No it doesn't.
Any Enphase micro inverter goes to full power from the factory, there is no fine-tuning needed from an Envoy.
The IQ8+ has these input specs:
MPPT voltage range 29 - 45 Volt
Max DC current [module Isc] 15 amps
With the side node: Maximum continuous input DC current is 10.6A
The op's PV panel has these specs:
The are 54 cells (x cut in half = 108 cells) panels. Normal is a 60 cell/120 half cell panel with a higher voltage.
Vmp: 30.84 Volt (within MPPT in range but at the lower end of 29-45 volt of the IQ8+)
Imp 12.51 amp
Since the IQ8+ can not input more than 10.6A there is an issue:
Panel: 30.84V x 12.51A = 385 watt
The IQ8+: 30.84V x 10.6A = 326 watts == 85% of what panel is capable of.
This is just a miss-match between panel & micro inverter choice imo.
Who ever made the decision to couple these 2 just looked at watts and not at the specifics of Volts & Amps.
The Enphase calculator says that they _are_ compatible:
