Neutral Wiring for Stacked Inverters
Due to the neutral ground switching design of the
$XWR
3RZHU
L
nverter/charger, it is mandatory that the
AC INPUT
and
AC OUTPUT
1
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.
