The OutBack true sinewave grid-interactive inverter/charger is a complete power solution. It incorporates a DC to AC sinewave inverter, battery charger and AC transfer switch housed within a die-cast aluminum chassis. The GTFX and GVFX Series Inverter/Chargers give you the ability to sell solar, wind or hydro power back to the utility grid while providing instantaneous back-up power in the event of a utility outage. Our built in transfer switch automatically disconnects your loads from the utility grid and powers them from the inverter in the event of an outage, allowing you to continue using your solar and battery back-up power, unlike traditional grid-tie systems. Intelligent multi-stage battery charging prolongs the life of your batteries and built-in networked communications enables you to stack up to two units while simultaneously communicating with other OutBack Power components. The exclusive modular system architecture means that increased power output is just an additional inverter/charger away. Our GTFX series uses a sealed chassis that can operate in the harshest environmental conditions such as high humidity and corrosive salt air while the GVFX series uses a vented chassis with “bug proof ” screened openings that allow high output AC power various operating conditions.


OutBack Power inverter/chargers are the only choice when you need a true sinewave, powerful, modular and reliable power solution for your home, business or extreme application

Outback GTFX3048 Sealed Inverter is a Grid-Tie inverter. It is a perfect power solution for home and business applications. With the OutBack grid-interactive system, backup AC power is available 24 hours a day. Automatic power-saver at night saves the batteries for longer time period. You can either use it without solar array to provide emergency backup power or create a fully automated system with addition of charge controllers. Encased in aluminum frame, the inverter can operate even in extreme weather condition. The Outback GTFX3048 inverter comes with a standard 2-year warranty with 10-year warranty for California residents.
