Unable to wash clothes with my GS.

Sounds like this topic changed a bit, but I find the battery comparison interesting.  The cool part of the discharge curve of the two battery chemistries makes them super handy to complement each other.  So when Lithium falls on its butt AGM kicks in, especially at colder temperatures.   My AGMs work as a backup when the Lithium hit the last 20%.  I put the AGMs in there and they take the load on at about 12.8 volts.  I have a voltage alarm set and there is plenty of battery capacity from my AGM battery to start up the generator.  Now as everyone says don't do what I do.  I did it out of necessity and well its been working good now so may just leave it alone.  I used to have a backup relay to do the same thing, but a cable went bad one day and I just ran it direct and now may not put it back. 

Sounds like you have a standby use case, which is workable since the LA will have sufficient time to fully charge. 🙂

 My AGMs work as a backup when the Lithium hit the last 20%.  I put the AGMs in there and they take the load on at about 12.8 volts.

I  switch  the AGM to take the load when the lithium  battery drop to 13.8 volt .  The inverter shut down when the AGM drop to 11.1 volts .     Four  AGM at 13.8 volt in series is 55.2 volts .   Four AGM in series at 11.1 volt is  44.4 volt  at shutdown .   

Yup. Dead on! If the LA gets no use, i am a happy camper. It's there for 3 reasons: to handle loads > the maximum capability of the BSMs (in my case, 1C = 400A), provide power for generator startup, and finally [and most importantly] to act as a sacrificial lamb for the alternator should a BSM disconnect. Beyond that, the shunt reading approaches 0 for the LA bank.

No argument from me, friend. I'm dealing with a very specific use case. You wouldn't want to rely on the LI charging the LA if the LA is allowed to get significantly drained. Though it would eventually charge it, since 12.9 (LFP @ 20%) > 12.7 (nominal LA) - presuming the LI bank is adequately large, and given infinity time.
But that's not my use case. I argue only against the condemnation of the practice, not to encourage the practice.

I really didn't intend to start a chemistry war. lol. I just think it's important that we not dismiss a practice out-of-hand. You'd be amazed at the diversity of use cases out there.

*cough* I do entend to use agm on the master on its own make sky blue charger, and lythuim on the other with its own sky blue.  Simply because getting enough of the lythuim premade batts is costly for me at the moment.  and most of mine are DIY battts. currecntly I have one 200ah and 1 100ah battle born batt, all the others are, either 31650, primatic or headway batts.  the ones I'm having issue with are the 31650, they seem to have the most issue when place under too big of a load, and I was trying to run two invets 600amp 24v with all of them, and it was causeing too much pull, so right now I got the master running off of AGM/Flood banks and Going to have the slave running off of the others, that way the draw is small and less likely to cause a problem.  If I'm running myu whole house I don't use that much power I be even lucky to even hit 3k total.  Only time I really need the power is when I either need hot water, or dryier, and I stay away from the whole house heater as it pulls 10k on its own, so I use 120 infered heaters. which pulls the same amount as my counter top oven, and induction cook top, I kick the main stove out the door.

I want to get ther water heater replace with a heat pump model and the dryer but thats down the road. 

You didn't start one.

I'm not amazed at the use cases.  In fact I even stated there are solutions out there.

I'd be more amazed if someone spouting pairing a LA and Li battery would, for once, actually state they have a very narrow and specific use case and actually state that use case up front before the entire discussion kicks off.

I think this was a nice discussion, good to know there are others trying stuff out of the norm.  I love testing and tinkering and learning.

While we still talking about batts. I do have a question that has stomp me and I'v enot found anything saying either way.

If you got two 12v 100ah batts that can each out put 100amp max, and you wire them as 24v, does that mean you still only can output 100am max or 200 amp max?  I now the 100ah stays at 100ah but the volt changes does the amprage changes as well is the question.

Series batteries: amperage remains the same, voltage doubles.

Parallel batteries: amperage doubles, voltage remains the same.

If you got two 12v 100ah batts that can each out put 100amp max, and you wire them as 24v, does that mean you still only can output 100am max or 200 amp max?

100ah time 12v give 1200 watthour and two in series give 2400 wh  and 2 in parallel give 2400 wh .  If you wire as 24v your output is 100 amp equal 2400 wh .   If you wire as 12v then in parallel the output is 200 amp equal 2400 wh . 

So if I take my six 12v agm/lead batt, and put 3 in P with 3/2s would that mean I can pull 300 amps makeing it a single 300ah 300amp 24v?  since right now I got them wired with 2p2 with three sets? going to a bus bar to the inverter?

Just ran a 1200 watt test for 15 mins cooking a pizza, on the master with no issue, checked the batts, and they were all reading 12.4v while under a 53a load.  Not bad. the inverter only came on once with the fans, considering that my heater is running the house right now, so the temp is higher the normal in that room.  Going to push it to 2500 nex, useing the breaker, switching off the 240 loads and only running one leg, so that way I can cook a chicken breast and run the washer and anything else like my network to see how it handles, no issue with the wireing so far. better not be considering how big of wires I got on it now lol.

So if I take my six 12v agm/lead batt, and put 3 in P

Two 12v in series  make 24v  and  100 amp .    Three 24v  in parallel  to the bus bar  make  300 amps  and 7200 watt hour .   GS 6kw is 250 amp  so   2500w max is 105 amp .

Six AGM battery  should  work  for  300 amp load  with you wires .     

Well, I ran the test, seems to be a issue with the low end of the gs inverter to run the washer by it self, however, while running my counter top ovan still going as we speak for another 2 and half hour of cooking, anyhow, I ran the washer, and it ran normal through all of its cycles, I wached the gs hit up to 81 amps at 24.3v for a few seconds before it drop when the washer went to spin up.  Other then that its running great with no issue, and all my wireing is cold as it can be, 66f ambance with 100.9 trans the fans come ona dand off highest I seen hit is at 32% then drop to off.  Luckly its sunny today and doing this while the sun is out and the bank was basicly fully charge at 28v when I started.

So I'm guessing the master is fine, and once I bring the slave up will put more of a load on it.  I'm guessing the highest it hitting is 3500w right now with running the two items. 

FWIW the suggestion of running a resistive load in conjunction with the washer to give the inverter something more to chew on came from the Victron community forum where someone was having the same problem with a Victron inverter.

Pretty sure then that this has to do with insufficient AC output filtration on the inverters.  The more the filtration, the higher the no-load current...but if there's not enough filtration, picky appliances won't run.

If you can find some 4.7uF (or 10uF) AC-rated caps (thought you ordered some) and put them across the AC output of each inverter, it will increase your no-load current slightly--but the washer should hopefully stop complaining.
