Good day.

I have a 8kw Sunsynk Hybrid Inverter with 3× 5,5kw/h Hubble batteries.

Suddenly today it does not want to charge fully and the Inverter only gives power to what is needed and dont send access energy to the batteries.

I did not change any settings and yesterday it was still all fine.

Hi. What percentage is it charging to.

Suggest you peruse this thread that has been discussing similar issues. Supposedly both Sunsynk and Hubble have released or are in the process of working on Firmware updates to address these issues.

Thanks for the advise.

Hubble is sending a person out tomorrow to test the batteries to see what is wrong.

Must say so far its good after sales service I got from Hubble.

Phoned 3 times today to help with settings and to hear if the person/technician made contact and so on.

Speculation, no proof!!  Maybe someone is hacking inverters and/or batteries through the Solarman dongle and app?

I have never used the Solarman dongle on my SunSynk 8.8 kW inverter, and only gone online with Solar assistant two months ago.

My two Hubbles are still perfectly happy, and fully charged after a bout of load-shedding, or maybe I'm just fortunate.

I'm using the SunSynk dongle.

Possibly a firmware update on the inverter causing trouble? I wonder if you can downgrade firmware?

Nope, I'm speculating, as you said you did nothing from one day to the next, but suddenly the battery wouldn't charge.

So if there is no hardware fault, and you changed nothing, maybe something happened remotely via the internet connection.

Nope,also not a firmware update on inverter.

Sunsynk also did an update and it is up to date.

When I set it to AGM V it shows about 54v bit when I test it at the breaker it says 47v.

Believe it or not but Sunsynk is just as puzzled as the Installer.

There is basically not a thong that we have not set or tried on the inverter.

 

Only possible scenario is that it is a hardware problem.

I have never updated my firmware, and am running COMM e418 MCU 3878 for a year now.

My motto is, if it's not broken, don't fix it. :)

Never had problems from day one with this "old" firmware.

See if SunSynk can downgrade to this version, and if it helps in any way.

 

On the Hacking front, have a read below:-

and

Note Sol-Ark is American version of SunSynk.

Seems your Hubble-AM2 batteries are from a different batch "for a year now" than the problem batch.
Mine were purchased in Oct 2021 and installed 12 Nov 2021.

In terms of:
hacking
   I'm not convinced that hacking a SunSynk would affect the SoC on AM-2 battery.
   Hacking is unlikely the cause of the AM-2 SoC issue as we all have different network routers, dongles (SunSynk vs SolarMan)
   TIP: Use a different "guest" network for your IoT
   The diysolarform article is a "red peril" anti China rant and deserves no consideration.
   The solarquotes is good and has some valid suggestions.  These suggestions are for all IoT equipment (eg your TV/PVR/Printer/Inverter/etc)
don't upgrade firmware
   applying updates is a good & recommended security practice
downgrading firmware to "old"
   Not sure how downgrading firmware on SynSynk would fix SoC issue with the AM-2

I've used a Python App, Solar-Assistant, SunSynk LiBMS and RIOT to view SoC & Volt values from the AM-2.
All show the same degraded SoC values for Volts which indicate a problem in the AM-2.

This graph below shows what the Hubble BMS SoC (RED) reports vs SunSynk AGM-V SoC vs Juntek SoC / Ah shunt.
image.thumb.png.06ca9428ff4d349bcd687666bbf2a844.png
The Juntek is a coulomb counter / meter and matches closely with the SynSynk AGM/V SoC readings.
In my case, I'm missing ~72Ah/18% when using the Hubble BMS SoC.

Hopefully a fix will be provided by Hubble soon.

If it is a "problem batch", hope it gets sorted soon. 👍

Found the problem.

Faulty Inverter and not batteries.

Just my luck,will get the "DAT"  out of the batch.lol

May I ask how you figured out it was the inverter? I may be sitting with a similar issue, but with Hubble AM5's
