I'm ordering a pair of 5kw Hybrid inverters from DEYE - price is good & they're making some units.
These have CEC approval - https://www.cleanenergycouncil.org.au/industry/products/inverters/approved-inverters

They're rated for 5kw, but also do 5kw on battery (most other hybrids are de-rated to 3kw)
Did anyone else want in on this to possibly save on shipping etc. Might also be easier/faster while they're doing a batch run.

I'm based in Sydney...
 
Hi Nate...I just received my Deye 5kw last week, I'm in Adelaide. Because I couldn't buy a single unit directly from Deye I went with an Alibaba supplier. The first supplier said they had stock then after I paid they said it would be a few weeks+ for stock to come in...they did apologies and offered to reimburse me if didn't want to wait 3+ weeks. So after finding another Supplier and having my refund processed by Alibaba (took about a week) I went with the second supplier. I explained what had happened and asked if they could confirm they had access to the unit. After they confirmed with Deye they could get the unit I asked if I could pay half upfront until they showed proof they had the unit in possession....which they were happy to do. They sent me 3 photos of the unit unboxed so I paid the balance and they shipped the unit by air (with CT device) and I received it less than 3 weeks later (via FedEx)....and very relieved as this was one of my first three purchases on Alibaba. I've yet to test/install the unit but it does look and feel like what I've seen on a few different youtube channels for Deye,Sunsynk, SolArk. The supplier I went with and happy to recommend is Sunlink (xiamen) New Energy Technology Co., Ltd, person I was messaging was Liu Jun. Unit was USD$1100, + USD$246 shipping, + AUD$278 paid through FedEx for GST I think. Cheers
 
I managed to get 2 from Deye directly, you only paid just slightly more than me. It appears Deye are not setup to do small numbers, compared to other things communication was very infrequent - fair enough though. I got told the same story - 3 week delay, but then managed to get 2 landed in <2 weeks.
I've done some testing & its a bit tricky/fiddly - will see if there's a chance of getting the JK BMS talking to the units.

I'm also talking with a local guy on bringing them in - he deals with Deye on other products.
 
I bought the Seplos BMS directly from the Selpos company in China through Alibaba...again no issues. I'm waiting on my 16 230Ah cells which have just cleared customs in Sydney I think. Fingers crossed I can get the BMS to work with the Deye. From what I've read on here it should. I'll post in a few weeks and let you how I go. I'd be interested in how your set up works out. I'm very much learning as I go so if you can offer any insights in setting up the Deye it would be great to hear. Cheers
 
Hey guys what specific Deye inverters did you get? Also do they have zero-export limit functionality with a CT sensor clamp?

I went with 2 of the SUN-5K-SG03LP1-EU, the other strong option was to go with the smaller SUN-3.6K-SG03LP1-EU.
The 5k wasnt too much more & would have capacity to use more appliances and feed in more to cancel out my peak usage. It does require a lot more cable though! Everything is 35A instead of 20A (from memory).
I believe the 3 phase units are currently going through Aus approvals.

They are built incredibly well - definitely NOT cheap crap, physical construction is first rate, which says a lot about the quality of the overall product.
Yes they have zero export mode & a few other modes as well - the features are really quite good.
Manuals are here: https://www.deyeinverter.com/download/product-manual/hybrid-inverter-2/

They also have a 3-6k-SG04LP1 which is a 3.6k 24v battery model - not approved in Aus though.

If you are going to get one - reach out, there's a local guy that uses Deye to manufacture stuff & gets containers somewhat frequently, I would've saved a few hundred using him instead of going direct from Deye.

Thanks for the detailed answer! Yep I'm looking for an inverter that's Australia approved and will do net zero export with a CT sensor. 48v battery system, single phase property power.
Roughly how much did you get yours for?
Definitely interested in that fella's contact details. What area he work in?

Cheers

Pretty sure it was right on $2k landed.

I'll PM you his details, he designs Solar powered heat pumps & works with Deye to manufacture them.

What model / price are you looking at?

I am looking at installing solar panels within next couple of months. i was looking at goodwe SK5k-30, 3KW system. I will be interested in this one as i couldn't find any 5KW hybrid AU approved inverters at good price point.

I purchased 2 of the 5kw units & it was around the $1800-2k each mark. The 3.6kw units were a hundred or so cheaper from Deye direct - but i'll ping you the details of the AU person that can import them - it will be cheaper than what i paid direct from Deye as he imports other stuff from them.

Yes mine came with the CT clamp and believe it should do the net zero export....others might be more informed on this

Correct - it can do that.

There's 3 modes:
Selling first: Power loads & charge battery, then anything else exports to the Grid (configurable max feed in power). Load power priority is Solar, grid, battery.
Zero export to load: only power backup load, dont power house or feed into the grid (uses built in CT on grid connection)
Zero export to CT: power backup load & house, charge battery, then dont do anything with excess.

You can also configure zero export power - 20-100W, so make sure you're covering everything....
You can also configure behaviour by time of day! i.e. at 10am, if battery <60% then charge from grid...
there's a lot of options!

Hi Ives. How did it go with the Deye-Seplos marriage? I'm eyeing the BMS for my Deye 5kW too. Are you able to show cell-level data on the Deye?

Hello Nate, how did it go with the Deye + JK?
 
Hey - everything has been running well for a couple months now.

My inverters dont talk to my BMS, and there is ABSOLUTELY NO NEED TO. I use a raspberry Pi to get info from the BMS & put it into Home Assistant dashboard to check all the details.

My Deye units are configured with max charge/discharge rates - 70A each, so max possibly would be 140A. I've only got 4kw panels max on one - so thats 74A anyway. Each unit pulls max 5kw - 100A max anyway, for a 280Ah pack thats fine.
The inverters allow custom voltage settings for charging (it assumes SLA battery when doing this?) - which I set to 55.2 for Absorb & Equalization - which actually gives 54.7v at the battery (just an odd 0.5v diff for some reason). So it hits 3.418v per cell on charge. Float is then at 54.8 - 54.3v at the battery which is 3.39v/cell. This works beautifully & the charge curve is nice & all behaves well.

I'm super, SUPER happy with the DEYE units - the support/company is a bit meh to deal with, but the product itself is flawless.

The only thing i've had to do is add fans to the external heatsink - 2x92mm ultra silent PC fans are perfect. It was getting pretty warm until full charge on a hot day - I prefer to keep temps to a minimal for longevity.

Still in the process of setting up....of the 16 cells i bought one of the 4 boxes came a month later...not the suppliers fault....all on the Australian end.
I've being following a you tube channel - Ray Builds Cool Stuff - which I have found to be a great source particularly as he is using the Seplos 200A BMS...well worth a look

Yeah mine isn't set up yet but I was also thinking where I intend to have the DEYE set up I will add some ventilation fans to draw out the heat

ray does have cool videos, he's on the forum here too @RayfromTX
