"Because a battery is not totally efficient at converting electrical energy into chemical energy and vice-versa, re-charging a 100Ah battery requires about 120Ah to be put back into it, and this can be achieved by either
120 Amp-hours / 10 hours = 12 Amps for 10 hours
120 Amp-hours / 15 hours = 8 Amps for 15 hours
120 Amp-hours / 24 hours = 5 Amps for 24 hours etc."

As I understand it, a PWM controller can’t handle the voltages of panels in series whereas the MPPT controller can besides the other benefits it provides for larger and more complex systems.
