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” on page 4 .
Failure to follow these instructions can damage the unit and/or damage
other equipment.
