Outback Power VFX Series Installation Manual

SERIES/PARALLEL QUAD FX SYSTEM

• All AC wiring from the AC source and to the AC loads must collectively handle 120 amps AC or more.

• All other AC wiring must handle a capacity of 60 amps AC (Mobile FX AC wiring must handle 30

amps).

• This system can continuously power up to 14.4kW of loads depending on which model is used.

• Connecting more power than the continuous rating of the FX may cause breakers to trip or the FX

to shut o its AC output.

• A HUB, MATE, and FW-X240 must be connected to successfully stack these FXs in series/parallel.

NOTES:

• Program the lowest-installed FX as the Master (1-2ph MASTER), the  rst Slave as an Outback L1 Slave

(OB Slave L1), and the second and third Slaves as OutBack L2 Slaves (OB SLAVE L2) as shown in the

MATE User’s Manual.

• An FW-X240 Auto Transformer must be used when three or more FXs are series stacked.

When the FXs are connected in series for 120/240VAC, the FW-X240 Auto Transformer can

be connected to the two AC output legs to provide all FX capacity to either of the 120VAC

output circuits. This allows higher e ciency and better performance as heavy 120VAC loads

are powered by all the FXs.

The FW-X240 Auto Transformer also allows the Master to power loads on either of the

120VAC output circuits with the Slave o . This reduces the idle power consumption and

improves the system e ciency.

PARALLELED QUAD FX SYSTEM

• All AC wiring from the AC source and to the AC loads must collectively handle 200 amps AC or more.

• All other non-Mobile FX Series Inverter/Charger models’ AC wiring must handle a capacity of 60

amps AC.

• This system can continuously power up to 14.4kW of loads depending on which model is used.

• Connecting more power than the continuous rating of the FX may cause breakers to trip or the FX

to shut o its AC output.

• Refer to Parallel/Dual System drawing on page 28 and expand accordingly.

NOTES: Program the lowest-installed FX as Master (1-2ph MASTER) and the three remaining FXs as

OutBack L1 Slaves (OB SLAVE L1)

Grid-Tie FXs cannot be used with this configuration.
