Good day; I hope you are doing well .. I don't think so it's two high.. can you do exactly the way the model here is done and than change it according to your values to check the system response
Hello , thank you for your comment, the current is negative due to the following: 1- the current is supplied by PV Solar which is in different polarity when the battery is supplying. 2- In other words, when the battery supplies the current is positive. When it is charging the current is negative because of the different direction of current when it is supplying.
Hello teacher, I hope you are well! Firstly, I would like to congratulate and thank you for the teachings passed on! I would like to know how I obtain this model? thank you for your attention
@@pzengineering2020 Thank you for your quick reply, You won a subscriber. Do you know why the output voltage changes as the simulation time increases significantly?
@@mrmatias2618 Hi, the voltage is affected by the battery SoC. For example When SoC = 100% V = 12.8V , and when SoC is 90% , V = 11.52V. For this reason, during charging the battery voltage will increase up to its rated voltage
@@pzengineering2020 Thanks for your reply, last question please, is it normal the charging voltage exceeds 12.8 V? When the simulation time is increased to 1000 seconds the charging voltage becomes higher than 35 V.
@@mrmatias2618 in case if a battery voltage = 12.8 V; you should put your bus voltage or charging voltage to 13V. During simulation, when the voltage of the battery reaches 12.8 V the charging current becomes 0 A, even if you run simulation 4000000000 seconds, the charging voltage will still be 13 V and battery voltage 12.8 V
Hello sir, thank you for this channel a loot,i have just one question what is the name of the MPPT algorithm used in this video?
I am using 12v battery 7aH battery. Is the capacitance value too high?
Good day; I hope you are doing well .. I don't think so it's two high.. can you do exactly the way the model here is done and than change it according to your values to check the system response
@@pzengineering2020 If I am changing capacitance value to 100uF then current is coming around +50A but the battery is discharging in that case.
Hi, why am I getting 0 current in battery output?
Is the state of Charge higher or the voltage? I think you should check your parameters
@@pzengineering2020 Yes, state of charge is 45 and battery voltage is 12 V
Hello sir its informative video but I have one query
why is current is negative while charging?
Hello , thank you for your comment, the current is negative due to the following: 1- the current is supplied by PV Solar which is in different polarity when the battery is supplying.
2- In other words, when the battery supplies the current is positive. When it is charging the current is negative because of the different direction of current when it is supplying.
@@pzengineering2020 oook Thanks sir
You are welcome
why the charge of battery is constant even connect to the solar ??
Thank you for this video. Is it possible to share the model?
Hello - why do you use Discrete in Powergui vs continuous?
Hi thank you for your comment, It depend on what you want to achieve, type of components and how fast is the simulation
Sir i want this file as a simulink matlab @pzengineering2020
Hello teacher, I hope you are well! Firstly, I would like to congratulate and thank you for the teachings passed on! I would like to know how I obtain this model? thank you for your attention
Hi Caio, thank you for your comment. We will email to you
Why MATLAB dont let me put the battery in parallel with the capacitor
Hi. can i have your charge controller mppt coding for my research. thanks
Also my solar panel I_PV is coming constant 0ish value.
Means there's something wrong you are doing ... the powergui
hi sir can you please share this file
it will be really helpful
Hello, thank you for your comment. We as team we will discuss and get back to u
Why every video, I have been watching nobody is explaining how the code works.
Hi thank you for your comment, the code is for you to follow and change based on your data

Can we please have code
hello, thank you for your comment, we will make it available soon
Is this available now ???
