iStore error 2064: Device fault
iStore alarm 2064 usually indicates an unrecoverable internal circuit fault. This may involve the boost input, control circuit, inverter circuit, residual current sensor, temperature detection, EEPROM, auxiliary power supply, grid relay, or DC bus.
This alarm may trigger if the inverter detects that its internal systems are not operating within safe parameters, and it will typically interrupt inverter operation to protect the system.
Contact e-Solar before resetting the system
Turn off the AC output switch and DC input switch before inspection, following the inverter’s safety label instructions. After powering back on, e-Solar can verify the inverter circuits, check the DC bus, assess temperature sensors, and confirm proper operation of all internal systems.
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
Our Perth-based technicians will safely assess whether the device fault is linked to internal inverter circuitry, DC bus conditions, or auxiliary components, and advise on corrective actions.
