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

[pilgrimvalley]

Wonder if the 26,000 watt one will do 13,000 watts continuously that it is rated at. this is one of their new style AMG versions. it is a PowerJack brand and seems to be what they are promoting now through eBay. this one does not have ac charging capability which i do not want at this time for the off-grid solar builds.

I scored one for $527.73 including tax and shipping new on auction yesterday.

has anyone seen one of these in person and hooked it up to test it?

26000W LF SP pure sine wave power inverter DC48v TO AC110V & 220V, AMG VERSION

it is estimated to arrive in in about 60 to 75 days. slow boat ride route they call speed pack.,,.. ha ha ha but i have lots of things to keep me busy until it gets here anyways.

Sid say PJ does not understand the American "split-phase" power system.  As far as they are concerned, the inverter outputs 2 voltages, "220v", and "110v.   I  am sure your inverter will not do  one half the rate advertise .  Base on the price the inverter will  do less than  one quarter advertise rate .   Having a 6 wire transformer  will give more power for 120vac  but will not be good for  L1  N  L2  split phase circuit .  240vac is ok if  direct wired to the load .    Ebay now sell the 12000 watt AMG  for a lot  less than the  8kw that I  bought .   That tell me  something is  wrong  with the design  and  getting  less power .   I do not know what PJ  engineer is thinking  .   It is not a BMW  AMG ev car 

[TheButcher]

In all seriousness, it's a PJ.  Do you really need to ponder that question?

[TheButcher]

AMG probably refers to the design of the inverter, At Most, Garbage (that's my dig for the day).

You are right .  If  I  use  my  15kw  running the 4 ton heat pump for more than a hour  it will be a  AMG  PJ inverter .  It happen  when I  test  my 15kw  2 years ago  and will now use it  to  run less than  4000 watts .   After 2 hours  the 15kw  actually  blow up  FETs  LF drivers   mainboard  and capacitor  like a fourth of july fireworks  because it overheat  .

@dicksonDon't have to look much farther than your screenshot...how about 6kw???

That's the result of some very poor FET driving 😉.

[pilgrimvalley]

so if you guys are right the 26,000 watt PSW SP LF PowerJack power inverter AMG version will possibly do 6500 watts continuously for $527.73 including tax and shipping.

perhaps they put some SID designed parts in it. i ordered some 48-volt Delta fans so may help to add some extra cooling. right now the extra heat form the 3 inverters is helping to keep the off-grid solar power shed toasty in the snow.

the inverter is the weak link in my off-grid system at the moment. 3 inverters running 24/7 wastes a lot of power but I have lots of PV power at the moment & LIFePO4 battery storage.

I have been investing in some better testing equipment. for the winter upgrades.

I do not see any one who has actually used one of these new AMG version 26,000 watt PowerJack power inverters yet!

I will pop the top when it arrives to see what is inside.

I plan to utilize the excess solar for heating my house off-grid.

I understand your dis-like for PowerJack over rating their inverters.

those are the wrong pictures. i tried to post but it is the 26000 watt one not the 12000 watt one in the pictures. i see where the confusion start now.

You MIGHT find a "SID LF Driver" in it.  But might not.  That's the extent of what you could expect to find, though--at least at this moment.

[pilgrimvalley]

I have an oscilloscope coming to see what can be learned. every inverter I have ordered seems to have a different transformer and this one is heavier than the 12,000 16,000 20,000 ones. so likely a heavier transformer, It just depends if they upgrade the guts or not for the higher potential output.

it is not a 12,000 watt version.

it is the 26,000 watt AMG version.

see inside in about 75 days or so, after the slow boat ride.

I am going to run 220 volt out of it into a  Hevi-Duty 7.5KVA General Purpose Transformer 240x480 primary 120x240 secondary Type HS stepdown transformer that weighs 136 pounds to see if I can purify it a bit either at 120 or 240. it is coming next week eBay special for 372 dollars.

the test is:  will the 26000 watt inverter work and do what continuously?

All electric off-grid is the end goal with some redundancy.

If you're hoping to clean up the flat-topped AC waves under load...this won't do the trick.  Problem is with the actual winding of the PJ main tranny, running out of headroom, and requiring saturated drive in order to maintain the desired output voltage.

Seriously doubt they "upgraded" the electronics at all.  Might have an ASL10 core in it...with not close to enough wire on it to meet the nameplate spec.

[pilgrimvalley]

the main entryway in my mountain getaway ranch  in Bolivia , South America. It is summer there. wish I was there but maybe in a couple months. they had to rebuild it to fit the wooden arc correctly. next week the 2 big doors will be installed. .... it is 220 volt single phase wire there now the last 3 years, before it was all built off-grid with some generator use periodically.

off topic i know

[dickson]

it is not a 12,000 watt version.

it is the 26,000 watt AMG version.       I  know you bought the  26000 watt AMG .   I  post the picture of the 12000 watt AMG to show how bad PJ  advertise on ebay .  I estimate that this  12kw AMG  will run less than  3000 watts continous .   3000 watts is what  my  old  8kw PJ  put out .    I do not know what your 26000 kw AMG  put out but it will  be a lot less the 13000kw .    Someone on this forum  run 8000 watts with ASL10  transformer  but do not how long before  it  overheat .  

[pilgrimvalley]

you would think they (PowerJack) would/could hire someone to type correct English in their ads on eBay. that part always amuses me (their wording in their ads).

I have an 6000, 8000 and 15000 watt inverters running continuously at low power draw at the moment 24/7. but electric off-grid in a larger output out on the farm is the goal. 

I will eventually run more power tools etc.

right now just low power draws off many LIFePO4 batteries.

[pilgrimvalley]

 96 280 Ah LIFePO4 cells and (8 more 5kWh LiPO4's so 40 kWh) plus 280Ahx3.2volt x96cells = 86016 Wh.

so roughly 126,000 Wh of batteries. for testing/ backup etc.

the inverter is the weakest link to the off-grid build still.

[TheButcher]

Wow, that's a lot of cells.  What's your ultimate goal in terms of wattage out of the AC supply?  Is the entire property going to be a single AC system or will there be different zones each with their own inverter?  I'm wondering about your DC side voltage vs expected AC side wattage.  13kW is about 270A at 48V (nom), without any losses accounted for.

[pilgrimvalley]

presently building a second larger solar power shed, ultimately it will power the whole property. solar generation is not the weak side either as i have plenty of solar PV panels. time is a big element as the weather slows me some as I do not have to work outside when the weather is bad, ( at least I choose to limit my exposure to the cold weather at the moment).

the PowerJack 20K and the PowerJack 26K AMG inverters will output a 2 hot wire 220 t0 240 volt similar to the utility grid 220 service I see in my Bolivia South America property. they have no neutral there either for their 220 volt electricity. but this off-grid build is being built in South Dakota, USA presently.

If I run it (the output from the inverter) into a transformer I can step it up or step it down and add the center tap neutral to clean up the power some. I have some Square D 100 amp 3 phase disconnect switches to utilize for safety purposes and use 400 amp class T fuses. the cheap switches some people try to use are not suited to high voltage/high amperage. 

I have a 3KVA and a 7.5KVA 240x480 to 120x240 step down transformers. they are about 95 percent efficient so will lose 5 percent there.

I also have some square D fusible disconnect switches for 60 amp and 30 amp to fuse/disconnect some loads.

I am building a larger shop to have an overhead lift for other repairs/tinkering. slow but sure....

yes there will be losses due to wiring and connections for sure, but the solar PV off-grid will last the next 30 year or more.

the solar panels have a 30 year life expectancy at which time they may only put out 80 percent. the LiFePO4 batteries have a 6000 cycle or about 15 year life expectancy where they will only have maybe an 80 percent storage capacity. the solar panels and batteries will continue to work at a lower efficiency. by then there will likely be an improved way to store electricity and better solar panels. at least one can hope so!

it is likely the inverters will die before then due to the capacitor failure or mosfet failures. 

most of the time I would not use 13000 Wh of battery pull as the solar panels and sun will be pushing electric into them. during the day when the sun is helping and when most of my work is being done the sun and PV panels will power everything. 

the inverter is still the weakest link. so at this time I have redundant inverters. not sure I would want to depend on only one in the deathly cold winter. I have wood but not set up safely to want to use it in my house(stock piling the wood for the shop and wood working projects). so electric is the route I am working toward for the off-grid solar project. I have an artesian well that runs 24/7 all by itself so water is not an issue.

gotta go. 😎

[pilgrimvalley]

on the DC side of things: I run 4/0 wires to the LF inverters from the LiFePo4 batteries. and use 400 amp class T fuses as the short circuit  inrush current from large LiFePO4 batteries can reach 20,000 amps AIC and not just anything will break that in case of a catastrophy (dumb dumb mistake).

see Lithium Solar you tube video about fuses.

a lot of so-called DC breakers are not capable of properly stopping a LiFePO4 battery surge and are a fire hazzard at best.

long story short is HRC fuses for the Lithium Iron Phosphate batteries (aka LiFePO4). do your research for a safe system.

I use the class T fuses and the class T fuse holders with cover. 

best bet is to consult your electrician about it, and or code official to be safe.

I don't know how Bolivia arranges things but odds on one of the incoming wires is the declared neutral and is tied to ground on the supply side, typically at the transformer that steps the HV distribution network down to the LV network.  There's many classes of supply systems out there, my supply is TNCS, so that may not be the case.

Indeed.  I made sure the breakers I purchased were spec'd for high amp break and gave some samples to an engineer friend to throw kA at them.  They did disconnect successfully but it turns out that they are still junk (see other posts I made on this forum).

[pilgrimvalley]

it is a 2 wire 220 system in Bolivia coming in. not sure if there is one of them tied to ground somewhere or not in Bolivia, but the overhead lines go for miles and miles on cement electrical poles. I never noticed any transformers any where out in the country in Bolivia. I will search it more next trip to the ranch. my ranch is about 2,5 miles wide and had e electric meters that we ( as in me) the owners had to buy and install.  i will seek a picture or 2.

I did see there are 4 wires on the overhead line going on down through the valley to other people but only 2 wires go to each electric meter hook up. i do think there is a transformer on the pole along the road where they installed 1 electric light. but only 2 wires to the meters to the houses. I did hear them talking about the light flicker may be due to having a light on the wrong wire so maybe that is due to it being on a possible neutral linked hot wire. I will ask the electical people next trip to my remote Bolivia mountain ranch. I am by no means an electrical expert or anything near it but I am researching to improve my DIY electrical set up off grid. 🤔 any help is always appreciated. 

[pilgrimvalley]

2 wire 220 in Bolivia, South America  --- painting the exterior a bit. it always dumb founded me a bit as i am used to 3 wire 220 240  and or 4 wire 220 240 in the USA using split phase in the USA.
