Event 3302 — Unstable operation

What does Event 3302 mean?

The inverter is experiencing unstable operation and cannot connect to the utility grid. This is typically due to insufficient power being supplied at the DC input of the inverter.

• PV modules are not dimensioned correctly for the inverter's requirements.
• PV modules are covered by snow, debris, or are otherwise shaded.
• PV modules have defects or are damaged, reducing their power output.
• The connected battery has a fault or is not functioning correctly, impacting DC power supply.

Click steps to track your progress.

1. 1

   Inspect your PV modules to ensure they are clean and free from any shading, such as snow, leaves, or other debris.

2. 2

   Check the design and sizing of your PV module array to confirm it meets the inverter's operational specifications.

3. 3

   Visually inspect all PV modules for any signs of physical defects or damage.

4. 4

   If a battery is connected to the system, verify its current status and ensure it is operating correctly.

5. 5

   If the problem persists, consult your system documentation or a qualified installer to review the PV system's dimensioning and health.
