If you are only interested in knowing about the solar functioning and accessing 72 days of collected data, then the Tristar has a web server built into it and an ethernet port. You can either connect a computer through ethernet, or connect the Tristar to a router and access all of its functionality and data wirelessly through your computer's browser.
It is easier than it sounds - plug
in the cable, open a browser and there you are. You can have it graph historical data to your heart's content. You can even connect it to the internet
and control it remotely from anywhere in the world.
The Tristar monitor provides all of numerical historical data and shows what is happening in real-time, but you cannot adjust the settings through it.
