Three-Phase Stacking (Three Inverters)

In three-phase stacking, inverters are stacked to create three AC outputs in a wye configuration.



The three outputs operate independently of each other. Each can run in independent Search mode if

desired, although this does not normally occur when three-phase loads are connected.



Each output is 120° out of phase from the others. Any two outputs produce 400 Vac between them. (This

voltage is nominal and may vary with output settings.) The outputs can be used to power three-phase loads

when all inverters work together.



Only three inverters, one per phase, may be installed in a three-phase arrangement when using the HUB4 or

HUB10 products. Up to nine inverters, three per phase, may be stacked when using the HUB10.3.
