DIY Solar PV Monitoring System by Using New Blynk 2.0

[@gep8639]

Excellent work every time

[@debasishdutta9063]

Your words means a lot to me

[@buddhimaamarasinghe9997]

Excellent video and presentation, If possible, show how to do it for 24 v battery as well.Thank you very much for sharing your knowledge.

[@debasishdutta9063]

It is the same for both 12V and 24V battery until and unless the solar panel voltage is below 50V.

[@arfanriaz5344]

Excellent work and presentation, If possible, show how to do it for 0-450 volt. Hats off bro

[@gurur952]

Excellent job bro...

I have discovered a major problem with the circuit boards for this project from PCBWay. It appears that there are more than one version of the design and one of them does not work. In particular, the SCL and SDA connections are not correct, and as a result, the circuit does not work. Specifically, on the boards I received, if you follow the trace from the SCL connection for the OLED display, it connects to the SDA on the ADS1115 (labelled SCL, incorrectly), and then on to the SCL on the XIAO ESP32C (pin D5). This means that although the OLED connection would be OK, the fact that the ADS115 connection is wrong means the circuit does not work. Looking at the ADS1115 pinout, the order should be VCC GND SCL SDA ADDR ALRT A0 A1 A2 A3 The SCL is adjacent to VCC, but in this version of the board, the connection adjacent to VCC is the SDA instead. Of course this may be a version control issue at PCBWay, but when I ordered there was no indication of any variation, and my boards are labeled "DIY SOLAR PV ENERGY METER V2.0" Hopefully this may save others weeks of troubleshooting...

That's great Bro..

2.1 version 🙂 Gerber blynk I want you to come and share your files ❤❤❤ Congratulations on your continued success, you are doing very good work.

[@moondaju]

Elegant work and just what I need for my home solar plant real time monitoring. Is this available as a finished item to procure from you and install at home.

[@PHONGNGUYEN-sj9nx]

don't know if this code can be used for ESP8266?

[@Ataxsan]

Kullanabilirsin !

[@user-ob4ue1fg3r]

ja es funktioniert mit dem ESP8266 NodeMCU 12E

Good work Thanks for sharing

Glad you like it

Hi man, I'm so happy to have found your channel. I was searching for a diy ups for the router. I'm now here to asking you if you can do a video on how to diy a smart plug wifi. Will you ever?

[@MrSlandersen]

Thanks for sharing this amazing DIY project. Ive build everything as you said. Thing is I am getting -50A with no solar input, and -38A and 13.22 volt with solar input. The voltage is correct. But the amps shows a negative value. What did I do wrong?

[@MrSlandersen]

My solarpanel specs: 190W - 5,7A - 44,7V

[@sercero]

@@MrSlandersen There seems to be a problem with the current sensor. You should test it with another load. Also it might need calibration

[@user-hw4he1qx5o]

Can i use INA219 instead of ACS758 current sensor

[@nl6524]

Very nice ❤

[@johncooper5769]

instead of XIAO ESP32 and ACS758 can i use esp32/esp8266 and acs712?

[@user-ix2dy3vg9t]

Looks like resistor values/labels need correcting. Schematic does not match the pictorial diagram on blog site.

[@user-hb2zs6il1r]

Can you make stable on-line ups with LifePo4 batteries? Use relay or other stuff to makes stable ups. No downtime even 4ms.

[@user-ix2dy3vg9t]

Also Arduino code as instructed on blog will not compile at with Arduino IDE or PlatformIO, spent hours troubleshooting and finally used an Arduino AI website to fix multiple errors in the posted code. Then finally came to life. This project needs attention, especially for beginners that are simply following instructions and there are no responses here for issues found. If I had not ordered, waited and assembled all the parts I probably would have just gave up. Unfortunate, as this is a great project - just needs some serious work before posting in my opinion.

[@weekenddiyprojects5072]

Hi, Nice project and thanks for sharing. Need one help. I have tried to make it for my home solar system but it is showing 22amps current without any load. Could you please help me ? Thanks

[@MrSlandersen]

Did you find any solution? Mine is showing -50A without any load.

[@weekenddiyprojects5072]

Yes, I have replaced resiator with 10k trim pot and adjusted values accordingly

[@PavolFilek]

NIce, I need something like this for my DIY MPPT - 100 AMPS, where I can buy boards ? Maybe 20 - 30 ?

[@samjithca786]

Hi.. I made the same project without the temperature sensor and it works fine. But the current value is not stable as it is in your video. It varies very much within milliseconds. How can we stable the reading?.. Also I need to press the reset button every morning to start the program run even if the power is present....Please help...Please help...

[@valtersouzaribeiro761]

muito bom

[@user-ut6hi8tv7i]

I'm in the process of building your monitoring system. Just received the boards from PCBWay yesterday and will start assembly in the next day or so. If I am interpreting the design correctly it appears that the board is powered by connecting the solar panel to the XL7015 which then supplies 5V. It's this correct? But, it is not clear what the function of the battery connection is, what type of battery it should be, and, how it is to be connected to the Xiao ESP32C3. Are you using the backside battery connection of the Xiao ESP32C3? How is this done since you have that chip in a header? Also, if the battery is intended to be an 18650, for example, is there enough space inside the case? Can you perhaps add some explanation either to your blog or you FB page on what the role of the battery is and how it should be used? TIA.

[@ndumisomnomiya5657]

Hi, i hope that you are well. i'm Ndu and i'm in the process of doing the same project. did you managed to win with yours?

[@user-ut6hi8tv7i]

@@ndumisomnomiya5657 Yes, but there are some issues. First, regarding the battery connection, I never connected it. The designer did not respond to my inquiry. He also now has a version 2.1 (with no documented circuit) in which he mentions a "corrected" battery circuit. So it's impossible to know what this means. Also, SEEED indicates that for a battery connection, you must place a diode on the + connection. The problem with not having the battery is that when the solar is off, there is no backup and the circuit does not operate. It must be restarted manually. However, by far the biggest problem is the one mentioned in the next comment: the SDA and SCL connections are wrong. They should be in the order listed in that comment. I was able to get the circuit to work by scratching through one of the connections and using a jumper for the other. It now works perfectly. Finally, I've had some trouble with the unit disconnecting from Blynk. However, I suspect that's a network problem and does not reflect an issue with the design.

thanks for the video .. and the nice project But I have a problem. after 11 Ampers the device starts going wild and unstabile.. one second is 150W and second later is 230 W. the same is voltage. I also have to reset after the night. Does anyone have a similar problem? Thanks in advance
