Hardware:

    -Microcontroller
    -Signal conversion circuit
    -Under voltage switch over circuit
    -Battery charger circuit
    -Input voltage/power circuit
    -Current clamps
    -Voltage transformers
    -LCD displays
    -Enclosure

Microcontroller: Arduino YÚN

    -General Methodology
            Timer
            Functions continually check time and compare it to their task period
                        Benefits: not using a lot of processing power for less important tasks (updating LCDs)
    -Limitations
            Limited I/O on microcontroller
    -Overcoming Limitations
            Using I2C communication for LCDs
                        Add module to LCD to give them different addresses
                        Cuts down the number of I/O required for the four LCDs from 9 to 2
