Outback FX-R Series Installation Manual

Introduction

Models

Vented FXR (VFXR) models have an internal fan and use outside air for cooling. On average,

VFXR models have higher power ratings than FXR models due to their greater cooling capabilities.

Sealed FXR models 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 FXR models are not equipped with the Turbo Fan and

cannot use it.)

IMPORTANT:

All models, sealed or vented, must be installed indoors.

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).
