The new voltage and current sensors on the battery side mean that Watts in and Watts out can be measured and an efficiency percentage calculated. High efficiency values (96% - 97%) are achievable when the buck converter is stepping down from 18v to 12v. With a 72-cell panel and the converter stepping 35v down to 12v, the efficiency drops to around 88%.
Code for this project is now available on my website:
