I ordered the cheap 12k from powerjack and got something else

It's runs fairly well but is very simple

I think it's a 4k max unit like the 8000W PJ unit.

The transformer has no tag on it but appears to be the same core as my other unit

It has 3 caps on the power board

The fets are RUH1H150R 100v 120A

That makes them capable of 50% more current than the RU7088R FETs in my 24v unit

Anyone know what I have here?

I am confused that  you ordered a 12000w PJ inverter  and was  sent a  Blue Energy  8000w  inveter  made by PJ .    This  has to be a custom  inverter  that  someone  return  to Walnut  .      The largest  is 3500w  by Blue Energy  on their wsb site .       The 8000w inverter  NOT AMG  will probably do 4000w and will not have a ASL2.0 transformer .

Hey, it would be nice if you would get your facts straight before just posting.

  • That's not a Blue Energy inverter.
  • Blue Energy is not made by PJ
  • It is not a custom inverter.  It's a newer AMG-series PJ rebranded with a different sticker on top.
  • The sticker doesn't even say Blue Energy.  It says Plus Energy WccSolar

Can't find much on Plus Energy WccSolar, but I did find this Spanish webpage, which clearly indicates that it's made by PJ: https://hiperchino.com/articulo/B079YW4JJZ/plusenergy-wccsolar-inverter

and of course, there's the "WccSolar" website, which the inverters are unabashedly relabeled PJs: https://www.wccsolar.net/product-page/inversor-solar-8000w-48v-onda-pura-cargador-120a?lang=en

I saw  Energy  and look up  Blue Energy   .     He was sent  a  8000w WccSolar  AMG  inverter .     Maybe it has a  ASL4.0  transformer  but  why no label ?     He can probably return  it  . and get  full refund  ?

It apparently has 3 capacitors, to my 2, and 120A mosfets

His   mainboard   with 3 capacitor  is probably   like the mini mainboard  in the 20kw  PJ and has 6 FETs on each  mosboard  ?        This  8000w WccSolar  may do  4000kw ?

The FETs are are different value, and can handle a higher wattage? Can additional capacitors be added by an end user to a PJ mainboard?

Your  mainboard can only have 2 capacitors  and 4  FETs  per mainboard  I think .     You can email Helen  for the  20kw mini mainboard with  6 FETs  and 4  capacitors .   The cost of  185 dollars   and maybe  more  now  for a complete  mainboard   is probably  not  what you want to do .

There are circles printed on the mainboard pcb that indicate where additional caps could go. You can see one in this photo. I think I have 4 banks of 6 FET's.  I don't know the value of them.

The mainboard  is the same one in  the  20kw  PJ  with 6 FETs  mosboard .        You can solder 2  more capacitors to the mainboard  .

Haven't tried it on the well pump but the better FETs it might I haven't tried it as I'm not sure I'm keeping it

If I keep it the top plate, center bolt  and rubber is coming off the transformer so it can get air flow

Runs my lights fridge tvs cooler and microwave without issue

Being  able to run the microwave about  3000 watts  is  probably  equal to  what a 12000watt  AMG PJ inverter  can  barely do .     IF  running a microwave and  fridge at the same time  is about  4000 watts  so  your  inverter is  better than most  AMG  .         IF it run a well pump  then  for sure  PJ  done something  good  .      Thank you for the information   as you have a  good  main board  and control board .

total 1650W.  Peanuts                      For new  microwave  and  fridge that  use less wattage  .

Mine  appliance  are  over 20 years old  and use more wattage .      I like to see the AMG 8000w  inverter  run a  well pump .

It was also running the cooler 1/2h but it beeped when the motor started

Had my Upower 10K running all the same loads without much issue 

Is there a notice on the inverter that advises buying a "power choke" to safely start motors?

I  would  return it because  the upower run without issue  and do not need a power choke .        Your  upower  should start a well  pump   so get  something  like  the upower .

The  notice for a power choke   show there is  a design  flaw in  starting  inductive load .

I've had appliances the same age...domestic microwaves simply don't run over 1,500W (max 1,650W) due to 120v circuit limitations.

And regular domestic refrigerators simply don't use over 150W continuous for the compressor.  Most of the time, they run under 120W.  There is absolutely no way a domestic 'fridge will use 1,000W continuous in normal operation.

 

@dicksonYou need to get your facts straight...all of your technical nonsense on the forums is getting quite annoying.
