powerjack 24-volt 6000 watt lf psw sp amg version

Perfectly balanced as in same amp capacity on both legs or are they still up to the imbalanced trick?  ie, if you put a 15 amp load on both legs the voltage and waveform on both legs remains very similar?

That will require opening the inverter up to physically check and see if both output phases have the same number (and size) of strands...

It is a 6 wires  transformer in the AMG .    Option A  is  only 120vac  when  2  separate 120 windings  on the same core is  jumper in parallel .   It  is what  Powerjack do  at first many years ago  when they parallel 2  separate  transformers  .   The output  AC voltage  is exactly the same  on the 2 transformers to be balanced and the same  is done when parallel  2  separate windings on the same core .   If L1  is 119.1 volts  then  L2 is 119.1 volts .   There is no center tap  like my ASL9.0  when  L1  is  116 vac  and L2 is 106 vac and that is not  balanced  and  is a problem when wired  L1  N  L2  .    If  the  washer  is on  L2 then the motor  will  run hot .

Probably worded that badly, put a 15 amp load on leg 1, make observations, put the 15 amp load on leg 2, make observations.  If the transformer is imbalanced windings one side will see more droop under load than the other etc.

If the 15 amps loads are placed on the windings simultaneously the current will flow around the 240V circuit with little neutral wire current, if any as dictated by variations in the load, terminal resistance etc.

Is that the HMV dog, and why does it look like the dog is looking to the side and thinking 'Is it even safe to sit on this ting?'

 I was thinking the dog was thinking "Should I take a dump on it? "😁

made up inverter cables yesterday, hooked up the 24-voll 6000watt powerjack amg version lf sp psw to a 24 voolt prebuilt LiFePO4 battery and no smoke came out and the garage sale treble light worked (had not tried it before),

did not open it up but wonder what the AASSL 800 AMG - 1-10.4 means as far as the transformer inside goes.

usually that ells you the transformer installed....

any ideas? see picture above. 

So what is the latest on it? What was the transformer?

 

When I bought my U-Power units they said from California but the units were actually shipped direct from China. And interestingly, came by air instead of ship.

I will have to open one up to see the inverter inside. no one replied that they knew what inverter was inside so i guess i will have to dissect one of them.

The latest  youtube  say Sean is repairing  Powerjack inverter  again .   Maybe he will do a review  on the AMG  powerjack  and the rev 11.1  control board .

Sid say this forum is not closing  at the end of November .

Question: After I completely disconnect house to the city grid (safely, using Interlock kit), can I connect the Inverter's L1 to house panel's L1, inverter's L2 to panel's L2, inverter N1/N2 to panel's Neutral bar?? If the inverter is truly SINGLE TRANSFORMER WITH CENTER TAP of secondary coil as the neutral, then theoretically I could. I just don't know how the inverter get 220V, via one or two transformers. If 2 transformers, then I cannot connect to panel as the inverter is not truly split phase. Thanks

 just don't know how the inverter get 220V, via one or two transformers.           Jumper 2 to 3  for 220vac  .   Ho advise for connection to house  as this inverter is for off-gtid or RV  or car .

Yes.

The inverter has a true split-phase output, with a single transformer.

To split hairs, technically the output of the inverter consists of 2 secondary windings.  Put them in parallel for full output @ 120v.  And put them in series for full output @ 240v, with the "center connection" being Neutral.

And even if they were two physically separate transformers, as long as they're phase-locked to each other (i.e. run from the same source and/or synced to the same source), that would also work just fine for powering a split-phase load.
