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.

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.
