A great example is this simple wireless AC current detector from [NEW PEW]. The circuit is a simple one, and a classic. The spring from a ballpoint pen is soldered to the base of a BC547 ...

This, however, is not the case, as they need around 100 volts of AC current to allow them to light up. For a battery-powered solution, this means converting the battery’s DC power to AC.

Utility-scale solar is set to crank up the voltage, preparing to shift from 1.5 kV to 2 kV on the DC side. It is a move that could redefine PV system design and slash costs, but it won’t happen ...
