3.4.1 Transformer Configurations

Grid Mismatch

Inverter may not start operation.

Check with your local electricity supply company 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.

The inverter must connect to a transformer that has a Wye configuration on the inverter side. The ground terminal must

be connected to the center of the Wye. Connect to the neutral if it is present or use a jumper to connect the ground and

neutral terminals together. Make sure such connection is approved by the local AHJ.

3.5.1 MPPT Zones

Figure 3.7 DC Zones in Individual Mode (Left) and in Parallel Mode with Jumpers (Right)

The DC connections are divided into 4 zones with the positive side on the left and the negative side on the right. Each

zone consists of 4 fuses and a bus on both sides.

To run in individual mode, connect the conductors normally.

To run in parallel mode, connect the conductors and bridge the zones.

If an external combiner box is used, the outputs of the combiner box can connect directly to the buses for the zones.

The conductors should be at least 1000V PV wire. Use copper wire of size 10 to 8 AWG (5.3 to 8.4 mm2) as required to

comply with the NEC and local electrical codes.

Ensure no DC power is flowing into unit. Verify with a multimeter.

Check Polarity of DC Inputs

DC inputs with the wrong polarity may cause damage to inverter.

Check polarity with a multimeter.

Use Correct Fuses

Make sure to size the fuses according to all NEC requirements.

Wire connections as shown below. Torque connections to 25 in*lbs (2.8 N*m) with #2 Phillips head torque driver.

Figure 3.8 DC Connections for Single Zone


DOCR-070733-B of 35

3.5.2 Strings

DC Overload

Exceeding the recommended DC to AC ratio may cause damage to the unit not covered under the warranty.

Size strings according to information in this section.

Each zone has four inputs, each with a positive and negative side. Connect the same number of PV modules to each

string in the same zone. Use the string sizing tool (https://solectria.com/support/string-sizing-tool/) to determine

lengths for the strings in each zone.

For individual mode, strings must be balanced for optimum performance and AC output. When doing DC/AC ratio

sizing, perform calculations at the zone level. Maximum DC/AC oversizing ratio is 1.5 STC conditions of the modules.

Each zone maximum input power is 22.5 kW (XGI 1000-60) and 24.4 kW (XGI 1000-65). Note for any application that

may experience higher than 1000 W per m2 on a regular basis, a smaller DC/AC ratio is recommended. Also, the

combined Isc rating of all strings multiplied by 1.25 must be less than 45A for Individual mode.

If you are running the inverter in parallel mode by bridging the zones, then do the calculations based on the inverter

power level. With maximum DC/AC ratio of 1.5 STC conditions, you can connect up to 90 kW (XGI 1000-60) and 97.5

kW (XGI 1000-65). Note for any application that may experience higher than 1000 W per m2 on a regular basis, a

smaller DC/AC ratio is recommended. Also, the Isc rating of all strings multiplied by 1.25 must be less than 180 A for

parallel mode.

Note all configurations must be below both requirements: DC/AC ratio and Isc.

Zones do not have to match, but the strings within each zone must match.

3.6 Communications Connections 3.6.1 Sample Communications Networks

Connection to the internet is required for the inverter. The modem or gateway must have a direct Ethernet connection

to one inverter. The XGI uses TCP/IP Modbus for all Ethernet connections.

The inverter can be connected to either SolrenView using the Revenue Grade Meter (RGM) or through a 3rd party Data

Acquisition System (DAS) that can connect using Ethernet.

Figure 3.11 Sample Network Configurations with Weather Station and RGM (Left) and DAS (Right)


DOCR-070733-B of 35

3.6.2 Connecting Multiple Inverters

To connect multiple inverters together, set up an Ethernet daisy chain or a star configuration using Ethernet switches.

Any number of inverters can be connected using the Ethernet daisy chain. Use Cat6 cable with max length 328 ft. (100m)

for these connections.

Table 13.5 RGM Connection Pinout

Make the RGM connection using Belden 89841 Multi-Conductor cable or equivalent. The inverter by default acts as the

master and has a software controlled terminating resistor. If the XGI is not the master, disable the resistor.

Always make sure the gateway or modem has a direct Ethernet connection to one inverter.

3.6.5 DAS Connection

Only use DAS that can connect using Ethernet.

To connect a DAS, use an Ethernet connection. For sites with daisy-chained inverters the DAS and the modem or

gateway must be at the ends of the chain, with all the inverters in the middle. For a star configuration of inverters using

Ethernet switches, the DAS should attach to a switch.

Always make sure the gateway or modem has a direct Ethernet connection to one inverter.

3.6.6 Weather Station Connection

Only use weather stations that can connect using Ethernet. The weather station must connect to the modem or

gateway.

6. Operation 6.1.1 Inverter Start-Up

Manual Start-Up: In the User interface, on the inverter page, there is a button that will turn the inverter ON.

Automatic Start-Up: The inverter will start up automatically when the output voltage and power from the PV array meet the required values

and AC grid is normal.

6.1.2 Inverter Shutdown

Manual Shutdown: In the User interface, on the inverter page, there is a button that will turn the inverter OFF.

Automatic Shutdown: The inverter will shut down automatically when the output voltage and power of PV modules are lower than the

required values or AC grid fails.

6.1.3 Operation Modes

System Check

This mode occurs when the user has opted to run a System Test, see Inverter Menu.

Normal Operation

This mode occurs when the inverter is exporting power to the AC grid.

Standby

This mode occurs when the output voltage and power of the PV modules do not meet the inverter specifications.

The inverter will check automatically whether it meets the startup conditions in this mode until it turns back to

normal mode. The inverter will switch from standby mode to fault mode if a malfunction occurs.

Fault

This mode occurs when the inverter is in a fault condition.

6.1.4 Grid-Tied Power Generation

The XGI series inverter has an automatic grid-tied power generation process. It will check whether the AC grid meets the

conditions for grid-tied power generation constantly and test whether the PV array has enough power. When all

conditions are met, the inverter will enter grid-tied power generation mode. While in the grid-tied power generation

mode, the inverter detects the grid at all times, and also keeps the photovoltaic array output in maximum power point

tracking (MPPT) mode. In case of any abnormality, the inverter will enter the non-operational mode immediately. In low

light conditions when the PV power is not sufficient to sustain the inverter operation, the inverter will enter standby

mode. When the voltage and power of the PV array become stable and higher than the required value, the inverter will

attempt to start grid-tied power generation again.


DOCR-070733-B of 35

7. Maintenance and Troubleshooting If an inverter is not running correctly, the Status Panel will show there is an issue. When the inverter is working

normally, the first 3 LEDs are lit (Ready, Network and Communications, and Power) and the last 2 are unlit (Maintenance

and Power Fault).

The User Interface will also when an inverter is not running correctly. When the inverter is working correctly, the landing

page will show a green checkmark next to the inverter.
