Comparing the Deye Inverter to the Growatt Inverter

In the battle between the Deye and Growatt which is the better inverter?

[@adon8672]

Thanks for the wonderful video as usual Dr Solar. I'm positively surprised that these DEYE inverters are sealed and IP65 certified whilst still having fans. They are definitely in a class of their own. Please I'm joining the other commenters in asking for a thorough comparison between the Deye and the Lux inverters. Keep up the good work.

[@billbreaker1680]

I agree... I would want to see also the comparison of LUXPOWER and DEYE inverters...

[@drsolar]

I don't have a LuxPower inverter in my possession so it won't be a fair video. Once I get one I will. As to the fan. I have asked the question too. The heat sink is fairly large but when you decide to charge at 120 amps you will generate a lot of heat.

[@drsolar]

@@billbreaker1680 once I get my hand on one I will. Thank you for watching

[@liveskippers]

Thank you for your comparison. Very helpful. We've also had some issues with the GW's and are in a high humidty and dust environment with various failures. Found this researching the DEYE so will give it a go. Thank you.

[@drsolar]

Glad you found our Channel. In areas of high humidity and dust you need an inverter that can withstand them. Thank you for watching and commenting

[@robortkristensen3818]

Hello Dr. Solar. Thanks to you, I have ordered my own Deye 5 kW hybrid inverter. I hope I can use it to charge a battery with cheep rate grid power, and discharge battery during daytime when grid power is expensive.

[@drsolar]

Congrats on your decision. You will love the inverter . Yes you can do time of use and select the times you want it to charge the batteries. Thank you for watching

[@moineagu1]

Brilliant project congratulations

[@drsolar]

Thank you for watching and commenting.

[@007silverwings]

Do you know what the black button is for on the inside of the Deye above the grid input? Thanks

[@drsolar]

Thank you for watching and commenting. I have not used a Deye inverter in a while

[@marcoa.rosado4724]

Yes, Growatts just not there you can do the side by side with the Luxpower as Moffat mentioned. But Deye is in a league of it's own.

[@tirivaenim]

Marco A. Rosado Noise decibels of Deye vs big heat sink of LuxPower especially when both are placed indoors makes the LuxPower an inviting prospect. The performance, ability to have a more configurable interface with Deye would that make it the only plus or performance of Deye as a Grid-tied/hybrid inverter is what I’m trying to explore as well. I’m convinced Growatt still has some ‘watt’ of a ‘growing’ to do, if you pardon the pun😀

[@drsolar]

I agree on the growing

[@kwakuafriyie2954]

2Growatts spf5000es offgrid inverters failed me in the last 6 months. I had serious error messages esp (08) accompanied by sudden shutdown of system usually around 1am-3am within 3mo of first installation. A newer model(11401) was procured and installed .The error message and shutdown around, 1am-2am, restarted within 2weeks. What could the matter be in your opinion ? I gave up on growatts. Firmware challenges??? Your expert advice please. Deye, worth trying , Doc.? Thanks for your education

[@drsolar]

I am sorry to hear of your problems. We ran from Growatt 4 plus years ago. Too many problems.

[@UK100Adam]

Battery Voltage range. I know Deye claim 40-60V battery voltage range, but I know from experience (8KW version) that the discharge current rolls off below 44V. Do you know if the Growatt is any better in this regard?

[@drsolar]

Thank you for watching and commenting. I have not used a Growatt in years so I can't really tell

[@hadisoewoyo8739]

Hello, can you compare the efficiency of those inverters?

[@drsolar]

We don't support the Growatt, so your request is not likely to come true. Thank you for watching and commenting.

[@jonathanremoblas516]

Is the DEYE have an automatic switch ON function? or I need to switch it ON manually again when the power resume? As I see in the bottom have a power ON/OFF button. Thanks..

[@drsolar]

The power button turns the inverter off and on. If PV or the battery is present it will come on with no need to touch the power button (if in on position)

[@jonathanremoblas516]

@@drsolar thank you for the reply.. keep safe Dr. Solar..

LuxPower vs Deye at 5kva comparison please including ground protection and lightning protection

[@marcoa.rosado4724]

The Deye has built in lightning protection. Not sure about the Luxpower.

[@billbreaker1680]

@@marcoa.rosado4724 wow... very nice feature of Deye to have a built-in lightning protection already. Maybe that's the reason why Deye inverters are more bulky than Luxpower counterparts...

[@drsolar]

I will do one soon

[@utkarsh329]

For ongrid inverter what would you recommend deye or growatt?

[@drsolar]

We only have used the Deye. So I don't have any experience with any other

heelo friend after 3 years did you have problems with deye inverter or no kind of any problems in 3 years ?

[@drsolar]

I personally don't use them anymore. They have been okay for most of our customers

Do you mind sharing further. I ask as I'm looking in to picking u p about 10 units shortly. Do you think I should look else where?@@drsolar

[@jhojaD]

Hello greetings, excellent video, I have a question, this inverter could place a string of 250 and 18A for each PV input, that is, 4s2p or only 5s1p is possible

[@drsolar]

The current rating is low. I will do 8S

[@Skip2MiLuu]

Hi, Have any experience with a Sunsynk vs Deye inverter and if there is much difference

[@drsolar]

They are the same with different firmware. Thank you for watching and commenting

[@Skip2MiLuu]

@@drsolar Is there much of a firmware difference, of is it negligible? So not enough for you to pick one over the other. Thanks in advance if you have any thoughts on the matter

[@drsolar]

@@Skip2MiLuu Thank you for watching and commenting. Sunsynk runs proprietary firmware that has a much simpler and fancier interface. In terms of performance they do the same

[@andrewzetina5412]

Dr. Solar where do you purchase the Deye from

[@drsolar]

Send me an email and I will introduce you to my rep. [e-mail]. If you are in the United States you can't purchase from her

[@kushis4ever]

Hello, I have come across a brand called AUSTA which looks similar to DEYE. Do you know anything of AUSTA?

what is different between sg05 and sg03 or sg04?

[@drsolar]

Thank you for watching and commenting. I am not really sure.

[@Siolioli]

I have deye5k inverter and use lithium battery without bms, yet i see critical issue: charge voltage i'm setting in battery page are not properly used, inverter use bigger actual voltages. I think this is normal for lead acid batteries, but it isn't ok for lithium. So, for lithium to be safe deye REQUIRES smart BMS which can talk to it. If i knew that limitation in advance - i wouldn't spent extra money on deye. (my batteries are non standard 2P 12S 2P, finding proper BMS is pain and expensive)

[@drsolar]

us the lead acid settings. And then use voltage don't use percentage

[@Siolioli]

@@drsolar that's what i use, yet it still charges with voltage above ones i've set. I can limit voltage in "time of day" feature, yet it doesn't work for solar charge, which goes above that, so the only limit should be voltages in Battery config. As of now i've set 48.6V there to have it actually stop charging at 50.3V, yet i can't trust it will just work that way as actual V is bigger than set voltage.

[@charliejjj7594]

Is the Deye inverter noisy???

[@drsolar]

Yes when the fan comes on it can be noisy

[@goata007]

@@drsolar How often and under what condition does fan come on?

[@drsolar]

@@goata007 very nice question. It is driven by the temperatures inside the inverter and if you are charging with the grid. There is no way of telling when. The temperatures inside the inverter decide. It monitors the AC and the DC side

[@goata007]

@@drsolar I'm planning on getting this inverter because my current Infini 10KW has fans running all the time. Since this one has fans coming on as well, probably quite regularly, I'm guessing its noisy as well?

[@iartsofficially]

Thank you for this Video. I am writing you from Brazil and we also have our dust issues here :) Just a question. Would you recommend in general Deye over Growatt independent of the Model? The quality seems massive better when I compare just the visuals from your video. But I am curious if this is allover the company's products similar. Thank you in advance.

[@drsolar]

You are welcome. Without hesitation I will pick the Deye. For PV inverters Growatt is more established

[@iartsofficially]

@@drsolar Wow! Thank you so much for your super fast reply. I am looking at a Deye Sun 8K-G( TRI) Would you consider this a good product and better than a similar 8kw Growatt. Thank you again for your time Dr.Solar, your videos are great and give a lot of useful information. I trust in your judgment!

[@gratiancristea2252]

Deye 12kw hibrid is an asimetric inverter

[@drsolar]

I honestly don't know. I read up on it and the answer is unclear

Different markets.

Does the Deye have a modbus or other documented interface for custom software communication/control
