Back to the OP, and in out of the rain, I see the advent of AIO's to be a major shift in the world of solar. Not too long ago you had to make everything via component and there weren't that many options out there and it was very much a Rich Man's Game. Then the AIO's came out and people could rig up an autotransformer and make the systems work.
Back not too long ago it was an unfortunate thing that people would post threads trying to make small systems and there was a very heavy bias towards the high end equipment. I don't know how many threads I read where people would be trying to build a small cabin system or workshop system, had a budget of $1000 or so, and right out the gate would only get recommendations about "Ya gotta spend $800 on this Victron thingy, and another $600 on that Victron Doodad" and so on completely blowing a budget out of the water and there was very much an air of "What? You're too poor for Victron? You can't do it? Well, sucks to be you."
It was kinda disheartening to read those threads and see again and again the paywall involved in getting into solar. Once everyone and their uncle started making AIO's and MPPT controller clones, that paywall got a little shorter, but I think what really turned things around was the early grid tie systems getting upgraded and panels coming down to the 2nd hand market.
Now granted, I may be just high on pollen and rain, but I remember when the
Harbor Freight Fisher Price My First Solar kit was a good deal, poly panels could be found on sale for $2/watt, and golf cart and
WallyWorld batteries were THE option unless you wanted to try to build your own batteries and had a 1 in 3 chance of your cells not showing up from AliBabaXpress Store 8675309 for a LOT of money.
Things change quickly. Look through some of Will's old videos when he was still in the RV and compare the parts he specced at the time to what's available for the same money now. Big changes!
Like I said, there is a significant paywall still. Grid tied systems are still something that is onobtanium for a lot of people. The market is getting better, but who knows what clusterf#$k will happen after each election around the world.
If you head to the foothills out in Monroe it starts in August and ends in July. ?
