Humm at 9:05 the voltage is 19.2, current 1.01A, this should be 19.4 Watts. But the display says 9.89 Watts? And how come so much power is consumed if the load is not even yet connected?
This schematics have serious problems. There missing some important things, like the current backflow protection from the battery. U can find this schematics on many videos. so who has stolen them from who?
MPPT finds the sweat spot where the resulting power output is highest. Right before the voltage drops to much it will limit current so the voltage doesn't drop and output power is maximum. MPPT, Maximum Power Point Tracking.
@HowtoElectronics Hi I'm doing the same project but i using a 600W solar panel so i want to ask how can i choose resistors for voltage divider. should i use big resistor ?
@@HowtoElectronics I'm using solar panel voltage range 36.9-73.8 V . I'm charging four 12V/100ah batteries. I will connect them In series to make 48V 100Ah battery bank
Resistors might not help in the case i guess because current will be high. In case you are still willing to use Resistors voltage divider network the go for higher watt resistor with resistance value in terms of mega-ohms. Use proper resistor value for calculation of voltage. Make sure the supplied voltage to adc pin is not higher than 5.
@@HowtoElectronics the PV current is 8.13 A and PV Voltage is 36.9V, PV Power is 300W. so i will connect two of this solar panels in series so that i charge this batteries in 8hours. I get what you are saying but I'm little bit confused on how to rate especially resistors. So my question is my resistor be rated with 600W power or ..?
thanks bro for the good job here. but after looking true the hole work and simulation I found out that the PWM pin used was wrong. that is why it was not working on simulation through proteus. Hence I changed the PWM pin and it stated working but u have to change it equally in the code. 2 The load program in the code was used upside down, hence you need to interchange the code. Hence the PCB connection wrong. pls look into it and do some correction.
Awesome video! What do you think about the next version of this project: 1. A BOOST Converter (instead of the current Buck) - say to boost 2-3x of these 24V Solar Panel string to 110v (or 230v) MSW? 2. Explain why L1 is 33uH and C4 is 220uF 3. Show how L1 turns should be calculated if we were designing L1 from scratch (including toroid core selection) What do you think?
1. Yes we have some tested ready made circuit to boost the power. But it would be a good option to use the 12V frol battery to fed to inverter and make solar based inverter. 2. For 12V battey input charging voltage is 15 and output voltage is 12V. Output current is 50W/12=4.2A. The switching frequency is 50KHz & duty cycle is almost 80%. For a good design typical value of ripple current is in between 30 to 40 % of load current the calculated value we get is around 33uH. You can refer to buck converter design calculator on internet to find out the inductor value. The equations used for calculation of inductor and capacitor is taken from an article LC Selection Guide for theDC-DC Synchronous Buck Converter on instructables.
@@HowtoElectronics I am searching for a way to boost solar panels voltage from 250vdc(8 panels in series) to around 380-400vdc to feed in to an inverter H-bridge to make 220vac. I have made the inverter based on egs002 module and working great. How to boost while extracting maximum power and keep the voltage between 350-400vdc? Similar to hybrid inverter, I want to avoid using batteries so solar charge controller is not an option
@@HowtoElectronicsI'm looking at something like this built with a boost converter so I can charge 6 lithium cells in series so need a 25V battery to charge from an 18V panel. If there is an easy way to customize this unit, it could me made to suit many applications.
why power is coming as 10w it should be near 20w right?

The website article no longer contains the section for The Project PCB Gerber File & PCB Ordering Online information. Where else can we find it?
How do you redesign for your requirement. Is there any tutorial how. And can I charge LiFePO4 Battery
I couldn't find the gerber file you mentioned in the video .
Can I add batter current sensor to measure the battery current, and please suggest for modify the code to that effect.
does this also work with two bateries and two solar panels
Please what's the simulation software you used for this project
Does the circuit automatically disconnect when fully charged?
Sorry mam, where the Gerber file? i cant find it in the description or in the website
Unable to find the Gerber file kindly help in the description.
Can this be use for solar powered electric vehicle conversion?
Which mppt algorithm is used in it
Probably it´s perturb and observe.
Which MPPT Algorithm is used??
Mam this will give more current than pwm controller as we know voltage decrease current increase..?
MPPT finds the sweat spot where the resulting power output is highest. Right before the voltage drops to much it will limit current so the voltage doesn't drop and output power is maximum. MPPT, Maximum Power Point Tracking.
Need to purchase assembled project hardware with loaded program. What is price ??? Without battery, panel and load. Time : 20:15
And why you have used potential divider to sense voltage than a voltage sensor
Voltage sensor modules are voltage dividers. It's basically the same thing
