November 12, 20214 yr Hi I have a Sunsynk with Hubble AM-2 connected via CAN. With the recent loadshedding my SOC is stuck at 80%. Any ideas? Unplugging and reconnecting the CAN cable made no difference. Switch on and Off the Hubble made no difference. Thanks
November 12, 20214 yr @swazz99jhb how many batteries do you have? and is the dip switch assigned correctly for the AM2.

November 13, 20214 yr @swazz99jhb please post the screens from your battery setup page as well - Batt type and Batt charge. You are running an old firmware, which potentially could be the issue but let’s see those settings first.

November 13, 20214 yr I have picked up a similar problem with my AM2. I have my smartload/aux set to come on at 100Soc and solar set to 0w. As soon as the inverter picks up the soc is at 100% the smartload will switch on. Randomly i picked up that the smartload was not switched on even though the battery was not charging anymore and the Voltage was on 53v - full. The Soc gets stuck and is not current. I'll leave it for a while 30min plus and then it goes back to normal.
November 13, 20214 yr @swazz99jhb Ok, some of your settings are wrong! Set Battery capacity to 110Ah Untick BMS_Err_Stop Set Float V, Absorption V and Equalization V - ALL to 53.6V Change the setting below that, from 30 days to 0 days Set Amps to 50A, you can try changing again back to 75A later, if the problem is resolved. Post the charge state (LiBMS screen) after couple of hours with the new settings! Edited November 13, 20214 yr by PowerUser
November 13, 20214 yr @swazz99jhb the correct settings for Hubble AM-2 and SunSynk are here: https://www.hubblelithium.co.za/sunsynk-hubble-setup.html

Yes but I would like to read up a bit more how that communication happens and especially, if possible for the SunSynk inverters. The manual doesn't explain that.

I updated the firmware myself. Bought the correct cable from Hubble and their tech support gave me the latest firmware file. I can share it with you, if you want but can’t take responsibility, if something goes wrong during the update.
November 14, 20214 yr @Donovanvdb, click “ activate “ under Battery Setup/Battery Type, that probably is your issue
