I previously built an MPPT charger. It is very strong and durable, but it always works silently. I can not know what mode it is working in ?. Battery voltage, Current. So today I'm going to build a 10A solar battery charger (10A is enough for me, because my PV only has 100W).

[@adewaledipo]

Thanks for your wealth of knowledge. You are doing a great job. How can we modify it to allow more current? I guess the use of acs758, more MOSFETs and a bigger coil

[@adewaledipo]

How do I change it to charge 24v battery

[@PhdHung]

@@adewaledipo Change values in ino files. You will easily see the value of min and max.

[@pinklemon10]

@@PhdHung hey. i changed valued. but #define LVD 11.5 to 23 right? (other min max i changed.)

[@ductuandang634]

Good 👍

[@rafalklepinski7372]

Very impressed with the self-sufficiency. Home-made via drill and home etched boards. Bravo! I too will use the 2004A LCDs, the version 1.3 has I2C built-in but I'm told it's not reliable. I first saw Angelo Casii's MPPT video using an ESP32 so that's the direction I've started on. Well done, and thank you for not replacing the quietness with blasting techno music ;)

[@alanmcrae8594]

Very nice project! And love watching your skillset at work. A nice collection of open source MPPT and PWM diy solar, wind and hydro charge controllers would be of great value to humanity. Especially if designed to be easily self-maintained and not throwaway like commercial systems. Watching your work with great interest...

[@PhdHung]

Yes, thank you very much, I'm glad to hear that.

[@2012SUSE]

Translated by google: Very good job! Thank you for your videos and all the best for you.

[@PhdHung]

Thanks

[@calebemeritus3725]

the design is pretty much ok i even added some code to it to make it more intelligent like keypad to select from 12v to 48v panel.also with the keypad you can set the float voltage and bulk voltage to suit your taste.i switched the code back to work for 16x2 lcd.now the design is very compact and advance it may seem a little bit complex to others but now it more intelligent thanks.God bless you

Hi, Thank you for your work on this project I have just started on building it. I noticed your Inductance Meter, do you have any plans for it as I would be interested in building it too? Once again thank you and keep up the good work.

[@immortalsofar5314]

Damnit! If only you'd uploaded this a month or two ago, before I spent £110 on a 50A MPPT. What components would need to up upgraded/run in parallel to handle 50A? I know, watch this space (subscribed). I'm currently building a battery bank with load balancers, in/out current measurement (for battery AH estimation) and a switchable 36V mode that, once I incorporate a constant current board, should make it useful for welding. I'll send you a link if you're interested and I'll upload a video once I get over our shared camera muteness! It is useful, though. Every time I think I should sit down and narrate my video, I come up with something more productive I could be doing!

Hi. I’m a coder. I’m very good with c++. Used to lecture c++ coding. I could go over your code for you if you’d like....but my preference would be to move it to a esp8266.

Thank you very much, but maybe we have to use ESP32. because ESP8266 has only 1 ADC.

[@RobinCernyMitSuffix]

@@PhdHung Or you use an external SPI/I²C ADC. With that and an TL431, you could have a much better precision (14/16bit ADC, pretty stable referance voltage).
