Outback FXR/VFXR Renewable Series Installation Manual

Models
Vented FXR (VFXR) models are intended for indoor or protected installation only. Vented inverters
have an internal fan and use outside air for cooling. On average, the power of the vented models is
rated higher than sealed models due to their greater cooling capabilities.
Sealed FXR models are designed for harsher environments and can survive casual exposure to the
elements. However, enclosed protection is still recommended. (See page 15.) Sealed inverters
have an internal fan, but do not use outside air for cooling. To compensate, sealed models are also
equipped with the OutBack Turbo Fan assembly, using external air to remove heat from the chassis.
(Vented models are not equipped with the Turbo Fan and cannot use it.)

Inverter Model Names
FXR series model numbers use the following naming conventions.

The model number includes “FXR” as the inverter series. “R” indicates that the FXR was designed for
renewable applications. Off-grid and grid-interactive functions are integrated in the same inverter.

Vented models are preceded with “V”, as in “VFXR3648A”. If a model number does not begin with “V”, it is a
sealed model and is equipped with a Turbo Fan. This is not indicated otherwise.

The first two digits show the power of that model. For example, “FXR2012A” is 2000 watts.

The second pair of digits shows the inverter’s nominal DC voltage. For example, “FXR2524A” is 24 volts.

The model number is followed by “A”. This designates the inverter’s output as nominally 120 Vac (used in
North America, Latin America, Asia, and other regions).
