@Muzammil, have a look here, this is the same battery as you and it seems they use a different software to access it that does both RS232 and RS485. He has the cables etc. working, but the seplos software didn't connect, I guess it needs different software, maybe PBMSTools will work.
 

No problem, here is the manual I have for the older battery which has info on the RS232 port in case you don't have it. The manual does say that the RS485 ports can be used to communicate with a PC, so it should work if the seplos software is the correct software.
It also says the RS232 port can be used with a PC, I'm just not sure if the seplos software supports RS232 or if it is only for RS485... that's why I suggested PBMSTools as I know it works on RS232 and seems to work with most BMS, it might be worth a try if you have exhausted all your other options.

Yeah I think so too, it also has the dry contacts shown in the manual I posted which the new battery doesn't have.

Thank you for detailed response. I have set the bulk charge at 54.5V and float at 52.5V. Back to Grid is at is Battery Stop discharging when grid is available. Its at 51V by default in my Invetor setting. I will check the charging behaviour and update you. thanks again
