This is a video that covers the basics of how solar charge controllers work, how PWM units prefer Amp over Volts solar input, while MPPT clearly prefer Volts over Amps. I go over the function of the PWM unit features and the Victron MPPT 100/15. I connect a power supply unit to emulate solar input and see that both units are very close on efficiency which i was surprised to see as i expected the PWM to show bigger losses. The video also demonstrates how the charge controllers distribute power to the battery or loads applied via the load outputs that each unit offers. Both SCC units made use of 5 Mosfets in case you wondered what was inside the units.
It may help those learning about solar the basics of operation. Learn more about off grid solar at dcguy.co.uk
