powerjack 24-volt 15000W lfsp inverter new 5-14-2021 manufacture

[pilgrimvalley]

a 3 piece stainless steel inverter. transformer in one box, control box is a second larger ss box and the 3rd ss small box is labeled thor's notebook and has the 2 lcd screens.

i will send pictures later . the transformer box said asl 6.5 i believe.

it came with a upower manual which does not correspond to this inverter in anyway.

it was sold on ebay as a powerjack inverter but there is no place on the inverter that has any brand naming that i can see.

trying to arrange 3 boxes in a tight space with interconnecting cable is the next challenge.

got it unboxed with no external damage and inside my solar power shed before the rains started yesterday.

also assembling a 32 cell 8S4P 1088ah LiFePO4 battery using 272Ah Lishen cells.

i have some other LIFePo4 batteries i can test it on eventually after bit.

needed the rain but definitely humid now.

[pilgrimvalley]

previous powerjack inverters had genetry solar label on the included manual. this one does not. evidently they are hiding the powerjack name a bit now. no new manual as this is an old manual which does not correspond to this inverter much.

[pilgrimvalley]

a couple pics. the transformer has one fan, the controller box has two fans, there are several cables to connect the boxes. it is not what i have seen before. cell phone pics are hard to get uplaoded on slow cell connection. more later.

[pilgrimvalley]

2 more pics.

I  think the ASL6.5  is a good transformer  because it is  30VAC  to 240VAC  and  may run cooler .    My   15kw Powerjack  has a ASL9  transformer  run 36VAC  to 240VAC  and  get  hot  so I run at  61 vdc  input  .   Yours maybe run at lower DC input .    Powerjack  doing a lot of changes .   

[dickson]

Sorry yours  is  24v input  so it is not  30vac  to 240vac  but  I  think it will  still  run cooler with the ASL 6.5  .   I  do not think  a ASL9   is in any 24v  15kw  powerjack .

[pilgrimvalley]

the above is how the website shows to interconnect the transformer and control board boxes. the transformer is on the bottom. the control box on top. thge Thor's notebook box with the 2 lcd screens is not shown but it likely hooks up in the other end of these 2 boxes. have not quite de-cyphered that part out yet. more later.

[pilgrimvalley]

it says 11.1 so i think that is the control board version; and at 60 hz on the box. thor's note book has 2 of the round screw on type 7 pin lcd cables which are about 7 feet long to connent the lcd screens to the other end of the somehow? have to turn it around. it is a fairly heavy >>>> the transformer and control box but there is a note that says to connect the lcd screens before turning on the inverter to prevent burning out the lcd screens. so have to figure that end out also.

[pilgrimvalley]

[pilgrimvalley]

have to look at web site for the connections a bit as they are not in the included manual. maybe Sid can make them a good manual! 😎

[pilgrimvalley]

our ac output as follows: 

2 ac output socket, output is 110v, also we have hard wire terminal-----L1, N, L2,

L1+L2=220V, L1+N=110V, L2+N=110V  

Note: can not L1+N+L2 at the same time!!!

 

• 15000W Low Frequency Split Phase 

• Pure Sine Wave Power Inverter 

• DC 24V   AC 110V,220V 60HZ

• • With UPS & ATS

  • With 110V Battery Charger

  • With 110V & 220V LCD Display Box

• AC 110V: 7500W continue power, 30000w peak power

  AC 220V: 7500W continue power, 30000w peak power

• • We separte the control board and the transfomer in two boxes,

  • so cusotmer will receive two boxes as photos show,
    
    one is the transformer box,the other is the control box

[pilgrimvalley]

so u can only do either 7500 watts at 110 volt or 7500 watts at 220 volt?  it says you can't do both at the same time what does that mean for wiring up a split phase inverter?

[pilgrimvalley]

the original listing said it would do 15000 watts continuously the after buying they updated the listing to say 7500 watts continuos. 7500 would work for most anything i would be using i think.

[Sid Genetry Solar]

@pilgrimvalleyFirstly, you bought a PJ inverter.  Consider yourself very fortunate to be able to reach 1/2 of that rating continuously...with a more reasonable expected maximum sustained continuous output of 30%.  Most "cheap" inverters utilize either deceptive ratings (i.e. advertising the peak)...or they will use simply fallacious numbers.

I will note that for wiring up a PJ inverter...the L1 / N output circuit more often than not has twice the transformer wire than the L2 / N output circuit.  But for practical purposes, this won't mean much.

I suspect that this has to do with the input circuit, which for 220v input inverters must only consist of L1 / L2, and Neutral / ground-bonded neutral must never come CLOSE to the inverter.

When I  first  connect my 15kw PJ  to the  main service  L1  N  L2   and it run  the heat pump  with no  problem  when  the  120vac  for the  refrigerator  and the  freezer was not running .    When  the  120vac freezer and refrigerator  is on  at the same time  as the 240vac heat pump is also on  then  L1 and L2   is way out of  balance  and the light flicker bad and  I shut everything down .   Now I  directly  connect the heat pump L1  L2  G  and no problem  with L1  L2  out of balance .   The  most I  get  is 6100 watts .   I  think  your ASL 6.5  is a  good  transformer  and will also run my heat pump directly wired L1  L2   G  .   PJ inverters  has no surge  protection .  Thank for your information .

do you ever think that powerjack may read your responses. in previous videos i obseved a 1500 watt inverter running 2600 watts. but this is their newest style inverter 15000 watts and is said to do 7500 watts contiuosly. i will not be using their ac charging or ups. only the off-grid 24 volt inverter hooked to a 120/240 panel. their warranty is not very good but it seems they have upped their inverters a bit. i have several 24-volt 5kw LiFePO4 batteries i will test it on in a few days hopefully.

i know they won't allow me to bid on auction after they had to replace the very heavy 20,000 watt inverter 48-volt lf sp psw that arrive to me as their 1st guineypig due to shipping damage; bad packaging. the powerjack seller names just change on ebay --- but still sold by powerjack.

this inverter arrived in 3 separate boxes from california in good condition. no physical damage noted. i hope it does 7500 watts without any problems...time will tell!

the 6000 and 8000 watt ss inverters have been running continuosly for months at low load though. expensive lights and coffee maker everyday and all night bug zapper.

this is a lot larger inverter than the 6000 and also a lot larger than the 8000 watt sp psw lf inverter i currently am running. i ran heat lamps in the barn all winter at about 200 feet away also for the baby hair sheep. you know they had to be born december 21st.

I  think  youtube is  block in China  but  people in Walnut  CA  will  read this forum  and is making  new style  control board and LF driver and is selling  ASL11  ASL10  ASL9  and ASL 6.5  transformer  on ebay  .   UPS  do  their fast  delivery  in the  US .    I  do  not think  ASL11  transformer can  do more than  10kw  continue  at least I can not  find any test in youtube  .    Me  and you are guineypigs  .  

[pilgrimvalley]

i wonder if they took business away from genetry solar due to the negative comments or negative reviews; which were more glowing sometimes on the early youtube videos? i am sure feedback goes back to china. when i complained and made a negative review they no longer allow me to bid on ebay. so they are a lot more shifty in teir ways of projecting their products. they chnge vedor names and change product names but still are powerjackproducts. no explanation just action reaction without explanation. 

if they read many negative comments, their reaction likely will not be positive. a company that has hundreds possibly thousands of employees working for pennies compared to what is paid in the USA. they do not advertise for genetry solar on their included manual anymore. just an observation.

before sean talked of opening a retail store with them in his videos, but now the rhetoric goes back and forth. my 24-volt systems are running Electrodacu SBMS0 on LiFePO4 battery banks off grid. there is no incentive to give power to the grid in south dakota where these are set up.

working toward a totally offgrid redundant system for the farm.

[pilgrimvalley]

i have been acquiing more electric appliances to test and utilize the solar pv power via the offgrid inverters. coffee everday and pressure cookers, bug zappper, led lights, 24 volt water pumps, 24 volt water heater elements etc.table saws etc.

[pilgrimvalley]

when you say the powerjack inverters has no surge protection? they just shut down due to overload or what have you observed? the battery charging from the solar panel is not an issue for me at this moment. i have a 400amp class t fuse between the inverters and the LiFePO4 batteries. two separate systems.

i am on process of assembling a higher amp (1088 amp) LiFePO4 battery at 24-volts currently.

is the issue when a heavy load starts and the surge amps are too high for the inverter? what problems have you encountered?

[dickson]

 when i complained and made a negative review they no longer allow me to bid on ebay

 

Is  that what  ebay allow the seller  do if  negative review ?   Other  in this forum  say  they  are also  block  in the US  and  from powerjack in China .   Now I better not  make any  more review .   Thank you .

If the surge amps are too high for the FETs, the inverter likely will blow up.  No surge protection as in, there's no way to instantaneously shut down if a short-circuit condition is detected.

GS 6000 watt  inverter has surge protection  and will shut down  at over  8000 watts .   The  15kw PS  will  start my   4 ton heat pump  because it do not know the 28000 watts surge because last  only for less than a second  and will  start  the heat pump  no matter what  .   The  15kw  now run  1 and 1/2  hour  with  Delta fans  and  will shut  when  temp reach 170 degree F  but  the voltage  drop fast and the square  wave cause me to manually shut down  earlier  .   I   let it cool  down 2 hours  because FETS  is 135 degree F   and  will  probably  blow up  all  24  FETS  if I restart  immediately  .   I  do not  want to be a guineypig .
