I made a simulation of the same building with exactly the same PV-system but for different locations. But in the one case the standby consumption of th einverter is 24 kWh/a and in the second case 26 kWh/a. What could be the reason for this difference? I checked all the input data douple and they are similar in both cases.

Hello Renan,

the total stand-by consumption also depends on the irradiation/ climate data of the selected location. This means that a site has reached more phases in which the inverter has not reached its minimum feed-in energy from the pV system, so the inverter switches to stand-by mode.

Hi,

I have a question regarding how module degradation might affect standby consumption.

I've noticed a discrepancy in the first-year generation figures: the simulation results show 792,161.3 kWh, while the report states 792,333 kWh. Please see attached screenshots.

Could this difference be attributed to standby consumption being 72 kWh instead of the 86 kWh mentioned in the report?

Thank you.

Kind regards,

Hi Felix,

could you send me the project file, please? You can send it here in the forum as private message to me, so I can have a look, thank you.

Kind regards,

Martin

I replied via DM, attaching a similar model that has the same issue. 

Thanks.

where did you send it? I did not receive a message from you.

Kind regards, Martin
