I was talking about NMC Li-ion batteries, not LiFePO4 Li-ion batteries! if you are talking about LFP, then i'm totally wrong, they are safer than Na batteries. In that case the only thing that Na MAY be better is price (probably only after being well established and with higher capacity)

Many years ago people used lead-acid batteries for solar, them Li-ion and only now they are using LFP.

Everytime i said Li batteries , i'm thinking in the normal Li-ion, while i know that LPF is also Li-ion, just in a different way, but i call those LPF or LiFePO4

There are 2 reasons for the default not be "you can do whatever you want in your home":

- Safety, Hygiene. Something new is likely to have some unknown dangers. The closer you are to other people, the more restrictive things get. Again, you may think it is your home, but many things may affect people around. noise, A 50m high pole, fire, noise are easy to detect, but others are harder like material used can pollute the water or the air and others are just strange, like magnetic fields, electricity, electronic emissions.
- Politics, Monopolies, Lobby, Money. Another reason can be political, Monopoly pressure, Money that can be gained or saved. Telcos had special rights for many years, so as electrical companies (many still have). If it is something that saves you money and is forbidden, follow the money and see who wins by not allowing you to do that.

Of course all this applied to normal humans, companies/enterprises/billionaires can do whatever they want, they just need to bribe^Wconvince some politics and/or have good lawyers. A normal people isn't allowed to mess with unknown things, but a chemistry company can produce a new product with some quickly made reports paid by then reporting it is totally safe ... and 10 years later we all find out that it isn't after all

>A company can sell for what ever price it wants.
Sort of... They can choose to produce/sell or not produce/shutdown. The price itself in the EU is enforced to be calculated the same way, as marginal pricing. That is, the price that each one received is the price of the last producer need to meet with the demand.
Say you ned 400MWh and you have this producers available

Generator __ Cost to produce 1 MWh _ Available __ Accepted?
Wind _______ €10/MWh ___________ 100 MWh __ 100 MWh
Nuclear _____ €20/MWh ___________ 200 MWh __ 200 MWh
Gas ________ €80/MWh ___________ 150 MWh __ 100 MWh
Coal _______ €100/MWh __________ 100 MWh ___ 0 MWh

The marginal pricing would be 80€/MWh, because wind and nuclear both account for 300MWh, add the Gas for more 100MWh, you get the 400MWh already, no need to buy from the Coal producer. The last price is 80€/MWh and is what all producers receive. So solar receive 80€ when it cost was really only 10€, gas received 80€ and it was it own price. Coal gets nothing as didn't sold any capacity

This is set to promote cheaper sources and the more expensive ones to be more flexible. This price is calculated in each country and as they are all connected, you also add the next country production to your list. So while you can set your price, what you get is defined by these marginal prices in your country.

This is why companies invest in wind and solar, they are cheaper and faster to deploy, can get paid back quickly. A nuclear plant can take huge amount of years to build, costs a fortune and have a return of investment way longer, while can sell much more capacity.

Notice that marginal pricing in electricity happen all over the world, with some small changes, like also accounting transmission costs in bigger countries/weaker distribution capability

yes, of course, it is just the cost of the hardware to have a extra socket... the problem may be the capacity/power of that... probably better is to get a bluetti or jackery, that can spike when turning things on and the lower to normal levels. But all depends in the way you want to use it

i said safer, not bullet proof! Even a lead/acid battery is dangerous if you do stupid things!! Even water container can be dangerous , like dropping it from the 3th floor!!

maybe you have older models, recent ones were even sealed in epoxy like glue, so almost impossible to reach!
Dyson was awesome, but slowly they changed: https://dysonmedic.co.uk/from-...

i didn't follow up the glued vacuum story, they may have changed their minds and stopped doing that, but blocking easy repairs means more sales (at least in short term, long term people will slowly migrate to other solutions)

exactly, for those cases, you have house wide batteries and be charged by either the solar or grid energy

yes, your Post-It® is safe in my encrypted photo repository, don't worry, only me can access it!! :D

are you sure you didn't meant "please deliver it to my home", as for sure you will be lazy enough to even order one, right?! :D

the user should be a idiot, so he will floss slowly too, giving enough time

The idea is to use both!! not one replacing the other!!

and repair...

You have to understand that your freedom ends when another one freedom is reach!

you home is your home, right, but you power grid is connect to everyone power grid. if you mess with your grid in a bad way, you risk causing issues to everyone grid or even fires. Those systems need to be well planed and certified. For big setups, that require lot of paper work, for these small systems, they are simplifying the setup, as long you follow those rules. So if you buy a certificate system, you are good, if you build your own, also good. If you mess up, you can blame the producer of the certified system on the first and have the full blame on the second

So if your home is connected to the grid, you have to follow rules, you can't block your panel energy from interfering with the remaining grid.
I can't also build a cell phone tower in my home, as there is no way to block those signals from interfering with other towers

Also, if your home is disconnected from the grid, THEM you have the freedom to add whatever you want, you do not need this special permit (of course always within the limits that may exist, you can't install a home nuclear reactor, even if outside the grid!!)

Exactly that was one of the problems of the Spain/Portugal blackout, with power going down in some parts, most existent solar and wind setups follow the grid within certain limits. When those limits were crossed, they do what is safe and shutdown...no power in, then no power out!
Of course it end making the problem even worse and cascading to the next system. They can be equipped with ways to keep producing and adding inertia to the grid, but almost none had that because no one expected a so big problem and of course, all that costs money! Add that the lacked of special monitoring and tripwires to disconnect entire regions and limit the problem from cascading to the next one made 2 countries and a small region of France without power between a couple of minutes to around 30h

and rename the current Sun to Sun of America, because... who cares, probably because his small ego
