Microcontroller based DC energy logger for off-grid PV system application

This paper presents the development of a microcontroller-based DC energy power logger using the low-cost ATmega328 microcontroller to measure the PV system DC voltage and current, while at the same time logging the measured data over time to calculate the generated energy in kWh. An existing 1 kWp o...
