Victron Energy SmartShunt 500 amp Battery Monitor (Bluetooth)

Product Information

To understand which size inverter you require, you will need to work out the wattage to match your requirements. To do this, you will need to add up the wattage of each 230V appliance you want to use, and find out their rated power draw. Usually the item manual will provide the wattage draw.

Alternatively, the SmartShunt can be connected and be read by a GX device. Connection to the SmartShunt is made via a VE.Direct cable. The Victron manual states: The “charged voltage” parameter should be set to 0.2V or 0.3V below the float voltage of the charger. Hydrocephalus shunt technology: 20 years of experience from the cambridge shunt evaluation laboratory. J Neurosurg. 2014; 120( 3):697–707. [ PubMed] [ Google Scholar] When the current measured falls below the “Current threshold” value it will be considered zero. The “Current threshold” is used to cancel out very small currents that can negatively affect the long-term state of charge readout in noisy environments. For example, if the actual long-term current is 0.0A and, due to injected noise or small offsets, the battery monitor measures 0.05A the batery monitor might, in the long term, incorrectly indicate that the battery is empty or will need to be recharged. When the current threshold in this example is set to 0.1A, the battery monitor calculates with 0.0A so that errors are eliminated. If you have a laptop which is 60W, a TV which is 51W, and a coffee machine which is 1400W, then your maximum power usage would be 1511W.

[ 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.

Victron does not yet have the Bluetooth thing figured out yet, a shame. If 4 meters (~12ft) is the best they will go like @Lawrence Craig mentioned, Victron still has a lot to develop to get a solid Bluetooth product. 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. 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.
