Advanced inverters can continue to operate and even assist in smoothing out an increasingly variable grid

Advanced inverters, or smart inverters, are sophisticated versions of the devices long used to convert the direct current output of solar panels into the alternating current used by consumers across the electrical grid. Whereas traditional inverters are programmed to shut off during disturbances on the electrical grid, advanced inverters can continue to operate and even assist in smoothing out an …
