This module of mppt inverter is designed for soft switching so for those wondering why two transformer the second one is ahh current control for current spikes to stop igbt from cross conditions when in first and second cycle
My 10.2 PowMr will harvest so Load is being met but battery is not being charge till about 1800 w. The PV input readout is an arbitrary .5 kw till about 1800 w PV input. No one has had a clue why so far. A replacement 6.2 kW PowMr works perfectly. So the issue is surely in the 10.2 unit. Issue existed at initial startup.
hello good morning sir I saw your work through UA-cam, it is very appreciated I have 3kw REVO II ongrid hybrid inverter battery charging problem not turning off blinking continues but when i measure with clamp meter it is showing 4Am current on inverter show 30Am about this issue please help me
Also problem here with smh 3k. It does not charge battery from pv. No error code., no internal damage. Everything else works okay only problem is not charge from solar.. Any help is welcome
Hello sir, can you please confirm the big resistor value of 0.015ohm near the offline psu and the voltage detector ic part number on the back? I am detecting a short after the 5v regulator and the "voltage detector" gets hot. I might have to replace them both. Thank you for your videos
Sir I am having some challenges on my converter and this is the problem the battery out put is OK displaying 13.5V but when if you from the AC side the is no voltage on the output for the AC, what do u pls think might be the problem
@@boatengnketia1114 if the inverter does not display any error, maybe its just some kind of blown fuse or disconnected wire. Check for output voltage directly on the board passed the output terminals
hello o a 3kva 24v hybrid inverter I exploded 2 mosfets in the 220 circuit in the output I changed 4 mosfets but it still gives me error 06 connecting the 220 works normal it gives me 220 output but connecting only the 24v it doesn't exchange 220 ???????? I don't notice any burns or blackened circuits
Hello sir please I need your help I have mast solar inverter 5kva 48v and it's not working because there is a fault code 53 I have replaced all the igbt and the most fest but still same thing please I need your help hope to hear from you soon
very nice and detailed repair. Maybe next time, you can feature DALY bms repairs also, :)
I really admire your good work...

Heya nice repair 1st time seeing you use 2 caps in parrallel to replace 1 cap that reall DIY lol
Sir, every time you post a video, we look forward to seeing your video, sir can you make a growatt off grid inverter repair videos ..

Can you tell me what the cause of the damage is?

Fetts looking okay, no short. Lcd says pv 31 volts. No support from seller.. Inverter is new
Good work sir thank you
Very nice 👍
Good time of the day, my problem is that the Uc3843 PWM does not start, I changed everything else to PWM +7.5v
thank you dear friend

What is the root cause of this problem?
AC input volt surge?
Mismatch battery amps?
Bad design??
Hello dear friend
...
May be :weak battery
..
Or ac input fault
..
Nice

@@boatengnketia1114 does the inverter turn on?
@fabiuh991 yes it do turn on and displays the voltage of the battery, but does not display the input a d the output voltage

sir i having one inverter ,it's not going to bypass on AC mode and it's not charging also.sir can you help me.
Does anyone know of a place to send a hybrid inverter for repairs?
can I ask you some question? Lighitng strike can casue inverter not working?
ofcourse
It cases inverter damaged
