Stacking

At OutBack, we adhere to a philosophy that a power system should be fully customizable to address your specic needs. erefore

we set out to create the world’s rst group of inverter/chargers that use a truly modular architecture. is modular architecture uses

the next generation of a technique referred to as “stacking” to enable you to tailor your system for higher output power, increased

charging capabilities and/or three-phase power conguration.

Whether stacked in parallel, classic series, series/parallel or three-phase there is always an inverter/charger which performs the task

of Master. e Master talks to the other units through the HUB system communications manager while performing three major

roles, keeping all inverter/chargers properly phased, controlling inverter and charger output levels, as well as putting unused inverters

into Power Save mode to improve system eciency at low AC load levels.

Parallel Stacking - More power at same output voltage

When the inverter/chargers are stacked in parallel all inverter and charger outputs are combined. is means that each inverter’s AC output is

added up to equal your total system AC output, up to 36,000 watts, in phase at the same 120 VAC/60 Hz or 230 VAC/50 Hz output voltage, or

80,000 watts at 120/240 VAC/60 Hz with the Radian Series.

3-Phase Stacking - More power for three-phase loads

ree inverter/chargers can be congured to provide 120/208 VAC or 230/400VAC four wire “WYE/Star” three-phase AC Power. An inverter/charger is

used to power each of the three legs for 3-phase AC power. e loads on each of the inverters do not need to be kept balanced – each phase is independently

voltage regulated.

OutBack Series/Parallel Stacking - More power at all output voltages

Series/Parallel stacking or OutBack (OB) stacking is unique to OutBack inverter/chargers. Never before has it been possible to have inverter/char-

gers balancing loads intelligently between two legs of AC power while seamlessly changing between series and parallel. OB Stacking uses the X-240

auto transformer to balance the loads between the two separate series legs of a system. e X-240 allows AC loads on leg 1 and leg 2 to be powered

by any combination of inverter/chargers within your system. Even if there are only two inverter/chargers, connected in series, they can function as

if connected in parallel. is allows larger AC loads to be operated by a system without risking overloading one of the 120 VAC outputs.

Classic Series Stacking - More power at higher output voltage

Stacking inverter/chargers in classic series provides a system with split phase 120/240VAC. is method does not allow balancing between

separate legs on a system and is can only be used in dual inverter/charger systems without the X-240 Auto Transformer.
