You can't beat Sigineer low frequency, transformer based inverter chargers for performance and reliability. They're so much better than all of the cheap, short lived, high frequency junk inverters that everyone else is selling.

Glad to see you making videos again

The insides look just like the AIMS inverters. That empty space on the AIMS was for some kind Pump input hookup inductor.

Interesting things about you say about the fans, motor on the back is the direction of flow (even the shape of the thins) , So this is a split phase 7kw per leg inverter (don't expect it to do 15kw off one leg without melting stuff) I seen others wire directly off the circuit breaker instead of the junction blocks so not to overheat

Those are DIN rail breakers and are much more common than what North America uses in our walls. They are the standard for all equipment and machines, as well as ROW electrical panels.

4Awg is rated for 135amps when used as chassis wire like it is there. When used as a chassis wire it's current rating is higher than for use as a power transmission wire. Because it's used in open air it will dissipate heat more efficiently.

Can you detail about the common issues with the inverter board? Looks just like the inverter board in my 18k SunGoldPower that just spectacularly released the magic smoke.

Kindly assist with the no load current draw. i.e how much power does it draw without load. Thanks.

Wow , thanks man

Nice video Joel (from one to another). Can you tell me how loud the unit is when operating? Both low and high load? I am very curious about the noise level.

Can you hook it to an oscope to show waveform under load? My Powerjack claims 15kw constant load but anything above about 5kw and it goes to a flat-top (almost square) wave.

The empty space is probably so they can use the same case for the 24v models with two driver boards?

At 15kw using 48 volt battery voltage, you'd need the batteries to provide 312 amps. Which means you'd need a whole heck of a lot of battery. (312 amps x 48 volts = approx 15,000). Which means you'd need at least 350 awg wire to conduct that amperage. 350 awg is nearly an inch in diameter. So in essence 15 kw inverter is for industrial use and not intended for home usage. Not sure you realize any of this. At today's prices the wire alone will cost as much as the inverter. Most homes will run fine on 5 kw or less, depending on devices used. If you are off grid you will probably want a gas or propane hot water heater and stove as well as clothes dryer if you need or want those items. I can run my entire home for around 2200 watts including 4 heat pumps (inverter type). Bigger isn't always better. Unused inverter will be less efficient than smaller one being fully used. I cannot imagine the price of batteries you'd need to fully use this beast but it's got to be near $10,000 range using build it yourself components.

What is the name of the inverter and how many volts is it for?

How is your 10k inverter? How does the review work? Or is your Chinese stronger?

this can power up my entire workshop all at once!!

That big empty space is where you put the 6 pack of beer when you poke around inside the unit.

I wish they made inverter/chargers that could be phased locked together, so that instead of 1 large inverter/charger like this, you could have 2 smaller ones each feeding a separate 120V branch, but phased locked 180 degrees so that the 240V stuff would work well too. So for example, a pair of 7.5 KW inverter/chargers instead of a single 15KW inverter/charger. I suspect it can be done so why don't they do it? It would be easier to move 2 smaller inverters around, and they could either share a large battery bank or have their own smaller battery banks. Many more options with that setup.

wow. I like transformers

Where did you buy it from

you need to flip out thoses single breakers for a single double breaker. its very bad if 1 triples as in the usa or canada we use 2 legs of 120v aka 120/240 split phase. double single breakers tap on leg 1 and leg 2 to get 240v. each leg is still separate of 120v when running back to the appliance. so if 1 pops you need both to trip or you can burn out your appliances. can even cause your appliance to back feed from a simple trip and burn out your inverter but save your appliance.... or burn both up... My guess the inverter will fail first

The Sigineer lineup looks a lot like AIMS which is made by YIY as far as I've read. May be useful if you are trying to track down parts.

Joel can you tell me about idle current..... and how many mosfet's are on one side... And does mosfet's have some thermal compound on it or are dry mounted on heatsink...

what happened to the other one?

did you ever get this up and running

I have thought about these, what is the voltage range? It would be nice if it would go down to 18v or so, so 6s liion would be more comparable, I have a inverter charger, but not likely going to use the charger, being off grid, I have a 7s liion bank, 29.4 v peak. I'm looking for a larger inverter, 200w idle is a bit rough!!

How much is it?

probably doubles as a good room heater too

good

Hey I have a question I need to power my electric carpet cleaning machine. It requires two outlets 17 ams 115 volts and 19 ams 115 and 2 mytee 2400 watt heater i need about 9000 running WATTs total. Can I connect the INVERTER to a small generator because this system requires a 220 pound generator i will have to carry around

What price for this inverter ? How much battery's must connect with it? Where I can buy it?

Wawo 👏👏👏👏👏😯👏👏👏👏

Missing space is for Optional MPPT Charger

The empty space could be for a 100a MPPt charge controller.

So ... 1) This looks a little "beefier" than the Sungoldpower 15k 48V in terms of wire gauge and components. Agree? 2) From previous, it looks like you are using (or are going to use) four 74p/6s Tesla 444cell modules for storage. Yes/No? 3) This looks EXTREMELY similar to what I plan in the future, so I would like to follow your progression if you do intend to (a) hook this up to an MPPT solar controller (b) go off grid and/or generator backup (c) keep posting your trials and tribulations especially with BMS issues, shielding issues, and your determination of upper limits of the unit. Thanks WJ

i have the 12kW version, but my electronics clocks delay 2 min every day, my led bulbs blink lightly when is a load more than 1kW, did you already has this inverter working

You should do an update video. What part of Canada are you in ? I'm hoping west lol. Also do you have link on where you bought the inverter from or directly from them

So where is the the updated video of it running.

So you are a Jack Rickard fan. I stopped watching most of his stuff a few years ago. So he had some influence on the lithium algorithm for these inverters? I too have one of these. Mine is yet to be unpacked. Was shipped mid summer this past year. Still working on my bank of batteries. Im going to be using Nissan Leaf Modules. I have 90 usable ones at this time. I'll be making them into 48 volt packs and want to charge the batteries from the inverter itself. Then go into generator mode when power goes out or to manually switch off grid at night then back on in the morning.

Against the National Electric Code to use anything with out UL approved devices on grid or CSA in Canada. So check the codes for USA and Canada as there is a big fine for not having UL approved or C S A in Canada . Beware .

How did this work out.?

มันมีมาตราฐาน.ISO.V!?คือการผลิตประเภทต่างต่างที่ใช้งานและปลอดภัยด้วย..และปัองกันอัคคีภัยหรือไม่..อู๊ด

No More War

Can you used this without battery?

2x 10AWG wires is almost exactly equivalent to a 7 AWG wire. It's minus 3 gauge, the entire AWG system was based on the idea copper wire is mandrel drawn from a solid copper billet which is 0 Gauge. Each size mandrel was 1 Gauge and the billet was drawn that number of times. This was setup for solid wire, so for stranded wire the cross sectional area of copper is the same but the bundle of strands will increase with strand count so there *should*/has-to-be the same amount of copper in a solid 2 awg wire as a million strand 2 awg wire. This is about 5 minutes of research so learn and get better please!

This is not just an inverter, it is an inverter/charger.

Hi Joel, I am interesting in transformador de 15000 wts, for shipping to Colombia. Thansk for the information.

١٥ كيلو واط هذا كم سعره وهل هو تردد كم المطلوب ٥٠ سيكل فىالثانيه ٢٢٠ فولت سنجل فاز ويتحمل كم امبير

But you can’t get 15 kw only with 48 vdc input if the wattage is low. I believe you must have a high input wattage also .

please update on inverter

There is bigger. I know a company. My 10 kw inverter is great but its not split phase

Empty space is for two 60A mppt charge controller like in my case...

15000 watts how moch prize with super cape site r 12volt. 3000farad

Do you have a link??

Hi Joel, I'm doing the EVTV BMS with Tesla modules and am considering getting one of these like you did, are you still happy with it, any problems over the last few years?

I wont inverter I. 15000watts. What $

15 kw Pirce

I few things I do not like about this model... 1) Only 2 terminal posts to connect the battery to. How the hell will that handle 1000A peak input when the 15KW units handles a brief surge of 40KW? 2) I wish the display would show many things at the same time rather than having to cycle thru them. 3) Why have it only 48V input? Why not something higher such as 60V? I have a 48V DC input UPS that is only 1600 watts output so why would they also use 48V DC input for 15KW surging at way more than that? 60V or even 72V might be better. 72V can be felt if you touch it but is not normally deadly.

Prlce

nope i am using two -24000 inverter

You can not size wire without discussing wire length. Truly you should be looking at every factor that contributes to heat dissipation as well but EEs usually use rules of thumb like a derating for a specific insulation or environment like direct burial vs equipment chassis.

You need to hold the camera still and stop jumping all over the place!

Camera shot is so bad . Shaky shaky

Too much shaky camera.. almost got seizure..
