12v battery/ 12./24v MPPT ~ 24v PV Panel
This question troubles the Old and Slow mind. I have a 24v/120w Cynergy PV panel. I would like to use it for duel purpose. For my 24v e/scooter and my 12v RV, not at the same time. The MPPT states (15...

Exactly. PWM charges at pretty close to Isc for most panels most of the time, especially panels where the Vmpp is above the Vbattery. So watts from the panel are way down when using a 24v nominal panel against a 12 v battery. But it works fine if within the capability of the controller. The Voc will just be high when switching PWM pulses on and off.
