Measures voltage & current of each solar panel separately
Measures voltage & current of a (backup) battery
Uses INA219 for measurement
Communicates via I2C
There are two thermally isolated regions on the PCB as the Schottky diodes generate heat. The PCB will be potted in a heat conductive epoxy while keeping the regions isolated. The potted Power Sensor will be attached to aluminum structure that will be cooled down by the surrounding water.
