Hubble AM-2 SOC not going beyond 80%

Recommended Posts

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.

@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!

Done. Do I leave the CAN cable in? Thought all that stuff gets ignored if CAN is used.

If you have BMS communication between battery and inverter the bms does everything,its pre-programmed on the bms. 

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.

Do you guys updated firmware yourself? Where do I get details on it? I have usb-serial converters I use to flash Sonoffs. 

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.
