Page 3: Introduction
Modbus Map SOLECTRIA XGI 1500 (Rev A) Introduction This manual explains the SunSpec protocol using Modbus for SOLECTRIA XGI 1000 inverters. This does not include the history of either SunSpec or Modbus or the details regarding the creation of the protocols. It is expected that the person(s) reading this manual have a clear understanding of both SunSpec and Modbus. -
Page 4: Modbus Overview
Modbus Map SOLECTRIA XGI 1500 (Rev A) Modbus Overview Registers can be read using Modbus function code three (3) and certain registers can be written with Modbus function code six (6). When reading or writing to a group of registers, such as reading a string, make sure that the read command starts at the lowest address of the group and is of the appropriate length size for the group. -
Page 5: Power Limiting
Modbus Map SOLECTRIA XGI 1500 (Rev A) Power Limiting This feature allows the inverter to reduce the output from what it could produce given available resources. Power limiting request typically occurs because of transmission congestion or lack of transmission access. It can also occur due to excess generation during low load periods. - Page 6 Modbus Map SOLECTRIA XGI 1500 (Rev A) Click Save button to apply the settings to local inverter The alternative method is to use software which supports Modbus TCP/IP. The register address is shown below. To implement the same setting, the procedure is shown below. ...

Page 7: Power Factor Control
Modbus Map SOLECTRIA XGI 1500 (Rev A) Power Factor Control This feature allows inverter to control the power factor at the point of common coupling (PCC). This can maintain the power quality and stability of the overall electrical system. A power factor adjustment gives the utility greater flexibility to supply the power quality required by the loads. - Page 8 Modbus Map SOLECTRIA XGI 1500 (Rev A) Write “ +0.8 ” to Power Factor Click the little box on the top left corner of the configuration window to enable Power Factor Click Save button to apply the setting to local inverter The alternative method is to use software which supports Modbus TCP/IP.

Page 17: Frequency-Watt Control
Modbus Map SOLECTRIA XGI 1500 (Rev A) Frequency-Watt Control This function helps to change inverter active power output with fluctuations in grid frequency. This will provide frequency support to the electric grid. As frequency increases, the desired response of the inverter is to decrease active power output. - Page 18 Modbus Map SOLECTRIA XGI 1500 (Rev A) Write “ 4 ” to FW Points Active Write “ 60.30 ” to Frequency Write “ 100.0 ” to % Max Power Write “ 60.80 ” to Frequency Write “ 90.0 ” to % Max Power ...
