Дуже дякую за відео. Наскільки я зрозумів про що мова, то є он грід інвертор, який дає певну потужність у внутрішню мережу, що також створює навантаження на лінію Deye, що видає потужність. Якщо так, то виходить інвертор Deye здатен приймати на себе зворотню потужність від ліфта, що використовує рекуперативне гальмування?
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
Hey nice video, I was wondering if you could tell me if I can use that AC couple feature on a hybrid 10kwh triphase deye that has no battery installed and tied to grid. it would be set to No export to CT. Can it work like that?
Many modern inverters actually allow ac coupling with existing solar inverters for both string and micro inverters Like Luxpower, powdrive (which is actually a Deye inverter under different branding and 1/3rd cheaper)
@ModernUkrainianHomestead you really missed everything I said I know lux is different from deye The inverter that's a complete copy of deye is powdrive n that's what I said Still doesn't negate the fact that most inverters in the market allow retrofitting either by ac or DC coupling
ok, I missed it. I just doubt all those "many inverters on the market" know how to limit the higher power AC-coupled device... The difference usually is in tiny details, if you know hat I mean
@ModernUkrainianHomestead in all honesty that's common knowledge as most of these inverters are actually being manufactured by very few manufacturers You can't go wrong with most
no, not really ) there are quite a number of manufacturers. Would you believe it or not but even that bunch of shit-cheap chinese inverters (EAsun, Anern, PowMr, Must, Daxtromn, ESGSolax and many more) - they use 3-4 different factories to get those produced, and all of them can even be produced at the same factory. But Deye is Deye, it is very different. It is only also sold under SunSynk brand in some places over the world, but they had neve been hiding that it's Deye by metal, just the software is different. powdrive is a tice-try cheap copy of deye, and deye has nothing to do with it. unfortunately.

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
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?
yes, there are the factory cooling fans. my solution could not eliminate it fully, but it reduced the frequency and time of the factory ones are working
I am happy with Deye, definitely. Over-the-air updates means constant improvement even of the old unit. Moreover, very-very soon, like in about 3-4 weeks, another one 10 kW same unit arrives and will be installed in parallel to the existing one, I just need to double the load-bearing capacity for a pure autonomous mode, as well as I am hugely increasing a battery bank (not Deye this time, since they don't produce huge 15 kW battery units). My old Deye battery bank will still be in use, just in the other place, in the garage. So said - I've had zero regrets of getting Deye, and getting more of their inverters. I also think of replacing my grid-tie Huawei to Deye hybrid, that's the next year project probably.
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
Вітаю. Думаю не тільки мене цікавить питання, чи можна приєднувати однофазні навантаження чи генератори до GEN порта? В інтсрукції не найшов такої інформації.
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).
Thanks for the video and the clear explanation of how you have coupled the Deye and Huawei systems -- I should have watched this video before asking my question earlier today, as I watched a video you posted in June but I did not see it until today, 11 Nov. Thank you for answering my question on the June video -- but double thanks for this video which clears up some lingering questions that I had. Finally, I hope those R idiots get the H out of your country so the Ukrainian grid system can be restored to normal -- all in the very near future...
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.
@@ModernUkrainianHomestead It's also working on the load side for the DEYE... Paradoxally I prefer to do my AC coupling on the load to not let warm the DEYE inverter as it can be when AC coupling is done on the GEN port...
@@sebydocky5080 yes, I tried that as well, but with the tiny current supplied (like 100 watts only). not sure if it will work with huge currents and power. how is it in your case if you say supply 10 kW to the load side, on 10kW Deye inverter, if there is actual load of 1 kW for example. Will it also limit using the frequency mechanism if say, batteries are almost full?
@@ModernUkrainianHomestead Well, got in AC coupling only 1.3kWc for my 8K DEYE (most of my solar panels are in DC coupling). No problem with such AC coupling loads... and yes as soon the battery reaches (55V), the DEYE shift to 52Hz to put in default my grid tied inverter (a SOFAR solar). To be more precise, the 52Hz occurs with one of these two conditions : battery > 55V or charge batt from deye + charge given by the grid tied < max charge (A) setting of the DEYE. Since my SOFAR supports zero injection (anti reflux) with a CT, I plan to install the CT on the load side of the DEYE (since I am fully offgrid) in order to enjoy AC coupling even when the battery is fully charged. In orther word with such setup, the DEYE won't shift to 52Hz, instead the SOFAR will modulate his own production according to the CT plugged into the load output of the DEYE
@@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).
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?
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?
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.
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.
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
This is how my inverter works ua-cam.com/video/uniz-mTrS6w/v-deo.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.
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.
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?
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.

@@timosuvhm Yes, I use that option to charge my batteries and supply the load from GEN-port (I use it only as a MicroInv input in my case) almost all the time.
Дуже дякую за відео. Наскільки я зрозумів про що мова, то є он грід інвертор, який дає певну потужність у внутрішню мережу, що також створює навантаження на лінію Deye, що видає потужність. Якщо так, то виходить інвертор Deye здатен приймати на себе зворотню потужність від ліфта, що використовує рекуперативне гальмування?
будь ласка. так, може працювати, якщо цей ліфт матиме мережевого інвертора в якості джерела живлення.
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
Hey nice video, I was wondering if you could tell me if I can use that AC couple feature on a hybrid 10kwh triphase deye that has no battery installed and tied to grid. it would be set to No export to CT. Can it work like that?
I think it should work. however as usual, if there is no grid - everything will shutdown.
Many modern inverters actually allow ac coupling with existing solar inverters for both string and micro inverters
Like Luxpower, powdrive (which is actually a Deye inverter under different branding and 1/3rd cheaper)
no, luxpower is luxpower, and deye is deye...
you can't mix those - and they are waaaay too different ))
@ModernUkrainianHomestead you really missed everything I said
I know lux is different from deye
The inverter that's a complete copy of deye is powdrive n that's what I said
Still doesn't negate the fact that most inverters in the market allow retrofitting either by ac or DC coupling
ok, I missed it.
I just doubt all those "many inverters on the market" know how to limit the higher power AC-coupled device... The difference usually is in tiny details, if you know hat I mean
@ModernUkrainianHomestead in all honesty that's common knowledge as most of these inverters are actually being manufactured by very few manufacturers
You can't go wrong with most
no, not really )
there are quite a number of manufacturers.
Would you believe it or not but even that bunch of shit-cheap chinese inverters (EAsun, Anern, PowMr, Must, Daxtromn, ESGSolax and many more) - they use 3-4 different factories to get those produced, and all of them can even be produced at the same factory.
But Deye is Deye, it is very different. It is only also sold under SunSynk brand in some places over the world, but they had neve been hiding that it's Deye by metal, just the software is different.
powdrive is a tice-try cheap copy of deye, and deye has nothing to do with it. unfortunately.
Вітаю, розкажіть про налаштування мережевого хуавея щоб він керувався частотою, бо маю такий самий сетап але хуавей 30 квт, поки що не вдалося добитися того щоб дея керувала потужністю хуавея. Дякую
@@Igordndz це працюватиме добре лише якщо виконуються дві умови:

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
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.
Is that inverter fan noise in the background? I thought your push/pull fan solution eliminated the noise?
yes, there are the factory cooling fans. my solution could not eliminate it fully, but it reduced the frequency and time of the factory ones are working
Hy. You are still accomplished by your deye? I want to buy one, and I'm not sure if to take deye or victron, but with more money.
I am happy with Deye, definitely. Over-the-air updates means constant improvement even of the old unit.
Moreover, very-very soon, like in about 3-4 weeks, another one 10 kW same unit arrives and will be installed in parallel to the existing one, I just need to double the load-bearing capacity for a pure autonomous mode, as well as I am hugely increasing a battery bank (not Deye this time, since they don't produce huge 15 kW battery units). My old Deye battery bank will still be in use, just in the other place, in the garage.
So said - I've had zero regrets of getting Deye, and getting more of their inverters. I also think of replacing my grid-tie Huawei to Deye hybrid, that's the next year project probably.
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

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
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).
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.
Thanks for the video and the clear explanation of how you have coupled the Deye and Huawei systems -- I should have watched this video before asking my question earlier today, as I watched a video you posted in June but I did not see it until today, 11 Nov. Thank you for answering my question on the June video -- but double thanks for this video which clears up some lingering questions that I had. Finally, I hope those R idiots get the H out of your country so the Ukrainian grid system can be restored to normal -- all in the very near future...
thanks!
and you are welcome
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.
@@ModernUkrainianHomestead It's also working on the load side for the DEYE... Paradoxally I prefer to do my AC coupling on the load to not let warm the DEYE inverter as it can be when AC coupling is done on the GEN port...
@@sebydocky5080 yes, I tried that as well, but with the tiny current supplied (like 100 watts only). not sure if it will work with huge currents and power.
how is it in your case if you say supply 10 kW to the load side, on 10kW Deye inverter, if there is actual load of 1 kW for example. Will it also limit using the frequency mechanism if say, batteries are almost full?
@@ModernUkrainianHomestead Well, got in AC coupling only 1.3kWc for my 8K DEYE (most of my solar panels are in DC coupling). No problem with such AC coupling loads... and yes as soon the battery reaches (55V), the DEYE shift to 52Hz to put in default my grid tied inverter (a SOFAR solar). To be more precise, the 52Hz occurs with one of these two conditions : battery > 55V or charge batt from deye + charge given by the grid tied < max charge (A) setting of the DEYE. Since my SOFAR supports zero injection (anti reflux) with a CT, I plan to install the CT on the load side of the DEYE (since I am fully offgrid) in order to enjoy AC coupling even when the battery is fully charged. In orther word with such setup, the DEYE won't shift to 52Hz, instead the SOFAR will modulate his own production according to the CT plugged into the load output of the DEYE
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?
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?
@@Bboy-1990 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!
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.
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.
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
This is how my inverter works ua-cam.com/video/uniz-mTrS6w/v-deo.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.
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
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?
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.
