Manufacturer Part Number: GVFX3648

OutBack Power Systems GFX's (Grid-tie FX) come in two styles. The GTFX (Grid-tie Turbo FX) is a sealed FX with an external fan to provide cooling and an extra power boost. The GVFX (Grid-tie Vented FX) is a vented FX that intakes air and directs it over the transformer. These GFX's are capable of selling power back to your local utility while giving you the piece of mind of a back-up power system in case the utility fails.

The components necessary to a system involving a GFX are (in order of power flow) the sun, solar panels (or other renewable energy sources), solar charge controller(s), battery bank of the proper voltage and capacity (minimum of 100 amp-hours recommended), the GFX(s), and the utility grid. The utility grid attaches to the GFX at its AC Input terminals.

The GFX comes pre-programmed to operate, even without the Mate. The Mate is necessary to program the GFX (stacking, auto generator start, etc.) and must be connected for functions that involved the clock (advanced generator start) or to view voltage and current meters and Error messages. The Mate is highly recommended for Grid-Tie systems.


  • ZERO watts of AC power draw at night- automatic "silent" sell mode built in.
  • Daily energy production on par with battery-less grid-tie inverter systems.
  • Modular configuration allows easy system expansion and flexible design with up to 10 inverters interconnected.
  • Integrated communication between the inverters and the charge controllers ensure proper operation.
  • Automatically optimizes the conversion efficiency by matching the number of inverters to the amount of power being sold or used.

Detailed Description

Grid Tie/Utility Interactive Capable

Able to sell solar, wind or hydro power back to the utility grid. Reduce your utility bill by spinning your meter backwards!

Provides Utility Back-Up Power

Keeps your lights on when the power goes out as well as other loads like wells, TV, fridge, computer, garage door opener, alarm, etc.

Works Automatically

Built-in transfer switch automatically disconnects the house loads from the utility grid and powers them from the inverter during an outage.

Safe and Approved

Listed to UL1741 standards as a non-islanding power inverter system for renewable energy applications.

Ultra Clean AC Power

Smooth, pure sine wave AC output waveform-not a coarse stepped sine wave or modified square wave.

Intelligent Battery Charger

Advanced charging algorithms provide fast recharging while increasing battery life up to 10 years.

Field Serviceable

Both FX and VFX inverter/chargers can be upgraded or serviced-even in the field.

Networked Communications

All OutBack products can be connected through a HUB to form a network with monitoring and control via a single MATE Display.

Capable Tech Support Help

You can call or email and ask questions of the engineers that designed your products. Tech support doesn't get any better than that.
