Dual-Inverter Configurations (240 Vac)
If 240 Vac power is required and the wattage required exceeds the wattage
output of a single inverter, it may be necessary to add a second inverter.
Two inverters can be “series” stacked to provide both 120 Vac and 240
Vac, 60 Hz, power to the AC loads.
Series stacking is an excellent choice for providing power to multi-wire
branch circuits where single (120 Vac) inverters may require extensive
rewiring within the building.
See Figure 2-18 for an example of this configuration with all options
shown. Disregard any part of this illustration that does not apply to the
system configuration being installed.
Note:
Series-stacking inverters require the use of the ISC-S cable.
This interface cable is connected to the series stacking port of the
inverters (see “Inverter Stacking Control – Series (ISC-S) Cable” on
page 2–29).
