The shunt should be set to DC system iirc, not generic load.
If “DC meter” is selected, you can select the following types:
Solar charger, Wind charger, Shaft generator, Alternator, Fuel cell, Water generator, DC-DC charger, AC charger, Generic source, Generic load, Electric drive, Fridge, Water pump, Bilge pump, DC system, Inverter, Water heater.
When connected to a GX device, the type, the current and the power is shown in the user interface, and this information is also available on the VRM Portal.
When the GX device is also configured as type “has DC System”, the GX does more than just recording and visualisation:
- The power shown in the DC system box is the sum of power reported by all battery monitors configured as such. Having multiple meters can be useful, for example, in a catamaran, so that the DC systems in the port hull and in the starboard hull are being measured.
- The DC system current is being compensated for when setting DVCC charge current limits to inverter/chargers and solar chargers. For example, when a load of 50A is being measured, and CCL by the battery is 25A, the limit given to the inverter/charger or solar charger is 75A.
