Unfortunately it isn't 😉. Tag shows specification winding voltages (whether the actual transformer matches this or not is a different question!)
Only real way to determine how much wire is on the tranny is to count the number of strands.
5 minutes ago, NotMario said:So this is actually a U-Power. And it's the voice that says it. She tells me to check "this board" "that board" and lists off like 6 different boards.
Ah, the generic "inverter self-destruction" error 😉.
Have you had the interest to try running an efficiency check on the PJ inverter? 7kw in for 5kw out (yes I know those were completely ballpark estimates) is closer to 72% efficiency.
7 minutes ago, NotMario said:The transformer looks like it uses copper wire. (IDK, maybe it's copper plated).
All the PJ in-house wound transformers (which is all of them!) utilize enameled aluminum wire.
People might squeal about aluminum wire--but aluminum wire is 1/3 the cost and just over 1/2 the weight of copper...and if it does the job, then there's no reason to change it to a costlier choice that doesn't provide any needed benefit.
10 minutes ago, NotMario said:As for the GS. It passes my "practical application" requirements with flying colours.
I have to ask: the PJ "just for fun to play with", a backup, or...??
Any specific GS feature requests? I'm getting ready to release 1.1r6 this week hopefully (want a beta tester or 2 for charge, haha!), and will continue to improve it as I can.
(split this conversation with @notmario to another topic in Genetry Solar inverters:

so the PowerJack 26000 watt AMG version should do a fair bit more than the 12000 watt AMG version? cross my fingers behind my back 🤔
I will just have to wait a bit more before it arrives to find out.
it is coming from china:
| Standard SpeedPAK from GreaterChina for $199 shipping cost>>> the slow boat ride is expensive! |
I am glad to see some people reporting their tests and experiences with the AMG version inverters.
it sounds like the electrolytic capacitors will be a failure point in inverters before the LiFePO4 batteries or the solar panels;
hopefully a better inverter design comes along for long term use!
what is the capacitor lifespan of the GS inverter?
February 23rd, 2022 >>>>the PowerJack 26,000 watt PSW SP LF 48-volt AMG version arrived by ups today. it has six feet to support it on the bottom and lucky the ss brackets may have saved it from the shipping damages. both brackets were bent a bit but all seems intact anyways.
I just watched a 2 week old YouTube video where a guy had a 12,000 watt AMG version and he had it doing 4500 watts but not the 6000 watts. this 26,000 watt inverter is supposed to do 13,000 watts continuous so maybe i can get 10,000 watts continuous >>> who knows...no one has shown what it can do....anywhere I have searched....
Sean will have to do his load tests if he ever get one in....
odd it came with the old style manual (with the bikini clad girls for your amusement) that does not even talk about the AMG version, but it does have their new warning sticker on the side......did not take the lid off yet. too many things to do.
man handle it inside 38.8kg net it says a ASL5 transformer i believe if you can read their writing. 11.3 board...unbox the beast by myself,,,unbolt the shipping brackets... manhandle it up on a coffee table...the lift table is in the ice-cold garage and it is below 0 so i punted on that thing...man handle it is...
my back says you suck....
(better than the 180 pound liFePO4 batteries though going up the steps.)they were arm stretchers with a 2 wheel cart.
so the slow boat ride took from 1/12/2022 ebay auction winning bid to 2/23/2022 >>> 40 days to arrive to south Dakota from China on the slow boat ride including going thru USA customs....for $527.73 total out of pocket (delivery included, and the sales tax they impose via ebay)...
some brave soul will have to load test it.
I bought some thick 4x12x.25 inch plated copper busbars to make a bigger LiFePO4 battery...slow but sure...
the foot print of this thing is very large....need to build a bigger solar power shed... i think it will ultimately be a garage/solar power shed for more power....arr arr arr... come spring when cement can be poured....
faster delivery than the LiFePO4 battery orders anyways...via their slow boat ride from China....
the inverters had the off-grid solar power shed at 58 overnight so i turned on the heat lamp bulb this morning. the 3 LF inverters put off enough heat all by themselves but the batteries like it better at around 70 degrees...me too...
man handle it inside 38.8kg net it says a ASL5 transformer i believe if you can read their writing.
By weight and core size...count yourself extremely lucky to reach 7kw continuous. That's the reasonable max we can get out of the ASL5 core with a maxed-out winding spec (which I doubt the PJ winding job is).
the you tube guy with the PowerJack 12,000 watt AMG version said he paid 300 dollars on ebay auction for it. he has fluke meters and an oscilloscope and shows some pretty good details for the 12000 watt one which is supposed to do 6000 watts continuous. so maybe they have made some upgrades.
now if they could be paralled to increase their power...woo hoo...
maybe the gs inverters will get that worked out in their new 12k version....
now if they could be paralled to increase their power...woo hoo...
Paralleling is extremely difficult at best...as I keep telling Sean.
With the latest Rev. C control board technology, parallel should be quite feasible on GS inverters AFTER I get the code written for that function.
Sean will have to do that video of stress testing them when he gets more battery power... i am still building other things...no time for that right now.
one place it say 42 kgs . i have a scale coming in a couple days... their weights are likely the same as their math skills. at any rate a beast for a retired fella's back!!! likely trying to cheat on shipping weight ( the china way of things)...
the main entry to the Molino doors are done. February 4th,2022. the electric there is a 2 wire 220 volt. there is no 3rd wire to any of their 220 volts there. this is the front side about the middle of this construction....summertime there. raining like cats and dogs and everything is growing fast...Bolivia, South America
wood-fired outdoor kitchen is almost done February 21st 2022.
and pizza oven is almost ready
self-sufficiency off-grid is the goal and to build super cool stuff...in the remote mountains...planted blueberry, fig trees, this past week and raspberries....
off topic but to import anything there is a 33 percent import tax to bring almost anything of value into Bolivia so all the politicians do the same thing... world-wide legalized robbery....
i have been stopped through the airport and made to wait a lot to pay their tax...
where is robin hood anyways???
good night all,,,

have you counted the strands in any amg version... ????
how do they get 12,000 amg; 16,000 amg, 20,000 amg and 26,000 amg inverters? each one has different size and weights and physical case size etc....
the yellow warning label is attached about the choke on A/C side aka warranty disclaimer....
the warranty card says to sign up to get a 15 month warranty at their website....with albee gong...
USA.www.powerjackpowerinverter.com
there would be no way of telling by a label anything about a PowerJack inverter is what you are saying ....????
so no way of telling what may be inside a January 7th, 2022 26,000 watt PowerJack psw sp lf amg version inverter without tearing down the transformer and counting the strands???? that is not going to happen!!! that is a Sean basement test/ torture scenario! beyond what i am going to do to it!!! ha ha ha 🤣🤣🤣
my question is how long will the electrolytic capacitors last in these transformers??? that is the weakest link if they now shut down when they get too hot as shown in the youtube video posted 2 weeks ago...about the 12000 watt amg version PowerJack i just watched...
what is the life expectancy of the electrolytic capacitors???? and in the GS-6k and GS-12k inverter what is the life span of these Chinese electrolytic capacitors???
how often will these have to be replaced??? or trash canned??? the electrolytic capacitors???
the only relevant instruction are on the lid, but nothing about choke .... how to do it.... seems like the wrong label as it says it has a charger which it does not nor did i want that .... just an inverter simple w/o extra fluff....
time to go check the critters outside soon....
oh no >>>> it is 7 degrees below 0 Fahrenheit out side.....darn...
check the off-grid solar power shed 1st...it is always the warmer refuge ....🤔

I just watched a 2 week old YouTube video where a guy had a 12,000 watt AMG version and he had it doing 4500 watts but not the 6000 watts.
Edit previous post . I can see it is 32vac primary like the GS 6kw transformer but can not see if it is a ASL4 or ASL3 . He only test with the 120vac option so about 2200 watts max on each leg with out the red light alarm . This is about 4400 watts total output on both 120vac legs . Max 2200 watts on one leg is 20 percent of advertise output because 3000 watt on one leg will give the red light alarm in the video . This inverter probably can not do L1 N L2 240vac inductive load like welder or microwave oven as he only do resistive load like hair dryer .
he said he only paid 300 dollars to get 4500 watts out of the 12000 AMG PowerJack version,,,,, not 220volt the way he was doing it but would be a very inexpensive 13500 watts for only 900 bucks on ebay....
i have not seen any other actual videos,,,,so it was interesting to see his results....
he was not starting any big motor loads or anything. maybe i will message him to see if he has any more to show or report...
he seemed to know his way with fairly good test equipment... i am always trying to learn more to prevent the ,,,uh oh dum dum mistakes.... i learn a lot by them but costly at times....
i think i will pose some questions at the manufacture end of it....to PowerJack warranty end.
i bought a big PowerJack choke for 1 dollar plus 40 shipping from them but never tried it...bought on ebay auction but never see it on auction since....it is in a ss box also...
this 48-volt 26,000 watt (AMG PSW SP LF) one i repositioned in the early hours to test inside when i get a bit of time...need to make some big cables up to combine a couple LiFePO4 batteries 1st....it is definitely not a wall mount inverter... it is wider than the 15,000watt big box ones of previous years but the length is shorter. 18 10mm bolts to pop off the top... but have not got to that...yet... two fans in one end,,,
have to do somethings when the children are sleeping so the tools don't grow legs...
thanks for your replies...
still a heat wave outside at 4 degrees below zero Fahrenheit.... good old polar bear weather!!!😎
so no way of telling what may be inside a January 7th, 2022 26,000 watt PowerJack psw sp lf amg version inverter without tearing down the transformer and counting the strands????
Just slide the white cover up (if present) and count the strands. You may also be able to feel the difference between 1-3 strands through the white cover on the AC high voltage sides. Low voltage side will have shrink wrap, but you can easily count the strands there as well.
my question is how long will the electrolytic capacitors last in these transformers??? that is the weakest link if they now shut down when they get too hot as shown in the youtube video posted 2 weeks ago...about the 12000 watt amg version PowerJack i just watched...
I have no idea what video you're referencing; I tried to find it, but was unable to turn up anything relevant.
As long as the caps are of decent quality, and there's enough of them...they shouldn't have a short lifetime.
have you counted the strands in any amg version... ????
Nope: I've never had an AMG version PJ in my hands.
He only test with the 120vac option so about 2200 watts max on each leg with out the red light alarm . This is about 4400 watts total output on both 120vac legs . Max 2200 watts on one leg is 20 percent of advertise output because 3000 watt on one leg will give the red light alarm in the video .
Red light "overload" alarm is only one one output phase--not both. You can overload the other phase until the transformer overheats/inverter fails, without an overload shutdown.
This inverter probably can not do L1 N L2 240vac inductive load like welder or microwave oven
Oh come on now...if it's a split-phase output, it'll do 240v output. No magic going on here.
