iStore error 2070: Active islanding
iStore alarm 2070 usually means the inverter has detected islanding during an AC power outage or an abnormal grid condition. When this happens, the inverter stops feeding power into the grid to prevent unsafe conditions and protect both the inverter and the wider electricity network.
This is typically a safety measure and does not always indicate an internal inverter fault. It may be triggered by grid interruptions, network instability, or temporary loss of AC supply.
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 can verify the grid connection voltage, inspect inverter operation, and confirm that the system reconnects safely once normal grid conditions return.
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 ensures the inverter and grid connection are operating safely and prevents potential risks associated with islanding.
