These posts just proves to me that our schools are failing us.
You know, you don’t have to like or even use the practical “this works” approach for yourself. But your superior air and insulting demeanor is offensive and uncalled for. Some people don’t care if they leave 3.647 watts on the table or even give a flying rip about the math. Or even 100W on the table if what they do or did works.
Nobody’s saying mppt isn’t “better” but some like myself hold to the idea that if in practice it’s enough - it doesn’t matter.
LOL...what does that even mean?
It seems like you want be a jackwagon.
Maybe you don’t. No way to say. But…
These posts just proves to me that our schools are failing us.
No. This just proves you’re not reading the posts, a), and b) you are coming across as a controlling rigid personality with a black/white interpretation of life that isn’t tolerant of other people because you think they’re inferior so you just can’t help yourself but post stuff like that.
The max current a PWM controller puts out is the Impp of the panel. Why is that so difficult for you to understand?
“
Why is that so difficult for you to understand?”
We understand it but in our contexts we don’t care and most people are generally averse to people looking down their noses at them.
our products was the back up power hardware for cellular base stations.
Great.
Running driveway lights or small short-term loads (like my original system that only needed to power my shower and coffeemaker every day) can be done with more flexible criteria. And accept pwm.
With all your engineering background and sophisticated knowledge perhaps you could consider providing helpful input to folks with technical questions that they don’t have the knowledge to solve on their own rather than make fun of people whose practical approaches don’t meet your criteria for a scientifically developed spec sheet of performance carried to three decimal places. Some people with small systems can do fine with a $200 (now $260) “kit” that includes a pwm.
Whether that setup would work for you isn’t usually even relevant.
People do things for fun, or to meet a particular desire or need, a myriad of reasons, and sometimes they have a critical need where budget or fixed dollars are in play.
I suggest thinking about your approach to other people’s problems and whether your input is a blessing or benefit to the recipients of your posts. Mere facts or even substantiated opinions aren’t always beneficial when you consider the vast variety of circumstances people might be in, or what difficulties or challenges may have brought them to this day and situation.
I’m pretty docile in most circumstances but people who pop in to be a jerk for free to myself or anybody else get me fired up. It sounds like you have a lot of experience so you should have substantial information to benefit beginners and non-technical people trying to Diy whatever systems they are attempting to complete. You can choose basically only four routes in life: a leach/dependent, a blessing, a curse, or a bystander. Only one benefits society and some bystanders are medically or mentally impaired so they should get a pass.
