iStore error 2072: Transient AC overvoltage
iStore alarm 2072 usually means the inverter has detected that the AC phase voltage has exceeded the transient overvoltage protection threshold. When this happens, the inverter may temporarily disconnect from the grid to prevent damage to internal components and ensure system safety.
This can occur due to local grid fluctuations, sudden voltage spikes, or nearby high-demand events. Occasional alarms may be linked to short-term network anomalies, while frequent alarms could indicate persistent voltage issues.
Contact e-Solar before resetting the system
Power off the inverter before inspection (turn off the AC output and DC input switches) and follow the safety label instructions. After powering on, e-Solar technicians can verify the grid connection, check peak AC voltages, and adjust the overvoltage protection thresholds if needed, with approval from the local power operator.
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
This helps ensure the inverter and grid connection are operating safely and prevents damage from transient overvoltage events.
