With an Arduino Nano and a ESP8266 I am measuring the voltage of my solar system and the environment of the building it is stored in.

Have a 45 W solar panel on the roof connected to an AttoPilot for measuring voltage and current, and powering a bunch of step-down converters to charge a variety of LiPo batteries.
