Solis alarm 1034: Leakage current protection
Solis alarm code 1034 usually means the inverter has detected leakage current above its permitted protection threshold. Leakage current can occur when current escapes from the expected electrical path, often through insulation breakdown, moisture or wiring faults.
Alarm code 1034 may appear as:
- ILeak-PRO 01
- ILeak-PRO 02
- ILeak-PRO 03
- ILeak-PRO 04
When this happens, the inverter may stop producing power or disconnect as a safety response.
This type of fault may be linked to damaged PV wire insulation, ageing solar modules, incorrect wiring, moisture ingress, poor cable quality, RSD wiring issues, downstream electrical faults or another issue affecting the DC or AC side of the solar system.
Let e-Solar check your inverter and leakage current
If the alarm appears only during rain, early morning or high humidity, the issue may be moisture-related. However, it should still be checked if it keeps returning.
This could be caused by:
A. Damaged PV wire insulation.
B. PV wire is incorrect gauge.
C. Faulty transformer downstream.
D. Incorrect wiring of RSD.
E. Buried AC wires are saturated with wire
F. AC wire is low quality
If Solis alarm 1034 keeps appearing, it is worth having the system inspected. Our Perth-based solar team can test the system safely and help determine whether the issue is linked to a single PV string, damaged insulation, moisture ingress, wiring quality, RSD wiring, inverter firmware or another system fault.
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 attempt to isolate strings, test leakage current or inspect DC wiring yourself. These checks require qualified electrical testing and safe handling of high-voltage solar circuits.
