@sm133 Your inverter supports BYD CAN. We can stop discussing anything in this PR related to your troubleshooting, since you will not be able to use Sungrow CAN. Please make a new Issue for troubleshooting your install: https://github.com/dalathegreat/Battery-Emulator/issues I will be deleting all comments from here, since this PR focuses on integrating Sungrow CAN, not on troubleshooting your BYD_CAN install. |

Hi @dalathegreat, I am happy to test this now I have my hardware in place. I am running a Tesla M3 82kwh Battery (penhouse fully intact) with Sungrow SH5.0RS Inverter. I have 10a fuse for capacitor (outside penthouse) and 32a for pos and neg from HV to Inverter. Battery contacters are proven to work. I have not attempted connecting Inverter yet, but I am ready to do so. I have setup a single Lilygo, but I read sungrow and leaf battery do not work well together given sungrow's 'bug'. I am not sure if this would be applicable given the M3 Tesla battery has a penthouse that is the brains for the battery, I would think the penthouse would protect the battery anyhow. Though of course I can install a CAN-FD MCP2518 board. What do you recommend for this test? |
