3000w Low Frequency Off Grid Inverter

GI series :3000w low frequency off grid inverter

      In 1729, Gray of England discovered  the  difference between conductors and insulators while studying whether the electrical effects of amber could be transmitted to other objects: metal conducts electricity, silk does not, and he made the  human body electrified for the first time. Gray's experiment caught the attention of French Diffy.

      In 1733, Diffie discovered that  insulated  metals  can also  be  triboelectrically  charged, so he came to the conclusion that all objects can be triboelectrically electrified. He  called the  electricity produced on glass "glassy", and  the  electricity produced on amber, which was the same as that produced by resin, called "resinous".

      He got : Objects with the  same  electric charge repel  each other; objects with different electric charges attract each other. In 1745, Muschenbroek of Leiden, the Netherlands, invented the Leiden jar, which can store electricity.

     The  invention  of the Leiden  jar provided  conditions for further research on electricity, and it played an important  role in the  dissemination of  electrical  knowledge. At about  the same time, Franklin  in the  United States  did a lot of  meaningful work, which  enriched people's understanding of electricity.
