Using flex panels, but get minimum operating value error

[Tormi Teedemaa]

Hello,

I have a problem designing PV array with flex panels. I've tried almost everything, changing the inverter to a smaller one, bigger one, changing the number of strings, modules in series. I dont see what i am missing here.

Dear Tormi Teedemaa,

This is a PV module that you have defined yourself or imported from manufacturer. It is possible that some parameters are not well defined. Moreover, the choice of inverter should be based not only on the power but also for instance the operating voltage. In your print shot you you have only 1 module in series and 666 strings that is resulting in operating condition for your system of 31 V at Vmpp (60°C) when the inverter you have chosen has an operating voltage between 180-1000V, thus the error message in your print screen. 

By clicking the Sizing button, you can more clearly see the different limitations in your system.

Kind regards
