2.5.6 AC Wiring Confi guration (ME2012, ME2512, and ME3112 models)
Table 2-3 provides the different wiring confi gurations for installing and connecting the AC conductors
into and out of the ME2012, ME2512, and ME3112 model inverters (see Figures 2-9 to 2-13 for
installation diagrams). Refer to Table 2-4 (and Figures 2-14 & 2-15) for the ME2000 models.

Reason to
Use
Have an 120
VAC source
that is ≤30A.
Requires
separate
inverter sub-
panel.
Have an 120
VAC source
that is >30A.
Requires
separate
inverter
sub-panel.
No separate inverter
sub-panel.
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
separate inverter
sub-panel.
Need to power
240 VAC loads
when AC source
is on (requires
120/240 VAC
source).
Requires
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 are used, they must be from the same source (i.e., common neutral).
