Up Owe Her?

i have a 6000 watt one 24-volt LF PSW split phase. runnning it off of a 2P8S LifePO4 battery. 272Ah Lishen cells wired 2P8S so 544Ah battery. i notice the led 34 inch blinks but other things seem to run ok. it says it has P/N: LF ASL1-PSW 

then it says I/P: 0-115V/230AC

then it says 0/P: 0-18VAC

could not read more through the slot.

the booklet says U-POWER but it looks like the powerjack books but no girls on it.

use copper looking wire? Stainless steel case with absolutely no name on it. what size wire can i use on L1 L2 and neutral? will it do 3000 watts?

 i am going to wire it into a SquareD QO panel with SquareD QO breakers.

i have been using it for about 2 months just using the 2 outlets with powerstrips. low power so far but have used the heat shrink gun an solder iron etc heat lamp up to 1500 to 1700 watts. continuous use of maybe only 450 watts without any issues other than the led light does not always like it.

ASL1 🤨.  Gotta love U-Power's double rating of an already double or triple-rated PJ transformer.  Definitely won't do 3kw continuous.  Consider yourself extremely fortunate to get 2kw continuous output.

Let's see...18vAC * 1.414 (square root of 2) = 25.452v minimum required at no load for a pure sine output @ 230vAC output.  If you have it adjusted for 240vAC output, the ratio scales to 26.55vDC absolute minimum required for a pure sine output...

LED light doesn't like it...yup, that's the CPU regulator going into an oscillation, as it has no "zero" spot--it is either increasing or decreasing the output power.  Which forces an oscillation, visible in picky lights.  Shouldn't hurt anything, though.

using only 120 volt things right now. 

there may be more on the label on the wire attached to the transformer. i am only looking at that label through the ventilation slot. i did not open it up.

so you think only 2000 watts out of a 6000 watt 24-volt inverter. that is not very much.

the 24volt battery is LIFEPO4 and i have never seen it actually get less than 26.8Volts or so as the SBSM0 keeps it higher and i turn down the loads when it gets to 30 percent capacity on the battery.

i plan to maybe do a 4P8S LiFePO4 battery in the future using the LIshen 272Ah cells so it would be a 1088AHh battery.

thanks for any information.

It's a U-Power rebranded PJ (or just a straight PJ)...you will be doing well to get 2kw continuous.  The inverter is yet another hyperlabeled product, that's just what you expect from a PJ.  Genetry Solar inverters are sold for the true continuous output rating--they may look quite expensive to start with, but if you compare them to what you'd need to buy to get the same continuous output from the PJ lineup, the price is actually right about the same.

Sean actually reviewed a 12v 6000w PJ inverter.  You can see his conclusions here:

i watched it, it was a 12 volt inverter, i think he had 2700 2800 watts. is it the same transformer? just some less amps with 24 volt inverter....correct so it should run cooler? ASL1 in the 24-Volt 6000 watt LF PSW Split Phase is not the same transformer as his review.

i understand an outlet is only good for 1750 watts or less maybe only 1500 watts or less.

my question is what size wire would be good from the output terminals on the L1 and L2 ,N  to the SquareD QO breaker panel?

the SquareD panel is rated for 100 amps but 3000/120=25 amps if it only does 3000 watts.

any ideas?

Being a split-phase inverter (guessing from the one photo), you'll actually only have 12.5A max at 3kw 240v.  A single run of 10AWG wire should be plenty.

Believe it or not, the low-side winding of a PJ transformer is generally not the issue: it's the high side winding--which will be the same between your inverter and the one Sean tested.  With this in mind, battery voltage is sorta irrelevant for comparison purposes.

Yes, Sean had 2700-2800W out...but the inverter overheated and shut down with that load, it could not sustain it continuously.

lots of 10 awg pv wire to test it out.

the ac out terminal on this is small;  and i think it might do better mounted vertically so it would push the air flow up as the fan is in the back where the power from the battery connects. they dont give any real specification in the manual which barely even applies to this model.

any way to make it not flicker the led light? suggestion? maybe if more power load is larger would that help?

looks like 6 bolts (3 each side) would remove the lid.

yes it is a split phase low frequency pure sine wave inverter. 24 volt 6000 watt -- at least that is what it was sold as. here is 2 more pics of outside.

Not that you can do.  The CPU firmware needs updated to the GS redesigned code to stop the flicker.

I'm afraid Sid is being too kind to powerjack/upower regarding this "6kw" inverter.  The transformer in your inverter is at best a 1kw transformer.  That's the limiting factor.  With ideal conditions, a low ambient temp, and a strong fan running continuously, this inverter is still too weak to use for running your house.  Your 10awg wire to your breaker panel won't be the limiting factor, as your inverter will shut down way before you could warm up that wire.  Your refrigerator kicking on might be enough to shut it down.

This doesn't address the mismatched transformer wire sizes between L1 and L2.  If any of your heavier house loads happen to be on the L2 side, it might shut down even sooner.  240v loads are probably not possible for more than a minute or two, if at all.

If you plan to use this for only minimal loads it might be suitable for your needs, but keep an eye on it.  Wish I could be more favorable in my opinion, but I prefer truth.  Hey, maybe it will surprise us all and do fine.  If you plan to keep it hooked up to your breaker panel on a long term basis, please use some romex wire of at least 8awg, 6awg would be better.  PV wire is technically ok in your case but not ideal.

Best of luck!

yes the inverter is definitely the weak link. i have some 8 AWG i will use. not hooked into the house yet. using it all outside for the moment as i upgrade solar panel array.

the intent is to go all off grid in thefuture. i also have 24.volt inverters waiting on me to set up.

slow but sure DIY.

i have not had any problems EXCEPT the flicker in the led light (SMART ELECTRICIAN BRAND I BOUGHT FROM MENARDS).

I HAVE 10 250 watt PV solar panels connected up and  plans TO HOOK UP 14 MORE.

have to upgrade the inverter set up though.

the user manual is essentially useless on this 24-volt u-power powerjack rebranded  inverter --- no specifications that are real accurate.

 i will test the heat with infared thermometer. poco a poco----little by little.

thanks all. 😎

Sean got a couple things wrong on that video. The two outlets are both on the same leg of the transformer. Both go to L1 which is not direct from the transformer. L2 is direct and is only wired from transformer to fuse to L2 on the terminal strip. L1 goes to the main board from the transformer and gets filtered and the rest before going to the fuses on the bottom and then to the L1 terminal on the terminal strip. There it feeds two wires which go to the two receptacles. Should they have put one on each leg, yes. But that would also require them to filter L2 which they do not do.
