I am having difficulty in setting up the ADS1015 ESP32 IO PIN config for volts watts gauge switch etc can you please confirm the pins used so I can setup Blynk please
Can u tell me.. At night.. When solar power is not available... The 90v to 12v buck converter is activated via 12v battery... Which is not enough to produce 12v at output.. Because this buck converter input is only 12v and as battery decreases.. the output voltage of this buck converter is further reduced.. At this time.. Ir2104 vcc pin is not getting 12v...its only 8v on vcc pin of 2104 ic... Can it causes mosfet switching problem or any other problems..?? Thank you...
Greetings to you. I have already built it, but I have a problem with the thermal sensor. I used PT100. It shows strange values. What thermal sensor should I use?
May I ask the Mosfet transistors you spec are 290N08 these are serious power 290Amp 80V can I use N channel type IRFP260 these are 50AMP 200V many thanks
Sorry to ask a silly question but in your youtube video there are two main electrolytic capacitors one I can see a value of 1000uf 63 volts, however in your circuit board design they are both 470uf will this charge controller accept input of up to 120 volts @ 30 amps input and provide 12 volts 24 volts 36 volts 48 volts out and calculate best current out or how does this work.And will these capacitor values have to change depending what output or input required if that makes sense sorry for the long question.And thanks for this by the way
Good day. Pave now I'm buying components. I already have almost everything, but what kind of mosfet 190n03 is this. I can't find anything after marking. Video time 2:47.
Are you going to make this available for others to build, I have no electronics education, but I like soldering pcbs, and am in need of charge controllers, I have a 12v small system, for lights and backup inverter, and larger 24v system, with 1200w, and 2700 watt panel arrays, if I could get mppt control of charging by building it, that would be great, I have 8 strings, and basically each needs a controller, or I need a larger amperage output controller, a 120-150amp controller would be awesome, would it be possible to upgrade the output stage to buck, approx. 60v-80v to 24v- 30v with enough MOSFETs to pass 200-250 amps, at 70v Incase I want to move to 48v, (this is what I need to do, to get by with only 2-3 60a controllers) I have 2x 30a controllers and 2x 60a controllers,but need more to get all the panels wired up, I have LiFePo 12v battery, and 7s liion (nmc) for the large bank in excess of 1000ah at 25v, and going to add more, or save to go to lifepo4, you are a genius, I wish I had the encouragement, the opportunity, or even had a better school experience, I wish I learned more about this years ago!

Friend if i want to increase the PV voltage to 150v can i equally change R15 and if i want to increase Battery voltage to say 48v can i equally increase R17 and to what values of R15 and R17 should i use? Sorry for disturbing you.
Nice Mppt. Nice board PCB too. You could have made for all THT components. It will make beginners to build quickly. Thanks for this project. Can one use it for input of say max 150v?
Hello everyone. Just today I modified this mttp to 120 v. Successfully! Modification of the sleeper in the replacement of components. Mosfet Q3 and Q4 290N08 must be replaced with IRFP4668. Capacitor C3 470uF at 200V. Resitor R15 value increased to 200K. Arduino goes line inVoltageDivRatio = 40.2156, // Input voltage divider factor (200+5.1)/5.1. The voltage is must not increase because it is limited Buck Stabilizer 120V to 12v. That's enough for me. Enjoy it.
