Turn AC Switch to OFF

Verify the absence of AC voltage.

Grid Mismatch

If the grid does not match the requirements of the inverter, the inverter will not start.
Check with your local electric utility before selecting a grid profile.
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.

3.4 AC Connection

Turn the AC Switch OFF before wiring. The switch is located on the right side of the wiring box, see Figure 2-3.

Transformer Configurations

The inverter must be connected to a transformer that has a grounded Wye configuration on the inverter side (see
Figure 3-12 for correct configuration and Figure 3-13 for incorrect configuration). The neutral conductor is used
by the inverter for voltage sensing and does not carry current. Therefore, the size of the neutral conductor may
be reduced to the same size (not smaller) as the EGC. Acceptable service configurations are depicted in Figure
3-12.

It is permissible to connect the neutral terminal of the inverter to ground inside the inverter wiring box through
the use of a jumper. In this configuration, no neutral conductor is required. If terminated properly this connection
will not impact the function of the inverter or create an unsafe condition. Ultimate approval of such configuration
lies with the authority having jurisdiction (AHJ).

Figure 3-12 Permitted Transformer Configurations

A jumper between Ground and Neutral may be used if:

 Use of a jumper is approved by the AHJ (required)
 There is no accessible Neutral wire

DOCR-070733-D Page 23 of 86

Installation and Operation Guide SOLECTRIA XGI 1000 (Rev D)

Neutral to Ground Jumper

Do not use a jumper between ground and Neutral if the Neutral conductor is connected.
Using a jumper with the Neutral conductor connected may result in damage and void the
warranty.

Improper Transformer Configuration

Inverter will not run and may have hazardous current.
Connect transformer in specified configurations only (see Figure 3-12)

AC Connection Specifications

The AC connections consist of 3 phases (L1, L2, and L3), ground, and neutral. Conductors must be rated for a
minimum of 600 V. Use conductors in accordance with Table 3-1in addition to local electrical codes.

Table 3-1 AC Connection Specifications

Turn AC Switch OFF before wiring. Wire the AC Connections as shown below. Torque all AC connections
according to Table 3-2 with the 3/16 in (4.75mm) slot torque driver, as shown in Figure 3-14.

Table 3-2 AC Torque Specification

When using aluminum conductors it is important to prepare the conductors properly to prevent oxidation. Follow
the steps below to prepare and landing the wires one wire at a time.

a) Remove the oxidation from the connection area of the aluminum conductors.
b) Immediately apply neutral dielectric grease, such as Noalox, and connect the cable to the terminal.
c) If the connection is not made within 30 seconds of applying the grease, repeat this process as an oxidized

layer may have formed on top of the conductor. This oxidized layer is a poorer conductor than the greased
aluminum.

3.5 DC Connection

MPPT Zones

The SOLECTRIA XGI 1000 inverter is equipped with four separate MPPT zones. Each zone can accommodate
up to four PV strings. All positive conductors must be landed in the fuse holders on the left side of the wiring box;
all negative conductors must be landed on the right side fuse holders. Both positive and negative conductors are
fused. See Figure 3-11 for a detailed layout of the wiring compartment.

The SOLECTRIA XGI 1000 is capable of operating with all MPPT zones tracking independently (Individual
Mode) or in unison (Parallel Mode). Individual Mode provides design flexibility when dealing with different array
orientations, shading, or string sizing. Parallel mode can be used when all strings connected to the inverter are
of similar lengths. In some circumstances parallel mode may allow the designer to maximize the DC/AC ratio.

The SOLECTRIA XGI 1000 wire box must be ordered from the factory pre-configured in either Individual Mode
or Parallel Mode. This is not field configurable. SOLECTRIA XGI 1000 powerheads are field configurable using
the HMI during commissioning.

DC Overload

Exceeding the recommended DC to AC ratio may cause damage to the unit, and will void
the warranty.
Size strings according to information in this section and the applicable codes.

High Irradiance Installations

Note that for any application that may experience higher than 1000 W/m2 on a regular
basis, a smaller DC/AC ratio is recommended

High Irradiance Installations

Note that for any application that may experience higher than 1000 W/m2 on a regular
basis, a smaller DC/AC ratio is recommended

DC/AC Ratio and Current Limits

Both DC/AC ratio and current limits must be observed.
Failure to meet these requirements may result in damage and void the warranty.

String Sizing

Each zone has four inputs, each with a positive and negative side. Connect the same number of PV modules in
each string landed in the same zone. Use the string sizing tool (https://solectria.com/support/string-sizing-tool/)
as a guide to help determine appropriate string lengths. It is the responsibility of the system designer to perform
all string sizing calculations to ensure proper operation and code compliance.

3.5.2.1 Parallel Mode

For factory configured Parallel Mode installations, perform the calculations based on the total inverter nameplate
power rating. With a maximum DC/AC ratio of 1.5 at STC conditions (Equation 3.1), a user can connect up to 90
kW (XGI 1000-60/60 & XGI 1000-60/65), and 97.5 kW (XGI 1000-65/65).

The Maximum Short Circuit Current (Isc rating of all strings multiplied by 1.25) must be less than 180 A for
Parallel Mode (Equation 3.2).

3.5.2.2 Individual Mode

For factory configured Individual Mode. The maximum DC/AC ratio in Individual Mode follows Equation 3.1 on a
per MPPT zone basis. Each zone’s maximum input power is 22.5 kW (XGI 1000-60/60 and XGI 1000-60/65)
and 24.4 kW (XGI 1000-65/65).

The Maximum Circuit Current (combined Isc rating of all strings in the MPPT zone multiplied by 1.25) must be
less than 50A (Equation 3.3).

Unequal String Lengths and Module Mismatch

Unequal string lengths and significant module mismatch can result in the flow of current
between strings connected in parallel. Opening fuses under load can cause a hazardous
condition. It is strongly recommended to avoid unequal string lengths and module
mismatch.

3.5.2.3 String Mismatch

To ensure optimal performance the number of modules per string should be equal within a given MPPT zone
(Individual Mode) or across all zones (Parallel Mode). Individual Mode and Parallel Mode must be specified
when ordering the wiring box.

Ethernet Cat 6 Shielded Cable

It is important to use Cat 6 Shielded cable to ensure communication speeds are
optimized. Solar PV inverters

3.6 Communications Connections

Communications Network

Connection to the Internet is strongly recommended for the SOLECTRIA XGI inverter. An internet connection
will provide the user with several important features including: automatic firmware updates, remote diagnostics,
troubleshooting, and give access for Yaskawa Solectria Solar Technical Support & Service.

The gateway or cellular modem should have a direct Ethernet connection to one inverter in order to benefit from
the remote capabilities inherent to the inverter and to receive remote firmware updates. See Figure 3-20. The
inverter uses Modbus TCP/IP over Ethernet Cat 6 Shielded cable.

Figure 3-20 Connection to the Gateway

The SOLECTRIA XGI 1000 is compatible with SolrenView and third-party Data Acquisition Systems (DAS).
When using SolrenView monitoring no additional hardware is required, every inverter has a built in DAS. Only
Ethernet connections are supported for third-party DASs. Figure 3-21 shows a sample network with a DAS and
a Weather Station.

Installation and Operation Guide SOLECTRIA XGI 1000 (Rev D)

Figure 3-21 Sample Network Configurations with Weather Station and DAS

Connecting Multiple Inverters

To connect multiple inverters together, set up an Ethernet daisy chain (see Figure 3-22), star configuration using
Ethernet switches, or a tree configuration (mixed network) (see Figure 3-23).

 The maximum number of inverters in any single daisy chain is 50 inverters.
 When using star configuration architecture, the maximum number of inverters from one end of a daisy

chain to the end of any other daisy chain must not exceed 50 inverters.

Use a shielded Cat6 cable with max length 328 ft. (100m) for all ethernet connections.

Figure 3-22 SOLECTRA XGI Inverters Connected with Ethernet Daisy Chain

DOCR-070733-D Page 35 of 86

Installation and Operation Guide SOLECTRIA XGI 1000 (Rev D)

In a star configuration, up to 100 inverters can be connected. Mixed networks can support up to 100 inverters
providing none of the individual daisy chains contain more than 50 inverters. If longer distances are required,
fiber optics can be used with an appropriate switch.

Symbol

Explanation

Inverter OK: This indicates that the inverter is on the Reference List and functioning normally.

Inverter Missing: This indicates that the inverter is on the Reference List but is undetected.

Inverter Unknown: This indicates that the inverter detected is not on the Reference List.

Inverter Fault: This indicates that the inverter has an inverter issue and cannot produce power.

Inverter Warning: This indicates that the inverter has an issue but can produce power.

Inverter List

The Inverter List shows a register of all the inverters linked to the same WiFi network to which the laptop or smart
device is connected. These inverters are said to comprise a cluster. Each XGI cluster consists of a maximum of
50 or 100 inverters depending upon connection type, see Section 3.6.2. To access the Inverter List, connect to
the cluster’s WiFi network and then open a browser to “xgi.solar”.

The Inverter List displays the names, serial numbers, IP addresses, and status of the inverters registered to the
cluster. Below is an example Inverter List and a chart that explains the symbols. Note that the inverter in bold is
the inverter to which the user is connected.

The Inverter List is separate from the Reference List, which is managed by the customer. Changes to the
inverters in the cluster will affect the inverters on the Reference List only. See Sections 5.2.3.6 and Figure 5-33
for how to change and setup the Reference List.

To navigate to a particular inverter, select the name of the inverter by clicking it.

Firmware Update

This screen allows a user in administrator mode to update the firmware.
The SOLECTRIA XGI 1000 series inverter supports both local and remote firmware updates. Remote updates

are performed automatically from the Yaskawa Solectria Solar server or by request through our technical support
department by calling (978-683-9700 ext 2). Remote firmware updates require an internet connection.

Local firmware updates must be performed with a laptop and an Ethernet cable.
By default, Enable Automatic Remote Firmware update is selected. The inverter will check for firmware updates

and download automatically if one is available. The firmware will only be downloaded once to the gateway
inverter and then distributed across the rest of the network. On the following morning, all inverters will perform a
self-update. During the self-update the inverters may not produce power. Updates are completed in the early AM
once PV power has stabilized but prior to peak production to reduce lost revenue. The firmware download is a
small file of only incremental bits making its data usage minimal.

Having the Enable Automatic Remote Firmware update unchecked is not recommended as product
improvements may have occurred since the purchase of the product. If the user disables this feature, the Site
Owner will be responsible for performing any firmware updates.

Three fans are user serviceable. All fans are located and accessible on the sides of the inverter. There are two
DC fans accessible on the right side of the inverter underneath the antenna, and one AC fan is accessible on
the left side at the bottom of Power Head. The AC and DC fans are different parts and cannot be interchanged.
To access the fans, remove the screw with a #2 Phillip head screwdriver and press the tabs together to remove
the assembly. See Figure 7-2 to remove the DC Fans and the AC Fan.

Figure 7-2 DC Fans (Left) and AC Fan (Right)

On the top of the fans, there are two arrows at a 90° angle. Fan alignment is based on the arrow that points in
the direction that the fan blows, as shown on the left side in Figure 7-3.
