1.0 INTRODUCTION
SWI Stacking Interface Cable Kit
The SWI Stacking Interface Cable is an accessory for SW and PS Series inverters. This cable allows the AC
output of two (identical) inverters to be connected in a series configuration, providing both 120 and 240 VAC, 60 Hz
power for the loads. The AC input to the inverters is provided by the L1 and L2 legs of the utility grid (or 120/
240 VAC generator) with L1 connected to the input of one inverter and L2 connected to the corresponding input of
the other inverter (i.e., AC1 of both inverters).
Stacking is also an excellent choice for providing power to multi-wire branch circuits where stand alone
(120 VAC) inverters may require extensive rewiring within the building.
The SWI Stacking Interface Cable kit consists of:
• This Installation Guide
• One 42-inch stacking interface cable, complete with two 25-pin D connectors
CAUTION: Do not use a standard computer cable in place of the SWI stacking interface
cable.
