Three-Phase Stacking
In three-phase stacking, inverters create three separate 230 Vac
 The three legs operate independently of each other. The inverters on one leg cannot assist another. Several
inverters can be installed in parallel on one leg to power all 230 Vac loads on that leg.
 The output of each inverter is 120° out of phase from the others. Any two outputs produce 400 Vac
between them. The outputs can be used to power three-phase loads when all inverters work together.
 Up to nine inverters, three per phase, may be installed in a three-phase arrangement. (The wiring drawing
on the next page shows only one inverter per phase.) All inverters must be the same model.
