Here's some more grist for the mill. With these AMG inverters, we're being told they need AC choke coils to safelt start motors, and three different ones are for sale by the EBay seller. The uF values seem to relate to the watts that you draw, and they seem to market them as 110V accessories. I hope to use my inverter in the 220V mode, so I might need 2 of them. I see similar chokes on AliExpress for much less money.
Now after 3 years I know why my ASL9.0 transformer has 2 times more winding on L1 than L2 and L2 ac output is 10 vac less than L! and is unbalance .
my 15000 watt non-AMG had the same output on both L1 and L2 but the voltage was a bit lower than i wanted.... i forget now the exact numbers but not quite 240 maybe only 230 volts....I have it direct wired to the AC breaker panel...
never opened it up to see the transformer.... so do not know the ASL version on it or anything and it is on a shelf in a rather inconvenient place.... i had to get my friend to help me hoist it up there....
i have some hope for the 26000 watt AMG PowerJack LF PSW SP 48-volt inverters to function still..
I have no hope for any of the AMG inverter . It won't start a 240V 1/2 hp pump, but I haven't given up. It also initially wouldn't start a 115V 750W refrigerator, but I discovered a trick, and now it starts and runs it fine. I'll do the best with it that I can . Yes I know that there are ways to help the AMG to atart inductive load by doing what you did . That what I like about PJ inverter is tinkering an see what happen . I will do more tinkering but not now as I do not trust PJ parts .

You have a good 3 boxes 15 kw and not AMG . Your transformer is the good ASL6.5 and I thought the transformer gauge read 18vac from your pictures aug 2021 . The ac voltage can be adjusted and the low battery voltage can be adjusted . This transformer has L1 and L2 exactly the same and balanced .

Thanks Dickson, >>>> yes, that is the picture of my non AMG 15000 watt PowerJack LF PSW SP inverter >>>>I now have it on a higher shelf, the 3 box design...and hooked up to the AC breaker panel in split phase....
yes, the analog transformer gauge is on the back side of the transformer so now that it is on the higher elevation shelf, that would also be essentially impossible to read with out some mirrors or something...
if I was to to it over,,,,I think I would still have it up high but maybe in a larger building in the center so one could more readily get to both sides....it was a trick hooking up the 4/0 copper inverter cables on the back side of it next to the wall...🤔
I still need to try to turn up the AC voltage output a tad.... and look at the battery input voltage adjustment also...
just spent 3 days building fence and still doing more fencing to keep the critters in....😎
I like this inverter but was never able to get a second one at a low price....they want 1500 dollars for this one if you could still get one.... but I do like this PowerJack non AMG 15000 watt inverter.....😎 it cost $815.10 including tax and delivery,,,a bargain price at auction.🤔😎 I never turn it off....
25 kw inverter and 20 kw inverter in aqua green floor model higher voltage inverter might be a good option also...
the sandi 25kw inverter was $7500 dollars including shipping but it runs at a high voltage 240 volt dc battery and the dc to ac inverter is said to be efficient...and UL listed
but 240 volt dc battery would be a bit more scary/dangerous and the high voltage mppt would be another system re-design... so lots of changes to go with the high voltage split phase sandi inverter...
interesting but I still need more hands on experience or hire the electrician for high voltage..
the tesla is said to run on 400 volt and higher voltage is the trend for new car battery systems...
not exactly a DIY system,,, at least above my comfort zone....🤔

not exactly a DIY system,,, at least above my comfort zone.. IF I had a TESLA powerwall I can easily make the sandi 20kw inverter run a big house 24/7 off-grid . Look at the spec and the 2 is a perfect match I think . .

1 hour ago, dickson said:IF I had a TESLA powerwall I can easily make the sandi 20kw inverter run a big house 24/7 off-grid . Look at the spec and the 2 is a perfect match I think . .
the beauty of the large high voltage battery and high voltage inverter and the large high voltage mppt charge controller is no combiner box and you just connect the solar PV panels together via the MP4 standard connections and run high voltage to the high voltage MPPT.... no longer need a bunch of small make sky blue /mr power cheapo mppt solar charge controllers.... but a definite higher voltage different design components which are UL listed so that would be a plus to the high voltage system....and to passing electrical code inspections.....the 25kw sandi inverter I think his video said it weigh about 450 pounds if I remember correctly.....
I have 4 expensive (about 550 dollars each) outback flexmax 80 solar charge controllers and one of the high voltage MPPT would have eliminated that issue/expense so it is definitely an interesting idea....make sky blue MPPT solar charge controller will only power a small array so you need a lot of them...and they have been increasing their prices also...
evidently the Sandi company also makes the high voltage batteries with BMS etc in the rack type version so that also is UL listed and plug and play to some extent.... he recommends a 100kw LifePo4 battery...and you can connect to the grid pass through as a second backup if one wanted,,,,they have wifi, and other communication if one desired....
to get along with the electrical authorities UL is almost a requirement for anything of any real size especially if it connects to the grid.... outlaw systems must be totally off-grid.
could be an option for my 96 cell 327 watt solar PV panels....budget is a bit against me now though...,,,but I could try to sell the powerjack equipment and go high voltage.....hmmmm????
very interesting in comparison to 48 volt systems.... for sure...
tesla powerwall is the cadillac today >>> high end .....
UL listed so that would be a plus to the high voltage system....and to passing electrical code inspections.....the 25kw sandi inverter I think his video said it weigh about 450 pounds if I remember correctly..
IF they do free shipping and no need for expensive MPPT then I think the 25kw sandi inverter would be about the same price for two GS 12 inverter in patallel . I can keep my PJ 15 kw inverter to use during the day and switch to the Sandi inverter at night using Tesla powerwall and never run out of battery power . very interesting in comparison to 48 volt systems.... for sure..
Victron originates in The Netherlands.
Canada. 🤣

High Voltage Sandi 24k 240volt or more>>> LF copper based PSW SP inverter: I think in his video the 7500 dollars was the delivered price for the 450 pound 25k high voltage Sandi inverter, getting rid of all the small solar charge controllers and combiner boxes and other expensive wiring do dads would simplify the woes of 24 and 48 volt based off-grid whole house solar PV systems but it could be connected as a pass through so also could use the grid a a standby....
two bit davinci YouTube video was making a good point of not wanting WIFI on all his stuff.... I like WIFI and then sometimes it does not function (at which time i hate wifi) and it makes your connection more easily hackable....i like hard wire internet as it is faster and more dependable....
my system does not require 24/7 WIFI monitoring.... it just works.... I like the WIFI on the BMS but rarely use or look at it...
for me I still want the strictly off-grid electric systems and avoid as much of the utilities' monopoly as I can....
I had a business called the "animal factory" (my pet shop in college - primarily tropical fish and 140 aquariums, birds, and small critters) where I bucked the government attempt to control what I did out of the basement of my private residence and made the front page of the Des Moines register maybe back in 1982-3 or so.... it is called stick it up your XXX mentality; kind of like my constitutional right in our free country.......sorry I digress. Rural country life for me please
kind of like the utility company coming around when I was gone asking for work to connect to their system.... this is strictly off grid PV solar at the farm in rural South Dakota.... hmmm
high voltage systems with high voltage inverter and a single high voltage mppt charge controller is an interesting idea and may be the future way even though it has been around for more than 10 years,,, just an overlooked and under publicized likely due to the more dangerous high voltage...but they are making them more plug and play.... very interesting for sure...🤔🤔🤔
innovation is the key to our future... not stagnation.... so I definitely root for the small innovators vs monopolies subsidized by the man....😎
my system does not require 24/7 WIFI monitoring... it just works.. for me I still want the strictly off-grid electric systems and avoid as much of the utilities' monopoly as I can.. My PJ inverter has no Wifi and must be monitor manually to make sure the battery do not go over 68 v and overheat and blow up at 400 degree F . I monitor the battery for low voltage 50 v by the LED flickering in the house and that works everytime . I can not avoid the monopoly as the utility has smart meter which I must pay 40 dollars even if off-grid 24/7 .
kind of like the utility company coming around when I was gone asking for work to connect to their system... This happen many times in the city where the renter grow mj or weed will steal power from the utility underground cable but the smart meter tell the utility to send a helicopter with infrared camera at night and then go and raid the house because the meter show no usage . .

At that time I live in Iowa and raise and breed all kind of tropical fish and gold fish just for fun . I also get the Des Moines register everyday and probably seem it ,

Just FYI....the Tesla Powerwall does NOT use a high-voltage battery internally.
It's uses a 48v battery internally (IIRC). With a bidirectional voltage converter that steps it up to "350-450v" (notice that's a very generic range given, not specific)--and of course, this results in lost power when charging and when discharging (efficiency in everything).
Notice the specs on the Tesla Powerwall--the continuous output is significantly LESS than 1C. (Powerwall 2 stores 13.5kwh, but maximum continuous output is ~6.7kw, or 0.5C.) This means that in order to simply get a 20kw continuous output from the batteries, you would need a minimum of 3 "Powerwall 2" units (= 20 / 6.7)--at over $7,500 each (prices online quoted vary from $7,500 to $11,000; I've never bought one).
Plus a $7,500 inverter. And nobody knows how much the MPPT costs (yes, you will need one for best performance).
Seems to me that there's a slight cost difference here between DIY PJ and highbrow name-brand stuff 😉.

Tesla will not sell Powerwall for DIY . Must be sold and install by Tesla dealer using their inverter and solar panels . 400v DC is too dangerous to build a DIY powerwall .
