Huawei optimizer - error

[pongsakornnorcum]

after update pvsyst version 8.0.4 Why does the problem still occur?

 

[Robin Vincent]

This issue is due to a bug in the automatic string attribution to each MPPT (triggered when changing something in your system or when clicking on reinitialize inverter list).

It should be solved in the 8.0.5.

Meanwhile, to be able to simulate your system you can try deleting and adding back each inverter one by one until the error message disappear.

Make sure your system is fully defined before doing so, as any modification on the subarrays definition will trigger a new string attribution,which could lead to the issue reappearance.
