Communication Features and Methods
The Xantrex GT250 E provides two types of information to the user:
• system status and/or fault information, and
• data logging information.
System status and fault information can be accessed using the Universal Front
Panel Control Unit (UFCU) or a personal computer using the Xantrex Solar
Graphic User Interface (GUI) software. Data logging requires the use of a PC
using the GUI software.
The Xantrex GT250 E communicates system status information to the user using
the following methods.
• The Front Panel Control Unit (UFCU) Display
• PC Connection (Direct and/or Remote) - Xantrex Solar Graphic User
Interface (GUI) Software required (may require additional hardware)
• External Analog Monitoring - (Optional) (e.g., Irradiance, PV temp, ambient
temp, wind speed) (requires additional hardware)
System Status and Fault Reporting
Basic system status and all fault conditions rising from within the Xantrex GT250 E
are reported to the UFCU. The unit stores the time and details of all faults in non-
volatile memory. The 4-line LCD will display a hexadecimal value and a brief text
description of the fault.
The fault value is also made available to the Graphic User Interface (GUI). The
GUI has a more extensive description of the fault.
The UFCU keypad is located on the right center door to manipulate and view
system operation and status. The keypad is comprised of 20 touch-sensitive
keys that provide a means to navigate through the menus and alter user-
changeable settings.
