Hubble Batteries

There was never a time to default to that for AM2 - they could have just read the battery label,those are very specific to LFP values too,maybe they assumed it's an LFP not NMC?

Rather annoying then... fortunately it would have been resolved if I actually did the above post.

Can see why mines was set as 53.6, because it's the same as @xrapidx label and that's what my installer used , even though the comms protocol is BMS.

Still have no Eskom grid (fsck eskom) and the batteries got down to 10% overnight and battery 2 was at 4% and batt 1 was at 35% or something. I will do the 0 test when I get back home.

This is the SoC history overnight.

The voltage of both batteries are identical

What is your SOC Cut off?
Does anyone else set their SOC cut off so low?

I have my AM5 set at 23% SOC Cut off.
 
If you're using comms, you guys do realise that the voltage sessions only come into play when something goes wrong, like a rat eats the cable?

Okay, but we are trying to get to the bottom of this "issue":

I set it to 2% in the last two days (previously 15%), as it's now two days with Eskom and I need the two batteries to last the night (and also bring them both down to 0% for the one test.

I am in europe at the moment , and it's driving me mad that my family is so compromised. Eskom resolved the ticket but nothing was resolved. I travel back on weekend and will aim to do all the tests first doing the @xrapidx recommendations from Hubble

Ah ok, I know Hubble indicates SOC 10% safely, but I'm just overly cautious and set it to 23%.

Eish, sorry to hear man. Was in a similar boat last year.
The wife and I were away on Pilgrimage and the Kids whatsapped us to tell us there's no Power (6am the morning here) 8am where we were. I checked the App and the battery had died round 3am.

This was before we had solar, we just had the Battery and inverter. Luckily it was just a dead phase on the city supply side. So the battery lasted from 4pm the day before to 3am that day.
 
Still no Eskom power.

Came home to find the incoming Eskom feed into house junction box had blown/burnt up. How the fsck a cable box that has not been touched in years does that beats me

But last night the entire area was without power , but apparently when they restored it , was when she heard an explosion. I guess it was that junction box.

Thanks man. Waiting for an electrician to come tomorrow, and hoping it's a cheap fix - ie only junction box and no need to run a new high power cable from 20m outside into the house (which is tiled, grassed , paved) , to get to the same place.

The Hubble batterries are doing a stellar job even with their wierd SoC differential, and the crazy weather (ie nice and sunny ) has helped us keep the lights on all the time.

Will only do the tests when I have grid power afaun

I keep eyeing the official cable I bought from Hubble to connect to the batteries lying on my desk.

Too scared of connecting it to m y Am-2's and opening up PBMSTools to find something weird going on with them. According to the limited info Solarman gives me they are fine. And according to the Riot.
 
Everything was smooth sailing got home now and I see one of the batteries appears to be totally off. No lights nada niks but "on" switch is on. Portal says there is 3 not 4 batteries.

Will give hubble a shout tomorrow should be no issues as no load shedding and nothing has been "different" any ideas?

Reset and on off did not work

Technician will come out Wed will feedback on the experience then all good so far

R980 for call out and first hour I can live with that they will deal with everything
 
Rather book it in.

One of my batteries gave me kak 2 years ago, booked it in.. 2 weeks later they gave me a new battery

So, grid issue fixed. That burnt out junction box was thankfully easily repaired even if the cables were tight. R1k for the job. Shew!

Since at 6pm last night we only had 69% SoC and really ran the house on lean mode i.e 300w.

This morning, knowing electricians were coming tried to flatten both batteries before solar charged them up.

Shutdown on inverter was set at 2% and I was trying to run every high draw appliance in the house. Home Assistant and my automations - made sure the house conserved battery so I had to disable some of them to klap the battery.

What I noticed in the tests -
Hubble 2 was at 0% for a while, while Hubble was still had 24% when I started trying to flatten the battery. Soc reported was what Hubble 1 had left.

While I have battery discharge only at 150A (can be 200A), I saw 5.75kWh of draw going through them so that was interesting especially since only Battery 1 had SoC.

Hubble 1 went down all the way to 4% SoC when the inverter shutdown. Voltages across both batteries even Hubble 2 at 0% SoC matched all the time.

Now I see a 3% differential at the moment, this is them now charging up after inverter restarted and will see how it goes and will see if that sticks to a 3% differential or they will sync up after getting to 100%
