Accurate monitoring of DC power consumption

I have a pretty small Victron system installed in my travel trailer:

  1. Cerbo GX & Display
  2. Victron Smart Batteries
  3. Lynx input and distributor
  4. Lynx Smart BMS
  5. two Multiplus for the 50 amp service

I just added a SmatShunt to from the Lynx Distributor to the RV DC system:

img-0118.jpgWhat is up with the difference between the estimate and what the Shunt is showing? Is that what things like the Cerbo, three MPPT's, Multiplus (even though they are off), are consuming?

I do have GUI Mods installed, is there any way to get the system to show both on the main page?

Is your shunt configured as a DC meter? Looks like the mod isn't drawing its information from it.

I do have it configured as a DC meter, not a battery monitor. I assumed I would have to go into the Cerbo somewhere and tell it what type of DC Monitor it is, but I have yet to find that while poking around.

You tell the SmartShunt what it is measuring using Victron connect, choose from things like DC system, wind power, fuel cell etc. etc. In your case it should be DC System if it is to the RV DC loads. The GX also needs the "Has DC System" enabled on the System Setup page.
