20.1.8. RV-C Device Priority
A critical concept in RV-C is the application of Device Priorities.
When used, a given device's priority will impact if it is allowed to transmit DGNs (e.g. a BMS with a higher priority should transmit
details of the battery's status, while a MPPT controller with a lower priority should back down).
Device Priority is also at times used to allow for the favouring of one node vs. another, for example, it may be more desirable to
use shore power AC vs. the inverter.
In the implementation of dbus-rvc, the following priorities will be hard coded into transmitted messages:
• DC_SOURCE_STATUS_xx messages: Priority = 119 (SOC/BMS) to allow native RV-C batteries have a higher priority.
• SOLAR_xx messages: Charger Priority = 110
• CHARGER_xx messages (Inverter/Chargers):: Charger Priority = 100
• CHARGER_xx messages (AC Chargers):: Charger Priority = 80
