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

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  .

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.

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.

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?

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 .

Sid is  completely  right  and  I   did  blow up  all  48  FETS (now only 1 mainboard)  when I  just  got  delivery over a year ago  and  see  what happen  when  I  restart  with the  FETS and transformer  too HOT  .    That  why I wait  2 hours  because  there  is no  warning  when the FETS  will blow out  along  with the LF driver  .

if I wire L1 L2 and neutral to a 100 amp rated breaker box then it should be able to do either 120 or 240 at the same time. correct? i am not hooking it to the grid at all. most things i use are 120 but the kitchen stove is 220 and the oven is 220 and the electric dryer. the welder is 220 but may not hook that up to this. i have a generator i could run the welder on if i needed it.

it is rather confusing when they say you cant do 

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

Yes  and do not forget the ground  so there will be 4  wires to the main service box  and  make sure grid power is  OFF .   I  do this  in the winter  and run  the top of stove but not the oven and the microwave and  the refrigerator and the freezer and  all the lights and  (the 220 vac hot waterheater  for one hour)  at the same time  but not the washer or  dryer  or my 240 vac welder or 240vac heatpump .    Hard wire #6 awg  to the  main service entrance  from the inverter 3 terminals L1  N  L2   and ground terminal  and do not use the  outlet  on the box .    Use  a 50 amp  transfer  switch  like   the one for generator  or some other  way  on youtube .

Yes, it is highly confusing.  I could make several guesses as to why/what, but at the end of the day electrical reality is what will prevail...

I can tell you that the center-tapped secondary of the transformer is going to handle any set of split loads.  (L1 - N - L2).  That's how I wired up my 9k PJ when I first got it (and it still runs that way, although the only PJ parts left are the mainboard and chassis!), and how most users will wire it up.

Possible reasons why PJ would put up that note:

  • Overcurrent protection is only on L1 (deductively, L1 - N for 120v and L1 - L2 for 240v)
  • LCD "meter" reading is only on L1 (for 240v) and N (for 120v)

Pulling from the L2 - N circuit won't have any overcurrent protection (for what little good it does), nor will such a load register on the LCDs.  But it'll still work.

What Sid say is  correct  with the  PJ  inverter .   PJ  probably  say  do not  L1  N  L2  for  liability  or  possible lawsuit if people wired wrong using the  3  terminals  .  They want people to use the provided  outlets .   Wiring for  RV  is different  than  for  the house  main service entrance  as RV  do not  have  a ground  so is bonded  to the  neutral of the  inverter  but  RV  when  connected to  shorepower will  have the neutral  bonded  to the shore .   Let say  someone  use a sudicide  cord  connected to  a older house  with  3 wires  L1 and L2  and  ground  .   His house  will  burn down .   Must connect  4 wires  with   neutral to the house  to be  safe  or use  GFCI  like  someone with RV  in this forum .
