Yellow Measure

Good day Gents,
It has been a minute since an update: The idea in this instance was merely to get the inverter up and running. However there are a few minor complicating factors that can make this impractical. Components availability is the primary area of concern, because a number of the components employed, are not off the shelf. Having exhausted a number of avenues as well as myself in the process. I initiated contact with Luxpower. I waited and waited until I eventually received a response.
We have maintained a near daily contact, which ultimately resulted in the reception of two “DC Board Assemblies” and one LCD screen assembly. Circumstances are 1 on 1. However, I am of a strong belief that they will reasonably assist in any way possible, so long as the request(s) are reasonable.

Brand new board assys /w drivers: Both are several months apart. From mid 2025 to late 2025. How do I know? The date code is on the xfrs. There are at least 3 separate revisions. Based on part numbers

Brand new LCD assy

Board being replaced (missing the two GDT) “isolation transformers) those had a date code of 2316 or the 23rd year and 16th month. (The cable retainer was removed from the original board and installed on the second new board) It broke in transit and took but a minute to remove and reinstall.
This will be a very difficult week, and I am not 100%. In addition, I have not yet received the thermal grease priorly ordered, per manufacturer’s specifications. Next week I will provide a final update on a complete and fully functional hybrid Inverter, one that I have really grown to love and the little bits that sets it apart from other inverters, that I have not had the greatest of success with; longevity speaking. I can say this much: unlike most companies, Luxpower has owned up to its mistakes and has made a pledge to prevent future failures such as this. As a sceptic; I genuinely believe that they will. Having once worked in PCB manufacturing and later, IPC Compliance ISO 9001:2015 there are significant differences between the mainboards. Same parts different quality controls.
***Note*** I am not in any way affiliated with Luxpower or its subsidiaries; otherwise my inverter would have been repaired several months ago.

Update:
545wp Longi PERC panels replaced by 665wp Akio bifacials. From 2180wp to 2660wp+bifacial on the same footprint.

Okay, so then the R2K on offer (approx $120 USD) is about middle of the road or average for the reported international scrap value of the battery. Just stating the obvious.
I'm sure the newer batteries are better and more desirable, but each one must maar decide for himself how much his old generation battery is still worth to him.

Thinking/speculating a bit more about the on-board power supply, there is probably a single power supply connected to the DC bus that powers all the electronics - so there is probably some fat in the 12V supply.
This is a good suggestion, will check to see how easy it is to make a connection inside the enclosure.
Thank you for your input!

Wow. You must be a hoot at parties.

Hello All so just an update more than 6 Months later my turbine is still working fine needs to be serviced however will get to it sooner or later
Great wind the past couple days this is only pure wind power production the data interval on the inverter makes the production look erratic however its pretty constant even though the wind is quite gusty. Also got the turbine logger working will share some data from that at a later stage.

As you can see on this graph the wind power kept the battery almost at the same SOC throughout the night only dipping off a little at 5:45AM had to run some heavy loads last night to get the SOC to go down so ran the aircon in heating mode had the geyser running etc.

Wind is still pumping however not enough load and the battery is 100% full so the turbine is currently just dumping power to its dumpload.

Kynee is a huge company in China, they even white-label their batteries to other manufacturers. I recently purchased the Hina ESS PowerGem Max, at the time I new nothing about Kynee and I assumed that they were new entrants with no track record, that's what steered me towards the Hina. Imagine my surprise last week when I discovered that the Hina ESS is basically a white-labelled Kynee!
The Hina ESS (Kynee) has excellent build quality, packaged very well, and the documentation that comes with it is glossy and superb. The Hina app is not as good as the Kynee one though, there is far more information and settings available on the Kynee app, so the Hina app in comparison looks a bit "dumbed down". I guess that it's OK if you don't want to be in control of everything.
Had I known what I know now, my purchase decision would have been different, and I would have benefitted from saving a few thousands of rands buying the Kynee.

Since you are not technical then in order to determine if the earth leakage is on the AC supply to the inverter or AC output of the inverter switch the earth leakage off and if the inverter goes to battery mode then you know that the earth leakage is on the supply side and if the inverter does not go to battery mode then the earth leakage is on the AC output of the inverter.
The alternative is to ask the installer or an electrician to come and inspect the installation to determine if the earth leakage is on the AC supply to the inverter or AC output of the inverter and draw a diagram of the system.

Can be anything really. Diagnosis of such a fault is almost impossible unless there is some tester I’m not aware of that can find it for you.
I can be the light circuit, pool circuit, the DC side on the panels, it can be anything. Sometimes you just have to wait until it becomes really bad then you can easily identify which circuit is the problem.
Until then you will be hunting for an intermittent ghost. If you are lucky the fault will stay on long enough so that when you attempt a reset of the EL it trips again then you need to quickly check which DB circuit it is.

I think that you are onto something, and I like your approach, but words matter. Raw material value would be the input materials at the Pylontech factory, before they assemble it, test and put it on the market as a brand spanking new battery.
Salvage value would be the value of the battery after someone has used abused it by applying "a few high voltage charges", and it swells up like a marshmallow in a microwave.
I asked Grok, who gave a detailed, interesting response:
So it turns out that chemistry, condition, location and volume are relevant (no extra dollars for the marshmallow ones!). Hubble AM2s are NMC, Pylontechs are normal LFP. And remember: this is in the US, where they have recycling industries that can leach the chemicals and re-use them, not South Africa. So I asked Grok again, this time specifically Pylontech US3000s, and the response was that in SA, one would basically have to pay the recycler to take it away 😄

Eish met Coke yup !!!

I think we need to stop here, before the Mods nail us for making them spill their hot chocolate...

Rotfl PHD !!!! Next Level !!!! I subscribed and got the badge!

The Coulomb Counting is a separate field of study entirely, reserved for the PHD Program at Buttery University 😆

Rotfl 😂 😂 😂 I can't Columns Columns 😭🤣😭 Masters Degree....

LOL. That's reserved for those that have a Masters Degree in Cycle Count. 😆

Bawahaaaa! Crying 😭 😭 😭 😂 😂 😂 😂 eish...

Yet Pylontech offers R2K eish man eish...

Hope you well. Where are you located?

How on earth would the Power Forum a trusted free resource take responsibility for your batteries? Please send me what you are smoking seriously... 😎 The okes at Power Forum has always been solid maybe your Question should be focused on Pylontech....Besides Pylontech knowing the risk is attempting to engage with guys like you 🤣🤣🤣 a fortune 500 company engaging with the 44 left in SA but who am I 😛 I see it as refreshing and positive does Sunsynk do the same ? With 6 month plus warranty repairs? ....nope ..... It's a joke 🤣.... But the BMS should have Functioned at 275000 KM per second...just because you used a crappy budget inverter... seriously send me what you're on...

The batteries were abused, all 3 of them.
