those panels are 5a 20v each, if you wire them in series, you will get 5a 80v and the pwm will give you 5a 12v(60w), if you wire them in parallel, you will get 20a 20v, which is over the fuse rating(15a) of the panels. This is not a good solution for solar. Best case, you wire 3 panels in series and get 15a of 20v, the pwn gives you 15a 12v(180w), which is still far short of the 400w the panels produce.

The panel fuse rating is per panel and in a parallel setup, the total current splits evenly across each panel. In other words, each panel produces 5 amps and those four 5-amp streams combined create 20 amps total to feed the charge controller, but each individual panel fuse still only sees 5 amps.

This is just part of what you'd need for a complete solar setup. To utilize this stuff, you'll need batteries to store the electricity. Good high capacity ones can be pretty pricey. Generally, batteries will be the most expensive thing in your setup. Then you need way to convert your stored battery power to something more usable, like 110v AC. That's where an inverter comes in. Or you can simplify everything by pairing these panels with a portable power station AKA solar generator. You wouldn't even need the charge controller in this kit because they are built in to solar generators. These panels would wire directly to the power station. Using an all-in-one solar gen is by far the simplest way to go. Also the prices of solar gens have become pretty reasonable considering everything they do. Lastly, unlike a typical pieced together solar setup, (unless you buy a stand alone battery charger and 48v fast chargers aren't cheap) if there's no sun available you can just plug it into a standard AC wall outlet for a quick charge, because they normally have a pretty fast built-in AC charger. For example, my 2 large-ish capacity power stations use a regular PC power cord to charge from an AC outlet and my Pecron 3kWh station charges at 1800w and my Oupes 2.2kwh station charges at 1400w. Pretty darn fast.

How is a solar generator different than buying batteries and an inverter, other than having all the components in one box? Perhaps an inverter can feed into a home power line, whereas the solar generator can't?

Right. If you're going to feed into your home AC, then using a portable solar gen is probably not the way to go. Portable units main attractiveness is their portability factor, which becomes meaningless in a fixed setup. You'd probably want to build out a solar power system with individual components. I've never actually tied into a home electrical home line with either, so I don't have the experience to speak on it. But from what I understand, it's possible to do with a portable solar gen, but it's not straightforward and requires clunky workarounds.
