mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

Hi Salvo,
I'd love to see an analysis of Mppt vs Pwm at a vmp of 33 with a panel temperature of 75C. To make it a level playing field use 16.5 v for the pwm.
i.e. MPPT configuration series/parallel @ 33 vmp
and PWM configuration parallel @ 16.5 vmp.

Fig 14 pretty much sums up the differences. The RV crowd are for the most part fair weather campers. That means cell temperature is in the range 40 to 80C. In that range, for the most part, mppt gains are between 0 and 10% better than pwm. On average it could be about 5%. Nothing to crow about.
