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.

SMA Sunny Boy 3.6

A conventional two-MPPT string inverter sized for a G98 notification: the datasheet gives a 16A maximum output current at a 3,680W rated power. Its 5,500Wp maximum generator power means a meaningfully oversized array is within spec. Maximum efficiency is 97.0% and the standard warranty is 5 years, with 10 and 15 as options. It weighs 17.5kg, which the datasheet calls a one-person installation.
