Fronius error 107: No AC grid detected
Fronius error code 107 usually means the inverter cannot detect a valid AC grid connection, or the AC grid is outside the permissible operating limits. When this happens, your inverter may stop feeding energy into your home or the grid until the grid connection is safe and stable.
This is usually not an internal inverter fault. It is a safety response that prevents the inverter from exporting power when it cannot confirm a suitable grid connection.
This can happen because of a temporary grid outage, a tripped AC breaker, a grid supply issue, an inverter connection issue or voltage and frequency conditions outside the inverter’s approved range.
Let e-Solar check your inverter and grid connection
If the code appears during a power outage or grid interruption, your inverter may resume normal operation once the grid returns and passes its safety checks.
If Fronius error code 107 keeps returning, appears when the rest of your home has power, or your solar production has stopped, it is worth having the system checked. Our Perth solar experts can inspect the inverter, review the AC connection and help determine whether the issue is linked to the grid supply, switchboard, inverter settings, AC cabling or wider network conditions.
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
Do not open the inverter or attempt electrical testing yourself. If the issue is persistent, a qualified technician may need to test voltage and frequency at the switchboard, inspect the AC cabling, review inverter settings or advise whether the matter should be raised with the network provider.
