STACKING OPTIONS

OutBack Grid-Interactive FXs can be stacked in Series or Three-Phase only.

SERIES

• Two FXs are wired to two 120 VAC output legs producing 240 VAC between them.

• Each FX powers one leg and acts independently of the other, but both combine when 240 VAC is

required for a load.

• The AC input must be 240 split phase VAC.

3-PHASE

• Three—and only three— FXs are connected, one to each of three 120 VAC output legs that produce

a nominal 208 VAC between any two legs of the system. (The precise voltages are 127 VAC per leg,

and 220 VAC between legs.)

• The AC input source (generator or grid) must be a 120 VAC/208 VAC 3-phase source.
