Xantrex Back Plate for Sine
Wave Plus Power Panel
Installation Instructions
Installations
Xantrex Back Plate (XBP)
A two-piece, steel back plate is available for creating a unified power panel using
one or two Sine Wave Plus Inverter Chargers. The combined panel is designed to
accommodate the following components:
• one or two Sine Wave Plus Inverters, or
• one Sine Wave Plus Inverter and a TX Autotransformer
Plus:
• one AC Conduit Box-Long (ACCB-L), and
• one or two DC Conduit Box-Long (DCCB-L). Two DCCB-L s requires the
XBP-DC.
The primary panel comes in two parts and measures 46" (89 cm) wide when
assembled. If a second DCCB-L is going to be used, an optional plate (XBP-DC)
attaches to the right side of the primary panel to extend it to 60” (152.5 cm).
The back plate comes with mounting hooks that can be attached to the panel to
hang the components on as they’re installed. It also has conduit pass-thrus for
both the ACCB-L and DCCB-L wiring.

Xantrex Back Plate
Panel Components
The panel is comprised of two plates that fit together and combine to create a solid
support for the power system. If dual DCCB-Ls are to be installed, then an
extension plate (XBP-DC) is available to complete the panel.

Attaching the Mounting Hooks
To attach the mounting hooks on the panel, following the procedure outlined in
Figure 1-6.
Installation Instructions
1. Place the mounting hook into the hole
provided so that the back of the hook rests
against the panel and the front of the hook
protrudes toward the front.
3. Secure the mounting hooks with the two 1032x½ phillips screws provided.
2. Align the mounting hooks with the predrilled holes in the panel in the positions
required by the components in your
installation.
4. Torque to 32 inch-pounds.

Mounting the Power Panel
These instructions are for light wood-framed structures such as those commonly
found in residential construction. See local building regulations to ensure code
compliance.
Determine total weight
Due to the size and weight of power panel systems, it is extremely important to
consider the strength of the structure to which it will be attached. Use Table 1-1 to
determine the weight of all components intended for installation. At a minimum,
any basic power panel configuration will weigh approximately 270 pounds.
Component
1- XBP Panel (left and right) 54 pounds
1-SW Plus Inverter / Charger 140 pounds
1-ACCB-L 24 pounds
1-DCCB-L 33 pounds
Miscellaneous Hardware/components ~10 pounds
Minimum Weight to Plan For ~270 pounds
Approximate
Weight
CAUTION: Structural Damage
If you are not sure if the wall is strong enough where you want to install the Power Panel
and it’s components, consult a structural engineer for a second opinion and/or
recommendation.
Wallboard is not sufficiently strong to support a Power Panel system. Wall studs
alone are not sufficiently strong enough to support a Power Panel system that
weighs over 300 pounds.
It is recommended that a 3/4-inch sheet of plywood or 3/4-inch APA rated
sheathing be attached directly to the wall studs from the floor to approximately 12
inches above the top of the intended height of the panel. If wall studs are placed at
16" on center, then the 3/4-inch plywood or sheathing must cover at least 3 studs.
If wall studs are placed at 24-inches on center, then the plywood or sheathing
must cover at least 2 studs.
Attach the plywood, or sheathing to the wall studs, using 12d nails to secure the
plywood to the studs every 6 inches.

Weight-bearing or non-weight-bearing wall
It is also important to determine whether the power panel will be mounted on a
load bearing or non-load bearing wall. In general, a load bearing wall is any wall
that carries weight transmitted by other structural members. An example of a load
33 lbs (15 kg) CF Breaker Mounting Plate < 1 lbs (0.5 kg)
< 1 lbs (0.5 kg)
(6:1 and 12:1)
bearing wall is a wall that is carries the weight from an upper floor, a roof, or from
both. A wall that does not carry weight from other structural elements is
considered a non-load bearing wall.
If in doubt contact a licensed structural engineer to help you make the
differentiation.

Mounting the Panel to the Wall Studs
To prepare the mounting surface:
1. Determine what height you want the top of the panel to be at.
2. Place a piece of 3/4" plywood from the floor to 12-inches above the desired
height of the panel. If the wall studs are 16" apart, then span the plywood
across three studs. If the wall studs are 24" apart, then span the plywood
across two studs.
3. Secure the panel to the wall studs using 12 (12d) nails (or equivalent) spaced 6 inches apart.
Wall Studs

If the wall studs are 16"
apart, then span the
