Very interesting, but I didn't agree with you saying it would be boring to show us you actually installing the thing. That's what I am doing recently at work: installing stuff. Thanks for the content though
Love your vids, thanks for the great work!
Great work! Keep it up!

Can you create a series on Electronics ( Especially Micro controllers)
I have some upcoming projects in mind that involve electronics/mcus, I'll try to go into more detail on the design/working of the electronics for those.
@@AKIOTV thank you 😊
Thanks for this. But, can you help me out with a bit more info? I was trying to find out what a MPPT was and I discovered your other excellent video explaining it. From that I got the impression that an MPPT would be varying the voltage and current around all over the place in pursuit of maximum power. Whereas this solar charge controller is operating on the goal of achieving 18v solar panel output, in other words it's been told where the MPP is. Are you just explaining the same thing in two different ways? Or does a true MPPT have extra hardware/software? Also, when you read my question bear in mind a few things; I am interested in electronics but I have no background in it, I use the excellent teachers of CZcams, like yourself. If it is at all possible for me to misunderstand an explanation, I seem to do this effortlessly. And lastly, I'm not trying to be a dick.
You've actually understood it quite well!
"real" mppt is indeed a controller that varies the voltage and current "all over the place" in persuit of maximum power.
My controller in this video is sort of cheating, because I configured the correct voltage for this solar panel in advance, which simplifies the design a bit.
If you added a shunt resistor to the input, the arduino could measure the current (therefore compute the power) and do "proper" mppt.
@@AKIOTV Thanks for your reply, that does clarify things for me. The MPPT is happy to do the work in finding sweet spot of power generation, which will come in handy when the value isn't known, does the value change much between panels? does the panel manufacturer provide the information in the specs? I apologise for the extra questions but I thought i'd roll the dice and see if you are still happy to dispense info. I find YT a fantastic resource and I salute you for you work. U&S
@@dohhomer9 The nominal value will be different depending on the panel, but it's given on the datasheet of the solar panel.
The mpp voltage can vary slightly with light intensity and other conditions such as temperature. For instance, for my panel the optimal voltage may vary between say 17-19V.
My lazy controller design doesn't take this into account, since it only uses one fixed voltage, so using true mppt would result in (slightly) better results.
@@dohhomer9 There are various MPPT algorithms, voltages do vary between panels and within a single panel depending on conditions, you can find real MPPT device and more theory in a video on my channel :) The main point of MPPT is that voltage varies pretty significantly and you need an algorithm to work optimally in all that range, if range were shorter - you could just track fixed input voltage and call it a day.
