AC Cable Sizing Alert — Ensure correct cable capacity

What does AC Cable Sizing mean?

The AC cabling for the inverter must be correctly sized to handle the maximum fault current output and operational current. Incorrect sizing can lead to system issues or failures.

• Cables are too small for the inverter's current output.
• Installation conditions differ from manual specifications.
• De-rating factors not considered in cable selection.
