Put your 5 panel in series.
They are 50 Voc panels and the Growatt is rated for 450 V max.
So 5 in series, in very cold weather will be under 300 V, so no issues there.
Meanwhile operating voltage of those panels at max output is ~42 V, which with 5 panels in series = ~210 V, while the inverter has MPPT input voltage range of 120-430 V.
If you wanted in a cold climate you could add another 2 panels of the same panels in series, or 3 panels if you are not in a cold climate.
