DC low DC input voltage too low for feeding energy into the grid

Fronius · Symo Advanced Manual

Hva betyr 307 ?

The DC input voltage from the solar modules is below the minimum threshold required for the inverter to operate and feed energy into the grid. This results in a short-term interruption, but the inverter will resume its start-up routine when conditions improve. This status code is routinely displayed during periods of low insolation (e.g., morning and evening) and does not indicate a fault at those times.

Vanlige årsaker

  • Insufficient solar insolation on the PV array (e.g., dawn, dusk, heavy cloud cover, shading)
  • Problem with the DC wiring or connections to the PV array leading to voltage drop

Reparasjonssteg & Sjekkliste

Klikk på steg for å spore fremgangen.

  1. 1

    Wait for a sufficient level of insolation (sunlight) on the solar modules.

  2. 2

    Check that solar modules are not covered by snow, shade, or other obstructions.

  3. 3

    If this status code keeps recurring outside of normal low light periods, contact your system engineer.
