mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm
Forum Discussion
"But the questions still remain, at what point does mppt become justified, or even necessary, and how much solar is too much?"
When array voltage is FAR above the battery voltage
I do not believe MPPT is justified with a 17Voc array and a 12 Vdc system
Each and every installation is different
Each and every ones wants, needs, desires and finances are different
Some are concerned with long wire runs aka power losses - Some with array shading - Some with keeping the electronics out of sight - Some with keeping the DW happy - Some just like to play with the technology - Some with $$$$$ - Some ......
A proper Buck conversion stage power loss on the systems I've been involved has never been of any concern. Too many other power losses that far exceed the loss from a quality buck conversion stage
"Some say you cannot have too much, but I disagree."
To each their own
