powerjack power inverter 26,000 watt AMG version 48 volt PSW LF 13,000 watt continuous at 240 volts or 120 volts etc.

Ha, if the PJ 10.3 / 11.1 boards count as "tiny mini", then you haven't seen the scale comparison to a fully loaded Genetry Solar Rev. C control board.  They're about 2/3rds the size of the PJ boards...with AC input + charge + generator start + auto AC input voltage switching + FET current limit + AC input/output current monitoring, etc., etc.  (PJ board being ~6.5x7.5", GS board being ~4.5x4.5")

Probably somewhere around 160-180F.

I  seen your rev c board on youtube  and it  is  tiny .   PJ  making the rev 11.1 control board small is  trying to copy  the GS small  size .   I  like to  see  the size of the  main board or picture of the 12000 watt AMG mainboard  .   Helen of PJ  say  PJ  design  a new mainboard  even  smaller than the GS  mainboard  which has room for  2 capacitors and each   mosboard  has room for only 4  FETs .    

Nope, the 11.1 control board is the same size as the 10.3(c).  10.3 is actually BIGGER than the 9.0 it replaced.

Jack says the GS boards "may need to be a little bigger" 😉.

That design has been around for quite a few years already, and was used in their smallest inverters.  I've got one in my hand right now that's dated October 2007 (v2.3)

PV, if you get an inverter that will do 6500w continuous for $527 and all you have to add are some faster fans, then I would say you did well! 

I  like to know if it is a  ASL10 transformer core .   PJ  on Ebay did have a  ASL10 transformer on  sale  for 900 dollars  but no more .  A 5 wires ASL10 transformer will  do  8000 watts according  to someone on this forum  .

If  Scoops  12000 watts AMG  has that tiny mainboard with 2 capacitors  then  it will have a hard time starting an inductive load surge like a microwave  oven  .    That not enough capacitor  for  inductive surge .    The  price on ebay  is less than what I  pay for the 8kw  with  a mainboard  that has  4 capacitors  and  40 FETs .   Nobody will buy a GS 12kw  if they can buy a 12000 watt PJ on ebay  right ?   If  they  only know how PJ  lie  right ?

I can take a look at the main board, it looks like just 4 screws holding the board above it down?

I can see one of the caps, they are purple, not the black. 
The board on top says v 11.3

Bolivia information is not well documented . it is a landlocked 3rd world country that is rich in natural resources.

The one picture look like you  grow a lots  of  corn .  I use to  live in Iowa  where  the  corn field  is next to the residence and corn is everywhere .   I think Bolivia now has one of the largest lithium mine in the world .  

Not necessarily.  The capacitors in an LF inverter are NOT responsible for the surge capability.  Compared to the total load, they don't store any significant amount of power. 

The purpose of the capacitors in an LF inverter are to dampen the kickback resulting from the huge amperages, and prevent the battery cables from killing the FETs with inductive kickback.

I've never seen the "tiny" mainboard in anything except their "6kw" inverters or smaller.  But to be fair, they basically turn the "mid" mainboards into the "tiny" ones by putting only 4 FETs/board and 2 caps/board.

92 pounds evidently for the 26k AMG version. 42ks = 92.4 pounds approximately.

The  AMG  6 wires transformer  which has 2 separate  120vac secondary windings  around  one  core  can probably do  one quarter of 26000 watts  and so  max is 6500 watts  continue .    The  5 wires  ASL10  transformer can do  8000 watts .  The  problem  is that if PJ  can sell  a 13000 watt inverter for that low price then no one will buy a GS 12kw inverter .  The last youtube video say  Sean will probably sell the GS 12kw  for  2 and 1/2time   to 3 times of the GS 6kw .   

I more than seriously doubt it'll do 13kw continuous.  Shipping weight is too low, and I believe the biggest core they use in the "big box" inverters (due to weight and size) is the ASL9--which is only capable of 13kw+ if it's wound with copper.  And copper is triple the cost of aluminum, so I can guarantee that they did not use copper.

Expect 6-8kw continuous if you're lucky.

He did not say that.

What Sean did say was that the cost likely will not be a linear "double" from the 6kw.  However, the competitors sell a 12kw inverter for roughly $3500-4500, and our 12kw should be quite a bit less than that...with a lot more features.

$2500 would be a lot to pay. i am buying a separate 200 amp Square D Q main panel and 100 amp rated 3phase disconnects. the inverters have circuit breaker built in but I do not trust them. I have never paid more than $700 for the 15,000 and 20,000 watt inverters and only $527 for the 26,000 watt AMG one. i would have to go back in my records to see the exact prices of the previous models.

if they will only produce 25 percent of their claim, I will have to run more than one as I am doing at the moment to keep them under their heat/failure threshold. 

have to see what they send me via the so called speed pack shipping direct from china on the slow boat ride in about another 30 plus days or so.

PowerJack warranty is short but the cost to ship them anywhere essentially ends their warranty as it would cost most of the price of buying a replacement. maybe that is their business model,  disposable inverters. I  have 3 running 24/7 but at very low loads. 2 of them have been running continuously for over a year and the other one the 15000 watt 3 piece one has been running continuously since August.

the shipping on the 139  to 156 pound 7.5KVA transformer was 200 one way.

repair shipping is a killer especially when you have to ship it both ways and pay parts and labor after the 1 year warranty expires which only give you 30 day free shipping if there is a problem. 

the gs6 is $1099 on the website and 2.5 times that would make the price over $2500 plus shipping. that is what he (Sean) said on the last YouTube video for a price guestimate for the 12k gs inverter. I was thinking maybe it would be more in the 1500 dollar range. i will try to watch Sean's 12k promotional video again.

actually the 15,000 watt 3 piece ss inverter cost me $810 with tax and free shipping in 2021.

hopefully the PowerJack 26,000 watt AMG version is not a big flop. but at $527 including tax and shipping it is still a fairly inexpensive inverter. hope for the best!

Expecting only a $400 increase for double the shipping weight, more than double the internal parts, considerably bigger chassis, etc., etc.??

Costs are real.  We would go bankrupt if we sold the GS 12kw inverter for $1500.  But unlike even the "26,000W" PJ units, the GS 12kw inverter will actually do a solid 12,000W all day long.  I don't know if PJ even sells an inverter that will truly do 12kw continuous output.

The reason PJ can sell such big nameplate units for so cheap...is because they aren't capable of doing anything close to what they advertise.  Like always, you get what you pay for.

I use parts on GS inverters that cost considerably more than PJ...because they do what we want/need them to.  Our power button costs 10x PJ's power switch.  The GS AC input relays cost closer to 18x what PJ's relays cost.  And on down the list.
