I have a Victron off-grid setup in my Amarok which is working great except for being able to monitor alternator charge and therefore battery charge percentage while the engine is running. When alternator is not on, the DC load through the smart shunt is displayed as a negative which in turn reduces the battery charge % displayed as it should. However when the alternator kicks in and the dcdc charger is working, instead of the load turning into a positive and increasing the battery charge%, it is displayed as an increased negative (not sure if it's cumulative or then difference) and reduces what is displayed as the percentage charge % of the batteries by that amount when we know the batteries are being charged. SmartShunt battery monitor and "Have DC system" are both selected on the Cerbo GX.
Setup summary
2 X 100ah LiPro lithium batteries
Victron Multiplus 12/2000
Cerbo GX with touchscreen
Victron SmartSolar 100/30
Smart Shunt
Amarok smart alternator
Redarc BCDC 40 dcdc charger
House batteries earthed through to main vehicle battery earth
All DC load and DCDC charger connected to load side of shunt
Only the two house batteries are connected to input side of shunt
SmartSolar and Multiplus hard wired to CerboGX
Any guidance would be appreciated.
