Guys, due to my situation of living in Ukraine, and having constant grid power supply issues, due to the freaks that attacked my country - I am able to show you a lot of tests in real life. And those are the tests that even the provider/manufacturer of this inverter is never ever showing you.
So here is the thing.
Deye 10kW 3-phase hybrid inverter is AC-coupled through the GEN-port (which works in MicroInv Input mode) with Huawei 3-phase grid-tie inverter of total 22kW power production capability.
Deye itself has 12.5 kW of panels on it, Huawei has 30.3 kW panels on it.
How exactly does it work - it limits the intake from the AC-coupled device using "frequency brakes", upping the frequency to 50.2, 50.3, 50.4 or 50.5 it applies slow braking for the coupled device. and once it reaches the battery full status - it just cliks, and relay turns the MI input off. It will get back on once there is either grid back, or if the battery drains down to 95% in an off-grid mode.
You're an inspiration!!! I have some catching up to do to get to your level, but I am amazed at how much I can generate and consume in a house with 3 old pensioners, me and an EV.
My SoFar HYD-EP inverter acts as an AC coupled as well, it's awesome how it charges from multiple sources of generation.
Love from Scotland and Screw Tooting Poo'tin!!!
thanks, mate!
what kind of EV do you have? are you happy with it? proc? cons? I am starting to look at that option as well I guess.
@@ModernUkrainianHomestead Hi ya, It is the Skoda Enyaq IV80, It Is lovely, Booming Stereo, Big Battery with great range, very big boot for wheel chairs and mobility scooters. Handles good with very little body roll for its weight, it's comfy and super easy to drive.
Our first EV the MG ZS and it was a nightmare in comparison.
This Skoda has converted me, not to save the plant, save the petrol for my Motorcycles lol.
Oh one really bad on hinge is the Lane Assist function.... It panics and snatches at the wheel, it is far too intrusive and the option to turn it off is buried balls deep in the menu screens.
Hope this helps mate.
Slava Ukraini!
Glory to the heroes!
Does your Skoda have any so to say levels of lane assist intrusion?
@@ModernUkrainianHomestead No unfortunately not, it is on or off. On as default Euro Nanny rules 🤬
okay, got you
This is a great video. I just want to confirm that while the Micro Inverter(Grid Tie Inverter) is charging the battery with MI export to Grid Cutoff ticked on, will the Hybrid inverter continously produce power from its own solar panels to provide power to home loads? Assuming that there is plenty of appliance turned on. In the video, there is a small amount of home load being used so I don't have a reference. I appreciate your answer. Cheers!
Deye manages the power form all the sources it has, including those AC-coupled.
It can sell it to the grid, or cannot sell it to the grid.
If the "selling first" is the working more - than it will sell, regardless of the checkbox status.
If the working mode is "zero export to load/CT" - and if the checkbox is ticked - it will not allow selling power from MI input to the grid.
about load - that's summer, so there is the little usage in general (18-20 kWh per 24h). in winter there will be times when 6-9 kW of load is visible (40-80 kWh per 24h for heating only).
I really like the comments and discussions on your channel.
Sorry, I can't add anything meaningful on the topic yet. Good luck!
no worries, everything comes in its certain time
we need affiliate links for the sales.
well, the best to get it is to find it through your local dealer.
or to buy directly on Alibaba.
Paralleled two of them but it was so disturbing when it came to communication
what were the issues you had? I'm curious, since I am thinking to add a second one, to unload my current one a little bit, also I need a bit bigger capacity in general.
Hi, you said this is the only brand who can do this, isn't Victron/Fronius also doing micro-grid (AC coupling, DC coupling and so on)?
check deeper about victron and fronius. their AC-coupling is done on the load side, and here it is done very-very much differently.
Deye/Sunsynk - can run in a completely off-grid mode - and then it will create a microgrid on a dedicated port (not on the load side) for a grid-tie inverter, and will accept all the load from it and manage the power to whenever required. If too much - will limit it using frequency.
Could you provide video to explain the difference between ( 0 export to CT - 0 export to load… ) as I still find this confusing. How it can be set to zero export to CT snd still can check sell to grid . Is thus inverter provide power to home using the same input lines by exporting just enough power for load ?
inverter has got internal CTs. so if you use "zero export to load" setting - it won't feed anything that is before the inverter. cand in general you may put into the load there that is not critical and can go off during power outages.
however, in case you aren't allow to sell power back to the grid, and don't want to put all your load under the UPS-load, you have to use the external CTs, that's what for the "zero export to CT" is meant.
in my case - all the load is a critical one, and I don't use any external CTs
Good day @MordernUkrainianHomestead
Can one also connect a micro inverter onto the load side of the deye or only on the GEN port?
Because the micro inverter is mounted far away in a different building and won’t be possible to have it connected onto the GEN port?
ideally it has to be connected to the GEN-port.
however, it can also go onto the load side, I've actually even done this this way, but in my case the input was barely low - 100-150 watts only, and the load was fully compensating it. I don't know how the hybrid inverter will work, in case if for example you will supply say 2 kW only the load, and the load at that moment will be say, 200 watts only... I don't know if in that case the frequency limiting will work, or if Deye will burn some of its relays due to the opposite current supplied
How are the nuclear power stations doing in Ukraine? Heard that they are preparing them for winter maximum output
yes, current outages are exactly because of the preparations and technical maintenance campaign on the atomic power stations. Next week will be much better, since tomorrow they put 1 nuclear block back to work.
but in a week they will stop another one for maintenance, and so on, after all of them receive proper yearly maintenance.
but people had finally woken up, everybody who can - installs a hybrid inverter + batteries, and those who have a place to mount solar panels - do this.
it is a nightmare, since actually all the inverters and batteries are already sold out, so are the panels, and even more - the supplies that are on the way - are also sold until October supplies...
I guess, it will also help a lot in general, despite solar does not produce a lot in winter.
What a well done Video! I have one question though. Can the deye sell the 10kw of it‘s own solar plus the 22kw going into the GEN Port to the grid when connected?
thanks!
no, it will not be able to sell it all, unfortunately. that parameter is not listed in any specifications, but 10kW Deye has got selling power limited to 15 kW for some reason. thus, it can transit the current from AC-coupled devices up to its' nominal listed continuous AC passthrough parameter, e.g. 45A on each phase, that's in case if you have got enough load to eat it all for sure.
@@ModernUkrainianHomestead thanks for the answer. So you can use all the power while off grid but if you want to sell you have to connect the 22kw to grid. Do you have a switch that connects to Either GEN or Grid?
@@michaelbohm96 yes, there is the transfer switch that works in 1-0-2 mode for Huawei grid tie inverter
@@ModernUkrainianHomestead thank you very much! And all the very best given the situation!
Hi great video, quick question i got 12kw Deye which I have already max out. Can I add a AC couple 6kw to the Deye inverter? What the maximum can I add As a AC Couple.??
theoretically the limit there is the bypass current value. but the only thing you have to think about is that Deye has to have where to pass that energy - e.g. if you are selling it, or if you have load - than it's ok.
un your case - up to 12 kw you can connect easily, if three phase.
if single phase - 6 phase without issues. if more than 6 is required - better distribute is across the phases
👍🏾
Hi, are you off the grid? I was told micro inverter's cannot work without the grid?
I'm on-grid normally. and my microinverters for wind and battery (as well as the big 20kW 3-phase grid-tie string solar inverter) work perfectly in both cases - if there is grid, and if there isn't grid.
once Off-grid - I use Deye's AC-coupling mode, when the grid-tie inverters are supplied to the GEN-port which works in the MicroInv input mode. In this case Deye created them a local microgrid, where they keep operating even if I am completely off-drid
Hi, have you connected the "micro" inverter on gen port?, if i use a deye 6kW single phase inverter, i use a micro inverter with no grid i can sum the power of inverter, so 6kW and micro inverter like 2kW, the only limit is the AC passthrough that is 35A or 40A, so 8kW or 9,2kW, i have seen this sum function between grid and inverter but never between inverter and micro inverter, do you know anything about it?
yes, I mainly (like 98-99% of time) run my 10kW 3-phase Deye with either two or one single-phase small grid-tie inverters, you can call them microinverters as well. it works just as same, but the incoming power is way less of course.
I am using the big Huawei 20kW guy to support Deye, only when there is no grid and if I need a serious power added, so a rare case to be honest.
@@ModernUkrainianHomestead thanks, so in your configuration the deye 10kW 3 phase have can sum the micro inverter huawei 20kW to 10kW = 30kW that is the limit of passthrough current of your inverter that is 45A.
Ultimately, is it possible to use all the current both from the grid but also with the gen port and micro inverter?
theoretically yes, I haven't tried it yet though, since if there is grid I just use Huawei in its normal working mode.
Вітаю. Думаю не тільки мене цікавить питання, чи можна приєднувати однофазні навантаження чи генератори до GEN порта? В інтсрукції не найшов такої інформації.
з однофазним мікроінвертором чи мережевим інвертором - трифазник Deye працюватиме. з однофазним генератором - не буде кіна.
@@ModernUkrainianHomestead Дякую за відповідь. А однофазні навантаження будуть працювати в режимі SmartLoad?
@@ВадимКоролюк-р9я так, будуть
Can you input single phase to Deye 3phase GEN Port?
yes, you can. my wind turbine grid tie inverter is a single-phase as is sent to the AC-coupling as well. moreover, you can combine them as many as you want, and combine three-phase with single phase. all you have to worry about is that the total capacity of those AC-coupled devices does not exceed Deye's transit current requirement (in my case 45A for each phase).
@@ModernUkrainianHomestead Great please kindly help me. How to Install single phase to GEN port 3 phase?
- I have single phase L N G
- I connect L to L1. N to N. G to G. But inverter show only gen voltage no gen power to charge battery or no power to Load.
@@multidev2 are you connecting generator? or microinverter / grid tie inverter?
if generator - it will not work, not possible, generator has to be 3-phase.
however, there is a solution - go buy a simple cheap inverter/charger (like this one for example, 48v one: s.click.aliexpress.com/e/_DlT0MzR) and connect the generator to its AC input and this inverter/charger battery terminals to the same battery the Deye uses.
then you can manually run the single phase generator to charge the batteries, when you see that there is lack of grid and sun and if the battery is getting drained.
if you are trying to connect a single phase GridTie Inverter (wind, solar, does not matter, just has to be the grid-tie one) - just do as you said - connect L to L1 (or L2, or L3, whatever), N to N and G to G and it will work.
@@ModernUkrainianHomestead I have hoymile micro inverter single phase to connect main consumer (home A load). I connect line L N G from home A to Deye 3 phase Home B. It is not work. I am thinking to direct connect LNG from micro inverter not form main consumer. Please help.
no, you don't have to connect the microinv on the Deye load side (at least it's better not to do so without a limiter).
connect the microinverter to the Deye's GEN-port terminals. and set up the GEN-port to be working in MicroInv Input mode, do not forget also to set properly the on/off values. there are many video-instructions on Deye official youtube channel
How big is your house? 100KWh a day is a lot. You should probably check for leaks and isolate your house better.
No leaks possible, as there are no water transfer lines. I use ceramic heaters which are low-consumption (6kW max instant consumption for the whole house).
The house itself is quite big, 300 sqm, also, the 100kWh is only for the days when it's -15-17 Celsius outside.
If it's around 0 Celsicus - the consumption for heating only is roughly 55-60 kWh.
Monthly heating usage was 2300 kWh so far max (in January 2024).
And well, truth is that I have not finished the insulation yet, two small things are still left to be done - the bottom part of the concrete foundation is not insulated at all at the moment, I am starting on it this month though. And also on the underroof floor there are several places where I have to apply additional 200mm mineral wool insulation, that's also the next step to help with reducing the heat loss.
@@ModernUkrainianHomestead I was thinking about air leaks
ah, yes, well, the ventilation is the main one... Everything else is pretty nicely sealed. If you will calculate the losses, they are great actually, given my walls and windows surfaces.
100kW per day, means 4200 kW of electric energy consumed, means, there are 4000 watts of thermal energy losses each hour (on average). And now the surface area of the windows and walls combined is 295 sqm, which results in 13.5 watts of thermal energy losses per sqm (walls and windows), and well, since the floors sqm of the house are about the same as well, it is realistically 5 times less than what is considered to be normal (80 watts of heating power for 1 sqm of room area for example).
If I do your calculation on my house that are in the Nordics then I have a heat loss of 4W sqm, so there are definitely room for improvement in your house.
let me guess - you have a heat pump?
and liquid based heater-tank system then transferring heat to the radiators or to the heated floor system?
correct?
а коли є мережа і батарея повна воно працює на продаж? яка максимальна потужність ac coupling відносно інвертора?
@@ihor.k на ген порт можна подавати не більше струму байпасу. Але за однієї умови - щоб Deye мав куди подіти ту всю потужність. Бо якщо не буде куди - то власне починає працювати обмеження частотою. Але тут є нюанс. Якщо навантаження буде стрибуче - то обмеження частотою може не встигати відпрацьовувати і інвертор буде іти в помилку по overcurrent.
Коли є мережа - можна продавати а можна не продавати, залежно від налаштувань (залежно який режим роботи обрано і стоїть чи ні галка на заборону продажу з Ген-порта).
@@ModernUkrainianHomestead питання в тому що він робить, якщо мережа є і батарея повна, він просто вирубає цей вхід чи пробує експортувати?
є два режими роботи:
1. якщо solar sell і підключено щось на ген-порт - то до сраки в якому положенні галочка Mi export to grid cutoff - продаватиме все і навіть більше ніж дозволено.
2. якщо zero export lo load або zero export to CT і увімкнена чи вимкнена (все одно як) solar sell - от тоді якщо увімкнена галка в налаштуваннях мікроінвертора "не продавати" - тоді при досягненні заданого заряду в батареях - тоді реле вимкне мікроінвертор просто і все. і не увімкне його назад поки не буде досягнуто величини заряду при якій його вмикати.
@@ModernUkrainianHomestead а якщо на цей порт підключити вихід мережевого напр.30кВт інвертора? мережевий стартане ж і видасть те, що буде готовий взяти деє?
I think you need more batteries
indeed.
+1 more is saving my friend right now, he is using it before his battery pack arrives.
but eventually, the problem is that I need about 100 kWh of battery capacity, and I have only a quarter of that... to add up with Deye original is hell lot of money, to replace with Mason/Seplos is three times more cost effective, but still a lot of money... So, maybe I'll just use the DeiselGen to supply the extra once there will be no power.
This is how my inverter works th-cam.com/video/uniz-mTrS6w/w-d-xo.htmlsi=npiWmOprarKXNDG_ It see the power made by other inverter and charge the battery from that inverter and also from the two strings of solar panels attached directly to it. It can charge the battery at 5KW and can act as both on grid and off grid mode.
