Stacking Features
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 Neutrals 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.

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.
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.
