Hello all, first post here.
A couple of days ago I installed a SmartShunt 500/50 and a 75/15 Smart MPPT controller in a motorhome. When everything is off and nothing can be used the shunt is showing current draw of 0.10A to 0.20A.
According to the datasheets, the MPPT has self consumption of 10mA, and the SmartShunt is <1mA. 11mA combined for the two. However, I'm drawing 10 to 20x more. The accuracy of the shunt is ±0.1A, so shouldn't it be reading 0.1A as a maximum? I appreciate this is a minor amount... I'm just curious as to why the numbers are 10 to 20 times out.
A couple other question while I'm here:
Is there any value in creating a VE network and joining both devices?
For the shunt, I only updated the battery Ah. Did I need to do anything with other settings and options (Sync SOC, zero current calibration, charged voltage etc)?
I didn't really know anything about solar and electrics before this, so it's been a steep learning curve! Many thanks in advance.
