  If the load status indicator on your Epsolar Controller is red and flashing, 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. In case of a short circuit, the controller will automatically resume working after 10 seconds on the first occurrence. If a second short circuit happens, press the button, and the controller will resume working after 3 seconds.

Why are the battery LED indicators red and loads not working on my Epsolar Controller?
- K
  Kari LewisAug 11, 2025
  If the battery LED indicators on your Epsolar Controller are red and the loads are not working, it means the battery is over discharged. The controller automatically cuts off the output. The LED indicator will return to green automatically when the battery is fully charged.

Why is the green charging LED indicator fast flashing on my Epsolar LS1024?

  Shelly SmallAug 18, 2025
  If the green charging LED indicator on your Epsolar Controller is flashing rapidly, 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.

  If the battery LED indicators are orange on your Epsolar Controller, it signifies battery under voltage. If the load output is normal, the charging LED indicator will return to green automatically when fully charged.
