Hello A trowel with a bell - an innovative tool in the current construction boom can be an interesting idea :) The power of peace in mobile phone service. Adjustable feet for use in technical construction. A starter for a Stiga petrol lawn mower. A shaft for a large circular saw. An interesting radio station remembering the old days. Parts for a motorcycle from the times of the Polish People's Republic, i.e. WSK :) Test of a prototype inverter without a battery, off-grid system, i.e. when the sun shines, we have electricity, when it doesn't, we don't :) How does it work and what can it be used for? What are the design flaws at this stage? To sum up, the device for small independent photovoltaics is ideal, but under certain conditions. What are they? The second part of the film tells about it.
