BMV-712 Smart and SmartShunt — battery monitors
Country: Netherlands · Model: BMV-712 Smart / SmartShunt
The BMV-712 Smart and SmartShunt battery monitors measure current through a shunt, rated 300, 500, 1,000 or 2,000 A on the SmartShunt. The BMV comes with a 500 A/50 mV shunt. They fit any DC system with lead-acid or lithium batteries.

Description
The shunt goes in the negative battery lead, so all charge and load current passes through it. The monitor measures voltage and current and uses them to calculate state of charge (SoC) and remaining runtime. Midpoint monitoring shows imbalance between the two halves of a battery bank and catches a weak block in a series string early. Data goes to a smartphone over Bluetooth and to a system controller over VE.Direct. This shows how much energy is really left instead of just the terminal voltage, which on LiFePO4 barely moves until the bank is almost empty. The BMV-712 Smart has its own display for panel mounting, while the SmartShunt has none and is read from the app or a GX controller.
How to choose
The shunt rating should cover the highest continuous current of the system, inverter draw included. A small system with a panel display takes the BMV-712 Smart with its 500 A/50 mV shunt. For large inverters such as the MultiPlus at 5 kVA or the Quattro, the SmartShunt at 1,000 or 2,000 A matches the current. Where a Cerbo GX is installed, the SmartShunt feeds it over VE.Direct and the data reaches the VRM portal.

FAQ
What current ratings does the SmartShunt come in?
The SmartShunt is made for 300, 500, 1,000 and 2,000 A.
Which shunt comes with the BMV-712 Smart?
A 500 A/50 mV shunt.
What does the SmartShunt measure?
Voltage, current, SoC, remaining runtime and the bank midpoint.
Where is the SmartShunt connected?
In the negative lead between the battery and all loads and chargers, so every amp passes through the shunt.
Why is midpoint monitoring useful?
It compares the two halves of a series bank and shows imbalance before a weak block pulls the whole string down.
