check the battery voltage. It needs to be at least 9V to activate the controller. 2. The PV voltage is less than the battery voltage. Check the PV input voltage, which should be higher than the battery.
