A solar/wind "hybrid" electric system combines wind and solar technologiesto deliver non-intermittent electric power. Because the peak operating times for wind and solar systems occur at different times of the day and year, hybrid systems are more likely to produce power when you need it. Hybrid inverters usually operate bi-directionally which means converting DC power from solar modules to usable AC power and then converting stored AC from the batteries to power loads when needed. Solar-wind hybrids can operate as grid-connected or off-grid power sources.
