Energy uses
Current trend of the technology :

DC distinguishes itself from Alternating Current owing to the electric charge flowing in a constant direction. Direct Current is native to solar PV electricity generation, battery storage, low-power domestic and commercial applications

Currently known as nanogrids, the number of projects implemented is very low. Returns on investment seem too low in developed countries: gains in terms of energy efficiency are too low compared to the classical AC solution, voltage quality issues may arise, there are significant losses in wiring.? However, the benefits also depend on the penetration rate of IoT, battery, PV panels, EV, smart power systems etc, in domestic settings. Nanogrids are solutions that are definitely being considered in emerging countries due to their ability to be off-grid.
