You are asking for sources, but you are also just giving your opinions, based on your experience. That's not a source. What are we talking about here, anyway?
If the US takes Greenland, NATO breaks up and US troops are no longer welcome in Europe. Are you telling me the US are fighting in Greenland and try to conquer Europe at the same time? If Europe will be attacked by the US it will be considered a pariah state. They will have to turn diabolically evil and take over every western state. And if they don't succeed taking Europe they will have lost their strategic bases.
I still hope that the US military has leaders with a spine, who will not follow those orders. But that hope is fading away quickly.
But what do I know. I have no experience in military strategy. Those are just thoughts that came to mind. I was triggered that this discussion wandered far from it's original starting point.
Focusing only on the inverter brand isn’t enough. The origin of the internal components matters just as much.
I recently read an article (March 2025) about Asian (read Chinese) PCBs and the security risks involved. One key finding was that it is technically possible to embed additional components inside the inner layers of multilayer PCBs, such as espionage chips or sabotage elements (e.g. fuses that can short a circuit). These can be extremely hard, sometimes impossible, to detect—even with X-ray inspection. The article also describes how subtle design weaknesses can enable side-channel attacks that leak information via physical or logical side effects rather than direct data access.
On top of that, there have already been documented cases where undocumented communication devices were found in Chinese-made solar inverters—hardware that was not part of the original design:
This means an inverter doesn’t even need an active internet connection to be a potential risk.
In a worst-case scenario, manipulated inverters could theoretically be used to disable large numbers of PV systems at once, potentially destabilising parts of the power grid. That’s why the EU security discussion should not stop at “Chinese inverters” but extend to the full supply chain, including PCBs and embedded components.
That's why my wife is raw dogging the internet. I excluded her devices from Pihole after i heard too much "site x is not working". She bought from some fake shops. I didn't, thanks to our block list.
Hama’s business model kinda depends on a limited selection in real-world stores, because they’re really only cheap(er) if there isn’t much choice.
I totally agree.
Früher sind Politiker zurückgetreten, wenn sie was verbockt haben. Da waren viele Arschlöcher dabei, aber zumindest haben sie irgendwann Konsequenzen gezogen (wenn auch oft nicht freiwillig). In der Wulff-Affäre ging es unter anderem um Vorteilsnahme von 400 Euro. Auch um eine Unterdrückung der Berichterstattung, aber die 400 € haben ihm glaube ich politisch das Genick gebrochen wenn, ich mich nicht falsch erinnere (was gut möglich ist).
Herr Spahn verprasst Milliarden und bis heute habe ich noch keine wirkliche Entschuldigung dafür gehört. Es sieht sich ja immer noch als Retter und Held. Mir gehen solche Menschen extrem auf den Geist. Und leider sitzen in vielen gewählten Gremien auch viele solcher Politiker.
Wenn wir uns weiterhin solche unanständigen Politiker ziehen, wird das noch böse enden! Die Frage ist nur: wird man so unanständig, je höher man in der Politik klettert? Oder kommen vor allem die Unanständigen so hoch?
PS: es gibt natürlich auch ehrliche Politiker, denen das Wohl der Bevölkerung am Herzen liegt! Aber die sind leider nicht in der Mehrheit befürchte ich.
Dabei zeigen Beispiele in Frankreich und Spanien, dass es funktionieren kann. Dort schreibt der Gesetzgeber vor, dass es keine Verträge unter den Produktionskosten gibt. Dass solche Verträge bald auch in Deutschland gelten, ist allerdings zu bezweifeln. Beim letzten Treffen der Agrarminister in Brüssel hat der deutsche Agrarminister Alois Rainer (CSU) einen entsprechenden Vorschlag der EU-Kommission abgelehnt.
Und trotzdem werden die Bauern weiter auf die Grünen schimpfen!
This is needed! We have to take parts of the pv production back to Europe. But the parts that are included in the inverters need to be European made as well. First because it's the right thing to do. Second because of the risks involved.
I read an article (from march 2025) about asian (read chinese) PCBs and why they are dangerous. The scary part was, that inside the layers of a PCB the manufacturer could hide parts like chips for espionage or fuses to short a circuit that are hard or impossible to detect:
In addition, specific manipulation scenarios are examined. The study demonstrates that it is technically possible to integrate additional components – such as spy chips – into the inner layers of multilayer PCBs. These often remain undetected even during X-ray examinations. Weaknesses in design, such as in the layout of capacities, can also be exploited to enable side-channel attacks. These are attacks that do not directly target algorithms or data, but exploit physical or logical side effects of a system. Attackers observe and analyse these side effects to extract protected information or algorithms.
So the inverter doesn't necessarily need to be connected to the internet.
With such manipulated inverters I guess it could be possible to power down a good chunk of pv generators to destabilize the power grid. This could come in handy for China if they decide to take Taiwan (but this is just a very wild speculation from my part!).
Also disclaimer: this comment is partly recycled from a comment I made a month ago about a simmilar topic.
My old boss called his factory completely made out of concrete sustainable, because he had PV on the roof and fake green plants in the office space. He called it Green Factory. Sadly no /s.
Was ich aus der Grafik lese: dass man mit der maximalen Härte nach unten treten muss! /s
