The OutBack VFX2812 inverter is a ventilated version of the original sealed FX series modular "building block" sine wave inverter/charger that can be used for both small and large power systems. By allowing cooler outside airflow through the internal electronics, more AC power is available and operation in extremely hot environments is improved compared to the sealed FX series.

Each OutBack VFX inverter/charger is a complete power conversion system - DC to AC inverter, battery charger and AC transfer switch. Additional FX inverter/chargers can be connected at any time in either parallel (120 VAC), series (120/240 VAC), or three-phase (120/208 VAC) configurations. This allows a system to be tailored to meet the specific power conversion requirements of the application, both at the time of the installation and in the future.

Like the FX series, the OutBack VFX is also designed to survive harsh environments around the world. The full screened vent openings are "bug-proof" and the die-cast aluminum chassis protects and keeps the power conversion components cool in very hot environments even when operated at high power for extended periods. The VFX can be used in high ambient applications up to 60^oC (with reduced output ratings).

The OutBack VFX series inverter/charger system is designed for both residential and commercial stand-alone or back-up power applications with battery energy storage. It is designed to operate as a coordinated system with the other OutBack products such as the Flexware enclosures, the MX60 MPPT charge controller and MATE system controller and display.
