Why "EArray" is null under a certain threshold of "GlobHor"

[RomActivS]

Hello

I made different simulations changing parameters like modules or inverters, and I always have the "Erray" equal to 0 under a certain threshold of "GlobHor". As you can see on the file attached.

I would like to understand why the extracted data "EArray" is 0 under a certain threshold of "GlobHor"?

Thanks in advance for your help.

There may be several situations:

- PVsyst doesn't treat hours with GlobInc < 10 W/m2 (remember that a very covered weather corresponds to 40-50 W/m2).

- The inverter may be under its operating conditions. Please have a look on the inverter losses (IL_PMin, IL_VMin) for these particular hours.

You'll find attached a file with the results of a simulation showing the inverter losses, but it doesen't seem to be these values that make the EArray equal to 0.

It seems that we have EArray = 0 when GlobHor = DiffHor.

Can you explain me why I have that?

I can not attached a file...
