  • I can’t cook. That doesn’t mean that I am not able to when given time and resources and a receipe, that means that the amount of things I can fight through in a day is limited and I need to use that budget wisely, earning money, caring for my dog and seeing to it that my house and garden don’t fall apart.

    That means, I can’t cook, even when it looks like I’m just sitting there, staring into the blue. “You just have to…”, no, you just have to, and the what you have to is “shut up” and “stop using yourself as a reference for everything”.


  • On some level, water would work the same way. If you were to collect water from somewhere, feed it into a pump and hook that up to your kitchen faucet, as soon as you increased pressure a little above that of the public water pipe, water would flow backwards from your faucet through the pipes in the house into the public water supply and your water meter might run backwards, depending on its construction.

    disclaimer: Unlike freshly harvested AC electricity from a solar inverter, home collected water does not meet the hygiene standards for public supply. Absolutely do not do that either.


  • Huh, the wiring just supports power spontaneously coming from an exit point rather than an entry? Is that commonplace?

    Why wouldn’t it? Electrical wiring isn’t a one way road, electricity (this is an extreme oversimplification, especially when it comes to AC) will always flow from points of high voltage to points of lower voltage. That’s how solar inverters feed into the grid. Raise their voltage a tad bit higher than the grid and match the frequency and phase of the grid until the outflow matches their maximum available power.

    Is that commonplace?

    That is a hard question, because this isn’t a feature, it’s how things are. Only thing one needs to take care of is that the solar inverter doesn’t deliver so much power that the circuit can consume beyond the circuit breakers capacity, otherwise the breaker would be rendered useless. That’s why these small plug inverters are limited to 800W in Germany, that puts the entire possible load on a 16A circuit into the general upper limit that is still within the safety margin fro 16A circuits.

    EDIT: Now before someone gets the bright idea to connect their diesel generator to the grid this way: Don’t. It will not be in sync or phase and that will make something spectacular happen, but it will not supply the grid. Either have an expensive generator that is able to sync to the grid or have a grid disconnect and switchover in front of your generator plugin socket.

    EDITEDIT: Also please never connect an island capable solar inverter to a plug. The ones described above are safe that way, because they wait for grid voltage to be available before they do anything, so there will never be high voltage on the open plug. An island capable solar inverter does by definition not do that. There will be high voltage on the plug and it will kill you and it will hurt like a fucker the entire time you’re dying.











  • Its the fact that we are mandated to sell the excess to EU before we take care of our own.

    That doesn’t really work that way and there is no forcing involved. Capacity is sold by the power plant operators and bought by the power companies who resell it then. As long as neighbouring zones pay more than Southern Sweden, power plant operators in Southern Sweden will sell their generation capacity at that higher price because they are not a charity but for profit companies.

    Now, grid operators in Southern Sweden could show them the middle finger and buy capacity from Central Sweden, but that’s apparently not possible because not enough power lines exist to actually transfer the energy from there. So, grid operators in the South are stuck with the higher prices that someone else pays as well.

    And even if you just want to blame the Germans for everything, check the distribution of exports from the South Sweden zone before making that claim: https://app.electricitymaps.com



  • EPEX SPOT SE is a company under European law based in Paris (France) with offices in Amsterdam (the Netherlands), Berlin (Germany), Bern (Switzerland), Brussels (Belgium), London (United Kingdom), and Vienna (Austria).[1] It operates the power spot markets for short-term trading in Austria, Belgium, Denmark, Finland, France, Germany, Great Britain, Luxembourg, the Netherlands, Norway, Poland, Sweden and Switzerland.

    Not to mention that the eu mandated market zones only applies when you aren’t Germany, because of reasons.

    I don’t see yet how one would arrive at that conclusion regarding EPEX. Please explain.
