The Currency Wars, From Edison to Enphase

Edison and Tesla Facing off

In the annals of scientific history, few rivalries have sparked as much electricity (pun intended) as the battle between Thomas Edison and Nikola Tesla over the war of currents. Picture the late 19th century: a time when electric power was in its infancy, and two brilliant minds clashed over the future of electrical systems.

The Origins: Edison and DC Power

Enter Thomas Edison, the luminary inventor championing direct current (DC) electricity. His DC system transmitted electricity at a constant voltage, but there was a significant limitation: DC could only travel short distances efficiently. Edison’s vision was limited by the range of his DC power, an obstacle that loomed large in the race to electrify cities.

Tesla's AC Revolution

In stepped Nikola Tesla, an enigmatic visionary whose alternating current (AC) system promised a solution to Edison’s conundrum. AC could be transformed into higher or lower voltages, making long-distance transmission feasible. This breakthrough sparked the AC vs. DC “War of the Currents.”

The Current War Unfolds

Edison, fiercely protective of his DC empire, launched a campaign discrediting AC as dangerous. He even went so far as to publicly demonstrate the dangers of AC by electrocuting animals, tarnishing the reputation of alternating current.

Tesla, undeterred by Edison’s smear tactics, pressed on with his AC system. His partnership with George Westinghouse led to the electrification of cities using AC, winning the bid to power the 1893 World’s Columbian Exposition in Chicago. AC’s ability to travel long distances without significant power loss proved its superiority over DC.

Notice how AC current goes in waves, which make it safer in the event of electrocution and presents a lower fire risk compared to high voltage DC

The Triumph of AC for Homes

Fast forward to today, and the world runs predominantly on AC electricity. Its ability to transmit power efficiently over long distances and transform voltage levels has made it the standard for homes and businesses worldwide.

And now, in the modern era, technologies like Enphase Microinverters take AC safety to the next level. By converting DC electricity generated by solar panels into AC right at the panel level, they enhance safety and efficiency. Enphase Microinverters ensure that only safe, regulated AC power enters your home’s electrical system, mitigating potential hazards associated with high-voltage DC.
