Good Day,
I take great concern in the Hubble AM4 lithium battery issue I currently face with respect to an over voltage issue . Victron you have this battery as a compatible on your website but in my case its been 3 weeks and Hubble Lithium energy has not fixed the issue.
Setup:
3 * Multiplus in parallel (3000/24/70)
4 * 250v/100 MPPT Solar Charge controllers
2 * Hubble AM4 battery packs.
Cerbo GX
From the day of installation the victron monitoring detected an over voltage alarm . I noticed the battery volt SOC at 100% read 29.2V .
As per Hubble Lithium documentation the battery should charge to 29V .
So the over voltage alarm is connect.
Hubble said i should upgrade the battery firmware, I purchased a recommended cable and obtain the software from Hubble Lithium and upgraded the software. This made no difference.
They then said there cloudlink device needs to upgrade by them , still no joy.
Now my VRM cant offer me any alerts as the api maxes out due to the hubble being in overvoltage alarm .
Hubble cant seem to able to access there own BMS to cut of the SOC at 29V . I even asked for access to the BMS to do this but they are mum on the matter. 12 emails still nothing.
A 26000 ZAR investment on a Compatible battery as per the victron website has proven to be a bad one.
Victron can you offer any assistance or perhaps re-look at this being a battery on your list.
