PV output too low for feeding energy into the grid

What does 306 mean?

This code indicates that the photovoltaic output power is insufficient for the inverter to begin or continue feeding energy into the grid. This is often displayed routinely during periods of low sunlight, such as early morning or evening, and does not necessarily indicate a fault.

• Insufficient solar irradiation (low insolation) due to time of day, weather conditions (e.g., cloud cover, snow), or shading.
• Dirty PV modules reducing efficiency.
• Faulty PV string or module producing lower than expected power.

Click steps to track your progress.

1. 1

   Wait for a sufficient level of insolation; the inverter will resume operation automatically when power increases.

2. 2

   Inspect solar modules for any covering (e.g., snow, debris) or excessive shading that might reduce PV output.

3. 3

   If this status code keeps recurring despite good insolation, contact your system engineer to check PV array performance.
