| Use VE.Smart to add remote voltage, temperature and/or current sensing to your Victron MPPT Solar Chargers. Connect either a BMV battery monitor - or the new [[https://www.victronenergy.com/accessories/smart-battery-sense|Smart Battery Sense]], to a Solar Charger. The Solar Charger will receive the available information from the battery , like battery voltage and temperature (depending on the sensor) information, and use that data to optimize its charge parameters. This will improve charging-efficiency and prolong battery life. | Use VE.Smart to add remote voltage, temperature and/or current sensing to your Victron MPPT Solar Chargers.

| Use also now the VE.Smart Networking to synchronise the charger algorithms from Solar Chargers and improve even further the charge-efficiency and battery life. This feature is only available on SmartSolars with firmware version equal or higher then v1.47 (Ve.Direct SmartSolars) and v1.04 (Ve.Can SmartSolars). | Pairing two or more SmartSolar chargers in a VE.Smart Network, enables synchronised charging. This improves the charge efficiency and battery life. |

| For lithium batteries the charge-voltages remain the same at all temperatures, as long as it’s not //too// cold. Its better to not charge Ltihium batteries below 5C, to prevent them from being damaged and degraded. | For lithium batteries the charge-voltages remain the same at all temperatures, as long as it’s not //too// cold.

| The battery current is used to allow the tail current setting (see the [[victronconnect:mppt-solarchargers#battery_settings|Solar Charger Manual]] for more details) to be used more precisely as, by having the actual battery current, the Solar Charger can decide better if absorption phase should stop and go to equalisation/float phase. | The battery current data is used to allow the tail current setting (see the [[victronconnect:mppt-solarchargers#battery_settings|Solar Charger Manual]] for more details) to be used more precisely as, by having the actual battery current, the Solar Charger can decide better if absorption phase should stop and go to equalisation/float phase. |

In systems which have a [[venus-os:start|GX device]], do not use VE.Smart Networking - [[https://www.victronenergy.com/live/victronconnect:ve-smart-networking#faq|See FAQ 6.]] If for some reason, the same information is being received by the charger over BLE and VE.Can/VE.Direct, the information coming over BLE (through VE.Smart Networking) will be ignored. | * VE.Smart Networking is designed for small systems which do not have a [[venus-os:start|GX device]] - such as a Color Control GX or Venus GX - controlling the chargers (e.g. in an ESS system) - [[https://www.victronenergy.com/live/victronconnect:ve-smart-networking#faq|See FAQ Q5]]. In systems which the [[venus-os:start|GX device]] is used for logging purposes only, VE.Smart Networking can be used to allow chargers to synchronise, or even receive information from sensors. Keep in mind that if, for some reason, the same information (i.e. voltage sense) is being received by the charger over BLE and VE.Can/VE.Direct, the information coming over BLE (through VE.Smart Networking) will be ignored. |

| * It is not possible to measure multiple battery temperatures/voltages/charge currents: only one Smart Battery Sense, or one BMV can be used in a system. Having multiple sensors connected to different batteries can lead to charging issues as overcharging or heating up the batteries. Always make sure to have your sensors/chargers on the VE.Smart Networking connected to the same battery. If, by accident, two or more sensors (e.g. Smart Battery Sense and/or BMV) are connected to the same VE.Smart Networking, a priority mechanism is used to decide which battery temperature, battery voltage and battery current should be used by the charger. The priority mechanism is first based on the type of sensor (e.g. BMV has higher priority than the Smart Battery Sense), and second based on the serial number of the sensor. At the end, only one information will be used by the charger. | * It is not possible to measure multiple battery temperatures/voltages/charge currents: only one Smart Battery Sense, or one BMV can be used in a system.

| |
| No. The GX device already has voltage sensing (soon they will have temperature sensing too). Adding Smart Battery Sense to the installation will confuse the voltage-sensing data. For further information please see: [[https://www.victronenergy.com/live/ccgx:start#dvcc_-_distributed_voltage_and_current_control|CCGX/Distributed Voltage and Current Control.]] | Yes, but keep in mind that if, voltage or temperature information is also present on the GX Device, the charger will use that information in favor of the information coming from the Smart Battery Sense. The GX device already has, in most cases, voltage sensing (soon they will have temperature sensing too), so adding a Smart Battery Sense to the installation is not necessary.
