Cant see this on the app, it usually charges to 55.2v (@100% SOC).
Only if I change the battery to Lead Acid then I can change it.

Yeah, I think you need to set it there and then change back. 55.2V is only 3.45V per cell and is not high enough to get to the knee in the curve to balance properly imho. I would set bulk/absorption to 57.6V and float to 55.2V.

Why are your voltages at 55.7 ? Shouldn't it be 53.6/7 for the Hubble AM2s?
Definitely should charge mines back to 100% tonight.
If I wasn't leaving country, would add 8 more panels and 1 more battery to the system and then I think Eskom use would be minimal.
Since I have a deadline to be in the next country by Jan, if it doesn't work, hope prices remain as low as possible

I thought it’s AM5?
Can't, at least not on the APP:
But, if i change the battery type to Lead Acid on the Inverter, then the option to adjust the Voltage comes up.

Yeah, I think it uses the lead acid values for the lithium setting.
Correct, as per LUXpowers Settings for Hubble: https://www.hubbleenergy.com/_files/ugd/ece034_877708ee89d64721ad3df70716236b23.pdf

I guess you can leave it there then, not much capacity anyway after 3.45V.

Have a gander at this:
HAHA, Thanks, I actually saw that yesterday whilst I was still in panic mode and googling myself into a coma.
Confused the **** outta me, because it's different to the Hubble recomendations.
But then I saw those are also diff to the Hubble / SunSynk recmd'd settings. --> Hubble /SunSynk Settings
I'd much rather err on the side of caution and stick with their recomended settings.
In the event of a warrany claim, they can't ever say I exceeded their recomendations.

Did you get any manual with AM5?

That isn’t necessary imho, 57.6V is enough to balance properly, even 56.8V.
Maybe do it once to get a proper balance then use a lower setting.
Although we have no idea when balancer kicks in.

Back just after it was installed, i was concerned about the "float" at 99% soc.
Emailed hubble, and they replied...
I've never messed with the charge voltage.
Normally, it charges to 100%, stays there for about 20 mins, then drops to 99%.
But ive never monitored the Vdc at float.
Will do so going forward.

This sounds fine.
Small update. Battery is performing exactly as I expected.
Yesterday it charged to 94% SOC @ 55Vdc.
Discharged it to 23% again overnight (I had set it to 15%, but forgot I had "Force discharge" on, so it used the "Force Discharge" parameters which was still 23%).
This morning it recharged from Solar to 98% SOC @55Vdc.
Will discharge again tonight as normal, and suspect it will reach 100% SOC tomorrow.

What irks me, is that sunkynk occasionally shows the battery SOC% incorrectly. But viewing the battery voltage in the apps shows its floating around 53.6/53.2, yet the sunkynk app show 84% SOC.
I'm assuming hubble balances using the BMS? Most likely it uses passive balancing which imo is not that great. I installed active balancers on all 6 of my batteries. They are custom or DIY built though..
