Emergency backup power with the SMA Sunny Boy inverter series
If you have a home solar system, it won’t keep your house powered in a blackout unless you have a battery system. This is because solar inverters have a feature called anti-islanding. A solar inverter converts direct current (DC) power from solar panels into alternating current (AC) that your home and electric grid use. AC power has a frequency of 60 hz in North America. In normal operation, your solar inverter “listens” for power from the grid, and synchronizes its AC output to that of the grid.
