Good day

what is the best between the dyness and the pylon Battery's

warranty wise as well

customer service and just overall

Here is something about batteties that were posted by Corne some time back to give you some idea, but I did not see dyness in these tests. The pylons were performing very well.

Batteties😬😂

Hi small side note here, but few of the dyness guys that were with pylontech left the company and made their own brand and labeled it Dyness. Same batteries few tweaks here and there but difference in batteries is as follows 

1: pylons can mix and match 2.4 and 3.5 modules 

2: dyness cannot mix and match so ur forced to stick to battery stack eg 2.4 to 2.4 or 3.6 to 3.6 and so on 

3: the dyness is 3.6 vs the pylon 3.5

4: price! price! price! Dyness are a fraction of the pylons with 10year warranty on the dyness

Just my 5 bob worth ✌

that is what i was looking at i doubt i will want to mix a 3.6 with a 2.4 but do anyone knows in a warranty situation what will perform the best the pylcom company or dyness?

I think they even use the same BMS/balancer setup, but different firmware of course. Of course I don't know for sure, just something I picked up somewhere.

A US2000 is around 18k ZAR or 1k Euro now. I have not seen Dyness pricing, but how much of a fraction are we talking... 0.8 or less? 🙂

I have seen Dyness 2.4kwh @ around R14500.

Like I said in an earlier post

Price! PRICE! PRICE!

Compared to the pylon 2.4s I have seen hovering around the 19k-21k mark

10year warranty on the dyness

I have no horse in the dyness vs pylontech race but I often channel my inner Isabel Jones and although I have not found the South African dyness warranty doc something in the Aussie version caught my eye.... this may or may not apply in other countries..

No comms cable = 5 year warranty not 10

Self discharge rate as defect is only covered for 180 days from install (?)

If you charged and discharged to the tune of 6.7MWh the warranty ends no matter how many years of the 10 are left. Pylontech seems to go purely on percentage of nominal capacity being stored by year 7 or 10

The list of warranty exclusions for both pylontech and dyness in any case appear to have the odds stacked somewhat in favour of the house. Do not know if they will use it but they have plenty "get out of jail" cards to play.

Very interesting read @introverter

Another reason to get the better Hybrid inverter with the CAN-bus connection then. Also, a good cloud logging setup helps, you can prove for a warranty claim that it was not abused or deeply discharged on a frequent basis.

So that's like a car warranty then. 5 years or 100 000km 🙂

If you discharge it to just over 80% every day (2kWh out of 2.4kWh to make the math easy), that's 3350 days, which is just a tad over 9 years. So this does not seem like an unreasonable stipulation. If it was like half that, that would give you pause.

to my mind having the battery capacity warranty stipulated in terms of total throughput is actually the more sensible (realistic?) approach... but a 10 year warranty is easier to digest for the average consumer.

I'm not sure but is the Dyness not a Lithium Ion, and for that reason cheaper.  The Pylons are Lithium Iron (LiFeO4).  See the difference between the Lithium Ion and the Lithium Iron battery technology here: https://ampedoutdoors.com/blogs/battery-blog/lifepo4-vs-lithium-ion

Rumour has it that a bunch of guys that worked for Pylontech left and started their own thing, which became Dyness. The batteries are very similar. Same chemistry. Same CAN-bus protocol. I think it even uses the same BMS design (same chips, @Youda has an excellent write-up elsewhere about the chips used in it). The firmware is different though (of course, that kinda copying is a bridge too far in legal terms 😉 ).

Both dyness and pylontech are LiFePO4, which still get generally lumped into the broad category of being "lithium batteries". (almost nissan x-trail and renault koleos without any CEO hiding in a suitcase...)🙂

Hahaha! That is an interesting analogy. Yeah, I am sad about the demise of Nissan and essentially becoming Renault's step child. A lot of the cool stuff is simply gone now.

First CVT in the Murano? Yeah, it was kinda crap, but it pushed the envelope.

Nissan Micra? What a cute little car, but the successor is essentially the same car as the Renault Modus (platform B).

The Terano is gone, but you can get a Duster. Just not the Diesel one... the last thing you want is a Renault Diesel engine.

Rental companies do like the Sandero though. At least it is less boring than the Almera. My goodness, the Almera was probably the first sign that Nissan had just given up... that thing was more bland and had less power than even the blandest Corolla...

Sorry, I checked myself and to what I can gather the Dyness is defilingly also Lithium Iron (LiFePO4).

I find this a tricky one.

What I like about pylontech is that they are clearly a solid product, they're generally known to be good with quite widespread usage, with independent tests in which they do very well and outperform a lot (most) of the other lithium batteries tested. I'm very happy with the one I have now and strongly considering to just expand with them, they're a solid product.
I feel like I can buy a system that will use them right now, punch the numbers into my ROI formula to see what ROI will be like over 10 years and expect them to actually last 10 years, and that if they don't there's a reasonable chance (assuming I install them decently) that they will be replace under warranty and/or that the company will still even exist to do so.

A 20% discount on the other hand is nothing to sniff at and if I could get the same thing for 20% less its definitely at the very least tempting.

Dyness on the other feel like a harder to quantify risk.
Yes there are the rumours that the people running it were previously at Pylontech, but even if that were true what exactly does that mean? Are they the people who made pylontech a success or did they leave because they were problematic or pushing Pylontech to be lower quality for cheaper parts and higher profit? How would I know? How much is this connection really worth in reality?
The BMS is apparently the same, maybe that's true.
What about the cells though? Are the cells the same quality or are they maybe sourcing lower quality cells?
Do they even have the same quantity of cells? I see the Dyness 2.4 apparently weighs 22kg while the pylon 2.4 apparently weighs 24kg - could the difference in weight be that the pylon 2.4 actually has more cells and reserves some extra capacity to help them last longer (never reaches as low a state of charge) which in effect means the Dyness won't last as long?
Which then brings me to question, if Dyness batteries start dying 6 or 7 years in will they be around to honour the warranty, or are they going to vanish.
Do Pylontech maybe cost more because they reserve some money for warranty replacements, while Dyness are just yet another battery company (in a long line of battery companies) that are going to vanish from the face of the earth before anyone needs to claim?

So in short, is Dyness cheaper because they have a more efficient manufacturing process and thinner margins, or are they cheaper because they are selling you less and/or have a less sustainable?
I wish I knew that answer to that, I have no idea only questions.
And so it becomes a matter of, take the "safer" but more expensive batteries and have a longer ROI, but be more likely to actually ROI for sure.
Or take the cheaper batteries and have the possibility of a faster ROI, but run the risk of having no ROI at all if the batteries go poof a few years in...

Still thinking about it myself, but I tend to be conservative on these things, for now I favour pylontech, I really like that theres detailed independent testing data as that is something I can really trust to some degree, though I hope someone comes up with more detailed and certain information on the dyness.

Hello @Cassie Lithium Ion is a the category name given to a number of Lithium based batteries with difference active materials. Namely: Lithium Iron Phosphate(LiFePO₄) — LFP being most popular for its advantages but there are many more... While not an expert, I have done a lot of reading as i look to switch my system from AGM to a Lithium-Ion alternative. This is the best resource that i have found with a great comparative explanation between different types: https://batteryuniversity.com/learn/article/types_of_lithium_ion. I'm not sure how 'apmedoutdoors' got to their sales pitch on their website when i have seen a few of these Lithium-Ion derivatives on the market.

I can give my experience with Dyness. I have two powerbox 9,6KW. Whatever small tweaks were required to get them working with my previous Growatts, (previous, because they are really not great inverters), Andy from Aspergo (one of the distributors), is next level when it comes to assistance. He flew down twice to Cape Town to assist with my batteries, uploaded firmware, swapped cables if required, swapped out to the latest BMS cards (I purchased the two powerbox's at different times, so the one had older cards in). Andy really is next level when it comes to service and wanting the best for the brand. What makes it even more impressive is that originally the batteries didn't even come via his company, so where other distributors gave me the run around, Andy sorted me out. 

The two units are working perfectly in parallel, the BMS works well, they look good, and they are doing a fantastic job, connected to a SunSynk inverter. 

I wouldn't hesitate buying Dyness again, when spending this sort of cash on batteries, you want to know that you have support and someone who actually has your best interests at heart. 

If you are going to buy, I highly recommend contacting Andy to ensure you use the channels that connect you with him. 

Cheers all

What is the contact for Andy.

I am thinking of inst5a5lling the Dyness 4.8 kWh 48W with Growatt 5k inverter. Can this combination work?

Hi @Siya congrats on your purchase. Yes that combination should work but you didn't specify the model for your inverter.

If you have a growatt spf5000es you should use the CAN port and use protocol 52.

If you have a growatt spf5000tl then you will have to use the RS485 port since it doesn't have a can port.

 

My 2Rand. I've been running Dyness B3s with Growatt SPF5000TL-HVM-WPV-P (3 parallel) since Aug 2020. First 4, then 8 and just added 2 more for 10 total. Dyness and Growatt support has been great although my direct email contacts appear to have moved on. Early on required some effort to get firmware up to date on all the components and accurate installation instructions required some effort to get things all working together. That said, happy with everything.

I have two batteries that are exhibiting faulty BMS at the moment so I get to deal with Dyness support again.

I'll report back for 2023 since I need to deal directly with Dyness since the local distributor I used for my original batteries is out of business.
