What to do if the 8H, 4H, 2H, and 1H red LED indicators are flashing together on my Epsolar Controller?

  This indicates an overload or short circuit. For an overload, reduce the load and press the button once; the controller will resume working after 3 seconds. For a short circuit, the controller will automatically resume working after 10 seconds after the first occurrence. If a second short circuit occurs, press the button; the controller will resume working after 3 seconds.

Why is the green charging LED indicator fast flashing on my Epsolar LS0512R Controller?

  A fast flashing green charging LED indicates that 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.

  Slowly flashing red battery LED indicators indicate battery under voltage. The load output is normal, and the charging LED indicator will return to red automatically when fully charged.

How to fix the charging LED indicator when it's off during the daytime with sunshine on the PV modules of my Epsolar Controller?

  Christopher ChavezAug 23, 2025
  The charging LED indicator being off during the day when the PV modules are receiving sunlight means there may be a PV array disconnection. Check that the PV and battery wire connections are correct and tight.
