Damn i was hoping you could teach me about mppt
Maybe read a thread for context before spouting off wrong information...
Justin had the context down pretty well for not getting all of the threads drivel.
And he summed up perfectly and much more directly than i could have, but i did tell you an 'im not able to fully respond version of what he laid out.
Nobody is capping your creative juices here...... but its kindof an information hub for important topics to people which also have critical safety details to observe and expensive equipments to protect from damage caused by their installation.
So im going to say do not exceed specs.... i do not even know how i got that far into this to look now.... with someone on the other end saying its ridiculous, i should never have answered but for the benifit of not letting it be thought this could be ok unless expressly indicated in the devices intended operating capability and safety allowances under all conditions it could possibly operate in....
Even a total failure or unintended contact of any conductor in the device.
Thats the current rating, its what melts stuff and causes fires.
The pv line has to be able to be shorted in the control at least momentarily to be safe to operate. And the terminals have to be able to maintain shape and tension on the conductors and handle max current or bad stuff is going to happen.
Some pv sources have no overcurrent protection. Which is safe as long as all critical details in the chain of components are capable of handling it.
If im not mistaken, you were roughly saying that someone could put any size pv source up to max output current on a controller and it does not matter because it will only draw the rated controller amps.
For a lower understanding level, you and i can call it paper, rock, scissors.
Justin is a bulldog! Thats funny and appropriate. He nailed me once for vaugely suggesting a fuse be used without its holder! I agree, hes right and its not safe to leave information on here that could too easily be misconstrued to ill effect. We would fascimilate the copper holding tab...... in my secret project, it cannot with conscience be said is fine for someone to do without reservation. Someone was looking for a parts hack type solution and Justin was not having it!
Fun stuff. Which is why it is important to keep the standard up. And im glad for it, even when im wrong. But it takes an understanding of the meaning of communications and.....
In radio we call this QRM or interference. The ansewer to which is to ignore or switch channels if its being done to no good effect on communications.
