By connect I mean I can launch VictronConnect and see from the Device List the basic live reporting information sent from the shunt. So far so good. It's doing what I hoped it would do.

[ PubMed] The Victron manual states: The “charged voltage” parameter should be set to 0.2V or 0.3V below the float voltage of the charger. The SmartShunt is a good alternative for a BMV battery monitor, especially for systems where battery monitoring is needed but less wiring and clutter is wanted. The SmartShunt is equipped with Bluetooth, a VE.Direct port and a connection that can be used for: monitoring a second battery, midpoint monitoring or a temperature sensor. When connecting with the VictronConnect app, while an alarm is active, the alarm will show in the app. Alternatively, when the battery monitor is connected to a GX device, the alarm will show on the GX device display or the VRM portal.

Calculating how many solar panels to install should be one of your first considerations.

The main function of the battery monitor is to follow and indicate the state of charge of a battery, to be able to know how much charge the battery contains and to prevent an unexpected total discharge.

Remark: Some battery chargers stop charging when the current drops below a set threshold. In these cases, the tail current must be set higher than this threshold. The battery monitor continuously measures the current flow in and out of the battery. Integration of this current over time, if it was a fixed current, boils down to multiplying current and time and gives the net amount of Ah added or removed. The SmartShunt is a powerful battery monitor with Bluetooth on board. It can be installed out of sight, behind the scenes – whilst live data from the device is relayed to your mobile phone or laptop via the VictronConnect App, which is free to use. Displays: Voltage/ Current / Power / Ah Consumed / State of Charge (%) / Time-to-go / Total kWh charged/discharged Set the Peukert exponent according the battery specification sheet. If the Peukert exponent is unknown, set it at 1.25 for lead-acid batteries and set it at 1.05 for lithium batteries. A value of 1.00 disables the Peukert compensation. The Peukert value for lead- acid batteries can be calculated. Charge efficiency factor (%)Working principle of a variable pressure valve. An external magnetic tool is used to rotate and adjust the valve. The orientation of the valve is measured by an external indicator. The battery monitor estimates how long the battery can support the present load. This is the “time-to-go” readout and is the actual time left until the battery is discharged to the set “discharge floor”. The discharge floor is by default set at 50%. For the discharge floor setting see the Discharge floor chapter. If the load is fluctuating heavily, it is best not to rely on this reading too much, as it is a momentary readout and should be used as a guideline only. We recommend the use of the state of charge readout for accurate battery monitoring. We hope that this document has been helpful for you.

If the “Time remaining” indicates three dashes: “---” this means that the battery monitor is in an unsynchronised state. This occurs when the battery monitor has just been installed or after it has been left unpowered and is powered up again. For more information, see see the Synchronising the battery monitor chapter.The auxiliary input can be used to monitor the voltage of a second battery or the midpoint of a battery bank. The auxiliary input can also be used for battery temperature monitoring, together with the optional Temperature sensor for BMV.

[ PMC free article] [ PubMed] [ Google Scholar] This is the actual current flowing in or out of the battery. A negative current indicates that current is taken from the battery. This is the current needed for DC loads. A positive current means that current is going into the battery. This is current coming from charge sources. Keep in mind that the battery monitor will always indicate the total battery current, being the current traveling into the battery minus the current traveling out of the battery.
