The OutBack modular "building block" sinewave inverter/chargers can be used for both residential and commercial applications. Each OutBack inverter/charger module is a complete power conversion system - DC to AC inverter, battery charger and AC transfer switch. Additional inverter/chargers can be connected at any time in either parallel (120VAC), series (120/240VAC) or even three phase (120Y240VAC) configuration, allowing the system to be tailored to the specific power conversion requirements of your application. Up to ten of FX or VFX inverter/chargers can be connected together to provide up to 36 kW of continuous power conversion capacity using a HUB10 communication manager and a MATE system display.

The FX series inverter/chargers are designed to survive harsh environments anywhere in the world. Their unique sealed gasketed die-cast aluminum chassis protects the electronics, making them ideal for wet and buggy applications like Baja or Hawaii.The VFX series of inverter/chargers are designed for use in more protected environments. A cooling fan circulates outside air through the inverter/charger to allow higher continuous power capacity. A removeable, washable intake air filter is included with all of the GVFX models. These units provide the most power per dollar and are appropriate for use in most areas of the US. The OutBack GTFX (sealed with turbo standard) and the GVFX (vented) inverter/chargers are approved for grid-tie applications only . Currently a maximum of two of the grid-tie inverters can be series stacked.
