Apple et all stopped including charger, cable, headphones etc because it's tremendous amount of ewaste. I already have cables, charges, headphones. I don't need crappy earbuds, if i need them i will buy them. I think the EU explicitly banned pack in power adapter and cables like ~10 years ago? There's already probably 25 USB adapters on the planet for every man woman and child

The advantage of sodium battery means anybody can produce it, there's no geopolitical alliances needed to manufacture them. Lithium is super rare by comparison. Any and every country can domestically produce sodium batteries forever. The low temp operating envelope of sodium is interesting, but only 11% of the worlds population lives somewhere that is useful. The big benefit is any country can stick a straw in the ocean and build a battery factory regardless of sanctions. Go look at Iran right now if you want to understand why I keep harping on this point.

I dunno, people on boats and in vans buy this stuff and run it for a decade or more without problems. Name brands like anker and ecoflow have very solid track records and 5-8 year warranty on most of this stuff. It's not fly by night Chinese crap. All this stuff has a very solid track record at this point. I bought my first MPPT way back in 2017 it's still alive and kicking no problem

My roof is about 10 years from EOL so I'm not super eager to install it today as a full system is about $40,000 in my local market. By comparison I can install this in my backyard in about 45 min simply with hand tools. I will do both eventually but i can do this today and cut about 50% of my air conditioning and beat bill today.

California and Texas are some of the biggest adopters of industrial batteries, and the prices keep plummeting. I remember being near an executive power summit in Idaho back in 2016 and all the execs said industrial power was pie in the sky and would never work. It has virtually resolved all of Australia's power "duck curve" problems. Solar + battery is just phenomenally economical today. China is bringing on NaCl batteries this year and shipping cars with them by EoY. Solar panels are made from beach sand and batteries made from ocean water. Couldn't get any cheaper than that.

We have a sunny, south facing portion of our yard. Looking forward to hanging 4 solar panels on the fence and getting 800-1000w (1200w "nameplate" max but reality is closer to 1000w) to offset our daytime use. We both WFH and then the kids are home by 3pm so being able to offset computers, fridge, and part of our AC/Heat bill is huge.
 
A couple of mfg, Anker and Ecoflow both sell a system that you do the standard 4 x 400w panel = 1200w plug in, and then a second 2000w (+5 more panels) into a battery system that discharges a max of 1200w overnight as the sun sets. I think they want like $1600 for the system. That's an instant buy for me when california electricity is $0.50/kwh
