iStore error 2039: Output overcurrent
iStore alarm 2039 usually means the inverter has detected transient output current above the permitted threshold. This can happen if the grid voltage drops sharply or if there is a short circuit affecting the grid or AC output side.
When this happens, the inverter may trigger protection and stop operating until the fault clears.
An occasional alarm may be linked to a temporary external condition. If the alarm occurs frequently or affects energy yield, it may point to AC-side faults, output short-circuit conditions, grid voltage disturbances or another system issue.
Let e-Solar check your inverter output and AC connection
If iStore alarm 2039 appears once and clears by itself, the inverter may have responded to a short-lived grid or output condition.
If the alarm keeps returning, contact e-Solar. Our Perth-based solar team can inspect the inverter, review AC-side behaviour and help determine whether the issue is linked to output overcurrent, grid voltage drops, AC wiring, short-circuit conditions or inverter protection settings.
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 fault persists, a qualified technician may need to test the output circuit, inspect AC cabling and confirm whether the system is safe to operate.
If you’re unsure, don’t risk it. Contact e-Solar for safe, local support.
