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 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.

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.
