Outback Power Systems GS8048 manual Example of Parallel Stacking Arrangement Three Inverters

Operation

In parallel stacking, two or more inverters are stacked to create a single, common 120/240 Vac bus.

The master provides the primary output. The slaves are connected to the same output and assist the master.

The slave inverters can be programmed to activate on demand, reducing idle-power consumption. They will remain off until the loads exceed a certain threshold.

A two-inverter system can continuously power 16 kVA of loads.

Up to ten inverters may be installed in a parallel arrangement.
