Communication Overview
Users can communicate with the SOLECTRIA XGI 1000 using a WiFi enabled smart device, such as a laptop,
tablet, or smartphone. The SOLECTRIA XGI 1000 monitors internal variables (see Section 5.2.1). This data is
sent via a modem or gateway to the Internet cloud. In the cloud, this data is stored on the SRV server where it
can be accessed by the end user (additional fee applies). Add-ons such as a weather station and a Data
Acquisition System (DAS) are supported using Ethernet cable.

2.2 Inverter Placement
Inverter Environment
The SOLECTRIA XGI 1000 inverter is rated for outdoor use and will operate properly when exposed to direct
sunlight, rain, or snow. To optimize the performance and longevity of the inverter, mount the inverter out of direct
sunlight.
Inverter Orientation
It is recommended to install the inverter facing north to minimize direct sun exposure.
Figure 2-4 Acceptable Inverter Environments (Left to Right): Shaded, Direct Sunlight, and Rain

Inverter Mounting Angle
The acceptable mounting angle range is 5 to 90 degrees measured from horizontal, as shown in Figure 2-5.
Make sure the Wiring Box is below the Power Head. Regardless of the installation angle, the bottom edge of the
Wiring Box must be parallel to the ground (no side-to-side tilting).
Figure 2-5 Inverter Mounted Correctly Between 5 and 90° from Horizontal and Level to Ground
Do not install the inverter with the Power Head below the Wiring Box nor with the base of the Wiring Box not
parallel to ground.

Mounting
Mount the bracket to a flat surface capable of supporting 186 lbs. (84.4 kg). Acceptable surfaces include
concrete, drywall, or other nonflammable surface as long as they can support the weight specified. Structural
integrity of the mounting surface is the responsibility of the installer.
The Mounting Bracket comes in three pieces. Align the holes at the center of the top and bottom pieces with the
studs on the middle piece. Use the four nuts to connect the pieces and tighten them. See Figure 3-3.
Figure 3-3 Bracket Assembly

Installation and Operation Guide SOLECTRIA XGI 1000 (Rev D)
DOCR-070733-D Page 17 of 86
Use M10 or 7/16 in. bolts to attach the mounting bracket to the mounting surface. Use 4 bolts corresponding to
the holes shown in Figure 3-4. In the background, the inverter is visible in gray for alignment purposes. The top
of the mounting bracket is 19.7 in (502 mm) below the top of the inverter. Torque the bolts as necessary to
support the weight, depending on the material of the mounting surface.
Figure 3-4 Mounting Bracket

Installation and Operation Guide SOLECTRIA XGI 1000 (Rev D)

Place the Wiring Box onto the Mounting Bracket and use 2 of the M6 bolts to attach them. The holes are located
on the sides of the Wiring Box and Mounting Bracket, as shown in Figure 3-5. Torque the connections to 40 in-
lbs. (4.5 N-m).
Figure 3-5 M6 Connecting Bolt (Right Side Shown)
Install the remaining M6 bolt to the bottom of the Wiring Box for the Auxiliary Equipment Grounding Connection
as shown in Figure 3-6.

Lifting Heavy Object Hazard
Proper lifting technique must be used in order to avoid injuries.
Use a two-man lift to install the Power Head.
Place the Power Head on top of the Wiring Box. Position the Power Head so that it aligns with the Wiring Box.
The Power Head will slide into place, using the metal guide pins to align with the Wiring Box. Use the four M5
bolts to connect the Power Head to the Wiring Box as shown in Figure 3-7. Use two screws on the left side and
the other two screws on the right side. Torque the connections to 20 in-lbs. (2.3 N-m).
Figure 3-7 M5 Connecting Bolts (Right Side Shown)
3.3 Wiring
Tools Needed for AC and DC Connections
3/16 in or 4.75mm slot torque driver (AC Connections)
#2 Phillips-head torque driver (DC + and –Connections)
Multimeter (AC and DC Connections)
Power Connections
Use 90°C minimum rated conductors. Connections are rated for both 75°C and 90°C terminal temperatures.
With longer wire runs, the use of larger conductors than those required by Code can help minimize voltage
drop.
