i removed the transistor from the first unit, how do i check to see if good? 

i get a .6  diode reading with black on b red on C, but OL on all other combinations,


what is the wattage of the resistor, i can probably get one of those locally.




If it is convenient, could you please get the parts from the first inverter


Or we can send you the parts via china post ,generally,can be delivered within 2-3 weeks

Hello  Curtis,

In fact, with the current test data of No. 2, it is normal, but it is inaccurate to judge its condition on this basis alone, and it needs further verification by other equipment, which cannot be done on your end, so in order to ensure that the inverter can be restarted, we think it is best to replace No. 1 and No. 2 at the same time


Please check the videos in the attachment , please add the part No. 1 ,No. 2 to the motherboard first and then solder it to the back of the motherboard with the metal tin and the soldering iron

hello,

i went to the first burnt out inverter, which has no damage in the area, and remember that the display worked before burning out four of the main transistors.

i got the same results!

resistor disconnected, (which is not burnt at all)

positive on a b was 1.8 and c 2.25

negative on a and b slowly up to OL and c .64


Same as the second unit, so if this is the problem, it is on both. or there is a different reason too many amps are overheating the resistor.

On the second unit, i shut it down in seconds where he first unit was on for minutes and totally burnt out. 



then on the burnt out unit, I removed the transistor by cutting off the three legs (i could not un-solder all three legs at same time)

so with the transistor out of the unit, and putting the test probes on the solder sockets, i got the same readings!

negative on a, then b just increases to 2.99 and OL in a little over a minute, A to c is same .64


we are not making much progress. Are you  sure  you don't want me to send back so you can figure out the glitch and make the units more reliable?

OK, here is the results:


before i disconnected the blackened overheated resistor, i measured 10 ohms across the resistor, and .5 to .6 on the diodes (with black lead on black end of little tiny diode), switched leads and both read 2.87 to 2.89.


then i un-soldered the resistor,  measured the same 10 ohms across the disconnected resistor and same .5 to .6 across the diode.  But when i reversed the test leads, (red lead to black end of diode) the diode meter slowly increased past 2.99 to OL.


With the resistor disconnected, the transistor reads slightly higher than reported below.


what does this tell us?

Dear Curtis,

Sorry for the delay

Please check the picture below


Repair the second inverter involves the four parts marked in the following picture, it has been determined that the No. 1  has been damaged, please remove the No. 1  first, and then use a multimeter to measure the No. 2-4 , No. 2 and No. 3 are diodes, for diodes need to measure 2 times, the first time with the positive and negative pole of the multimeter to measure the diode,the second time,please adjust the positive and negative terminal of the multimeter, and then measure the two ends of the diode.Please see figure 2


We will determine the condition of #2-4 based on test data

Hello


it is a re-purposed standard 36 volt forklift battery, that was fully charged to 41 volts.

with positive test lead on terminal  "a" in your photo, meter set to diode reads OL, then when I touch b, it reads 1.8v and 2.2v to c

with negative  on 'a', then to b is 2.4v and to c is .64

the totally burnt out unit reads very similar.

yes only that blue resistor was smoking and is burnt. no other smoke or damage noticed, but then it was only on for maybe 20 seconds total.  But the LED numbers never came on, or even blinked, so something in that system is the core problem.

except for the positive and negative battery cables, there was no other wiring connected.

that same blue resistor is good in the first unit, and the voltage lights worked in that unit, not the same point of failure.

Hello Curtis,

Sorry for the delay

You mean the blue resistor in the picture below, correct?

Is this the first time you turn on the inverter, is the wiring the same as the previous inverter,is there a change in the wiring somewhere?

Besides the blue resistor, are there any other obvious signs of damage inside the inverter?

Hello Shirley,


I turned on the replacement inverter  and it immediately began to smoke.   I could not believe it. So disappointed.   Here is the process:

I connected the battery only, checked polarity, measured very little DC current (clamp on DC meter, so not real accurate at low current).  

All good on the DC side, Output terminals not connected yet.  wanted to test before that step.

Switched on the inverter, and no sound, no lights or numbers on the display.  Then within seconds, saw smoke.  turned off immediately.

sat there in sad disbelief. 

I removed cover, turned on again and watched, saw the blue resister next to the ribbon connector getting hot and smoking, check and inverter was drawing about two amps DC.

again no sound from inverter or lights or blinking on front. no AC connected to output, did not leave on long enough to measure output voltage. turned off within 15 seconds and removed unit.  reinstalled old AIMS modified wave unit. so sad.  


Please see attached photo.  The right blue vertical resister below the ribbon connection to board, is black around mid section and is clearly where the smoke was coming from.

Subject: Re: Fwd: 36 VDC 8000 watt inverter-1184

Thanks, I just want to avoid whatever caused the first unit to fail.   
So to be clear, the battery negative, building ground  and the inverter AC  neutral black are all bonded or connected within the building wiring,
The red hot line is connected to the panel breakers. 
But the inverter ground (yellow/green) is left unhooked and floating.  ground terminal screw on case is not connected.

thanks for your patience Shirley
