Inverter Placement
The SOLECTRIA XGI 1500 inverter is rated for outdoor use and will operate when exposed to direct sunlight or
rain. To obtain the best performance and insure longevity of the inverter, it is recommended to mount the inverter
out of the direct sunlight.
Inverter Facing Direction
It is recommended to install the inverter facing north to minimize direct sun exposure.
Figure 2-4 Inverter Environment (Left to Right) Direct Sunlight, Shaded, and Rain
Mount the inverter vertically and level to the ground. Do not install the inverter in a pitched/tilted/angled
orientation.

Wiring
Turn the AC Switch to OFF before wiring. The AC switch is located on the right side of the inverter (Figure 2-3.)
Turn AC Switch to OFF
Verify the absence of AC voltage.
Terminations are rated for both 75°C and 90°C rated conductors. Ensure that all connections are in compliance
with NEC ANSI/NFPA 70 and local electrical codes. With longer wire runs, larger conductors than required by
Code are often used to reduce the voltage drop. See Section 3.5 for AC connection specifications and Section
3.8.1 for DC connection specifications.
Keep AC and DC connections in separate conduit. All conduit used for connections must use rain tight or wet
location connectors that comply with UL 514B to maintain the enclosure’s NEMA 4X, Type 3R, IEC IP66 rating.
Conduit holes or other modifications to the enclosure are not permitted anywhere on the enclosure except for
the designated conduit entry area.
3.3.1 Open Inverter Cover
Make sure the disconnect handle is in the off position. Use a flat head screw driver to unfasten the five quarter-
turn latches on the front cover, as shown in Figure 3-6. Lift the bottom of the cover and swing upward. Make
sure both cover supports are engaged, as in Figure 3-7.

XGI 1500-250 Series Inverters
DOCR-071074 (Rev 7, 30 MAY 2023) 17 of 72
When opening the inverter cover, both cover supports must be fully engaged to secure the
cover in the upward position. An unsecured cover could fall down and injure nearby
personnel.
When replacing the cover, all 5 latches must be secured to maintain the enclosure rating.
This prevents water from entering the enclosure that could potentially damage the
equipment. Damage due to water is not covered under warranty.
With the cover removed, the inverter is ready for wiring, as shown in Figure 3-8.

3.3.2 Bottom Conduit Entry
All conduit entries must pass through the designated area in the bottom of the inverter. Be sure to remove all
metal chips from the inverter after drilling to prevent metal chips and other debris from potentially damaging the
inverter.
Conduits entering the inverter often allow condensation to form inside the inverter
enclosure. Use an appropriately rated sealant for these conduits to prevent
condensation. Condensation inside the inverter may cause irreparable damage and is
not covered under warranty.

Transformer Configuration
Grid Mismatch
If the grid does not match the requirements, the inverter will not start and damage may
occur. Check with your local electric utility before selecting a grid standard.
The system must comply with National Electrical Code ANSI/NFPA 70 and with all local
rules and safety regulations before the inverter can be operated.
Yaskawa Solectria Solar’s XGI 1500 three-phase transformerless inverters require AC output connection to a
wye configured service with a solidly grounded neutral (see Figure 3-10). The XGI inverter leaves the factory
with Neutral bonded to Equipment Ground; the Neutral is used by the XGI inverter for AC voltage sensing. Note
that the XGI inverter comes with the necessary parts to isolate the Neutral terminal, when that is desired. It is
not necessary to run a neutral conductor. However, if a neutral conductor is installed in the field between the
service and the XGI inverter, it will not carry current. Therefore, if the installer chooses to run a neutral conductor
between the transformer and the inverter, the size of the neutral conductor may be reduced to the same size as
the EGC, but not smaller than the EGC. Acceptable service configurations are depicted in the figure below.
