Post subject:  Isc vs Imax input of Inverter

Hi experts,

Why PVsyst compares between the array Isc and the inverter maximum PV current input not the maximum Isc of the inverter.

For example: an inverter has 14 inputs, Isc max input of 140A while Imax PV input is 120A so, safely it can take on 14 strings (Isc of the panel is 8.98A @ STC) but it shows the error as in picture attached.

Since I'm considering Isc of the array, it should take Isc input of the inverter into account.

Any explanations ?!

Sincerely,
Eng.Mohammad AlKour

This can be overridden in the OND file. Under Contractual specifications, uncheck the box next to "Maximum PV Current". This has no impact on the simulation results.
