Victron Energy® SBS050150200 - Smart Battery Sense

Improves battery charging
By measuring voltage at the battery bank terminals, errors arising from voltage-loss due to cable resistance are avoided - guaranteeing the correct charge-voltage.

For lead batteries, battery temperature data is used to adjust the charge-voltages: cold batteries require an increased charge-voltage, whereas hot batteries require a decreased charge-voltage. For lithium batteries temperature data is used to disable charging when they are too cold: charging lithium batteries near or below freezing causes permanent damage to the cells.

Look no wires
The connection between Smart Battery Sense and one or more Solar Charger(s) is wireless: It uses VE.Smart Network - a wireless technology based on Bluetooth Smart.

Information transmitted can be used simultaneously by one, two or more Solar Chargers connected to the same 12V, 24V and 48V battery bank. The Smart Network is set up using the VictronConnect app.

Tidy, simple - smart
Installation is simple, quick and tidy. Just connect the unit's two eyelets to your battery terminals and attach the Smart Battery Sense unit directly onto the battery-body using its self-adhesive strip.

The VE.Bus Smart dongle is a Bluetooth Smart enabled VE.Bus interface, with battery temperature-and-voltage sensing. It communicates system information straight to your smart phone - using the free-to-use VictronConnect app. When used with Multi- inverter/chargers the dongle provides on-battery temperature and voltage sensing capabilities - allowing compensation for possible cable losses which can occur during charging and discharging. Temperature sensing allows accurate temperature-compensation during battery charge cycles. The dongle is, at present, the only way to add an “on-battery" sensing capability to the MultiPlus-II models, if they are not also connected to a GX device and CANbus battery.
The dongle can be used in systems with or without a GX device - such as the CCGX. In systems with a GX device, and another source of temperature and voltage data (eg from a CANbus battery), the CCGX data will override temperature and voltage information from the dongle. In this role the dongle will still provide live-information via its VictronConnect interface; and it will provide firmware updates without requiring an internet connection.
When the dongle is used in systems which do not have a GX device, the dongle's voltage and temperature data becomes the primary source of that information, and can be used by other connected devices for voltage compensation. In systems with a Multiplus-II, dongle and GX device, but no other source of temperature and voltage, the data from the dongle will also be used.
At this time, the VE.Bus Smart dongle cannot send its temperature and voltage data as part of a VE.Smart network.
The VE.Bus Smart dongle is able to sense battery temperature in two ways: The default method is the dongle's on-board temperature sensor. When the dongle is mounted directly onto the battery case (using its adhesive attachment) it will sense the battery temperature directly from the battery casing. The 2nd method - which provides improved battery temperature sensing - is available by using an optional battery-terminal mounted sensor. When this sensor is connected, the default sensor is overridden and the dongle will use this method instead.
