We have only used components from large-scale industry in the manufacture. Affordable and high-performance parts that have proven themselves over a long period of time. The technology as such is handmade, not electronic high-tech madness.
Learn from the power4you technology and change your consumption behaviour. Use large consumers one after the other, not unthinkingly as if the world costs nothing. Everything costs! Especially your energy, even if self-generated and cheaper. Yes, we will colour you green.
