Operation

Parallel Stacking (Dual-Stack and Larger)

In parallel stacking, two or more inverters are stacked to create a single, common 230 Vac output.

¾The master provides the primary output. The slaves are connected to the same output and assist the master.

¾The slave inverters can be programmed to activate on demand, reducing idle-power consumption. They will remain off until the loads exceed a certain threshold.

¾A two-inverter system can continuously power 2.6 to 2.8 kVA of loads, depending on the inverter model.

¾Up to ten inverters may be installed in a parallel arrangement. The example on this page shows three inverters.

Three-Phase Stacking

In three-phase stacking, three inverters are stacked to create three separate 230 Vac output legs. These outputs are 120° out of phase. Any two outputs produce 400 Vac between them. The three outputs can be used to power three-phase loads when all inverters work together.

¾A three-phase system can continuously power 3.9 kVA to 4.2 kVA of loads, depending on the inverter model.

¾Only three inverters, one per phase, may be installed in a three-phase arrangement.
