BMV SmartShunt Current Alarm Setup

Having an alarm state issue. In VRM I have a current alarm setup as follows on my SmartShunt Low = 0, Low Clear = 0, High = 140 and High Clear= 130. I constantly get an alarm state for low current during the day when solar is outpacing load. It never clear. Is there a better way to set this up?

Goal of the alarm is to make sure I don’t pull too much from batteries when running my Air Conditioner on RV.

Equipment:

- Cerbo GX

- Smart Shunt

- 100/50 MPPT

- MultiPlus II 2x120v

Hi, As your amps will go negative when there is no sun or low sun and the air con is on then you would be alarming all the time with those settings ie it flows from charging at 30 amps down to zero to then down more to say negative 20 amps than back to positive as clouds etc move over and away from the panels

suggest you look at using SOC or battery voltage to trigger the alarm
