maintenance of this product.
To reduce the risk of electrical shock, and to ensure the safe installation and operation of this product, the
following safety symbols have been placed throughout this manual to indicate dangerous conditions and important
safety instructions.
WARNING - A DANGEROUS VOLTAGE OR CONDITION EXISTS IN THIS AREA.
USE EXTREME CAUTION WHEN PERFORMING THESE TASKS.
AVERTISSEMENT - UNE TENSION OU CONDITION DANGEREUSE EXISTE DANS
CETTE ZONE. FAIRE PREUVE D’EXTRÊME PRUDENCE LORS DE LA RÉALISATION DE
CES TÂCHES.
CAUTION - This procedure is critical to the safe installation or operation of the unit.
Follow these instructions closely.
ATTENTION - Cette procédure est essentielle à l’installation ou l’utilisation de l’unité en
toute sécurité. Suivre ces instructions de près.
NOTE - This statement is important. Follow instructions closely.
NOTE - Cette déclaration est importante. Suivre les instructions de près.
•All electrical work must be done in accordance with local, national, and/or international electrical codes.
•Before installing or using this device, read all instructions and cautionary markings located in the manual, and
on the inverter, the batteries, and the PV array.
•Do not expose this unit to rain, snow or liquids of any type. This product is designed only for indoor mounting.
•To reduce the chance of short-circuits when installing or working with the inverter, the batteries, or the PV
array, use insulated tools.
•Remove all jewelry while installing this system. This will greatly reduce the chance of accidental exposure to
live circuits.
•The inverter contains more than one live circuit (batteries and AC line). Power may be present at more than
one source.
•This product contains no user-serviceable parts. Do not attempt to repair this unit.
•Do not install 120 volt AC stand-alone inverters onto 120/240 volt AC multi-branch circuit wiring. This could
pose a fire hazard due to an overloaded neutral return wire in this configuration.
•When stacking inverters, always connect the chassis of each inverter together using the chassis ground lug;
otherwise, a hazardous voltage may be present between each chassis.

BATTERY SAFETY NFORMAT ON
• Always wear eye protection, such as safety glasses, when working with batteries.
• Remove all loose jewelry before working with batteries.
• Never work alone. Have someone assist you with the installation or be close enough to come to your aid
when working with batteries.
• Always use proper lifting techniques when handling batteries.
• Always use identical types of batteries.
• Never install old or untested batteries. Check each battery’s date code or label to ensure age and type.
• Batteries are temperature sensitive. For optimum performance, they should be installed in a stable
temperature environment.
• Batteries should be installed in a well vented area to prevent the possible buildup of explosive gasses. If the
batteries are installed inside an enclosure, vent its highest point to the outdoors.
• When installing batteries, allow at least 1 inch of air space between batteries to promote cooling and
ventilation.
• NEVER smoke in the vicinity of a battery or generator.
• Always connect the batteries first, then connect the cables to the inverter. This will greatly reduce the chance
of spark in the vicinity of the batteries.
• Use insulated tools when working with batteries.
• When connecting batteries, always verify proper voltage and polarity.
• Do not short-circuit battery cables. Fire or explosion can occur.
• In the event of exposure to battery electrolyte, wash the area with soap and water. If acid enters the eyes,
flood them with running cold water for at least 15 minutes and get immediate medical attention.
• Always recycle old batteries. Contact your local recycling center for proper disposal information.

SW Stacking nterface 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 u e a tandard computer cable in place of the SWI tacking interface
cable.

Series Stacking
The STACKING port allows two SW or PS Series inverter/chargers to be used in the same system in a “SERIES”
configuration to operate 240 VAC loads. Series stacking can also be used to connect to 240 VAC only power systems
providing both 120 and 240 VAC outputs. A series stacking interface cable (SWI) is required to connect the series
stacking port of the inverters. In this mode, the inverters act independently of each other; however, their output is
phase locked and synchronized 180 degrees out-of-phase. Both units can independently charge the batteries or
provide battery backup power during a utility outage. 230 VAC/50 Hz units can not be stacked.
NOTE: se tape to label the inverters as INVERTER 1 (L1) and INVERTER 2 (L2), for future
reference.

The STACKING port allows two SW or PS Series inverter/chargers to be used in the same system in a “SERIES”
configuration to operate 240 VAC loads. Series stacking can also be used to connect to 240 VAC only power systems
providing both 120 and 240 VAC outputs. A series stacking interface cable (SWI) is required to connect the series

NOTE: se tape to label the inverters as INVERTER 1 (L1) and INVERTER 2 (L2), for future
reference.
Series Stack DC Wiring (one disconnect device)
When stacking two inverters using one DC disconnect device, connect the units and batteries as follows:
• Tie the inverter’s negative terminals together using an appropriate length of cable (sized to fit).
• Connect one of the inverter’s negative terminals to the negative terminal of the battery bank.
• Tie the inverter’s positive terminals together using an appropriate length of cable (sized to fit).
• Connect one of the inverter’s positive terminals to the DC disconnect.
• Connect the DC disconnect to the positive terminal of the battery bank.
• Connect the Series Stacking Cable (SWI) to the STACKING port of both inverters.
• Connect the DC chassis ground lugs of both inverters together using a heavy gauge wire.
• Connect the negative end of the battery bank to a solid earth ground (refer to inverter installation manual).
NOTE: Connect the positive and negative wires to the batteries as show in the illustration
below. This ensures an even charge and discharge through the battery bank.
