Can you explain your application a little bit more? What is this going to power? A room like a shed? A vehicle? What kind of storage do you plan on? Lead acid or lithium?
I ask this because of the trend of calling every installation a solar generator. If you have panels, a charge controller, a battery, a 12V fuse block (if you go that route), that really works out to a full blown solar power system. When I hear that term solar generator my brain goes to those self contained cases no bigger than a battery that you can unplug from the PV source and carry elsewhere to use the stored power, like my Goal Zero, and the Bluetti and the Jackery boxes. I mean, in my case, I charge my Goal Zero from the wall, so it's little more than a portable battery with fixed 12v, 110v and USB output options. So I am just a little confused by the use of the term solar generator that I see here. I also see them called portable power stations, which seems more accurate, since these don't "generate" anything. The provide power generated and stored in them.
As you are in the learning stages, you are doing it exactly right. Keep the budget down as you learn by building the Yugo and THEN build the BMW when you have a good working knowledge!
If not for Will's book and youtube channel, I would not know anything about solar. You are in the right place to learn.
