Stacking Features
The
$XWR3RZHU
inverter/chargers can support
two stacking configurations. This gives the system engineer
and/or installer more options to work with when tailoring a
system to meet load demands. Multiple inverter/chargers of
different power levels can be installed in a system as stand
alone, parallel stacked, or series stacked.
In parallel stacking mode, two
$XWR3RZHULQYHUWHU
chargers
of the same model can be parallel-stacked. For example, two
$XWR3RZHU
can be stacked in parallel as both units
each have a 12-volt rating and a power rating of up to 2000
watts. See “Parallel Stacking” on page 4
.
In series stacking mode, you may stack two different
$XWR
=
3RZHU
inverter/chargers of different power ratings
$XWR
=
3RZHUDQGZLWK
same voltage ratings. For
example, a
Q
$XWR3RZHU
can be series-stacked with a
Q
$XWR3RZHU
. See “Series Stacking” on page 4

DAMAGE TO INVERTER/CHARGER
Do
not
connect
any
wires
to
the
AC INPUT L2
terminals
on
both
units
at
all
when
stacking
two
Dual
Input
Line/Dual
Output
Line
(DI-DO)
models
such
as
two
"VUP1PXFS
units.
The
same
applies
to
the
AC OUTPUT L2
terminals
on
both
units.
Any
damage
sustained
by
non-compliance
may
damage
the
inverter/chargers
and
void
the
warranty.
The
only
exception
is
AC OUTPUT N2
.
See
“Parallel
Stacking”

Failure to follow these instructions can damage the unit and/or damage
other equipment.
