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...

Hi,
I use MPPT and the input voltage to the controller is 33.
With 24 volts, MPPT would be more desireable than PWM. However, some PWM controllers may not be damaged by 24 volts input. Others may let out the magic blue smoke. Read the manual carefully.
A 24 volt panel with PWM will "waste" a lot of watts. The approximate loss amounts to over 25% of the harvest.

I may have missed it somewhere reading through this thread. Blame it to being O&S.
Anyone have hands on, charging 12v batts, using MPPT or PWM controllars with 24v panel?
I will try soon but would like someone to perhaps chime in and say, yes, NO problems.
