Installation
Wiring for a 240
A 240 Vac source does not allow for the connection to the input of a 120 Vac inverter as no neutral line is supplied from the utility or generator. In order to use stacked inverters, a neutral line must be added by using a

1.Run GROUND wires (green):
a)from the AC Distribution Panel to the primary earth/ground connection.
b)from the generator ground to the AC Distribution Panel ground.
c)from the ground terminal in the Autotransformer to the AC Distribution Panel.
d)from the AC Distribution Panel to the Ground bar in the L1 inverter.
e)from the AC Distribution Panel to the Ground bar in the L2 inverter.
2.Run NEUTRAL wires (white):
a)from the
