There's a thread here on the forum where I got this link.
I pulled some of the python code, modified as needed, and now I can get data from the sol-ark 12k via rs-485. A script runs every minute to pull data and make charts. You could pull the data much faster than on a 1 minute interval.
For someone not familiar with python, I would suggest the solar assistant product.
