Goals

  • Research
  • Isolate ADC
  • Interface with the RaceMax meter board connecter pinouts
    • Interface with Nomura MPPT
  • Connect to the STM32F072CBT6 microcontroller

Background and strategic fit

Interfacing with the RaceMax board will allow for solar array diagnostics.

Assumptions

Interface with Nomura MPPT

Multiple Nomura MPPTs connect in series with the array, while before there was just one MPPT connected in parallel with the array. The Nomura MPPT's setup allows for greater power output.

Research must be done on voltage and current sensing.
