Solis alarm 1059: Grid voltage sampling value deviated
Solis alarm code 1059 usually means the inverter has detected a difference between the grid voltage it is reading and the actual AC voltage at the system.
Alarm code 1059 may appear as:
- Vg-Sample
When this happens, the inverter may stop exporting power, reduce operation or disconnect from the grid as a protective response.
This type of fault may be linked to voltage sampling behaviour, AC wiring, grid voltage changes, inverter measurement issues, internal sensing faults or another issue affecting how the inverter reads grid voltage.
Let e-Solar check your inverter and voltage readings
If the alarm appears once and clears after a restart, the inverter may have recovered from a temporary sampling issue.
If Solis alarm 1059 keeps returning, it is worth having the system checked. Our Perth-based solar team can inspect the inverter, test AC voltage and help determine whether the issue is linked to voltage sampling, AC cabling, inverter settings, internal sensors or wider grid 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, switchboard or AC wiring yourself. If the issue is persistent, a qualified technician may need to compare inverter voltage readings against measured AC voltage and assess whether the inverter is operating correctly.
