6 EMBEDDED WEB SERVER
6.1
Overview
The interface contains an embedded web server (also known as an HTTP server), which allows users to
access the inverter’s internal data in a graphical manner with web browsers such as Microsoft Internet
Explorer or Mozilla Firefox. In this way, the inverter can be monitored and controlled from across the
room or from across the globe. To access an interface’s embedded web server, directly enter the target
unit’s IP address into the address (URL) field of your web browser. Refer to Figure 16 for a
representative screenshot of the web server interface. In order to access the web server and view the
parameter values, destination TCP ports 80 and 843 must be accessible from the client computer.
Note that in order to view the interface’s web page, the free Adobe Flash Player browser plug-in is
required. The plug-in can be downloaded from

Monitor Tab
6.2.1 Information Window
Figure 17 shows the Information Window that displays messages regarding the status of the interface
card or web browser session. There is also an “ACTIVITY” indicator located in the lower-right hand
corner of the Information Window that blinks periodically to show the status of data communication
between the web browser and the interface card. If you do not observe the activity indicator blink at all
for several seconds or more, it is possible that the web browser may have lost contact to the web server
due to an inverter power cycle or a network problem. To reestablish communications, “refresh” your web
browser.
