help needed for three inverter modeling in a single pv plant

[Atik-Uz-Zaman Atik]

hi dear, if i want to use three inverters each 50kw for a total 150kw solar plant, what will be the changed in the PVSystem code below? can anyone help? 

import pvlib
from pvlib.location import Location
from pvlib.pvsystem import PVSystem
from pvlib.modelchain import ModelChain
from pvlib.temperature import TEMPERATURE_MODEL_PARAMETERS

import matplotlib.pyplot as plt
import pandas as pd

location = Location(
    latitude=24.772046553556823,
    longitude= 89.84327976048408,
    tz="Asia/Dhaka",
    altitude=0,
    name="Dhaka"
)



CEC_modules=pvlib.pvsystem.retrieve_sam ('CECMod')
CEC_inverters=pvlib.pvsystem.retrieve_sam ('CECInverter')

module = CEC_modules['Canadian_Solar_Inc__CS1U_420MS']
inverter = CEC_inverters['SMA_America__STP_50_US_41__480V_']

temperature_parameters = TEMPERATURE_MODEL_PARAMETERS['sapm']['open_rack_glass_glass']

system = PVSystem(
    surface_tilt=20,
    surface_azimuth=180,
           module_parameters=module, inverter_parameters=inverter,
           temperature_model_parameters=temperature_parameters,
           modules_per_string=17,
           strings_per_inverter=21
           )

modelchain = ModelChain(
    system,
    location,
    aoi_model='physical',
   
    )

times = pd.date_range(start="2021-07-01",end="2021-07-07",
                      freq="5min",tz=location.tz)

clear_sky = location.get_clearsky(times)

clear_sky.plot(figsize=(16,9))
plt.show()

modelchain.run_model(clear_sky)
modelchain.results.ac.plot(figsize=(16,9))
plt.show()

pvlib (currently) limits a PVsystem to a single inverter. To model a system with 3 inverters, set up two additional PVSystem & ModelChain instances, then add the AC power from the ModelChainResult.

Best,
