iStore error 2081: 3rd party optimisers fault
iStore alarm 2081 usually indicates that a compatible third-party optimiser connected to your PV string has reported a fault. This can affect the power output of the affected string and may trigger protective measures in the inverter.
The alarm may be caused by faulty optimisers, communication errors, or configuration issues. It is not a normal operating message and should be investigated promptly to prevent energy loss or damage.
Contact e-Solar to inspect optimiser and string performance
Power off the inverter before inspection (turn off the AC output and DC input switches) and follow all safety label instructions. After powering on, e-Solar can verify the optimiser status, check the communication and connection integrity, and confirm the PV string is operating correctly.
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 that any faulty optimiser or string issue is identified safely and efficiently.
