Grid-Interactive renewable energy systems enable you to demonstrate your personal commitment to a renewable energy future. With the OutBack grid-interactive system, backup AC power is made available 24 hours a day in the event of a utility outage, providing reliable power and peace-of-mind. At night, the inverter's automatic power save mode ensures that energy is not wasted by needlessly charging your batteries from the utility grid. An average conversion efficiency of 91% using the California Energy Commission (CEC) test protocol provides greater savings and a shorter time period for system payback. OutBack's grid-interactive technology provides you more than a typical solar inverter, we also have an unmatched ability to utilize solar, wind and hydropower sources.
