I'm trying to figure out how to take advantage of the tank monitoring capabilities in the CCGX. I know for resistive sending units I need the VE.Can resistive tank sender adapter... My only problem is I have three tanks (Fresh, grey, and black) and these adapters cost $400 each!!! I would end up spending more than twice as much on these "adapters" as I have invested in the CCGX itself.
So I started looking at options. For RV holding tank monitoring: SeeLevel II is pretty much considered the standard for high end monitoring. When i was looking at their product offerings I noticed they have sending units that support "RV-C" which is a CAN Bus based protocol. Since the VE.Can adapter simply converts the resistance it gets from the tank into CAN Bus messages... If the SeeLevel II sends CAN Bus messages to begin with then it *should* be fairly straightforward to just connect these to my existing VE Can bus (I already have a CAN bus between the CCGX and my Orion Lithum BMS system)
That's assuming that the RV-C messages sent by the SeeLevel II are compatible with whatever message format the VE.Can adapter sends. I'm hoping someone from Victron can help me out.
