Actually, the newer ones don't. Both the batteries are better and the charge controllers are better at detecting when the batteries are getting closer to their limit. Then there's the # of batteries that matter.
For example, I have 18 solar batteries each able to produce 5.14kW, all of them on a common bus. My inverters, however, draw a max of 18kW of continuous power (anything above that my inverters pull from the grid even if my batteries are fully charged). Thus, each one of my batteries at most have to produce only 1kW (the 18kW max my inverters will pull, spread equally among the 18 batteries). Basically each battery at most has to produce less than 20% their max capacity. A nothing burger. The same with power flowing the opposite direction when charging the batteries. Even when I get the max from my 20kW of solar panels, it's spread out evenly to charge 18 batteries. Right now my solar is taking in 14.3kW. After some of that is used to power the house's load (among other things my wife's running the clothes dryer) that leaves 10.5kW going to the batteries to charge them. Divided by 18 batteries means less than 600W each to charge each of them -- a drop in the bucket compared to the charge level they can handle.
Also each battery now has BMS built in (battery management software) that, among other things, looks at the temp of the battery. On top of that my inverters/charge controllers also monitor that. So if a battery is getting tired either the battery's BMS or my inverters or both will slack off and send me an alert.
And when your hydrogen storage is full you can fill weather baloons cheaper than helium.
I can’t believe all Oreganites aren’t mad as all get out over the balloons from China. The people of Oregon have a history of being victims of Fu-Go balloons from Japan during World War II.
I just noticed a story about the dearth of qualified electricians for all of the ‘electrification’ of America.
FTA: “”Electricians say they are booked several months out and struggling to find enough workers to keep up with demand. Many are raising wages and prices and worried that they won’t be able to keep up as government climate incentives kick in.””
Frackin’ “government incentives”
Once again, taxpayers are finding this insanity. Without government $$$, there is no ‘demand’ no ‘market.’ Every time I see an EV, I remind whoever I am with that we funded part of that purchase. Most of the buyers have more than a few dollars, and we are finding their second or third auto.
I worked in a town just outside of Sacramento, Kalifornia. There was this solar company that had set up their business in a few buildings. A farmhouse, a shed, and a larger structure. There were a few vans and trucks. I drove by it at least twice a day, sometimes more. Many signs and posters touting the State and Federal tax incentives (taxpayer $$$, you and me). Within a week of the end of the subsidies, the company did not just close, there was no evidence that it ever existed. The buildings were still there, just as they were before the ‘subsidies.’ No signs, no posters, no trucks, no vans. For any after-purchase follow up, the customers were SOL. Perhaps I will make a large sign for the building: Solyndra Was Here.
