Sungrow recently pushed out a firmware update to their Wifi dongles that use an encrypted modbus comms method.
A user on Whirlpool has successfully figured out how the encryption works, we'd just need to subclass ModbusSocketFramer to implement the encryption/decryption and discovery of the inverter key (assuming it's different per inverter).
