Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear
Agreed. I maybe a radical DC home evangelist but yeah AC has its place still and it being THE standard for home appliances is a good example of the powers of scale.
So far for my home usage I’m standardizing on 48vdc because that is the last multiple of 12 before you go above OSHAs low voltage regs.
From there I really want to standardize further on the power delivery spec, because I just love the idea of smart grid for my home. I can then have dispered batteries in my home for either the primary benefits of that device is portable but doesn’t always need to be (laptop, power tool batteries, little robot thing, car, etc) or as a way to reduce some crazy limited time power draw (like servers starting up, oven running for an hour a day, etc).
From there maybe just Microadapter for a few standard circuits so the outlets work the same.
Personally, a remnant of that. Being able to use standard lead acid batteries is a perk, but primarily I find that that voltage range of < 20-50>vdc in terms of equipment is in those 12v increments too. With the powedelivery (PD) extended power range (epr) going up to 48v right now, and the fixed voltages in that spec being multiples of 12 again matching the industry it is now.
With adjustable voltage supplies (AVS) it might matter less (because it can increment in 100mv instead of a couple fixed voltages) but I haven’t messed with that yet myself

Is the multiple of 12 thing just for ease of lead-acid storage?
