Dear Haseeb, I've been trashing my electronics learning these past 20 years by not keeping up with it. But I stumbled on your channel and found it most interesting to refresh and learn at the same time theoretical and practical knowledge that I can apply to repair or design useful circuits. Thank you for sharing your expertise with us, in clear spoken explaination without distracting background music. I also appreciate how you respond to your viewer requests. My respects goes to you and your family sir for you're a true philantrope. God bless!
indeed your valuable words are a great asset for me. actually it is a precious return for my efforts. please accept my best regards and special thanks Your brother Muhammad Ashraf
So many thanks for this video. Very very informative. You explained in very simple words. This video is very very useful to many Technicians who are in inverter and ups repairing field. Volume is very low please increase. So many thanks again 🙏🙏🙏
Dear Haseeb, First of all I would like to thank you for your detailed and informative explanations in your videos. I would like to ask you the following question: I need to lower the low battery voltage protection from 10.8V to 9V. If I change the current sensor power resistor will this do the job? What value should this resistor be?
Another informative great share. Though I don't understand much about technology but always like to learn how to speak nicely from you. Thanks for sharing brother
Bravo!! I am following you for so long and waited patiently for the DC - DC conversion and then into AC to be explained by a Pro like you . Thanx in advance
Thanks for educating. Great work. I think the step-up transformer's (Booster) output doesn't require a rectifier. Since the output is DC. I suppose it to be a capacitor for filtering. Correct me if I am wrong, please.
Interesting. Can you explain why a transformer is not required on the output switch section on the next video and how it will reduce to 50 or 60Hz. Thank you for the work being made for educating people. Keep it up
Sir, I want to ask you something. The signal at the output here is in the form of a square wave, but what kind of circuit is there to convert it to a normal sinus? thank you
The protection diodes on the PCB are after fuse, that makes much sense. If you connect the wrong polarity, diodes will draw much current and blow the fuses. I doubt this device could handle 3kVA, I would expect max. 300VA perhaps. Would be interesting to test the maximum power possible for some hours. 😊
you are right. it is just a block diagram. so i placed the diode to just give an idea about its importance. i will go in detail as much i can in upcoming parts. as 3000va is mentioned on the cover, we will check its all parameters
it is just a block diagram. i demonstrated diode importance. its detailed circuit we will continue in upcoming parts best regards for your valuable point
Good video, I have a dc motor driver which trips elcb( earth leakage) when I connect the motor to the driver. The motor is brand new and never used, was replaced from failure in the past. I have check the voltage with no load and I measured it be corect voltage values. The pot is also varying the voltage however, when I connect the motor , tripping occurs. Checked the motoe reisistance, and it is measured to 40ohms.
Assalam o alaikum Sir 3000VA inverter men Ac side MOSFET p ik bari wattage Resistor k sath ik Variable Resistor hai us Variable Resistor ko move krne se circuit p ka effect hota hai men Variable Resistor ka function kya hai... Please reply me Fast ...
Salem Haseeb. Tabara Allah in your works and Hope qu'allah help you and promise you a heaven. I have one question about solar inverters . How they car inject power in grid and stop when there is no incoming electricity companies ? could you explain this Chokran zajila. I would like to understand the circuit différence between off grid and on grid. Actually I am using micro Inverters In grid. Thanks a lot. Omar From Morocco.
Aslm alkm wr wb Good morning sir. I will like to become an expert in solar energy installation and inverter repairing services! I follow most of your videos especially on inverter series and they're very helpful. But i don't understand some of the logics. I do local solar energy installation, and simple inverter repair... Now i want upgrade my experience to become a better person. How do i achieve my ambition sir?
Dear brother, Thanks for your valuable efforts for making such a knowledge full video. I am one of your subscriber from long time and watching almost all of your videos. I need bit technical advice on a issue which I am facing in a circuit... I have connected BTA16 triac Which is used to control output voltage UpTo 48v. Input voltage is 220v AC...with normal wapda line there is no issue and it's work very well but once it run over UPS then the output voltage goes up to 70+ volts....please guide me what to do when using UPS supply...or how I can fix the output voltage in any condition of inputs... Regards
Very good friend, your video I am looking for information on how the ups of your power source work, how the low power area works with the high power area, can you provide a video?
Great video! I wonder if you can do a video on checking the operating frequency of an unknown transformer with a signal generator. I tried this once with a Wavetek model 112 signal generator puttting about 13 volts (approximately) into a secondary and used a neon bulb on the primary and it lit up at several frequencies, but no way to measure the greatest voltage point, which I can assume is the designed frequency, even an analog meter gets weird at such high frequencies. It's just for fun, nothing I have to fix. Thank you sir and have a nice weekend!
Assalamualaikum sir. Thanks for nice presentation. I want to know about each component engineering(not the basic) used in this video. I would be glad sir if you show me the way.
2 primary windings are used in prallel to switch more current and reduce core size and reduce primary side losses (in case of using single core) series secondary windings are used to reduce voltage stress during voltage boost action

Correct me if I am wrong, please.
It is closer to dc but it have negative spikes
Which needs rectifier
Very good explanation for the inverter circuit thanks for your efforts gad pless you dear mohammad
Very well explained cleared all doubts.Same principle works in high end solar inverters.
thanks a lot dear
Thank you very much. I love this video. But I don’t understand that why does the push pull stage not have output choke?
as its output is not sine wave. it is just pulsating square square wave (above and below the zero line)
Waalikomaslam bhi
Very informative and useful video
I have learned so much from your channel. You are an excellent teacher. THANK YOU !
انته أستاذ رائع ومحترم اشكرك اخي الكريم على هذا الموضوع الجميل
Salam M Haseeb, would it be difficult to turn it into PURE sinewave ?

Thank you for an excellent explanation of inverter circuit. what kind of MCU is used to check i/o VI and temperature?
Walkum aslam mashaAllah excellent work bhai
Hello friend, I have a similar inverter but is 110V output.
Can haking the output to 220v?
Wonderful video dear brother!!!

very good video. keep up the good work, sir!
Its very interesting topic...new friend.
Shouldn't the protection diode be after the fuse so it blows the fuse when it's short?
it is just a block diagram. i demonstrated diode importance. its detailed circuit we will continue in upcoming parts

Sir mera pass 335w 62 cell ka 6 penel hai aur battery ki b zaroorat nahi.....
Aur load b bilkul Kam hai mujhe kon sa inverter sahi rahiga
Ac
Transformers is not used in DC supply?
Yes
Transformers deal with varying current
Sir here the transformers are paralleled ?
in this configuration the primary side is parallel and secondary sides in series
i will explain it in detail in upcoming video
Thank u sir.
Hi is it work how ups work?
waiting for your pi filter calculation. I hope that video will come soon.....

Assalam walaikum, make more solar power inverter repaire videos
why they use two transformer? why not one transformer? input coils are parallel switching but the output of the transformers coil in series. why?
2 primary windings are used in prallel to switch more current and reduce core size and reduce primary side losses (in case of using single core)
series secondary windings are used to reduce voltage stress during voltage boost action
i will try my best to explain it
