Data Logging
The inverter stores data values and software metrics for debugging. These
values are stored within the CCU2 controller board in non-volatile memory. Data
logging requires the use of a PC connection using the Xantrex Solar Graphic
User Interface (GUI) software.
• The Data Logging features include:
• Operational Values
• Internal Metrics
• Data Log Acquisition
• Graphic Data Analysis
• Fault Log Acquisition
• Software Upgrade
• Accumulated Values
• Configurable Parameters
PC Connection Methods
Personal computers can be used to access the system status and programming
features of the Xantrex GT250 E. This allows monitoring and control of the inverter
from a remote office, a home office, motel room, or any location where a laptop or
desktop computer can make a modem telephone call. Computers can be
connected either directly or remotely. Software is included to provide a graphic
user interface that relates important system information. This software is called
Xantrex Solar Graphic Interface (GUI). See "Computer Communications with the
Xantrex GT250 E" in the Xantrex GT250 E 250 kW Grid-Tied Photovoltaic Inverter
Operation and Maintenance Manual (Part #: 152937) for additional information.
The Enclosure comes with a factory-installed MultiTech
®
56K modem and Surge
Arrestor (-F36). The RS232/Fiber optic converter is configured for ethernet use. If
you are planning on using this connection for direct PC access, it will be
necessary to replace the RS232/FO converter (Part #: 1-152059-03) with RS232/
FO converter (Manufacturer p/n: 1-152624-01 KIT, COMM, DIRECT, PC TO CCU).
The GUI can dial up the inverter and receive fault report calls from it through a
standard Hayes-compatible, landline modem. When the GUI initiates a call
through the modem at the GUI computer, the inverter’s modem answers the call
and initiates a 9600 baud serial connection, effectively as if the GUI was
connected directly. Or, if the inverter experiences a fault, it will initiate a call to the
GUI and report the fault details.
