please i need one conect box for ua65hu9000 reply plz

please can someone write cooler marks on bottom, one of mine is damaged so its noisy. so I can find iz and replace iot. please

Could you please share Schematic Diagram of Low and high Frequency Inverter. I'd like to study in detail. Please.

Thanks boss thanks so much for this

Hello Sir, Yo do a nice Job, I want to know how i can fix error 56 on a Growatt Off Grid Solar Inverter SPF 3000TL LVM, Please.

Thank you very much. Can't wait to see next again.

If you need worker, Pls contact me.☺☺☺

@5:43 If the mppt board shorts with the DC, is there a possibility that the short can damage the inverter board? if yes, how come this inverter board survived the mppt board short circuit?

What is the name of lead sucker and how to buy? Could you please show me the photo of that.

Could you please share How many MOSFET can use for inverter switching function part?

can we use a similar mosfet of different number for the replacement

It seems for this inverter, it still work without the mppt board. Does this apply to all inverters, if their mppt boards are removed completely?

even with the damaged mppt, will the inverter still invert from DC to AC and supply 220v to load?

@54:37 if the mppt board is faulty, will the inverter still generate error 51?

Thx! What I was looking for

Great work

Nice video my dear friend

Heya, very nice vlog love it and thanks for the clear explanation. I have a simalair inverter but then a 5048 made a short on the pv in wen there was 350V on the mppt but can't find any faulty component on the MPPT PCB so I guess the problem is on the mainboard. could you explain the working and setup of the main board and what this squar PCB board for AC does. would like to learn this from you

Thanks Given. Awesome video again. Can't wait for the next one.

Heya, nice repair and nice explanation about the rom inside the microcontroller

good work bro

Hello Bro', I'm watching you from Zambia,great tutorial.Please share where you get all the replacement parts 🙏🏼

hi , at the first thank you for the useful information but i have the same inverter with the same error and really it has been more than moth and i couldent solve it if you can help me i really will be graetful and i will pay if you want i really need to fix it so please help me out

Do you selling spares aswell ?or you do repairs only?

Given you are a extremely expert on your job ,I will highly recommend you to anybody having a problem on there inverters or tv

Heya, very nice vlog love your explanation. just a question could you do a more in dept explanation how the main board is connected, I mean pv in to battery and to load and to grid etc love to unterstand the layout and the current flow even the smps's is there a start up sequence ? thank you very much

Thank you Given, you are brilliant.

Excellent job brother

Where can I buy the one connect cable for this type one connect box, Amazon doesn't have it. Anyone knows where I can buy it from?

Nice job chief

Thanks Given, i have learned something.

I have one question what is the method of download any inverter schematic diagram are service manual

👍👍

Given you are brilliant.

😊👍👍👍

Is infini v2 inverter

How is the quality of those ecco inverter?

MPPT board how much board cost usd?? where to get

So the plastic case was the only thing that was good 😂

Heya, nice replacemant of a bms. but do you have a vlog were you repair that bms that would be nice

Heya, learning from you thanks a lot new sub

Hi it differs with inverters, some inverters will work but some not. eg Growatt will give an alarm when the mppt board is missing if you disconnect mppt the inverter will show high voltage on pv fan will spin at max speed ie it will mulfunction

Assuming the mmpt igbt was faulty, can the inverter still convert DC to AC, if there is problem with the mmpt circuit? or will it affect the whole inverter from functioning if it happens that the mmpt side is faulty?

At 8:52, Customer shorted out the output, which lead to overcurrent situation or shortcircuit situation. I suppose this inverter should have a short circuit protection. Is the over current or shortcircuit protection not able to catch the shortcircuit and turn off the inverter to prevent it from damaging the igbt?

nice work😍🥰🥰🥰😍😍🤩🤩😘

I have been doing inverter repairs for quite a long time now, what I have discovered is that what makes these inverters fail is mostly poor circuit design. i started off when the mainstream inverters were all low frequency transformer based and they would fail also. most of these cheap Voltronic Axpert based or copy inverters use low quality or sub standard components like capacitors, IGBTs, Mosfets, poorly done PCBs etc. check for example high end high frequency inverters such as Goodwe, those ones are robust. i used to work as a repair technician for a local firm that used to import low frequency transformer based inverters from India, to be honest they would fail also. There was a point when the company decided to import UTL and we had problems of their inverters failing each time after the grid is restored back after a power failure. We had to move away from those UTL inverters and started selling the high frequency transformer model Axpert type branded MECER which were the original from Voltronic. we never experienced any problems with these new inverters. Nowaadays the market is flooded with cheap and poor quality inverters and those are the ones that makes it look like the high frequency inverter type are not robust. These new Kodak branded models come with low grade components, poorly designed PCBs etc I agree that the complexity of the high frequency inverters makes them prone to premature failure because the inverter has many sections and if one of those goes faulty, it affects the whole inverter.

Thanks for sharing your experience.

How do you check the MOSFETs while they're still in the board?

Great work
