a 12k inverter at 48 volts pulls a lot of amps and heat through the battery cables.
a 15k would pull even more amps and require a much larger battery bank to run on cloudy days or at night...
12000 divided by 48 volts = 250 amps if the inverter was 100 percent efficient... which none are
at 90 percent efficient which is a reasonable efficiency to expect/hope for then the same 12000 watt inverter would need 13,333.33 watt draw from the 48 volt nominal LiFePO4 battery and the amp draw would be 277 amp draw and need a 400 amp class T fuse...and 4/0 copper cable between the battery and inverter....
four gs12 inverters at their max continuous advertised load would need 277 x 4 or 1108 amps from the battery....
real world efficiencies usually are less due to resistance in the connections etc....
they need to show amps being pulled from the battery bank at the same time various load levels are being energized from the inverters....that would be good to see real time in their YouTube videos!!!!
otherwise all hype...????
my BMS shows how many amps are pulled from the battery, I just need to measure the amps going out of the inverters some way on the AC lines (accurately)....
still need to study up on the transformers a bit more....
po4battery
the s....... power can connect 9 of the 6000 watt ones together but they cost about $1500 each.... posted july 13 there are 240 vac inverter that can parallel 2 for 3000 dollars . San Tan do not answer Sean because they now sell similar products . Parallel 9 inverters is 54000 watts . Where to get that big of a cable ?
San Tan solar is a lot bigger company with 2 large selling locations.... I bought 120 solar panel through them (((2pallets of 20 each at a time>>>cheap))) on eBay the freight was about $400 for 2 pallets (40 pv panels) maybe more today...they do not need the extra expense of an affiliate and are promoted by themselves...
they (San Tan Solar) do not have to have their potential customer prepay before the product is manufactured...no need to worry about powerjack-jack going on vacation...discover card refunded but powerjack-jack still has never replied to his rayjunglepower seller scam....????😢
the 54000 watt cable >>> that would be a big question for sure...and a likely big cable etc...????🤔🤔
most of them (newer parallelable LF inverters) have built-in mppt etc. now which could eliminate the expensive solar combiner box part at least some of them depending on the total size of the solar array etc....Sean said his big combiner box was something in the neighborhood of 600 dollars....for me>>> I just re-purposed high voltage electrical boxes bought cheap on eBay(50-80 dollars)...i think i learned that from alt-e....
looks like UL listing is coming or available for most of the LF inverter competition.....😎
i have been buying locally and online with free shipping to save on fuel costs as much as possible.....🤔
have a great Monday!
.discover card refunded but powerjack-jack still has never replied to his rayjunglepower seller scam....?
Did you get refunded for all your ebay orders or just one and still in dispute for others . I think PJ in China is the one who planned the scram on rayjunglepower ebay account . David still have 2 ebay accounts . You should get all your money back since this can be claim as fraud and has no time limit .
Sean said his big combiner box was something in the neighborhood of 600 dollars....for me>>> I just re-purposed high voltage electrical boxes bought cheap on eBay(50-80 dollars)...i think i learned that from alt-e....
I wonder why Sean not have as many solar panel as you . More solar panels mean more combiner boxes and copper wires is too expensive to run from the hill to the MPPT in the basement . I use plastic electrical boxes and plastic conduit from home depot .
they (San Tan Solar) do not have to have their potential customer prepay before the product is manufactured...no need to worry about powerjack-jack going on vacation.
I do the math . I charge with Discover credit at 20 percent to get help with charge back . The balance is 3000 dollars until I get delivery . The interest is 600 divided by 12 so one month interest is 50 dollars . Delivery is November so 4 month interest is 200 dollars . The interest for 5 month is more than the free shipping as UPS charge 150 dollars for shipping if I buy next year and not use the credit card . Some bank charge 29 percent so cost of waiting is even more . Most bank allow 60 days to dispute till delivery but the interest of 200 dollars is profit for the bank .
I use plastic electrical boxes and plastic conduit from home depot .
I like the metal boxes, I try to get primarily the outdoor rated ones, that way i can use inside or outside....
although the metal boxes are a bit more difficult to put new holes in,,,my feeling is they may contain any electrical boo boos if needed...
I also bought a electrical hole punch set as I learned that from my electrical friend some 30 years prior when I updated to a new electrical service main breaker box in one of my earlier electrical re-wire upgrade jobs...
out in the shop I use all metal conduit to keep the rodents and squirrels and raccoons from causing me misery...
always learning more and have been investing in better tools since way back when....definitely avoid most Chinese manufactured tools....I like Klein tools for electrical stuff and others...
I bought a 20 foot and a 40 foot tandem axle deck over trailers for $750 this week (so about $375 invested in each one)....plan to repurpose the 40 foot one to mount more solar panels on it...I think it will hold 20 to 40 panels at 45 degrees and make some shade for the hair sheep at the same time... darn hot and dry....
the 18k Sigineer's inverter fan is reported to be a lot quieter than the GroWatt....
wonder >>>> what the noise rating is on the specially made/ordered Chinese gs inverter fans??? how many decibels of noise....likely less than the el cheapo mppts....Sean is trying to block out /wall off >>>> the background noise they cause....
today is shopping day with family....have a great Friday all 😎
wonder >>>> what the noise rating is on the specially made/ordered Chinese gs inverter fans??? how many decibels of noise . Mine on max speed all the time and is 66 decibel and is louder than my generator at 60 decibel . Two fans sound like a jet engine . The youtube show Sean fan at 85 percent at 85 degree F in his basement and as loud as a jet engine . Four inverters will make the basement 100 degree and 8 fans at 100 percent and I imagine the sound of a 747 in the basement .

I'm researching that add-on lcd screen power jack sells, wondering if it will give me useful information, and noticed 3 different EBay vendors now. Maybe Ray Jungle Power's kids? My 2021 inverter is AMG split phase, but I have just one video connection labelled 110V. I wonder if the double one (110V, 220V) they call Thor's notebook could give me data on both voltages?

DO NOT BUY and waste your money . All the seller do what PJ in CHINA say . The FETs I bought and test on my work bench on a test inverter and some will blow up and LF driver also some will blow up and if that happen then all the good FETs will also blow up . I bought AWG 0 cable and at 120 degree F the aluminum crimp get hot and expand and the cable come loose and arcing cause my inverter to shut down last week . The insulation is actully on FIRE but away from the battery .

No, it won't work...notice in the listing pictures where they show the "Thor's Note Book", it has 2 cables going to 2 ports on the inverter. It's basically a rewiring of the 2 screens they used to have in the chassis.
The "double one" will show amperage on L1 ("220v"), and amperage on N ("110v"). This completely falls apart with a normal split-phase U.S. system...because "110v" loads on L2 will not be registered. And if you happen to have balanced 110v loads on L1-N and L2-N (i.e. refrigerator on one circuit, and a chest freezer on the other side), the "110v" meter will read 0 watts.

So, if I buy the 110V version, it will give me amperage info on the L1? (I already have an AC clamp meter) Does it also display fault codes for the inverter?
I have five aftermarket choke coils that I am going to experiment with on my AMG inverter.
From the EBay pictures, I gather that the official "Power Choke" coil is connected inline to the AC output, both the hot and neutral line. My aftermarket coils are 50uH 20A. If 2 are linked in parallel would the value then be 100uH 40A? The smallest official choke Power Jack offers is 65uH 220A.
I will start by testing 115V motors, but may progress to 230V motors powered by L1 and L2 and a common neutral wire. Would it be safe to connect one or more coils to each hot line and then the shared neutral? The biggest motor I will ever attempt to start is 1/2 hp (230V) that draws about 11 Amps at startup. The surge starting amps go through one hot line and the normal operating amos go through the other hot line.

...likely just N.

No. There is no connection between the external display and the CPU on the control board.

Parallel would double the current and halve the inductance. You would end up with 25uH 40A. https://www.allaboutcircuits.com/textbook/direct-current/chpt-15/series-and-parallel-inductors/
and https://www.translatorscafe.com/unit-converter/en-US/calculator/parallel-inductance/

So I have serious doubts that said inductors really serve any real purpose, apart from a marketing gimmick. At best, the only time they will do anything at all would be the very instant the motor is connected--which could be mid-cycle, and would be a "slam" on the wave. The inductors could theoretically therefore "absorb" some of that initial "slam."
But as far as starting power / total starting surge, etc., etc., they will not make one whit of a difference. The real issue is the poor FET gate drive in the PJ inverters.
If the motor has an LRA rating, that's basically the startup surge rating--as it starts from a dead stop. (LRA = locked rotor amps.)
