Hey Everyone, 

 

Just reaching out for some help please. Im not sure If I should contact @HubbleLithium for some advice here or should there be something else I should be trying to fix this myself? These AM2's were installed 4 days ago and Im noticing some weird numbers with one of the banks on SolarAssistant. Could anyone who has gone through the same with these batteries before? 

 

 

 

Kind Regards.

The SOC/Capacity numbers can be a bit odd till they've been fully discharged and recharged

Also are your voltages set correctly? (Take a look at the sticker on the batteries) That voltage seems a bit low for "fully" charged

Thank you for the time @PsyWulf

 

I am doing my homework at the moment with everything as we speak as well. Im currently busy with the reset - https://hubblelithium.freshdesk.com/support/solutions/articles/151000003441-how-to-reset-comms-at-100-soc to get the 100% SOC. Im then going to go through the Hubble Sticker and align the settings on the Lux. 

Okey going better, SOC is up. Just waiting for the voltages to now align. Im learning

 

You can set the Bulk Charge to 53.6 and Float to 52.6

There can be some variance between the 2 batteries,it balances out eventually

Assuming you mean when Im back on the Lithium setting after the balancing correct (confirming first)? Ill do that then thanks @PsyWulf

I am also a bit unsure about the correct voltages as on the @HubbleLithium website the setting given is 53.6v for both float and bulk charge as to the setting on the battery plate shows float to be 52,6v. A bit confusing .........

Iv gone and added that to my support query to for clarification. Ill update when Blake replies. 

There's some variance on the Hubble Batteries that come out,between 100/105/110Ah capacity and the voltages

I tend to set mine to what's on the batteries

Yeah the only crap thing about that, is they altered them via software updates so even when my says 110ah on the battery and sticker, thats not what SA reports. 

 

Ill check with Blake and confirm.

 4 days and 6 or 7 cycles already... are you draining the batteries to 20% SOC every day? If not, keep an eye on those cycles, there have been issues with how they are counted.

Im not sure what I can do to prevent that? I only have the batteries for a backup solution so no panels are connected. This morning its reading 8 cycles already.

There's not a whole lot you can do yourself except document the amount of use and how the cycles are counted and present that to Hubble if it is not working properly as it affects the warranty criteria. The more people that do this will help prompt them to fix the issue. It won't affect battery performance at all though, it is just a counter.

Thanks. I was curious what the Cloud Link would report as I heard they show different figures too but not going to pick that up just to count cycles. Ill keep an eye on it, thank you for the pointer @jumper. 

Struggling more than I would like with this setup.

Not ideal...

I have the same issue.  New AM2 battery, only drained once to about 58% but shows 8 cycles

fyi I have found a setting in the bms of my shoto battery that is incorrectly set to count a cycle at 20% cumulative discharge. If you find your battery is also counting a cycle for every 20% then it is likely the same issue.

Im really at the point where I wished I went for the DYNESS 5.12KW kit. I just cannot get these two balanced with the Lux. I have opened support queries with them but its just a distasteful experience on a 56 000 set of batteries.

What exactly is the issue now?

This is my start of the day

So Im only using my setup for Backup power at the moment till we can run with solar later down the line. I dont have any need to discharge them other than during loadshedding. So since I got the battery, pack 1 was not hitting max state of charge and was constantly behind pack 2. I then done the whole AGM setting to balance the voltages and get both banks up to 100%. I did that yesterday, that worked great. This was after the balancing. 

 

The LuxPower then when connected back to Lithium mode immediately started to discharge the batteries, despite the AC charge being 00:00 till 23:59. Seen in the above image by the "draw" happening on both banks. 

 

So I left it thinking its the BMS resetting things. This then happened the entire night, up and down which doesn't look like its expected? 

Anyways we had load shedding twice this morning and again the batteries are unbalanced by nearly 5%. 

 

 

It just doesn't seem right @PsyWulf

Just some things to keep in in mind with these lithium batteries as they didn't work as I expected at first, coming from lead acid... this is from figuring out my own bms, but they seem to operate much the same.

Once the battery reaches 100% SOC the bms will put the battery in standby and only allow discharging until 96% SOC and then will allow charging again.

These Axpert type inverters will always draw their own self consumption power from the battery, never from grid, there's nothing one can do about that.

If one battery is always out of sync it could be the battery wiring. How exactly are they wired to the inverter? Both cables from 1 battery or 1 cable from each?

Thanks @jumper. Im going to look at the cables shortly and post back here with a bit of a drawing. The up and down is weird for me when I look at the charts when I first installed the entire setup. The stability/lack of draw up/down last week looks drastically different to the up and down thats happened in the last 3 ish days.

😠 😠 - Cables are a shit show with how its all wired up! 

 

@Leshen helped me on a call quick sticks! Wow what a gent!

I see what you mean with the difference in the chart. It could be due to your changing of voltage settings etc. It may also have to do with changes in weather if you are charging from PV.

Unfortunately I don't have such detailed reporting on my system so I can't say if this is normal or not. Hopefully someone else with SA and Hubbles can comment.
