Min number of panels in a string/real voltage required) for Growatt SPH3600YL BL-UP

[Guy from Glasgow]

The growatt SPH3600TL BL-UP invertor has minimum volatage of 120V and start Voltage range from 120 V
I have 4 DMEGC DM410M10-54HBB Full Black Solar PV Panel 410W
panels which have following working voltages (right 2 columns) -
max power voltage 29.72V (NOCT - 800 w/m2).

Question:
would these 4 panels work on this MPTT (working range 120+450V, min start voltage 120V)?
Or do I need at least 5 on each string?

I think you need at least five.
You need to be comfortably in the range for the mppt to reliably operate.
