PVWatts v5 AC nameplate rating

I have been checking the PVWatts Version 5 Manual, and have one question related with Inverter model (section 12):

How does one define the AC nameplate rating (Pac0)?
Is AC nameplate rating equal to DC rating of the system divided by DC-to-AC ratio (1.1):

Pac0 = Pdc0/1.1

Where:

Pdc0 = System size (4kW by default)

Meaning:

Pac0 = 4/1.1 = 3.63 kW

?

Thank you for the reply.

Yes. For the PVWatts model, the total inverter nameplate AC capacity is determined by the system nameplate DC capacity and DC-to-AC ratio as you describe.

For the detailed photovoltaic model, the total inverter nameplate AC capacity is the product of a single inverter's AC capacity and the number of inverters.

Best regards,
Paul.

As always from you: quick and informative reply.
Thank you Paul.
