Hi, I am using a LuxPower SNA5000 with HOSELECT 4.8kWh.

My issue was that suddenly the battery would report 100% SOC at less and less voltage until it would not charge past 48V.

Unfortunately I bought this battery from the wrong people. The guy I'm talking to is a HUGE @$$ and obviously nothing more than a salesman. Makes me wonder if selling this type of equipment should not require a green card - he does not understand the difference between Lead Acid and Lithium, or what a BMS is. So I am on my own here.

I've manually charged it up now to 53.3V (pack voltage param in pbms) using a Kodak inverter with user AGM settings (was unable to get it to communicate with BMS). Now back on Luxpower after 3 cycles it seems to be charging fine again to the proper voltage.

Now my question, does anybody know who I can contact with regard to obtaining a firmware update for this battery? The sales guy obviously won't help and I am unable to find any information on Hoselect batteries.

Current firmware version is P13S120A-21347-1.0.0.

Maybe it will work properly now and an update might no be necessary. But as I said it happened gradually so I will keep an eye on it, but want to be prepared with an updated firmware if an one exists.

 

Cheers!

Hi Chris,

How did you manage to see the firmware of the battery. I have installed three of these batteries with Luxpower SNA inverters in three different installations with now problem and now the last one is completely different. Where I used to select battery brand 21 I need to select brand 4, and where all the other batteries is fully charged at about 52.7V, this one only reach about 77% SOC at 55V and then does not want to charge any further.

I am trying to connect to it with PBMS Tools through the RS232 port but it simply does not want to connect. Did you manage to connect to it?

Hi Chris

Were you able to figure out what the problem was? I have a Growatt and SVolt with a similar story. Battery says it is at 97% but voltage is 42.25v and then shuts down. Have had the battery swapped out for a new one and now 2 weeks later its the same thing again.

Sounds like communication issues causing SOC drift, probably because the battery is not fully charging and balancing. I would suggest disconnecting the comms cable between battery and inverter and switching the inverter to a USER mode where you can enter the charge voltages and charge the battery to 53V and see if that can get you back to a proper 100% SOC.
