Growatt SPH 3600TL BL-UP
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.
