Hi there.

 

I've recently had a Sunsynk 12kw 3 phase invertor installed with 2 x Hubble AM-2 (5 kw) batteries.

The system is "working" however the data seems all over the place.  The installer originally had the invertor and batteries connected via the CAN bus but we were seeing all sorts of odd scenarios - PV showing 0 during the data etc..  Anyway he came out yesterday with another guy (he said he was from Sunsynk but not sure..) and they've now removed the CAN bus and said the Hubble with Sunsynk 12kw don't play so nicely..

Although everything is working the battery percentage is not accurate/reflective of what is going on.  Eg 6am the Sunsynk was showing 22% but the Hubble had 3 out of 6 led lights on.  

I just looked now and the invertor reported 0% with a voltage of 45.8 (see attached). 

The battery setup on the invertor is set to AGM V - which seems odd given that these are lithium..  However they tell me this is what it should be set to!  Since they are the experts I guess I'm trusting them - but also a bit skeptical..

Can anyone offer any advice / suggestions?  Not sure if I should be buying the Hubble cloudlink so I can monitor it better - although not sure what I then do with the data?

 

thanks.

 

 

 

 

Those voltages are very high for a Hubble.

When set to AGM V, the SoC won't be as accurate.

Sorry - which voltages - the setup numbers?

Are you suggesting I should be using AGM %?

I am not suggesting that - ideally it should be set to lithium, and use the BMS, but due to issues with the BMS, that does not always seem to work as expected...

Hi Craig , I had the same problem, updated the SunSynk software to M 2005-1121 S 18-07 C1001-E030, working fine now

Thanks. 

 

Can you share your settings and setup?

 

I'm running the following - which I assume is an older version of firmware than yours?

M 2005-1116 / S  18-07 / C 1001-E02A

Yes it is older. Mine shipped with this firmware that you have. 

I had weird data showing on the non-essential loads.

The latest one is: M 2005-1123 / S  18-07 / C 1001-E030

Thanks.  And are you running with the CAN cable without issues?

Yes I have different batteries to you. I had a W31 warning intermittently but that is sorted. Try updating to the latest firmware and see if you can run your batteries through the CAN port.

I've upgraded the firmware and have gone back to the CAN link setup.  Everything has been ok for the last couple of days but when scrolling through some of the screens I can see that the battery capacity has dropped.  Why would this be?  And where is it getting this number from?  The settings in the invertor are 220.  I've tried changing them to see if it makes any difference but it doesnt.  I'm also not clear on where the SOC numbers come from - if using the CAN are they always coming from the battery?

 

thanks.

Did you upgrade the firmware of the SunSynk or the Hubble-AM2.
When I "upgraded" the firmware of my AM-2 they went from 110Ah down to 100Ah 😞
I then did a newer firmware and they went from 100Ah to 105Ah.

THe firmware upgrade was on the Sunsynk.  I've subsequently restarted the batteries - just turned them off and on and it has gone back to 220.  Has been stable.
