The Problem

GoodWe error 09 17 29: Utility loss

GoodWe alarm 09 17 29 usually means the inverter has detected a loss of utility power or an AC disconnection. This can occur if the grid is down, AC cables are disconnected, breakers have tripped, or the grid connection is improper.

When this happens, the inverter may stop exporting energy and pause backup or grid-tied operation. An occasional alarm may be due to a temporary grid fault, while repeated occurrences suggest AC-side connection or grid issues that need professional assessment.

The Solution

Contact e-Solar to inspect the AC connection

If GoodWe alarm 09 17 29 appears, do not attempt to reconnect or reset the inverter without assessment. Our Perth-based solar team can check grid voltage, inspect AC cabling and breakers, and confirm proper connection to restore safe operation.

Contact e-Solar and let us know:

  • The exact error code on the screen or app
  • When the code appears
  • Whether your solar production has dropped
  • Your inverter model, if you know it

Power off the inverter before inspection (turn off the AC output and DC input switches) and follow the safety label instructions. After powering on, e-Solar can verify the AC connection, inspect breakers and cables, and confirm the inverter is correctly connected to the utility grid.
