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 GVFX3524 3.5kW 24V Grid-Tie Inverter is a vented inverter that allows you to sell your solar, hydropower or wind back to the utility grid. The vented FX takes in the air and directs it over the transformer. The battery can be recharged using the utility power or the renewable energy resource. AC power can be easily switched using an in-built transfer switch. This grid-interactive system makes sure that backup power is available throughout the day. The built-in auto power save mode ensures that energy from the batteries is not wasted. The networked communication allows stacking two grids FX’s to give 120/240V output.
