aolithium battery settings

[Rburnham11]

Hi all.
I'm looking for help with the aolithium 51.2v rack battery settings. I'm using a voltacon 11kw ultra max inverter and have been using it with agm batteries up till now. The inverter has various settings for different lithium batteries like pylontech ect but it wont connect to the bms in the aolithium battery. If i select any lithium settings it goes into alarm mode as no bms connection. I can use the user defined settings and it seems happy enough but am unsure of the best settings for this. As you can imagine aolithium custer support wasn't overly helpful especially due to language being unclear. So questions are, is there a way to have this inverter and the battery bms to work together? if not, using the user defined settings could somebody help choose the best settings for this? I have attached a picture of the adjustable settings.

Any help would be very much appreciated.
Thanks
Rich

That unit looks like a voltronic-type unit... if that is true then Try this?

I finally found out how to get the AOLithium Server Rack battery to communicate with Voltronic inverters over RS485.

You need to flip only the first DIP switch on and leave the others off then set the inverter battery type to LI-b instead of PYL.

The kicker is that the BMS will only read the data from 1 battery.. Data from any slave packs are not included in the RS485 data stream.. This only possible with the CAN-BUS output which explains why Luxpower and others have no problem.

And as mentioned above make sure you have a network cable made up with the proper pinouts. I don't know why...
