I run a repair shop and watch your videos and learn alot from this channel. Yesterday a Growatt solar inverter model: (SPF 5000TL HVM-WPV) came into my shop by customer and it has some wierd fault when the AC is plugged in and the AC charging current is greater than 20Amp the inverter goes into error 08. Remember this happens when PV is not present. I have upgraded the firmware using ISP tool but the problem still persist. I will be very thankful to you if you guide me?
Hello . My dear brother, I have a new Solar Inverter MKS II 5KW-B, and upon installation, the batteries were successfully connected. By mistake, a contact occurred between the solar line and the negative wire line with the body of the device. Strong shorts occurred and the device started reading 09 -- Note that the device did not connect to electricity The network is only batteries, In your opinion, what happened and how to buy or repair the damaged card, thank you
Hi, Thank you vry much for your videos. I have two MKS II 5KW-B. Both of them are not working. In one of them I got error 53 with battery source and no DC out. I found D20, and ZD3 short. I think i need to replace TrX7 as well. Any other componet that is worth to check or to replace in this case ? I do not know where to buy and what to buy for trx7 replacement. Can you suggest what and were to order. Alternately can I send you the two inverter for repair ? whoat would be the typica repair cost for this kind of problem ? Many thanks Regards
Greetings to all. I have a slightly off topic question but I have not found any other better discussion to get a sensible answer. I have an SMG-II-5.6KW inverter (I think hardware voltronic) and I have built a control unit and I read the parameters from the inverter but to optimize the battery discharge at high currents I have to write an inverter parameter on average 2 - 5 times a day. I wanted to know if anyone knows which memory chips use these inverters to save the parameters. I would not like to degrade this chip with excessive scriptures. I have not opened my inverter to not lock the warranty since it has seals on the screws.
Thanks for the presentation, I like it. But I want to ask, this type of inverter when turned on injects AC voltage to the PV input line. and when you touch the panel gives an electric shock, the shock goes away when the inverter is turned off. you will notice this while the inverter is on that the PV +ve to ground reads some AC voltage, and the PV -ve to the ground also reads some AC voltage. however, between the +ve and -ve reads no AC voltage except for DC only. one can believe this is a common-mode voltage injected from the inverter to the PV output. Please can you advise on how to correct it?
Please guide me about 1 issue I am facing that "one 3kva inverter came to me for repair, when we connect its output to load on bulb, its running but when connect on fan load, fan stopped and creates noise on fan". What could be reason, as 2 opto couplers are not getting ON. IGBTs are not short as well.
All of these Chinese made, high frequency, transformerless inverters are junk. If you want an inverter that's going to last more than a year, you need to buy a low frequency, transformer based inverter.
Excellent Job. Could you please help me with the solution of the following problem. I have Growatt 5000 Es. It shows Error 04 and 20 with beeping sound continuously. Nothing is working but beeping. Many Thanks

I want to thank you so much, this video saved me a lot
Thank you bro, Good job
I have some inverter but can not turn on machine. Can you guide me to check it
One again, thank so much!
Good tiching karte hai 👍👌👍👍👌👌👍
Thank you Sir, Good job

Good vadio
good work ❤eng
Thank you ❤️ ... Can you tell me what's the kind of power supply Which used to run and test inverter devices ?
Did you get an answer?
answer please...!!!
Good work Keep it up
Thaanks..
💐💐
I have an lv6548 and this is my problem, not detecting ac input and no transfer mode, batteries working fine, do i have to change the same things?
Try to do the same
Hello, I ask you for help with my inverter Sometimes it puts an error 55, what is the solution?
Thank you very much
Good ustad.

For safe and stable operation of the inverter
The grounding must be connected properly
Salam Sir you have to show ok capacitor value also
Please guide me about 1 issue I am facing that "one 3kva inverter came to me for repair, when we connect its output to load on bulb, its running but when connect on fan load, fan stopped and creates noise on fan". What could be reason, as 2 opto couplers are not getting ON. IGBTs are not short as well.
Check save power setting in the inverter if there is
And chack Hz setting
@@ALayoubiMaintenanceCenter how can we set power setting and Hz setting?
@@ALayoubiMaintenanceCenter by doing so, can the remaining optocoupler will ON.?
Can you share the circuit diagram of control board? Or explain the channels of control board
Thank you
Please wait for our next videos
Thanks ❤️
Sir my inverter is having same problem of not charging the batteries on wapda, can you give me the contact details and charges for repair

TL074 not TL047
Dear friend,
Thanks for your comment.
But I want to assure you that it is TL074.
Thank you again..
