Inverter Clipping (overload loss) for On-grid

[Ziad]

Hello, There is something I can't fully understand , Shouldn't there be a limit for energy generation (Euseful) as Pnom ratio (DC/AC) is increased then Euseful should decrease again because of the overload losses? because I noticed that generation keeps increasing as i continue to add more strings for the same inverter till reached the max number of strings allowed. Thanks.

Dear Ziad,

Without the project, I can’t know what the issue is. Could you please send us your project at support@pvsyst.com and explain what the issue is?

There is a limit for maximum output power on the inverter, but since you are adding more strings to the inverter, it means that the inverter will hold onto maximum power generation for longer amounts of time. Essentially you are increasing the time for maximum operation resulting in overall more solar generation.
