Growatt 5000es not charging my lithium battery when its low battery ?! why? i had to reboot so it charge again

Yes using the pc app

for gorwatt spf 5000es what what is the protocol we should choose can 51 or can 52

did any one know the cable diagram ?! for gorwatt spf 5000es

i can use the pc software only when i set the DIP switches to RS485 .. while deye use CAN is that normal ?

so the inverter should only see the master? as deye have options to show voltage per pack.. and it show only the battery (Amps used) only of the master and not by the slaves so if am using 10 amps dc.. it show only 5amps (as they are 2 packs amps is divided by two..)

i did exactly.. but i dont know why deye is not reading that i have two battery ...its reading BMS1 only :/

please may i know how to connect to parallel ? as deye is reading one bms only i have the the address of the main battery (5 on) and the 2nd battery (1 on) and connect the both bms using ethernet cable no success
