Since you have a monitoring app, please provide a data chart of your battery's voltage from the same day the inverter shutdown, so that we can check whether the voltage drop has some pattern or not. Additionally, if you can provide charts from several days having this sudden shutdown happening, it would be perfect for debugging! The best and fastest way to diagnose your problem is to test another inverter or another battery in your solar system, if possible.

 

I’ve checked, and all the values are normal (battery, load, etc.), except for one particular day when all the values and measurements were messed up. On that day, my inverter mistakenly identified my 48V battery as a 24V one, even though it continued to power the home normally.

Additionally, the data is collected via the Smart ESS application (which is a better alternative to WatchPower). However, the data is updated every 3 minutes, so I don’t believe it’s real-time. It could be a some issue that is not showing up

my shopping habit is to buy best devices from best reputation local brands

I tried to do the same, but I couldn’t manage to figure out the best option in my price range when I was purchasing my equipment (I was in a hurry to buy before the summer heat increased). I knew Deye was the right option, but it was 2.5 times the price, which would have forced me to get a smaller battery. My priority was to get a 10 kW LPBA (not LBPF).

I switched to Energy-Mate app a long time ago, which is newer and I liked it more than SmartESS. You can use the same login details for both apps, and you can even use the web app which gives you much better view of your inverter's statistics, access it at dessmonitor.com.

I believe that data is sent every 5 minutes to the Eybond servers, which hosts all these apps, so I know it's not real-time. However, providing the requested charts might give us some insight about what's happening and may let us identify anything abnormal.

It's up to you if you don't want to share any charts, but I can't be more helpful without charts or a sticker photo. Either ways, you need to monitor your solar system much closer to better identify the problem.

8-9-2024 where I has the repetitive shutdown issue 

 

 

 

- could you provide me with the webportal for energy mate ? I have its mobile app and I find it identical to smartESS but I would appreciate itcan access it from my PC

VM TWIN (III & IV) DSP 60.87 hex.zip 78.09 kB · 2 downloads

does this work with  VMIII-6000?

 

 

I currently have the 68.04 since it has fan control but its pretty dumb (am thinking of just wiring the fans to a regulator and adding 2 more as intake to control this on my own, push pull config)

 

none the less I am having issues when selecting solar only charging to where it starts pulling 8-9 amps of AC from GRID during dark and that's just insane. usually it measures around 3-4 amps with no load due to the reactive power stuff I suppose, but its still quite high.

 

I'd like a way to get it to work as bypass only during the night once batteries hit dc cut off or what not and there is no AC, to where it shouldn't really draw power while in that off/bypass state. any ideas?

Interesting charts! Do you by any chance have a multimeter or a clamp multimeter to measure real-time voltage and current of your battery, and compare your readings with the inverter's reading at the same time? I suspect there's something wrong in your inverter's readings rather than a problem in your battery.

It would be very useful too if you happen to have a monitoring platform for your battery (like every few minutes) to compare historic data between both your battery and inverter.

It should work with the TWIN variant only, which is VM III TWIN 6000W. Never use a firmware for a different model.

Did it come pre-installed on your inverter, or you re-flashed it after downloading it from this forum? What's your problem with the fans?

We've been hearing about this issue so much recently, but I'm still unable to figure out what's causing it! @Coulomb?

If you're freely willing to experiment with firmware on your inverter, I'd suggest you test a more recent firmware version for your DSP (Main CPU). You can find recent firmware versions sorted by date in Coulomb's post at:

Oh, another firmware with another confusing version number.

As Tarek said, test a recent firmware and I suggest checking the schedule of "Charger Source Priority", if there's any values rather than 00-23 in CSO, SNU or OSO modes it will override the setting in program 16.

I use a schedule of OSO (only solar) during the day, and SNU in program 16 will work during the night.

I attached a photo of how to access it.

YOU MADE MY DAY !!! thank you , I've been searching for the web portal link for a month (by googling energy mate or smart ess . sigh ) 

it is much easier to check the charts from my PC 

but I've noticed 2 things , 

the first one is there is an upgrade button in the interface ( I assume it is for upgrading the datalogger or Wi-Fi module not for the DSP , right ? , does anyone tried to upgrade this ? 

the second : I can read the parameters values from the portal but I cant change , is that normal ? does they allow reading only ?

have you found this method practical ? as I relised that it has many cons 

1- you cant change its setting from the mobile app , so if you are using the schedule programs , you cant control charging from the mobile app anymore , right ?

2-solar first has a bug that it keeps charging from solar even the charging watt is tiny and doesn't use grid till the PV voltage is 0

For me I found it reasonable, and as you said, this particular setting cannot be changed remotly.

Absolutely right, and thats why I'm using only SNU schedule starting from the sunset till the next early morning, and OSO in program 16 will be active the whole day, I've scheduled it based on the power outage in my area.

I've never needed, used, or even checked this setting before. So, thanks for noting that, I'll have a look there soon, are you sure it is working fine on VM TWIN models?

Disregard the voltage level difference between both charts. Watch closely the voltage drop in both charts, the shutdown event is not a sudden thing, there is a gradual decrease in power which indicates that it's probably not a bug. If you happen to make sure that the inverter's readings are always correct (over a few days of frequent testing), then I would suggest that it's an issue with your battery. A bug would have shut down the inverter suddenly and not this way.

You're welcome! It's not your fault, the apps are so poorly documented. I've searched for long too to find it when I first bought my inverter.

Hahaha 😁 I contacted Eybond support a long time ago about this exact settings issue, and it turned out that our inverters are not supported by their web app, unlike the mobile app which is working totally fine. I contacted them a second time about a month ago and got the same answer.

I tried the upgrade feature and it never and will never work, and from a communication perspective, never try to upgrade online, because if you lose connection while upgrade is in progress, you'll get a disaster!

Actually, from a logical perspective it's not a bug at all, it is set by design. The disadvantage of it is that it disregards how little power you are getting from your PV input.

Though, you will need to be frequently updating the schedule every few weeks to track the sunset time change, I guess, right?

I used it for four months now, and till now it works fine, no charging from grid during the day (OSO from 7:00am to 6:00 pm).

this is more clear one . the cap in the chart is where the inverter was off

what's the difference between C50 in program 16 and your scheduled? C50 (Solar First) solar only will charge your battery as it's available in daytime so in the night utility will charge it also? isn't same result ?

Correct, it's the same, but the grid power in my area is not available all the time, so if there's a limited time of grid power at evening, CSO (Solar first) will keep charging the battery from PV with a very low watt at sunset time and won't switch to grid till the PV is 0v, and at that time the grid will be out.

This is the reason of using only SNU and OSO.

If you ask me "Why you don't keep it on SNU all the time?"

My answer is "To cut down the power bill" 😁

It is a combination of resource management, available capabilities and equipment used. 🤓

your inverter has touch buttons and it's OK to update MCU FW from 57.xx to 25.xx (Do it at your own risk!)

My MCU HAS NOT touch buttons and the buttons stop working after update from 57.08 to 25.08, I don't think that factory rest will solve this problem. I'm trying to get MCU FW 57.10 to test it.

Hi

I have  Axpert VM III TWIN 4K

 

Main cpu version: 00060.10

Second cpu version: 00025.12

 

i'm using the 2nd output (twin) , set the OFF at 70% and ON at 75% , when the utility or solar source  is available the twin output stay off until the battery reach 75% percentage .while It should output solar or utility source if available based on selected priority 

 

And the monitoring app show that the battery always charging also when it reached 100% then it start decrement to 98%

The battery is lithium and pms connected 

So need the latest official firmware update that solve this problem
