Enphase IQ8MC Microinverter
Different in kind from everything else in this category. Each IQ8MC sits behind one panel and puts out a maximum of 330W of AC on its own, so the catalogue's 0.33kW is a per-unit figure, and a real installation is a string of them. That buys per-module MPPT (shading on one panel does not drag the rest down), low-voltage DC on the roof, and rapid shutdown. The datasheet's 1.43A maximum output current means G98 headroom is a question of how many units you fit, not of one unit: Enphase's own limit is 11 units on a 16A single-phase circuit. Maximum efficiency is 97.5%, warranty up to 25 years provided an internet-connected IQ Gateway is installed.

The reason to pick this over the 4kW SPH models is the paperwork: its datasheet rated output current is 16A, so it fits a G98 notification instead of a G99 application. You give up a few hundred watts of AC output to get there, and the 7,500W maximum recommended PV input still leaves room to oversize the array. Two MPP trackers, 97.2% maximum efficiency and a 5-year standard warranty (10 optional) are the same story as the rest of the range.
