BMV-712 high A and W numbers

Our customer has a problem with BMV-712 Smart

firmware v2.92

Voltage number OK for 48 V system

but the current and Wattage numbers are high like 1000 A

for shunt 500/50. We have advised to make the restart but

no changes.

Have you performed the zero current calibration?

Many thanks, it seems that there is something else wrong, in the VRM MV-712 Smart
firmware v2.92 VRM Portal ID c0619ab208cf
Voltage number OK for 48 V system
we can see the current MV-712 Smart
firmware v2.92 VRM Portal ID c0619ab208cf

the current 1014A and Wattage number 48000W
