This link redirects you to a free, web-based, classical thermodynamics textbook authored by Jonathan Scheffe that relies on property evaluation and computations using Python and associated packages such as Cantera. Content is being regularly updated and work is ongoing. See here for a list of updates. This textbook and source code is hosted on Github at jscheffelab.

Thermodynamics with Python

Jonathan Scheffe is an associate professor at the University of Florida (UF) - link and has taught undergraduate and graduate thermodynamics since 2014, along with radiation heat transfer, undergraduate heat transfer and undergraduate/graduate solar energy utilization. In addition to his teaching interests, Prof. Scheffe has an active research lab focused on solar thermal energy conversion to chemical commodoties, such as H₂ and synthetic fuels.

This link redirects you to real-time measurements of solar energy power production and loads from a 1.58 kW solar PV array coupled with paralleled 2x200AH (25.6V) EG4 LL (v2) and 1x200AH (25.6V) EG4 LifePower4 LiFePO4 batteries - total 600 AH. There are two Victron 100/30 charge controllers, with 120 VAC power delivered a Victron Energy Multiplus-II (3000VA 24-Volt). The Multiplus also acts as a switch and is battery and grid-connected. It is programmed to deliver power from the battery as long as the SOC is >25%. With SOC < 25% the Multiplus switches to grid backup power. The output of the Multiplus is connected to a sub-panel to power household loads.
