GoodWe error 08: AC HCT failure
GoodWe alarm 08 usually means there is a problem with the AC output current sensor, the control board, or that an intermittent fault has occurred due to external interference such as magnetic fields.
This fault may temporarily prevent the inverter from exporting power safely and can indicate that the AC monitoring circuitry is not functioning as expected.
Contact e-Solar for AC current sensor inspection
Do not attempt to open the inverter or tamper with internal components. Restarting the inverter may clear an intermittent fault. If the error persists, our Perth-based technicians can check the AC current sensor, control board and firmware settings, and determine whether a repair or firmware update is required.
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
Our team will guide you safely through diagnosing the AC HCT failure and recommend the correct steps to restore safe inverter operation.
