Normal electric utility frequency is 60 hertz (Hz). During a grid outage, Powerwall effectively establishes grid quality power (120/240 volts at 60 Hz), allowing a nano grid to operate at your home. . Solar power frequency typically refers to the rate at which alternating current (AC) is transmitted, commonly operating at either 50 Hz or 60 Hz in most regions. Current usage by country or region is given in the list of mains electricity by country. This means that the power is completing a full cycle of its wave sequence 60 times per second.
