Hubble Batteries

At least once every 7days. I did find something once, let me check.

Don't just watch SOC. The damn thing drifts vs battery voltage. A full charge means your battery voltage needs to be around 53.8V The bms only stays kicking in around the 53V mark from what I know.

Use whatever app or monitoring to check what your voltage is at the 100% market.

Do you have the latest firmware upgrade that you can share for the AM2?
 
Im using 3 am5 batteries, with solar assist, and it will only see the first pack, do i need to get the cloud link thing to get more info? On the inverter, under the BMS section, it seems to also only show the one pack, using the can cable if i recall correctly

Is SA connected directly to the batteries, or via the inverter?

There is a cable going to the sunsynk and one to the batteries (rs232)

With this

SolarAssistant

solar-assistant.io solar-assistant.io

Connected to the primary battery ( as mentioned , the link between inverter and battery is the canbus )

If I had to guess, the inverter, although charging for 3, also only “sees” the pack as 1

Unless the bms’s consolidate and average it all
Out for the inverter

The batteries need to have LAN cables wired between them on their Battery comms ports Master/previous Battery Port2 -> Next Battery Port 1,and the DIP switches ordered correctly in order - SA Wired battery as master 1,then 2 3 4 5

Need to double check the dip, I made up the can cables as per hubbles instructions


That said, below is what solar assist had to say about the dip switches

If I recall, its very important to get the battery dip switches right - it affects balancing.

That 300A charge current limit makes me think that the config is correct

Without the dips they can't individually be read,it's a thing

Still going strong with hubbles August 2022 installed.

Still have not added additional batterries. Will see how 2024 goes.

Mine also seem good, some random **** happens occasionally with the readings from SA - but - I think its SA, not the batteries. EDIT: Gonna hit 700 cycles soon - since November 2022.

My only dissapointment with SA is their lack of fixing issues timeously. (unless you want to use beta - which I don't)

and the notifications.. that have been coming "next month" for the last few years :D

other than that, its leaps ahead of the sunsynk crap app that comes with the inverter

Thank you, tonight I powered they whole thing down, fixed the switches ( guessing installer) ,


Powered up, and just like magic, the data is there z:)
 
Not sure why my hubbles are not balanced in 'charging/discharging'. The newer one always takes the hit

Sandton has a area outage and so it meant we were running on batteries (not even fully charged) since 4PM yesterday. The system finally failed at 6:50AM ..

But look at this now that it is back up.

1st Original Battery

2nd battery - installed a year later
1711524188302.png

So when the system shutdown finally at 15%, Battery 2 was at 4% but Battery 1 was at 27%. Battery 2 cycles faster than Battery 1

The cables are fine and equal length and go in the loop from inverter to battery 1 to battery 2 to inverter. Voltages are matching each other.

Do I just accept this as normal or do we need it to be checked?
 
That's a huge differences - I have four, they frequently get out of sync as they get lower, but - max is usually about 12.5% difference.

I actually made a sensor to track it MAX acrosss all batteries less MIN across all batteries.

3 of my batteries arr 131-132aH - and one is 122ah - its usually this one that causes the fluctation - but - not always.
