My EC155 control panel keeps beeping and the LED flashes

On the new version of the control panel (with BLUE LED’s) if you experiencing beeping and flashing of the top green LED on the Level display this would indicate that the system is detecting an overvoltage of more than 15V.



On older versions of the control panel (with GREEN LED’s). If the system is detecting an overvoltage of more than 15V the system will shut down but you will not get any beeping from the control panel.

Overvoltage can come from 3 different sources.

  1. 230V mains chargers
  2. Solar
  3. Split charging while driving (smart alternators and regen braking)
