2.5.6 AC Wiring Confi gurations (MS2012, MS2812, MS2024, MS4024, & MS4048)
The following table provides the different wiring confi gurations for installing and connecting the AC
conductors to and from the inverter (refer to Figures 2-11 to 2-15 for installation drawings showing
these confi gurations). Refer to Table 2-4 (and Figures 2-16 & 2-17) for the MS2000 models.

Reason to
Use
Have an 120
VAC source that
is ≤30A.
Requires
a separate
inverter
sub-panel.
Have an 120
VAC source
that is >30A.
Requires
a separate
inverter
sub-panel.
A separate
inverter sub-
panel is not
required for -XXB
models.
Inverter pass-
thru capability
limited on each
leg by model
used.
Want dedicated
charging and
dedicated
pass-thru while
the AC source
is on.
Requires
a separate
inverter sub-
panel.
May need to
power 240
VAC loads
if AC source
on (requires
120/240 VAC
source).
Requires a
separate inverter
sub-panel.

Note
1
– AC source is from either the utility/grid power (i.e., shorepower) or an AC generator.
Note
2
– If two legs of 30A @120 VAC used, they must be from the same source (i.e., common
neutral). For example, 2 legs from a 3-phase source can be used.
Note
3
– These MS Series models require a sub-panel for this particular confi guration.
