Victron VE.Smart Networking: Wireless Sync & Setup

Key Takeaways

• The system operates where VE.Smart Networking is a wireless communication network between Victron products called Bluetooth Smart.
• Maintains a stable wireless mesh with The maximum number of devices that can be connected to one network is 10.
• Facilitates unified solar charging: Connect multiple SmartSolar charge controllers together in a VE.Smart network to make them charge the battery as if they were one large charger.
• Ensures coordinated charge state transitions: They will simultaneously switch from one charge state to another, for example from bulk to absorption.
• Provides accurate remote voltage telemetry: Remote Voltage reading - Vsense.
• Broadcasts battery temperature for thermal compensation: Temperature sensing - Tsense.
• Enables precision tail-current charge termination: Current sensing - Isense.
• Coordinates unified charging logic through Synchronised charging.
• Optimized for compact off-grid applications: VE.Smart Networking is designed for small systems that do not have a GX device.
• Incorporates clear hierarchy rules: 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.
• Improves battery performance and longevity: These chargers use the battery's available information to optimise charging parameters.

Wireless Mesh Architecture & Shared Sensor Telemetry

VE.Smart Networking eliminates the need for physical data wiring or expensive GX central hubs in compact mobile, marine, and off-grid installations. By utilizing low-power Bluetooth Smart broadcasts, sensing devices transmit live battery data directly to charging devices.

The VE.Smart Networking mesh operates as a Bluetooth Smart wireless network connecting up to 10 devices, designed for autonomous systems without a central GX controller:

• Transmitters (Sensors): Smart Battery Sense, SmartShunt Monitor, BMV-712 Smart, Vsense, Tsense, Isense.
• Receivers (Chargers): SmartSolar MPPTs, Orion XS DC-DC, Smart IP43 Units, Auto Parameter.
• Wireless Sync: Multi-MPPT, Simultaneous, Bulk-to-Abs, Wired Priority.

Sensor Broadcasting & Charge Optimization

1. Voltage Sensing (Vsense): Transmitting Remote Voltage reading - Vsense allows chargers to compensate for cable voltage drops between controller terminals and battery posts.
2. Temperature Sensing (Tsense): Transmitting Temperature sensing - Tsense enables temperature-compensated lead-acid charging or prevents lithium charging below freezing.
3. Current Sensing (Isense): Transmitting Current sensing - Isense from a SmartShunt allows MPPTs to terminate the absorption cycle when battery tail current falls below threshold.
4. Overall Optimization: Through these telemetry streams, These chargers use the battery's available information to optimise charging parameters.

Synchronized Multi-Charger Operation & Priority Rules

In setups with multiple solar arrays or combined DC-DC and solar chargers, VE.Smart Networking coordinates the entire charging group:

• Synchronized Charging: When you Connect multiple SmartSolar charge controllers together in a VE.Smart network to make them charge the battery as if they were one large charger, individual controllers pool their charging phases through Synchronised charging.
• State Switching: Controllers maintain uniform charging algorithms: They will simultaneously switch from one charge state to another, for example from bulk to absorption, preventing one controller from prematurely entering float while another is in bulk.
• Network Capacity: Up to 10 nodes can communicate simultaneously: The maximum number of devices that can be connected to one network is 10.
• Target Scope: Ideal for modular compact setups: VE.Smart Networking is designed for small systems that do not have a GX device.
• Wired Hierarchy: If a GX device is subsequently added, **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**.
