/* Sol-Ark v1.3 protocol
|
||||
The Sol-Ark inverters only recognize standard CAN Bus frames containing 8 bytes of data.
|
||||
CAN FD with 64 data bytes per frame is NOT supported.
|
||||
Communication Rate: 500 kbps
|
||||
Data Endianness: Little Endian (least significate byte is at left end of multi or 2-byte values)
|
||||
Transmission Cycle Rate: BMS full data set here shall be transmitted to the inverter once every second.
|
||||
BMS sends first message with this full register set. Inverter Heartbeat Response: Each time the inverter
|
||||
correctly receives data, it will respond with CAN ID 0x305 containing “00 00 00 00 00 00 00 00” as data.*/
