EG4 6000 XL won't communcate with the EG4-LL v1 batteries

I bought two new EG4 6000 XLs to go with my EG4-LL batteries. I knew I would have to update the firmware on th batteries. Signature solar sent me the correct files and firmware (atleast I hope it was the correct firmware) and I successfully updated the firmware on all my batteries. I made sure that main battery was on DIP setting 1 and it still won't communicate.

After days with Signature solar trying to help they told me that the Inverters will NOT communicate with those EG4-LL batteries. Only the V2 batteries can do Lithium Ion Comms with those inverters. I have them running ok on the lead acid setting and the proper charge parameters but it seems odd to me that they won't communicate. Signature solar was adament that those batteries would NOT communicate.

Your thoughts? Ideas? Options maybe CAN bus rather than 485. I would love to get proper comms between my inverters and my batteries. I have 9 of them.

Seems odd. The LL batteries (if they have 6 dips) should be at setting 1; if there are 4 dips, it should be at setting "0".

Have you tried the CAN vs RS485 setting? I have the LL-S and I had to switch mine to use CAN. First, set the dips to "64" and then restart battery. Then hold down the "return" button for 5 secs to enter the settings. Choose CAN, then Lux. Then restart battery and set dips back to "1".

The Firmware provided to me by signature solar came zipped in a folder named EG4-LL V1 Firmware-20231121T181806Z-001 And the hex file is named EG4-LL V1 multipack firmware.hex
If that is the right firmware, it does not work Via 485. I messed around with CAN bus but don't know what setting to set on the battery for the communication protocol. Any help you can give is much appreciated.

I believe that is the correct firmware from the naming of the file, however, I would make sure that the master battery is set to dip switch ID 1 for the LL model.

It is set to 1, and I worked with Signature solar for days and they finally came out and said oh they were wrong that battery won't communicate. SO I am desperate for some help.

Ok I got the master inverter to communicate to the first battery that I flashed. Now how do I get the second Slave inverter to not give me the sad face error. I set it to the same lithium setting as the master and I rebooted the slave inverter but it still gets an error message. I don't have a network cable plugged into the battery communication port on the slave inverter. Please Advise?

Ok one more question, I have backup system that has two of the new Lifepower 4 batteries on it. I could move the Gylls out to my Growatt backup system and move the Lifepower4 into the main rack if you think I would get the Lifepower 4's to communicate with the Eg4-LL V1 Chain?

Leave the gylls with the LLs they were made by the same engineers they work well together.

@SignatureSolarJess Markus_Eg4 was able to get my batteries communicating properly. Signature solar techs (Mr Greeley) was adament that my batteries would NOT communicate with the EG4 Inverters. How do we get this solution to your techs so that they can server your clients better?

So I assume I should simply wire the Gylls into the bus bars in my server rack and let them operate without Comms? Giving me 900 amp hours even though the EG4 6000's only see the 700 amp hours? Sorry for all of the questions.
