inverter ac pcb problem

LED01G = 2 times (Red) Is this normal function of the inverter or is there any fault in my inverter. and possibly what is the cause of the smoke and how to avoide future accurance, sorry that could be difficult to judge without a practical testing because a smoke could be caused due to many different reasons.

Though the boosted response is an AC, it is still at the battery supply voltage level and therefore cannot be used to operate electrical appliances which work at higher voltage AC potentials. I have already answered to your earlier comment, you can find it in this article: https://homemade-circuits.com/2012/04/how-to-check-mosfet-using-digital.html?showComment=1437282049692#c5075736144765103392, inverter is a huge subject, it cannot be learned by just referring to a diagram or an article, you should learn it through an institute. If its hit by lightening then I am afraid the damage could be significant, it would be difficult to troubleshoot it without a practical examination.. LED01G = 2 times (Red) Hello sir.i have a ups Lebanon make.3700va,.it's now beeping n indicating inverter off/charger on from time to time.what might be the problem n what's the remedy for that. Daikin has been consistently developing inverter air conditioning system. Fault Code 28: This fault indicates a problem in the DC part of the inverter circuit; it means that the DC Voltage to the inverter is too high. I bought a Meissner Minivert 2000W low frequency inverter at an auction. You may have to diagnose the wiring, and what exactly the GFCI is detecting and tripping, you can one by one disconnect the wires from the GFCI and check which wire is causing the issue. Whether the unit is passing through 'wall power' or in 'inverter' mode as soon as anything is plugged into the ouput outlets there is a 'buzzing' / 'vibraton' and an overload condition. Thanks for the quick reply Brother ! Alright, I will do as advised. The fuse blew two days back and everytime I replace the fuse it blows again. 2 years is quite a long period of time and things can get faulty within this period, change it once more and this time tell the engineers to show you what exactly they are changing and also confirm the operating parameters of the unit….and do not give them the old module….keep it with you and check it afterwards whether it was really faulty. Inverters so connected with single battery because I have my 300Wp solar panel of 36Vmp so I have connected them in 24V from 12V & getting better result. Hi Daniel, if a PIC is involved then most probably this IC should be the oscillator IC driving the MOSFETs, however this cannot be confirmed without an oscilloscope. Hello Ahmed, please upload the images on a site where I can see them directly, without downloadingor you can share it through Google drive. I guess the tech man is right, the whole LCD module might need to be replaced, since the problem may not be related to inverter, rather an individual fault. Hi swagatamI have a sukam 750va inverter. But when I put the power plug into the socket, it works normal though mains have no electricity!! hell sir, my home inverter doesn't give output. Please advise. However I can be difficult to understand or judge the actual reason behind this damage, because normally the supply to the electronic stage is always regulated and through a step down transformer. Battery is functional as other inverter charges it well.Sir your immediate reply is solicited and thanking you in advance. Looks clean and net in all its parts. Outdoor Status = Off, Error Code = 62 my inverter is showing a short circuit warning. Hi Swagatam, My inverter shows battery low in 10 mins time, I have checked the distilled water in the battery and filled it. In US homes the neutral is grounded at the panel. Meaning out of the 4 set of mosfet only one set is different model. OK, then it seems the shorting of the MOSFETs might have burned some sections of the transformers too due to high current passage….in that case you might have to replace the transformer also, along with the MOSFETs, but only after confirming through appropriate testing, good morning sir…can share circuit diagram for inverter 5000w. When there is no fuse, it doesn't do that. i am repairing a invertec v270, i already replace the open capacitors with a new one. Specs: Pure Sine Wave, 2000/4000W, Charger (20A), with UPS. Check and remove such source or turn it off while using the air conditioner. Inverter AC PCB - Buy Air Conditioner PCB at best price of Rs 1500/piece from Wonderwash India. Case Of Error = Open / Short circuit Thanks, Hi Chidubem, you can add a low battery cut off circuit which will cut off the battery from the inverter, and stop from draining further. The following article explains a few of the basics of MOSFET protection that you can probably try implementing! This happens about 15 minutes after the mains loses power. still, you can try charging the batts externally and try again to see the effect. LED02G = 5 times (Green) Thanks in advance. Once the PCB board is repaired successfully and set the board in the air-conditioners so, it will be easy to use this device without any hassle. Welldone sir, pls, sir, i use inverter to my battery, and after charging i discover, that when i swtchon the inverter and load it, the mosfet will heat IMMEDIATELY and the tranformer is making noise, and the battery will bcome low. Yes, the changeover stage could be malfunctioning, it may be having an opamp sensor which is wrongly detecting a mains failure like situation due to some problem in the circuit. Instead of Schematic of that particular make , idea of control circuit (without mentioning component value of commonly available Home UPS/inverter will serve my purpose. I forgot to switch of my inverter as it was on when supply from public power supply feed into the and thus causing it’s mosfets (IRF1404 and IRF840) to burn. However I did that and also main transistors on both sides of power transformers (2) after trying to diagnose, I lost the steady green led. 26: this indicates that the compressor is the logic behind this most happy help!
