Outback Power Grid-Interactive Sine Wave Inverters

Outback Power Grid-Interactive Sine Wave Inverters
Not Recommended For Use With AC Generators

Grid-Interactive? What does THAT mean?? Grid interactive is kind of a hybrid system, battery based but they also feed any excess power back to the grid, and draw from the power grid when the solar panels are not producing enough. The advantages are that you have backup power if the grid goes down, and you can use standard 24 or 48 volt battery systems and solar panels. The downside is higher cost (for the batteries), battery maintenance, and slightly lower overall efficiency (around 91%).

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, and also have the ability to utilize multiple charging sources such as solar, wind and hydropower. The specialized inverters, such as the GTFX2524LA and others are special order, please call our sales office for pricing and lead times.
