March 2023, but who knows these chinese ...Yes, please share it. How old is the file? Christian
Hello,Hello all, I’ve got 2 batteries with the DR1363 software. (DR-JC03 16S 100 V2.0.1T1_G). The Chinese supplier changed some values. And I am curious what the setting of the users here are. The battery gave a OV-warning (over voltage warning). Can someone share a screenshot of the settings page on the software? Thanks a lot
I have got the same problem, but if i use maximum charging voltage of 55.2V the alarms are only seldom and it is charging up to 99-100%.Hello,
I have OV-warnings too, due to the unballanced cells. When battery is nearly fully charged, cell voltage differencies grows up rapidly and the first cell, which reaches 3600mV causes the alarm. I didn find way, how to balance the cells, so I am disconnecting solar panels when highest single cell voltage is >3550mV. BMS setting in attached files.
Regards Petr
I used 55.1V before. I am getting control on single cell voltage now and I can reach 56V sometimes. Everything depends on charging current, which is not predictable.I have got the same problem, but if i use maximum charging voltage of 55.2V the alarms are only seldom and it is charging up to 99-100%.
I think it needs some months until it is balancing the cells itself.
53.9V is too low, you can not reach full charge/or you must charge so slowly. I have no idea, how is this done in profi-made controllers, check log from my home-made controller. Everything is changing with different current, cell variation etc.I've set mine at 53.9v because of the big variation in each cells. I am clueless how to manage this BMS parameter.

Hello, this is a MOST useful thread. I have two 48V (nominal) 3 kWh batteries, working well but also throwing over voltage alarms when getting 100% charged (cell voltage difference goes up to ~200 mV, over volt protect activates and voltage difference rapidly drops to 50mV or less).Hello,
I have OV-warnings too, due to the unballanced cells. When battery is nearly fully charged, cell voltage differencies grows up rapidly and the first cell, which reaches 3600mV causes the alarm. I didn find way, how to balance the cells, so I am disconnecting solar panels when highest single cell voltage is >3550mV. BMS setting in attached files.

Hello, please where do you set the maximum charging voltage? Thanks!I used 55.1V before. I am getting control on single cell voltage now and I can reach 56V sometimes. Everything depends on charging current, which is not predictable.
Hi. I had this issue with App version DR22.04.13Can anyone help why my serial communication is not showing even though all USB rs485 are tried

I have got the same problem, but if i use maximum charging voltage of 55.2V the alarms are only seldom and it is charging up to 99-100%.
I think it needs some months until it is balancing the cells itself.
I Have the same problem .... 2 pieces of 100Ah flashed with the victron Firmware 16S100JC03-V2.0.0T1_V and run 2 Month ..... the third Pack is the Same problem.... other pinout rs485 cable and other display and version SNS09-16S100JC11V1.2.1-T3I have two LiFePO4 48V 100Ah 5120Wh from AliExpress connected to Solis RHI-3K-48ES-5G 3kW
First, I bought one battery and six months later I bought second battery.
First battery came with Ver: DR-SAIENSI01 16S100 -V1.0.3T1_G
Second battery came with Ver: DR-SNS09 16S100JC11-V1.2.1T3
First battery had different set of cables in COM RJ45 head than second battery.
View attachment 156753
Also, first battery works on baud rate: 19200
Where, second battery works on baud rate: 9600
---To fix baud rate (to have both batteries on 9600), I installed .bin config on first battery.
#Battery 1:
Ver: DR-SAIENSI01 16S100 -V1.0.3T1_G (before .bin upgrade)

Application which I used to connect was: DR22.07.06
DR22.04.13 – did not work for me (was not able to see any COM ports in my laptop)
Also attached.
---To connect two batteries I made custom cable (normal computer ethernet cable did not work for me):
View attachment 156755
Laptop with DR_App connected to Battery_1
Battery DIP settings:
Battery_1 DIP 1-6 OFF
Battery_2 DIP 1 ON, DIP 2-6 OFF
In my case, custom RJ45 cable work only in one way. RJ45 Side_A connected to second battery, Side_B connected to first battery.
View attachment 156756
Inverter cannot work with DR_App at the same time.
Inverter: Solis RHI-3K-48ES-5G 3kW connected to Battery_1
Solis battery selection: Pylon LV (Pylontech)
Battery_1 DIP 1-5: OFF, DIP 6: ON
Battery_2 DIP 1: ON, DIP 2-6: OFF
The result of two batteries in Solis inverter:
If your 1st battery is charged at 100%
your 2nd battery is charged at 50%
Inverter will see it as: 75%
You have to setup your solar charge controller to desired maximum charging voltage, not the battery. Battery settings should stay as it is.Hello, please where do you set the maximum charging voltage? Thanks!
ad a) You don't need to change battery parameters. Settings from factory is generally good. Evereyhing is about setup of your charger, which should avoid cell overvoltage/battery overvoltage.Hello, this is a MOST useful thread. I have two 48V (nominal) 3 kWh batteries, working well but also throwing over voltage alarms when getting 100% charged (cell voltage difference goes up to ~200 mV, over volt protect activates and voltage difference rapidly drops to 50mV or less).
I have exactly the same monitoring program as shown in the pictures.
a) I have now changed the Cell Voltage alarm voltage to 3550 mV and the over voltage protect to 3600 mV. Is this a good setting?
b) I would also like the batteries to charge to ~98% or so - how can I achieve this please?
My protocol version shows DR-1363 so I assume that is the same as the Pylontech?
Thanks!
Interesting. Any results?I had the same issue. China engineer told me to set this value here:
Parameters / Other / Standby Balanced / Starting V
I set: 3350 and I'm waiting for sun to see if it helps

I tried this as well (I have a terrible unbalanced 24V/200AH Battery which only charges to 188AH due to hitting overvolt protection on one cell). At least I can see in the monitoring software, that is is actively balancing earlier on now. I will report after some more charge /discharge cycles, if this did any good.Interesting. Any results?
Regards, Petr
I found thé way, how to balance thé battery! Low discharge current 2-5A until one Cell reaches voltage under 3000mV. At this moment BMS Wil do percentage correction (-9% in my case). Balancing starts somewhere around 40%, when diff>20mV, at 25% did percentage correction to 16%. After 3 cycles, everything Is Done!I tried this as well (I have a terrible unbalanced 24V/200AH Battery which only charges to 188AH due to hitting overvolt protection on one cell). At least I can see in the monitoring software, that is is actively balancing earlier on now. I will report after some more charge /discharge cycles, if this did any good.
Matviey, please tell me what cable did you use to connect to the inverter, which socket? Did you change anything in the battery?dddInverter cannot work with DR_App at the same time.
