Including those periods of time before men had ready sources of electricity?
After the powerful rich world's Elite decided to also save the people among whom I was born and live (as many other peoples were saved and their countries were destroyed), the mains supply (220V, 50Hz) in my city became something in the past while it lives the terrorist daily attacks, for about 5 years. Now, things are much better, the mains supply are provided for about 4 to 6 hours daily. Therefore, my main products, since year 2011 till now (and during the terror time) are various DC to AC inverters and what could be related to solar panels (as the controlled chargers of acid batteries).
