Thanks. Unfortunately this doesn't seem to work. Currently the battery voltage is 52V according to shineserver. But battery % reported by BMS is still 0%. I let the batteries drain and charge and it remains 0% all the time. Not sure if the comms cables are correct or not. Perhaps I can leave it on user defined but then need some guidance on the correct Voltage settings for: Charging Voltage Floating Voltage Back to mains Mains To Battery Battery Manual has these: Charging Voltage: 54-56.4 Nominal Voltage: 51.2 Discharge Voltage: 45-48 Link to document from Shoto. I have the 16 cell 51.2V battery. Actually 2. http://www.shuangdeng.com.cn/userfiles/4cd5d807dc514b838f58401c8f3a3e9f/files/锂电系列/SDA10/SDA10-4850（En）.pdf

Hi All I have the following and just can't seem to get growatt or Shoto to assist. Growatt SPF 5000TL HVM-P with latest firmwares loaded. 2 x Shoto SDA10-48100 (5.12Kwh) Batteries Batteries are connected as per manufacturer including the RS485 cables provided for BMS communication between batteries. According to manual RS485A port on 1 Device and RS485A Port on second device. Dip Siwtches are set to 1 on and 5 on on second device. Straight RJ45 cable is plugged in on CAN port on Battery with dip switch 5 and on BMS port on Growatt inverter One advice I did get from Growatt was that I should use RS485 with Option 36 set to L07. I have done this and it appears that it is talking as I am not getting error 20. LIT icon is on next to battery. Only message now is warning 04. Low battery. Shine server is reporting SOC as 0% According to SOC lights on batteries themselves = 50%-75% charging. I am not sure if the comms are correct or if I am missing something. Any guidance or advise on what to check will be greatly appreciated.
