PART 2: INSTALLING A SERIES SYSTEM
• Xantrex recommends that you have an electrician set up the two
inverter•chargers because knowledge of the electrical code, split-phase
systems, and load balancing is required.
•See page 18 for a list of tools and materials required for installation. In
addition, you will need a ten foot series sync cable. Contact Xantrex or
your distributor for this part.
•See page 19 and following for information about wire sizes, over-current
protection, and disconnection means.
• Connect the system as shown in Figure 20, on page 85.
Detailed procedures for setting up an AC series system are given below.
Connecting AC Input Wiring
➢
➢➢
➢
To connect each inverter•charger to the utility 120/240Vac split-
phase supply
1. Assign one inverter•charger to Line 1 and one to Line 2 and maintain the
same assignment throughout the AC input and AC output wiring steps.
2. Connect 2-conductor-plus-ground cable to a 30A breaker on Line 1 in the
source panel, and to the panel’s neutral bus and ground bus.
3. Run the 2-conductor-plus-ground cable to the Line 1 inverter•charger and
connect:
• The Line 1 conductor to its AC Input Line conductor (black)
• The neutral to its AC Input neutral conductor
• The ground to its AC Input ground terminal
4. Repeat steps 2 and 3, connecting the 30A breaker on Line 2, neutral, and
ground from the source panel to the input wires and ground of the L2
inverter•charger.
WARNING
Xantrex Technology recommends that all wiring be completed by a
certified technician or electrician to ensure adherence to approved
electrical wiring regulations.
WARNING: Fire, Shock, and Energy Hazards
Make sure wiring is disconnected from all electrical sources before you
handle. All wiring must be done in accordance with local and national
electrical wiring codes. Do not connect the output terminals of the
inverter•chargers
to any incoming AC sources.
