If I want to simulate FPV system in PVsyst, for the temperature coefficients Uv and Uc, how much should I insert for each value?

So I am designing a 2MW FPV system and in the design I used about 7 strings inverters and no MPPT, does this mean they are central?

I have a question regarding the use of the central inverter. I am designing a 2MW floating PV system and the system suggested string inverter, however, I would like to try the central inverter to compare between systems. Where can I find the central inverter option?

I would like to simulate 2 MW floating PV system, how to start ?
