Charge Controller Block:
This block is usable for most OutBack charge controllers with the exception of the OutBack MX60. It is
a status-only block and does not contain command or control fields.

Charge Controller Configuration Block:
This block always accompanies the Charge Controller Block. It is usable for most OutBack charge
controllers with the exception of the OutBack MX60. It contains command and control fields for the
charge controller, as well as vendor-specific status fields.
