Mh, I have an academic background in electrical engineering with focus on energy storage (primary), power electronics (and grids). I must say, in terms of academic knowledge the distinction made in that explanation is nonsense. MPPT devices also use pulse width modulation as an underlying technique but have another layer of feedback control on top. I also don’t think that you can say that the power electronic circuits are generally different between the two. But of course that additional control layer probably means there’s additional microelectronic circuitry.

HOWEVER, I know marketing people and maybe the distinction presented there makes sense when talking about actual products on the market and under which product categories they’re sold…

I am too. Fun fact (you probably know if you support that message, but for everyone else): Dresden’s destruction is just so well-known because it was abused by Nazi propaganda to “show how evil those allies are”. Other German cities, and of course cities which fell victim to the Luftwaffe, saw much worse destruction.

I’m not that experienced with http(s) hosting, but for the two sites I host, I used Certbot with nginx. It seems the combination of the two does the same thing as caddy which was suggested a few times.

So you could either install certbot and point it to your working nginx http config (then certbot will try to get the ssl certificates and modify the nginx config so it works for https and https connections are preferred) or ditch nginx for caddy.
