My 600w inverter tripping at 400w after 30 seconds

[giftslayer]

hi know this is probably not the best place to ask this but this is the only place that has not removed one of my post for stupid reasons (like Reddit keeps doing for asking things)

if their a better place to ask this pls redirect me instead of removing my post saying quoted form Reddit users ""my question is not direct enough""

 

i have a meanwell a3001-600-f3 that keeps tripping after 30 seconds on 400w load so i was wondering what it could be that is cousing it so that i can replace it bc repair stores near me ask me 80% of what a new inverter cost so i rather repair it myself

can anyone help me fix this or at least what it could be

i know their is risk in repairing this kind of things. i always ware gloves and discharge any capacitors

 

hear is some photos

dont wory abode the fan plug thats out i will fix that with a new fan

look for burnt areas around transistors, capacitors, and trace line. also look at the connections the solder has not lost contact. also check all internal fuses, might even be worth replacing them depending on how old the converter is.

also looks like J45 in the bottom right hand corner is bent double check that

What type of load? If its not a resistive load, it could very well be pulling 600w+ if the power factor is bad. Also, those inverters usually state their peak power as their box figures. So it could only really be a 400w inverter with a 600w peak.

 

It is from meanwell though and they make damn good stuff...

take a look at the jumper on the bottom right hand side do you see what i see?

I see an improperly installed jumper

 

If its making electrical connection on both sides, I wouldn't worry about it.

I thought that too, but according to the Data Sheet and test report sheet, it's capable of running a 600w (580w test) continuous load with 1200w peak power for short periods of time, so I'd say there's a failing component somewhere in the circuitry, or something is tripping the overcurrent / overload protection after some time at high loads.

 

@giftslayer you might need to take it to an electronics specialist if you're not comfortable or skilled at testing electrical circuits. Inverters are often some of the simplest circuits, but even I wouldn't know where to begin when it comes to actual electrical circuitry.

if the OP feels comfortable working with a live unit he could test the power coming out of the transformer.

it might not even be the unit itself though, it could be the battery not capable of delivering 600W, so it shorts out and trips the unit

ok il will check that

i testet it on a pc the pc is about 350w and in trips so the tripping W just got lower a 400w light bulb but a 150w tv it runs ok but the weird thing is that i notist the overload led led dont chage when it trip and the green led stays on

 

so i am olso wondering if it could be not sure but is it posible that the battery cant handell it?

Do you have a multimeter? A weak battery sounds plausible

well i dit fix a wie thigs in my life bc the reipare shops near me ask me 80-60% of what a new one cost just to look at the things, so you kind of get handy with fixing thigs

i have comfotable-es with testing power like alwase be cousios and ware my gloves

dint se your post after i ask abote the battery i will try it with matiple batterys in paralel and sea if it goes higer

 

just learned to multi quote

My guess is either your DC power source is sagging below the voltage threshold for the inverter, your load is larger than 600w, or the inverter is overrated.

well i know the ligth buld it 400w and the led ligth doesent say enyithing of overheating or overloading it just stays green

[giftslayer]

ok we can rule out the battery i tested it with 4 batterys and still does the same

 

also the overload led or over temp led does nothing and after the power is cut the green normal led stays on

 

but next il check for burns on the board / solder points and then il test the transformers

Does the PC have a modern PSU with active PFC ? If so, try another load...

Active PFC works by drawing short current pulses right when the voltage sine peaks in order to get good power factor.

But those short pulses are then multiples of the average amount of current, those large spikes could cause the inverters safeties to kick in.

i dit try it on different loads like a 400w ligth bulb its 30s then the power cuts on the pc and the ather loads that i have tested abave 350w below 350w the power does not cut at all

i opend it up and i dont sea eny burnt part or suspisios solder conections and the jumper that looks loos is connectit its just longer that the rest that why it look desoldert

buy or see if you can rent a power output DMM plug it into the inverter and see what it put outs before shutting down.

[giftslayer]

i don't think this will be fixable i think its the chip controlling the led bc nothing seams wrong i tested the output and nothing supitios their
