  • Intelligent battery charging
  • Sealed chassis for harsh environments
  • Corrosion-resistant internal components
  • Standard 5-year warranty

OutBack Power’s true sine wave grid-interactive inverter/charger is a complete power solution.

It incorporates a DC to AC sine wave inverter, battery charger and AC transfer switch housed within a die-cast aluminum chassis. The GTFX and GVFX Series Inverter/Charger gives you the ability to sell solar, wind or hydro power back to the utility grid while providing instantaneous backup 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 backup 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 environment conditions such as a 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 in various operating conditions. OutBack Power inverter/chargers are the only choice when you need a true sine wave, powerful, modular and reliable power solution for your home, business or extreme application.
