What you will see

  • Red light on the inverter
  • Blue light flashing for a long time in daylight
  • Screen off

Why it happens

The light is the quickest status check. On models with a small screen, touching the indicator shows today's energy, current power or the error codes. The screen goes dark after a few minutes without touch; that is not a fault.
