Hello, Hope you're doing well, I have a POWEDRIVE 3000w inverter that only powers small Fridge for example anything larger the inverter beeps an displays OL Any idea what could be the problem? Thanks in advance.
Dear Sir. I have a similar (sua 3000a) inverter also services badly by someone else. It is missing 2 ic over 3. It only has the tl 494. Anya Idea what are the other ones ? Thanks.
I exactly this type of inverter, the issue I started facing recently is that it keeps making continuous fault beep sound, and also it doesn't power on when plugged to AC current, please how can I fix this
Hi thank you for your question Well this type of inverter it has to types of transistors Input circuit use :irf3205 Or equivalent Out put: circuit use irf 740 Or equivalent .

Hey, What does that Variable resistor do? In the top left of the inverter(color=Orange). Can we set the battery's low voltage by ourselves with that variable resistor? Please reply
Hi thanks for you question Well in the model i repair it is to set the output frequency to 50 Hz In other models i dont know i will have to see the circuit
my inverter not working after i wrongly connect the dc terminal, pos to neg and neg to pos.. can i know what is the problem and can it still be repaired?
Hi thanks for your comment If you reverse the polarity of the battery poles, it is certain that the internal fuses have failed and must be replaced, and in order to replace them in this model, you must open the device, remove the transistors stabilizers and completely remove the board B from the metal casing. Note if you do not have experience in dealing with This type of device, and you have not previously maintained this type of device or any similar device, take the device to a professional because this type of device produces deadly and dangerous electricity I hope that I have answered your question.

Same inverter my inverter still produces 350v but the high voltage mosfets gate only one of them have signal whats the problem on my board ist the lm324 ic or tl494? Itriedto replace the tl494 and its still the same
Hi thanks for your question. In fact, the presence of 350 volts on the poles of the filter capacitors means that the converter circuit is working fine, but according to your words, the absence of a signal at the MOSFET gates means that there is a problem. Either with the tl494 controller or with one of the elements in this circuit. Check all the elements carefully And replace the tl494 with a new one and the problem will be solved I hope I answered your question .

I have the same inverter and I'm facing a problem with My battery is fully charged but the output of the inverter is only 94 volts instead of 220! Is there any suggestions?
Hi, thank you for your question. According to the fault you mentioned, I expect that there is a malfunction in the shoper output circuit, such as a disconnection or a break in the board. You must remove the cover and check the output of the transformer at the poles of the smoothing capacitor. The voltage should be from 290-310, less or more by 5% And after this step you can narrow the problem. ☡ Please, this device contains a high voltage and is fatal.

Yes you are right 👍. I have also noticed short length and low quality cables used for inverters and battery chargers. 2nd problem is no setting of voltages and ampere for chargers.
Hi thanks for your comment First of all this model is an inverter not a charger The second thing for what you are saying a beep sound is indcation for a 1. A low power battery will do this sound so to check the inverter just hook it up to a new battery that you know is good and have a good charge in it and turn it on with no load and see what will happen if it works that is ok if not than this mean that you have a proplem in out put mosfet you need to open the unit and test them (irf 740) Notice this unit is made to make 220v ac and this voltage can kill you if you dont have knowledge with Electricity and you do not know how to deal with these devices, please take the device to a specialist to do an inspection or repair if necessar Please like and subscribe to the channel & activate the bell button so that you will receive a notification when I post any new video

Hi thanks for your question this model is an inverter only it dos not charge the battery but if you mean that the red led is always on this mean you have a problem in the out put circuit
I have accidentally plugged in my 500w saa-500af and all 3 transistors are blown! It also damaged the board trace where those transistors are. What can I do to fix it?
As for the maintenance of the inverter its possible as long as the board is in acceptable position if there is a burning board and I mean here a strong burn must be removed and re-linked lost trace by using a jumper wires and compared with another device of the same brand and you have to test the trans and other parts in order to see the blown part
Thank you. I have subscribed. The three transistors hy1906 (two pieces) and fdpo47an seemed to be the only ones that were damaged but the board where the center DC transistor (hy1906) trace is burned. Are there any alternative transistors for those two? Do you have an email address where I can send you an image of the blown part?
I'm sorry I do not have a schematic for this device because china do not give schematic for their devices but I have the same device I will publish a hand schematic for it in up coming video soon so stay tuned for it

@@mahmutkurt9884 Hello again 1. this model does not have a cpu. There is an IC generating oscillation signal TL494, and it controls the transistors and the MOSFET. 2.the output on the poles of the capacitors before the current conversion circuit from a dc to ac is 325 to 350 volts. That is normal You can check the frequency by using a Frequency meter and by using the oscilloscope and by measuring the multiple voltages On the tl494 pins. 3.
