Split Hairs and yet no washing cloths yet again.


Recommended Posts

I think I found a bug?  I'm washing dishes on one of the split phase slave, and then I try running my washer and well, trust me its not running, when its spitting water then jerk, then spit water, then jerk over and over while trying to fill up, and I took and throw it on grid it works fine. so Uhm, Sid.  Help?

We'll sort this out over PM.  Your washing machine seems to be a very particular machine; I have a very hard time believing it would run on a PJ inverter without complaints.  Only thing left I can think of would be that it's complaining about 0.3Hz off on the AC output--which is highly unlikely.  Or a grounding issue, if it's concerned with that...

I   can never  run my  PJ  inverters  on washing machine  .   The  washing machine  cause  a huge  ac spike  and  surge  to the inverter .    Strange  my 12v  AS4L  8000 watt PJ inverter  will  start  a  5 hp commpressor   wired directly   240 vac  .

Well my PJ 12v 8k had no issue doing what I'm doing to the two GS.  All I know the washer is clicking ona nd off as if the power is turning on and off, yet the meter shows that it staying normal, only thing I can think of is that the slave has not been calbrated and while its running the dish washer its cause the master to get confused because the phase is off.

Not possible.  Washing machine connected to the master inverter...there is NO power transfer between the master and slave inverters in a split-sync setup.  The slave inverter is using the connections to the master inverter solely for a sync signal.  With the current wiring/system setup, the "master" inverter is completely and totally blind to the existence of the slave inverter.

I really have no idea why your washing machine will happily run on a PJ inverter--which has terrible voltage regulation by comparison (3v steps), complete with constant regulation oscillations...but is complaining with a GS inverter (~0.15v steps), which is capable of holding a perfectly stable AC output (with a stable load).  If it's complaining about a not-so-perfect sine wave, a PJ inverter will start to flatten out WAY sooner than a GS inverter, due to the transformer specifications.

The only possibility then could be AC output frequency.  Again, if it's going to throw a tantrum at less than 0.5Hz difference--goodness sakes, I don't know what to say.  We obviously can calibrate the GS inverter's AC output frequency, but...

What is your washing machine's make/model?  Maybe there's a clue in the manual.

Like I've said: I have a Maytag Bravos XL washing machine--a direct drive HE washer.  Never had a drop of trouble with it on my GS house inverter.

all I know its a maytag, I bought it about 4 or 5 years ago.  I did yesturday get it to stop clicking on and off, and then started filling up like it should, but then while it was going back and forth washing the motor kept getting louder and louder, so I just unplugged it, I don't want my washing to  kill over.

Okay, I try it with the slave, well, it having the same issue, plug the washer to the gird runs normal smooth and no issue.   So basicly for some odd reason my washer will not run on those gs inverter. . .   I must got one odd ball washer to hate what ever is going on, to make it click ona nd off over and over, then work for a few mins then stop and not want to do anything, just like now, I had the slave empty the tub, then while it was doing the clicking on and off, on and off, finally got it to start filling the tub, then it got so far and just stop, woudn't finish filling up the tub at all, waited five mins and nothing, so unplug then plug into wall and it started filling the rest of the way and started washing with out no histation or makeing the motor get louder and louder and louder.  Beats me, I don't know, all I know is its not working on the inverters, and filling up the tub should only take 13watts? geesh.

I have no idea what the washing machine is complaining about.  The part that stymies me is that it reportedly runs fine on a PJ inverter.  There has to be some really weird problem causing it to go haywire...and it could maybe be grounding.

Maybe try connecting the ground wire from your outlet to the inverter chassis (there's a screw for that purpose near the output terminal block).

Did that, now the dang washer will not come on when I hit start, waited five mins for it to do anything, plug it in the wall grid and press the button one time and it comes on. 

Wellllll...we're getting closer then.  Must be something it doesn't like about the grounding.  Which would make a heap more sense than either voltage or frequency.

But if it's this persnickety, how in the world it runs on a PJ inverter is beyond me.  There must be a major piece of information missing here...

It ran on the 12v 8k with no issue, the only thi ng was the PJ you could hear the coil hum and I'm running exactly the same stuff I ran on the PJ on these two GS.  and the pj was wired to the breaker box I have in the same room, not the main box and the same outlet that I got the washer ocming from is the same one I had going to the breaker box just this time directly from the gs.  Also when I ran it on the slave inverter it does the same thing and thats through the 100foot extention cord.  the freezer, dish washer frig and everything else I thrown at them is working fine as far as I can tell.  I've not hooked up the microwave to it yet, will try that now, I got a amazon microwave that talks to my echo, so if it don't work then there is a problem. . .

I'm not one to throw up my hands and quit...but unfortunately, I am not aware what the washing machine is complaining about.

It could possibly be frequency; I saw the frequency trim on your inverter was set to 60.33Hz.  But most appliances (especially the direct-drive washing machines of today) can handle 40-70Hz input range...if not beyond.

If we knew the model of the washer. It might have an internal GFCI detection for safety that automatically resets when it sees the fault is cleared and some sort of interference is messing with it but I would expect a PJ to do similar.

I'm trying to figure out how in the world the washer accepts a PJ inverter, but is choking on a GS inverter.  Seems grounding is a bit of a clue...

Grounding on a PJ inverter is capacitor coupled from L1 - N (failing UL code which requires ground to be floated between the largest potentials, i.e. L1 - L2).  Rev. B GS board (which @The Blind Wolf has) uses a single decoupling cap from Neutral to ground.  The PJ inverter also probably has an extra filter cap (2x 4.7uF) on the L1-N circuit (i.e. the single outlet) and of course no filter cap on the L2-N circuit.  The GS inverter has a single 4.7uF filter cap across each phase. 

One of those mysteries.  Sean had compatibility issues with an Amana washer, but ended up replacing it before we figured out the issue.

Well, I have to have a video call, and tell me where to look for the model and read it.  I don't have Sid contact so i can't call him lol.

 

I'm planning on having the two hooked up to the mai n by this weekend. was hopeing to resolve what going on, and the slave needs to be calabrated anyhow before I throw it up as its reading wrong on the web page.
