Wiring (continued)
AC Wiring for Dual-Inverter Installations
Series stacking is used in applications where either 240-volt loads (or a
combination of both 240- and 120-volt loads) need to be powered from the inverters.
One inverter, connected to the utility’s L1 line, provides one 120 volt AC output and
a second inverter connected to the utility’s L2 line provides the second 120 volt AC
output (180 degrees out-of-phase from the first inverter). The combined out-of-
phase voltages can power 240 volt AC loads as well as 120 volt loads, up to the
power rating of the inverters.
NOTE: For full pass-through capability of the inverter,
#6 AWG (90°C) minimum is recommended. Protect the
wire with an appropriately sized breaker.
See Figure 2-8 for a an illustration of input and output wiring for dual-
inverters with dual GTI installations.
See pages 24 through31 for detailed instructions for AC Input and AC
output wiring for dual-inverter/GTI installations.
