This project working well with mains power supply. But with solar panel input side current and output side current is same. This is a simple pwm base charge controller.

[@fergal33]

Maybe more like an FPP (Fixed Power Point) rather than MPP converter, as their is no intelligence on the board to vary the output voltage going to to the lightbulbs. MPP would require that the output voltage be variable depending on the solar conditions. in Low light conditions (dusk/dawn/clouds) the bulbs will try to draw power at the output voltage of the converter, but the panels will not be producing sufficient power for the full load and the whole thing will just stall. I've been working on something similar myself, basically controlling a buck converter with an Arduino. It can adjust the output voltage via a motorised potentiometer and continuously adjusts this output voltage in order to maintain the input from the solar panels at a fixed power point (roughly = Vmp of the array). This setup can sense when the input voltage drifts away from an efficient power point for the panels, and correspondingly adjust the output of the converter up or down in order to maintain a fixed input. Hopefully some of that made sense, it's difficult to describe as I'm kind of new to all this stuff. Nice video!

[@PhdHung]

Exactly, This is just a buck circuit.

Pin 5 From UC3845N is connected to the GND Or Goes in Inductor like in schematic??? Is Schematic Wrong??

[@The-Electronic-Engineer]

[@JoshuaAdeoye-u8f]

I downloaded the project and check the circuit. I have some questions 1. The IC does not have any reference to GND, how will it turn on? 2. The mosfet is N-Channel and the source pin is not reference to GND, and it is not bootstrapped as well, how will it turn on? 3. In your circuit diagram, the mosfet is driven with totem-pole network (s8050 and s8550) but in this video, the board you are testing does not have these transistors, why? Please explain

[@lucianungurean]

MPPT should Do both buck and Boost . @61 volt it's just a Buck design . in order to do boost you should do with a supply less than the output voltage . Simulate a real Condition of a MPPT . Get your data from 21V and below 12v if It can maintain 14v at the voltage you got a winner

[@pinklemon10]

What diodes did you use next to the mosfets? 2 pieces?

If i used non-isolated to charge my 23x maxwell super cap it will not work when the super cap has no voltage / empty Thanks

[@arnoldysugondoputra1405]

Hello sir, this good job project. But I want to ask, what if the input of the solar panel is only 18V, what components need to be changed for the MPPT system for charging the 12V battery?

[@JVSVISUAL]

you dont you will need a charge controller after this buck so as to control the on and off charge to the batteries because batteries need to be charge controlled so you do not under charge or drain them or the opposite over charge them. The buck circuit is designed to take various input voltages from 15v -120v to a set output of 12 - 24V but you can not just stick that to a battery or you may cook it.

[@PrincipeMaquiavelo]

Where there is advertising, the truth does not shine

Hello, I enjoyed watching your video. There was something that caught my attention. You solder the S8050 transistors at 3:00, but at 5:51 and after, these transistors are not on the pcb. What is the reason?

[@PhdHung]

I don't see a difference between having the totem pole driver and not. So I removed them.

Shaper during shipping is available from the battery before it. In duration as well. Question how can a balance and dynamic circulation can be designed on the battery so that during shipping is not the full battery before the whole. Thank you brother my cream 🌹
