PVLIB - How to properly define system size with couple inverters

Question

I'm trying to model a system with 5 inverters but there is no parameter for PVSystem object that takes number of inverters, only modules per string and strings per inverter (but still it assumes that there is only one inverter). Also there is no argument for power installed which would allow to skip sizing details.

For large PV plants it is crucial as for example there would be ~50 000 PV modules and they can't just be connected to only one inverter.

How could I properly set it up so I can do further calculations?

As of 2020-06-21, you can only simulate a system with multiple inverters "manually". That means, you need to calculate the topology yourself:

• Number of required inverters
• Strings per inverter (and modules per string)

Then you can simulate each inverter separately.

Hopefully, this will change in the future. :-D
