Hendrik Roos Posted May 3, 2022 Posted May 3, 2022 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. Quote

Hendrik Roos Posted May 3, 2022 Author Posted May 3, 2022 Useally it charges full,except for when we have bad weather but the weather was good today. It charged to about 73% Quote
zsde Posted May 3, 2022 Posted May 3, 2022 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. Quote
Hendrik Roos Posted May 3, 2022 Author Posted May 3, 2022 Im also on 20% daily. Set it now to 10% just to make sure im getting through the night with these loadshedding. Quote
werner.potgieter Posted May 3, 2022 Posted May 3, 2022 Could possibly then be part of the supposed batch issue of Dec2021-March2022. Probably best to reach out to your installer or Hubble-support. Good luck... hoohloc 1 Quote

Hendrik Roos Posted May 4, 2022 Author Posted May 4, 2022 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. zsde 1 Quote

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. Quote

I wonder if you can downgrade firmware? 23 minutes ago, Hendrik Roos said: About what would I speculate? 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. Quote
Hendrik Roos Posted May 5, 2022 Author Posted May 5, 2022 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. Quote
TimCam Posted May 5, 2022 Posted May 5, 2022 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:- https://www.solarquotes.com.au/blog/solar-inverter-security-hackers/ and https://diysolarforum.com/threads/sol-ark-needs-a-serious-change.27144/ Note Sol-Ark is American version of SunSynk. hoohloc 1 Quote

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. 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. Quote

Hendrik Roos Posted May 6, 2022 Author Posted May 6, 2022 Found the problem. Faulty Inverter and not batteries. Just my luck,will get the "DAT" out of the batch.lol Quote
