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

What does 307 mean?

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.

• 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

Click steps to track your progress.

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.
