Stacking Features

This guide for use by qualified installers only.

Neutral Wiring for Stacked Inverters

Due to the neutral ground switching design of the Freedom 
SW Inverter/charger, it is mandatory that the 

AC INPUT

 and 

AC OUTPUT N

eutrals be isolated from one another. In a 

stacked pair configuration, connect the two AC input neutrals 
together at the main distribution panel and the two AC output 
neutrals at an isolated neutral location in the inverter AC 
distribution panel.

IMPORTANT: 

In a parallel-stacked configuration, during operation, the

AC transfer (pass-through) relay rating remains the same at 30 amps. The
AC transfer relay rating does not double to become 60 amps.

Figure 18 

Neutral Wiring for Stacking

FIRE HAZARD

Do not power several loads in excess of 30 amps even in parallel-stacked
configuration.

Failure to follow these instructions can result in death or serious injury.
