I have seen that the multiplus displays a current of - 0,4 A but the batterie state inactiv is displayed .
So now in winter the SOC of the batterie is lower and lower even no real current is flowing .
Also I have the display ESS #1 SOC is low and ESS #2 batterie life is activ.
Is there a reason for this ? Ore need the smart shunt to calibrated to zero ?
