    As usual there is absolutely no mention whatsoever anywhere in any of the articles I can find or from the company themselves about what the fucking price is

        Since they say they’re putting them out from 48V to 800V, 48V is what most inverter systems use, so I imagine they’re targetting that size for “consumers” at the single-house PV system size. If the cycle counts and low temperature charging characteristics come true, they will be popular.

        American manufacturers like this like to shoot themselves in the foot by pricing their new and innovative battery technology at the datacenter customer size, find out they have no market, use up all their capital, then sell the tech to a big Chinese company like BYD or CATL. So once they’ve complete this lifecycle, I’d expect a couple more years before they’re readily available to actual consumers. Probably expect to see them then at about LFP prices, like $90/kWh wholesale price.

          48 volts is also what telecom uses in their infrastructure. That’s a much bigger market (and one with deeper pockets) than consumer installs.

            Then why bother putting the article here? Who out of us is going to actually care. I’m looking to expand the storage on my off-grid property and I would absolutely love something other than lithium especially if it can get cheaper per kilowatt hour. I got five acres to work with so I really don’t care about the density just needs a decent cycle life and price

              Thats great that you are looking for alternatives, but you aren’t the only reader here.

              Other people have other interests and are looking for different things than you are.

              Because it’s interesting regardless of whether I can buy it or not?

              I watch reviews on computer hardware that I definitely can’t afford, because it’s interesting.

              It’s a great development that we should keep our eyes on, as some years into the future it will most certainly be available for regular consumers, including you with your install.

      These aren’t for you to buy directly, they are for manufacturers to negotiate a price and order in bulk from the company to then integrate them into their products or production facilities.

      Late last year they were talking about $40 for a KWH which compared very favourably to LifePO4 that was more like $130 at the time and Li-ion that was more like $200. However right now on alibaba you can get a 200Ah battery for about $60 and the LifePO4 300Ah are now down in the $50 range which is an incredible drop in the space of 6 months. So in practice they are less dense and more expensive but I think its new technology introduction pricing and at some point it should be about a third cheaper than LifePO4 for the same capacity, all be it a bit bigger and heavier and quite considerably cheaper than Li-ion for the same capacity.

      The small 18650 and other small sized cells have started appearing on aliexpress as well so its possible to get those too butt they are a lot more expensive than a basic Li-ion 18650 at the moment for a lot less capacity. I think its mostly the bigger cells that most people interested in Sodium Ion will be wanting (home battery and grid storage solutions and some of the low/mid range cars) more than small cells since typically the smaller stuff you want to maximise capacity even if it costs a bit more and most will want li-ion and ideally the newer nearly solid state li-ion that doubles capacity per KG.

        You also have to remember these are specifically designed to favor charge cycles over capacity… Only for stationary
