7.1 Overview

Morningstar controllers with Ethernet connectivity will serve a basic collection of webpages en-

abling the user to:

view real-time system data•

log historical system data•

modify controller settings•

To access the unit’s served webpage from a computer on the network, open an internet browser

(such as Internet Explorer or Firefox) and enter the factory default IP address of the product. (For

example, the TriStar MPPT has a factory default IP address of 192.168.1.253.)

These served webpages are not customizable in layout or data displayed and only one control-

ler’s data can be viewed per page.

7.2 Port Information

Controllers with web serving capability use the standard HTTP Port 80 for communications. In

addition, Port 502 is used for MODBUS TCP

communication.

certain port to a computer or other device on your private network. In this case, we want to direct

all incoming requests on port 502 to the Morningstar controller.

Optionally, you can also forward port 80 to the controller. By doing so, you will be able to remote-

ly access (from outside you network) web pages served by the unit.
