Please give us the combine circuit diagram where we can easily draw a proper diagram in other design software at single layer pcb design. There are required any libraries function in programming? software.
Your lcd display showing 15.2 v and input 88v but there is no way the voltage will say 15.2v with any load or to bleed down the 88 volt to 15 v so your not tell the full info I know this because I built negative buck converter and the voltage won’t turn down and Lest there is a load of 100 watt is on it to show that display
HOw many amps from morning to evening ? 30 - 40 A ? WHat temps at 30 AMSP are at FETs and caps and toroid ? Ripple at output p-p ? Do U have logging to uSD and WEB server or MQTT to show temps, current, voltages, efficiency ?
Hello, there is a 20amp mppt charge control. Is it efficient to connect 4 50 watt panels in parallel or in series with 44 volts in 2 groups, the system is 12 volts?
Can you make and supply one with details for 12 volt / 24 volt 200 AH bank. A multiple stage buck converter for using 3-4 panels in series for maximum efficiency and higher current for even a 12 volt battery. .
Fake. At least the circuit diagram is. There's no way that 4 Mosfets with 7nF input capacitance and a gate voltage plateau of nearly 5V can be driven with a 47K/10K ohm divider from 28.8V (ie. 5.05V gate drive) switched by an optocoupler @ 31.4kHz! It couldn't even drive the one Mosfet that is all that is needed given that at 40A, 12V ouput, conduction losses would be < .5%. Maybe it could work at a few hundred Hz, but then the inductor would have to be enourmous! Reducing the resistor values drastically wouldn't help - 3.76K/2K could at least switch a single FET but the switching speed would still be so slow that the switching losses would be 100s of Watts! The silly thing about this design is that all it would take would be 2 or 3 dirt cheap bipolar transistors as a Mosfet driver to make it work (if not especially efficiently) if you really can't afford a proper driver chip. But cost doesn't seem to be an issue when he links to the 100uH main inductor costing $45 + $25 shipping!!!! A sensible design would use a much higher switching frequency, say, for example, 200kHz using an SER2915H-472 5.6uH, 0.67mOhms inductor costing $3.39 for one off direct from Coilcraft. The Arduino Nano can create a 200khz PWM, but with a reduced resolution of 1:80 rather than the 1:255 (8 bit) default. However if you did modify this design so it can actually work, if you run it at 56V input, 24V/40A output, the input capacitors would likely explode as their ripple current rating (probably 2 to 3Arms max for each capacitor) would be far exceeded by the 20A total ripple current they would be actually called on to deliver...
this deceitful author doesn’t even give how he made 110uH.... Do you know how to make the correct inductance in this circuit? I have already ordered the boards.... and all the components, spent the money.... Help, give information about inductance??)))
Hi Kiyani I have purchased your PCB and made your charge controller based on the schematic and sketch in your download MPT4.2 but no matter what I cannot make it work can you explain this part of the code ( //if(v) vi = (vo * 10) - vi;) and if if(v) should be remmed out. Is there a later version of your code? Also the pcb has a missing track A2 to U2 and the schematic shows the output going to A4 which I presume should be A2 have I got this right or have I made the situation worse? Regards Graham
Your videos are very good, I'm a follower of your content, I'm a beginner in Arduino but I really want to learn and I'm researching a transfer key with synchronism, with your high knowledge you could make one for us
Could you use a smaller inductor if you increased the switching frequency? I know the arduino is limited in it's PWM frequency, but maybe an external IC could increase the frequency and reduce the cost/size?
@@KiyanisLab and maybe you can also make a digital volt and amp meter with an ads1015 or an ads1115 instead of analog this would be great I have seen in your code that it is only calculated to 20 amp is that correct?
شكراً جزيلاً أستمر أكثر نحتاج منك فيديوهات أكثر بخصوص الآردوينو ومجال المشاريع الحديثة التي تخص الآردوينو وخاصة مشاريع خزانات المياه الذكية وتشغيل الموتور أوتوماتيكياً وقياس المنسوب وتكون بطريقة دقيقة وجيده مع شاشة القراءة الكريستال LCD وشكراً ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Sir, Can you please do a circuit that can handle 80A or if there is any way to convert this circuit to 80A because we have around 11 solars paralleled together so it would be a great help if the circuit can handle 80A. Thank you. God Bless You
Great engineer I suggest to add comment on most program line so that it can be well understood and it will create to u more fans based on the way u explain ur code.
Nice project. Can you please explain this part of arduino code : vo=((vo*0.06)/100); vi=(((vi)*0.6)/80); Where the 0.06 and 0.6 come from ? Does this code follow the any mppt algorithm diagram in particular? Does it follow the typical I-V curve for a solar panel ?
that is a simple math: Input Voltage * Input max Amperage = Input Max Power. So it is 80V * 40A = 3200W Then it depends on your battery, what your max Output power is. e.g. for an 12V Battery it would be 12V * 40A = 480W With an 48V Battery it is much more power. 48V * 40A = 1920W
