You say you have a 20kWh grid-tie Huawei, a brand that is easy to get in Asia (where I live). I wonder why you switched to Deye; a brand that is available here, but not so easy?
Deye has got the perfect (probably the best) hybrid inverters, unlike Huawei. and Huawei has got probably the best string inverters. That's why I used a combo. Since I need a piece of hybrid to be partially (even fully actually) autonomous, and I did not want to overspend a lot of money while going all hybrid, since the string inverter 20kW is about twice cheaper than 10kW hybrid. AC-coupling - is the scheme that makes them both work together in perfect combo, so I can use the string inverter even during the times when there is no grid, I just supply it to my hybrid inverter and use all the energy I need.
my Deye is 10 kW, 20 kW - is my Grid-tie Huawei. but in general, all Deye hybrid inverters have those same functionalities. question only lies in single or three phase setup.
I love this feature as my house is always turning different loads on different phases. However Deye is not available in my country. Any idea if Sungrow does this?
unfortunately. no idea if Sungrow does this. I know that Deye is also sold under Sunsynk brand. and there are a couple of smaller subbrands, but it in any case has to look absolutely same as Deye does.
Goodwe supports unbalanced phase feeding as well. Maximum power per phase the 1/3 of the nominal power. Deye can provide until 1/2 of nominal power per phase. Also I have heard that Fronius will provide an update and will support unbalanced feeding as well.
@@parisvar @modernuk GoodWe although exists here doesnt quite have the support. I spoke to Sungrow and they say the SH25t which Im interested in does provide unbalanced phase feeding, though not sure if its 1/3rd or 1/2. Their website confirms this too. At times if I have 2 to 3 ACs on one phase (my house has several more), the draw can increase to 7ish kw on a single phase so this part is rather crucial. They are also offering a 10 year replacement warranty so I think Ill try them out. Fronius apparently is the best but it has a drawback, the power switch from grid to battery takes 30 seconds. Its not instantaneous. Sungrow states theirs does it in 10ms, Tesla style. I classify that as a luxury feature almost and a musthave
@@ModernUkrainianHomestead I had seen a video of super deye 5kw hybrid inverter which has the ability to get DC input from wind turbine controller I wanted to know does this specific model also have the feature can I used one MPPT for wind turbine out put & 2nd for solar string ? Also as mentioned 3-phase output can I run 3 phase induction motor ??? Would it keep the phase angle perfect on start up ???
I want to install a wind turbine inverter to the gen port. Your wind inverter has three phases? Or you just connected one phase? Could you show me how you did your installeyion? Thanks
I used the dedicated wind turbine grid-tie inverter - link is in the video description. you cannot just input the wind turbine directly to GEN port, it doesn't work in such way.
Hello and congrats for all the detailed information presented. I have as well a fronius gen24 10kw inverter with 13kw panels and i'm looking into expanding the system with a deye hybrid for microgrid function and LV batteries backup. I would like to ask you as i am planning to buy a 12kw deye hybrid inverter with pytes batteries and connect on gen port the existing fronius and install extra 6kw solar panels directly to deye. Can deye handle all the load and export to the grid in the same time taking into account that will total 16kw but the inverter will be only 12kw? or i will need to go for bigger inverter?
yes it will be able to do what you expect from it. my 10kw Deye has the total selling capacity of 15 kw, so I guess, 12 kw should have either same or slightly bigger selling capabilities value.
@@ModernUkrainianHomestead can you tell me where I can find on the deye inverter spec sheet the maximum allowed power through it? how is deye behaving when you have only one or two grid phases failing? Is it disconnecting by itself totally to microgrid, isolating the main grid? Will the other inverter stop while doing this transition or is switching to batteries without any power loss. Thanks again for your help 🙏
it will definitely switch to its own microgrid if the parameters of the external grid somewhat are not ok, and it will get back to the outer grid once it gets stable (and after the specific delay time had passed, settable from 1 to 100 seconds). specs? go for www.deyeinverter.com/ or deye.com/ they don't hide anything, and from my experience I can tell that the specs are not over exaggerated, they are true to what is stated.
@@ModernUkrainianHomestead i was referring at the spec sheet regarding the maximum power allowed through the inverter. as you mentioned before your 10kw inverter can get 15kw through and wanted to check for 12kw inverter. so if any of the grid phases will drop it will disconnect and change to microgrid on batteries?
@@jordache1981 ah, that value is not mentioned anywhere, true. and 15kw is the max selling power for my 10kW inverter which I managed to figure out only via hitting the max value available in the settings "max solar sell". as of the continuous AC passthrough - that's in the specs, and it's 45A for my 10kW.
that's just the default setting of 55 Hz. it is used mainly to engage/disengage relays of both Grid-supply and GEN-port supply (Microinv Input in AC-coupling mode, or Generator input in Gen-mode), in case the power supply is way too off - it will simply switch it off. Why such high setting? Since if you are for example using any strong 3-phase motors, and even smaller single-phase motors - they have a huge starting current, that modifies the sine heavily, and alters the frequency as well. so it is standardly used at the higher end of tolerance on frequency and on the voltage as well.
if Deye works without batteries - it's as stupid as any other standard grid-tie inverter. to unlock all the potential - add batteries for sure. and to have the batteries work in their optimal mode - they have to be of at least x2 in capacity of the inverters nominal power. about phase assymetry I cannot answer your question unfortunately, as I have never had a chance to check it.
you mean for a 25kw hybrid inverter, I will need x2 of nominal power which is 50% of rated capacity, so 12.5 x 2 = 24kwh battery?@@ModernUkrainianHomestead
@@shaazy yeah. if you have 12 kW rated Deye - it will likely work fine on +10% of that continuously. but for the surges it may withstand about +50-60% short term (like a couple of sec) power. as of the batteries, you need x2 rated value, so 24 kWh would be good. but I mean it will also work if you have only 5kW battery installed there, it's just that you won't be able to use the full inverter's power in case you'd go off-grid. as the battery would become a bottleneck in that case. but from my experience - batteries is something you will never feel you have enough, so definitely about the power bank the true rule is - the bigger the better.

Very useful information. Good job!
thank you!
Thank you very much for the video. Could you write what model of batteries you are using?
I use Deye original ones, these specifically are Deye SE-G5.1 Pro

10 ms is necessary for computers, servers and other sensitive devices, 30 seconds is literally ages...

Does phase asymmetry only work with battery storage or is PV alone sufficient?
if Deye works without batteries - it's as stupid as any other standard grid-tie inverter.
to unlock all the potential - add batteries for sure. and to have the batteries work in their optimal mode - they have to be of at least x2 in capacity of the inverters nominal power.
