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, 60Hz, 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 th e use of the ISC-S cable.
This interface cable is connected to the series stacking port of t he
inverters (see “Inverter Stacking Control – Series (ISC-S) Cable” on
page 2–29).
