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

it seems they are selling or at least offering for sale less of their older style inverters. but they get more confusing in their wiring

The last youtube video  by Sean  say people call  about  a powerjack  manual  on how to  wire  L1  N  L2  and a lot  of PS  inverter are return  because of miss  wired .    The  new   AMG  powerjack  inverter  suppose to make  for less  return  because  it is wired for  120vac  on option A   and    wired  for 240vac on option B  .  There is no  warranty if wired L1  N  L2 but  it can be  wired  L1  N  L2   if you use option B  but do not tell powerjack .   I  do not think Powerjack  know what L1  N  L2  split phase  mean .   It  mean  L1 is 120vac  and L2 is 120vac  to be  perfect balanced  and not  L1 is 116vac and  L2 is 104vac .   It  takes  15 more turns  of wire to make   L2  to  get 116 vac  to match  L1 at 116vac .  They save a lots of wires .  

24-volt 15000 watt LF PSW SP specific question:

Can you tell me the transformer voltage of the powerjackASL6.5 transformer? what is the output of the primary winding and what is the output of the secondary winding?  so then i can understand the transformer function a bit better.

this is for the powerjack 15,000 watt LF PSW SP 3 piece 24-volt stainless steel case inverter. the heavy terroidal transformer is in its own separate ss box with 1 cooling fan, the control boards/boards are in the second ss box with 2 fans, and 2 lcd screens are in the 3rd ss box (aka thor's note book).

i have it connected and running on a 5kw lifepo4 battery at present. i hooked it up to only 2 of the DC 24V in put, positive and negative (it has 4 >>> 2 positives and 2 negatives) i taped off the unused positive and negative input terminals. for safety so i do not accidentally short something out. 

thanks in advance! 😎

what is the output of the secondary winding?

The primary signal IN  is the  input voltage to the transformer primary winding  which come from the  LF driver is  16vac to 18vac .  The  transformer  need  AC  to function .   The  control board  convert the  24v  dc input  to  18vac to the transformer  is what the signal IN  gauge  on the box show  and show the LF driver is working .  The secondary winding  convert the 18vac to  240v ac measure between L1  and  L2  hopefully .   L1  N  should be 120vac  and  L2  N  should  be 120vac .  Can you  show  what you measure  between  L1  N  and between  L2  N  ?     My  ASL9.0 transformer  measure L1  N  is 116vac  and L2 N  is 104vac which is 220vac  .   This is  not good  for  wiring L1  N  L2   because  unbalanced .   That is why  Powerjack do not want people to wire  L1  N  L2  but can be  done if  the ASL6.5  is balanced  120vac  and 240vac .

115.8 volts L1 to N; 107.5 volts L2 to N; using tacklife meter on the front of inverter. nothing plugged into inverter right now.

hmmm?

so how would one get L1 and L2 balanced? 

the kitchen stove would be my only 220ac use in the future. not hooked to the offgrid solar yet.

Unfortunately, this is a hardware issue with the way the transformer was wound.  And doubly unfortunately, the low voltage side is on the OUTSIDE.  Technically speaking, if you can extend the "line" wire for the low phase coil, you can add another couple of turns to that wire on the transformer core to raise the voltage. 

Assuming you know how transformers work 😉

Oh no  ,  I  was thinking  ASL6.5 the  L1 is  120vac  and  L2 is  120vac  .   The  low phase  coil  107vac  need  10  to 15 more  turns  to make L2  be 117 vac .   Now  try to  not  use  inductive  load  on L2  like air compressor or  well pump  or  large freezer  or microwave .     I  think Powerjack  save  a lot of  wires  with split phase  being  220vac  instead of 240 vac .

I  use  my  15kw  powerjack   L1  N  L2   in the  winter  running 220v  stove  and  water heater  and portable heater no problem  with  resistive load .      Thank  you for the information  of the ASL6.5  voltages .   

still learning about how transformers work; have to look into adding more windings in the future. to balance the transformer. 

next question? i could use more than one 24-volt LF PSW SP inverter on one battery bank.... correct?

and each inverter could run their own specific loads! right now each inverter has its own 24-volt LiFePO4 battery. two are 16cell 272Ah 24-volt batteries at 544Ah. teh 3rd battery i am assembling at present is a 32 cell 1088Ah 24-volt battery. the 16 cell batteries have 13,926.4 Wh potential capacity each (nominal voltage at 3.2 but actually more than that).

the 32 cell 272Ah build will have 27,852.8 Wh potential capacity but actually more than that. each has its own BMS >>> i am using the Electrodacus SBMS0 for the BMS.

i have 4 separate 100 amp ac panels and plenty of breakers. maybe only one inverter would be needed for a 220 volt ac wiring. the other inverters could all be 12 volt wire into 100amp AC breaker boxes.

the intent is to get all off-grid and use as much electric for heating etc in the winter. i believe electric will be the way to go. trying to get away from propane and grid supplied electric.

the inverter is the weak link at the moment. and trying to keep the solar power shed cool has been a struggle this summer, but the weather is starting to change a bit as summer winds down. I open it up at night and morning as much as i can to cool it down. possibly install a small ac unit in the future for the solar power shed where all the inverters and LiFePO4 battery is located (to keep it safe from the curious people).

just killed a bat ---- don't tell the wife!!!

here are the 2/0 baterry cell interconnects >>> waiting for shrink tubing. this is for the 1088Ah battery build! 😎

No hesitation, go right ahead 😉

excuse any typos i meant 120volt ac but did not see it in a post above not 12 volt. i am not doing any 12 volt all are 24-volt and 48 volt inverters. the blind man tries to find his errors before posting.🤓

not really blind just a poor typist who needs reading glasses but buys 1 dollar cheater glasses at the dollar store!

sorry for any confusion.😎

You can edit the post...click the 3 dots at the top right of the post, and you should see an "Edit" button among the other options.  (You'll only be able to edit your posts.)

you can only edit the posts for a short period of time. possibly 30 minutes or an hour. if you find something after the 30 minutes to 1 hour time limit the 3 dots at the top no longer are there to allow editing. i have made several typos and later found but was not able to edit. there is a time limit to edit and i do not know what that time limit is exactly; but often i type and later find the dumbo typo ... but too late to correct it. 😎

OK. 

 Question: What is the purpose of the "power sav" on the switch?

when I put the sweotch in "power sav" position, the voltage gauge bounces back and forth as if looking for a load. when i turned on the multistrip which had a small tool charger and the hamilton beach coffee pot plugged in it would not start the coffee pot or start anything. 

what is the purpose of the "power sav" position?

 to me it does not work because the inverter could not start anything.

when I swithched it back to inverter on or not on the power sav then the  inverter functioned correctly and now the coffee is brewing as i do every day.

thanks all. have a great and relaxing Labor Day weekend! 😎

what is the purpose of the "power sav" position

The  power sav  is the  OFF position  of the  switch  and will  never  power anything  .     Without  choke  the inverter may use  50  wall just  to  keep  itself  power on with  no load  .   With the  switch in power sav  the inverter  my use   10  wall  with no load  and make your battery  last  a  tiny bit longer .   I  never use power sav  because  I  have  40 thousand  wh lithium ion  battery at 60 v .
