SERIES DUAL FX CONFIGURATION
• This system can continuously power between 4.0 kW and 7.2 kW of 120/240 VAC 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 off
its AC output.
• All FX AC wiring must be sized to handle 60 amps AC or more.
Note:
• Stacking FXs in series means there are FXs directly connected to two legs of a 120/240 VAC input
source, and to two separate 120 VAC output legs.
• In the event of grid failure, each 120 VAC leg can provide the full wattage of that inverter to the loads
on that circuit.
• These series-stacked 120 VAC legs produce 240 VAC between them. In the event of grid failure, they
can provide the full wattage of both inverters to any 240 VAC loads.
• The Slave FX must be programmed through the MATE as a “Classic Slave’” . The FX connected to Port
01 of the HUB is always the Master (1-2ph MASTER).
• Other options must not be selected, with the exception of three-phase operation, which will be
described next.
• Stacked Grid-Tie FXs should not be used with the FW-X240 Auto Transformer.
