  If the Epsolar Controller battery indicator is flashing red, it indicates an overload or short circuit. In case of overload, reduce the load and press the button once; the controller will resume working after 3 seconds. For a short circuit: after the first occurrence, the controller will resume automatically after 10 seconds. If it happens a second time, press the button, and the controller will resume after 3 seconds.

Why is the green charging LED indicator flashing on my Epsolar Tracer-2210RN Controller?
- D

  The green charging LED indicator flashes on the Epsolar Controller because 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.

  If the Epsolar Controller battery LED indicator shows a solid red color, it indicates that the battery is over discharged. The controller has automatically cut off the output. The LED indicator will return to green automatically when the battery is fully charged.

How to fix Epsolar Tracer-2210RN Controller when charging LED is off during the day?
- K
  Kristen MartinezAug 29, 2025
  If the charging LED indicator is off during the daytime, even when sunlight is properly hitting the PV modules, it could be due to PV array disconnection. Check that the PV and battery wire connections are correctly connected and tight.
