Have you been able to measure the no-load power consumption of the inverter?
when the inverter is turned off the clamp meter reads from .19 to .21 amps; when the inverter was turned on the tacklife digital clamp meter reads 2.1 to 2.13 amps with the coffee pot plugged in to the inverter (but the coffee pot is not turned on but it powers up the digital lcd screen on the Hamilton Beach coffee pot). I still have not observed the readings on Thor's Note Book with the 2 lcd screens. I will have to get it mounted up at eye level someplace.
the tacklife digital multimeter clamp meter is clamped accross the negative 4/0 cable between the inverter and the 24 volt prebuilt 5 kwh battery from tech direct. this is for testing while i assemble the larger 32 cell Lishen 272Ah battery.
is the above what you are asking about the no-load power consumption?
on the positive side it reads 1.75 negative amps between the lifepo4 battery and the inverter. so to me that indicates i should be taking the measurement on the negative cable as that is the flow direction of the electrons???
the voltage meter on the prebuilt 24-volt tech direct battery reads 26.7 volts at the moment but i do not know or believe that is totally accurate.
the tacklife meter is an ac/dc clamp meter auto range 4000 counts.

2A no load...not bad I have to say. Not sure I understand the 0.2A when turned off...that sounds like a DC clamp meter that isn't properly zeroed. If the cooling fans aren't running, the off current should be closer to 0.02A

it does have a zero button i will try to zero it again
when i zero the clamp meter it says 1.96 amps.
when i unplug the coffee pot it reads 1.88 amps so the lcd screen on the coffee pot burns .08 amps when plugged in but no yet turned on.
s
when the inverter is turned off it still draws.07 to .09 amps. there are no fans running but this is probably the no load consumption with the inverter attached to the LIFePO4 battry but turned off.
when the inverter is turned on it reads 1.89 to 1.91 amps using the tacklife clamp on meter on the negative 4/0 copper cable between the inverter and the LiFePO4 tech direct pre-built battery. there is nothing attached at all on the load side but you can hear the terroidal transformer humming......
the tech direct 5 kwh battery has a 130 amp built-in BMS and circuit breaker. so right now i do not have a class T fuse installed; but will have when i hook it up to the 32 cell Lishen battetry i am assembling.
2 pics coming. dont mind the mess!
wonder what is the purpose of the analog volt meter. it does not read 24 volt or 26 volt or anyhting that matches up to the LiFePO4 battery i have hooked to it. my lifepo4 battery is at 26.7 volts, but this analog volt meter on the transformer box only reads about 18!!
when you switch it to power sav on the switch it repeatedly bounces up to 10 on the analog volt meter. there is absolutely nithing plugged in to it right now. i am making cables for the larger lifepo4 battery and neede to move it. so unplugged the loads and hooked to the 6000 watt inverter.
transformer box only reads about 18
That is the correct input ac voltage for the 24v ASL6.5 transformer . My 48v ASL9.0 transformer read 36vac for input . Your LF driver is working good .

Correct reading . Your inverter is good and the ASL6.5 transformer is good .
on ebay they now have some strange inverters with 4 wires to the output side AMG version. wonder what that is about?
26000 watt one and a couple other sizes?
260A at 48V for the *cough* 12.5kW continuous output and 520A for *cough* 25kW peak output. Even more ludicrously high currents for voltage models with similar *cough* wattages.
At a guess they probably had trouble with the cable attachment points turning into glowplugs.

Might be taking a playbook from the GS transformer winding spec and such for that, haha (note the comments about "Also the same coil we put more wires on the transformer about 1.5 times than before")...
With the "AMG" setup, PJ is making an inverter that you can theoretically reconfigure between 120v single phase and 240v split phase output by rewiring a couple of jumpers on the 4 position connector. In essence, you have 2 120v secondaries of the transformer that can be wired in parallel for single-phase, and put in series for split-phase. Actually not a bad idea.
The catch is that any and all voltage regulation takes place at 120v (which actually is quite common in PJ inverters); if you load down the "240v output", the inverter will not correct for the sag on the unregulated secondary. If that's not a problem, these inverters might do quite well for you.

Wiring option A for 120vac only L1 N 1 and L2 N2 but no 240vac and can not L1 N L2 or bad thing will happen . Wiring option B for 240vac direct wiring to 240vac inductive load such as air compressor or well pump . Can also be wire L1 N L2 for pure split phase 240vac but make sure load on L1 and L2 are the same or bad thing will happen Bad is like FET blew up and the main board catch on fire . I think your ASL6.5 transformer is balance L1 is 120vac and L2 is 120vac so wiring L1 N l2 will work ok . Many powerjack transformer is not balance like ASL9.0 where L1 is 115vac and L2 is 105vac so I wire direct L1 and L2 for 240vac and has to be careful wiring L1 N L2 and watch the load . .
Gad, misread that completely. If only I could edit my earlier post. Sorry!

Should be able to...just click the 3 dots by the top right of the post, you should have Edit among other options as well.
lots of inflated abilities in the amg version possibly/likely. if they did 50 percent of advertised without burning up that would be good.
i just thought it was interesting but a bit confusing at the same time.
it seems they are selling or at least offering for sale less of their older style inverters. but they get more confusing in their wiring.
it is interesting but these larger inverters with heavier transformers put out a lot of heat so i think the separate transformer box with its own fan is a plus as well as the 2 fans for the separate control box that the 15000 watt lf sp psw 24-volt 3 box inverter with the asl 6.5 transformer may have been a good move. not much warranty as i will never ship it to be repaired if necessary --- too heavy.
had a thunderstorm with lots of wind saturday night >>> not an issue with off-grid but some grid tie stuff lost power.
slow but sure i will get more off-grid up and running.
waiting on some heat shrink for the 28 2/0 battery interconnects at the moment ....maybe here wednesday! 😎
thanks for all the comments!
