iStore error 2040: Output DC component overhigh
iStore alarm 2040 usually indicates that the DC component of the inverter’s output current has exceeded the permitted threshold. This can happen due to abnormal operating conditions, grid instability, or temporary faults in the DC side of the solar system.
When this occurs, the inverter may trigger protective measures to prevent damage and stop exporting power until conditions return to normal.
An occasional alarm may resolve automatically once the external conditions stabilise. Frequent alarms may indicate a persistent DC issue, and the inverter should be checked by a professional.
Contact e-Solar before resetting the system
If iStore alarm 2040 appears, do not attempt to manually reset the inverter repeatedly. Our Perth-based solar technicians can safely inspect the inverter and determine whether the DC component issue is linked to the inverter hardware, DC cabling, PV modules, or site 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
The inverter may automatically recover once external conditions return to normal. If the alarm persists or occurs frequently, e-Solar can perform detailed testing and recommend the safest next step.
