June 5, 20197 yr Does anyone have Sofar me3000sp with more than 4 pylon us2000b batteries? If yes - what is “Battery Capacity” that inverter reports in “System Information” menu for you? On my system it shows 200ah - should be 250 for 5 batteries.... confusing! Do you guys see more than 200ah? Cheers 🙂
June 6, 20197 yr Author Found the problem: Sofar allows you to connect to pylons using RS428 or CAN. After adding 5th battery - Sofar could not see it when connected wia RS, but when I switched to CAN problem was resolved.
June 7, 20197 yr Just for the info: CAN implementation in Pylons automatically broadcasts the summary data for the whole battery group. Therefore it's very easy for the inverter to work with the values. CAN will work okay up to 8xUS2000. Even when you add another pile of 8 batteries and combine all 16 using Pylon LV HUB, CAN will send the total values to the inverter. RS485 protocol in Pylons is much more complex. It offers tons of details, down to an individual cell level. Therefore, the inverter itself has to implement the summarisation logic, brick and cell addressing etc. Looks like Sofar did not implement this logic completely now, but this might change in the future FW versions...

Makes a lot of sense. Thanks mate
