Electrical System Overview!

•  System requires >99% uptime!•  Solar panel and wind turbine provides power

redundancy with battery backup!•  Primary 12V power rail supplies energy for indication

systems!•  Secondary power rails provide power for microcontroller

(8V) and sensor electronics (5V)!•  Also provides physical interconnections for data

transmission between sensors and user interface!
