AC voltage too low

Hva betyr 103 ?

This code indicates that the AC voltage supplied by the public grid is too low, preventing the inverter from feeding energy into the grid. The inverter disconnects but will attempt to reconnect once grid conditions improve.

• AC grid voltage drops below the permissible lower limit for the inverter's operation.
• Voltage sags on the public grid due to high loads or faults.
• Potential issues with the grid connection integrity or undersized AC cabling.

1. 1

   Inspect the AC grid connections for any loose or damaged wiring.

2. 2

   Measure the AC voltage on the inverter connection sockets to verify it meets the required 220/230 V (+10% / -5%) or 380/400 V (+10% / -5%) range.

3. 3

   If this status code keeps recurring, contact your system fitter or grid operator to investigate grid quality.
