Tesla does something similar but somewhere in between one inverter and one inverter per panel. They have multiple inverters, usually installed per “plane” of panels. So, for example, if you have a set of panels on a south facing roof surface, those all go to one inverter. And if you have another set of panels on a west facing roof surface, those would go to a second inverter. And so on.
But there’s another difference I just discovered between Tesla and Enphase. Tesla will give me a price estimate on their website, Enphase will not, they ask all the questions, and allow all the configuration steps, but then at the end refuse to display an estimate until you give them your contact information. I clicked the little ‘x’ and closed the tab instead.
