Supply voltage (V+ supply): 9V-70V
Maximum supply current: 500mA
Data rate: 250 kbps
CANH/CANL voltage tolerance: +/-70VDC
CAN transceiver ISO specification: ISO 11898-2:2016
To provide maximum flexibility, the battery voltage is used for the V+ supply line of VE.CAN. This means that all
equipment connected to VE.CAN are a permanent load to the battery.
3.7. Synchronised parallel operation
Several charge controllers can be synchronised with the CAN interface. This is achieved by simply interconnecting the chargers
with RJ45 UTP cables (bus terminators needed, see section 3.6).
The paralleled charge controllers must have identical settings (e.g. charge algorithm). The CAN communication ensures that the
controllers will switch simultaneously from one charge state to another (from bulk charge to absorption for example). Each unit
will regulate its own output current, depending on the output of each PV array and cable resistance.
In case of synchronized parallel operation, the network icon will blink every 3 seconds on all paralleled units.
The PV inputs should not be connected in parallel. Each charge controller must be connected to its own PV array.
3.8. Energy Storage System (ESS)
An Energy Storage System (ESS) is a specific type of power system that integrates a power grid connection with a Victron
Inverter/Charger,
GX device
and battery system. It stores solar energy into your battery during the day, for use later on when the
sun stops shining.
Please refer to the following manual how to setup an ESS:

3.9. User I/O
3.9.1. Remote on/off connector
The remote on/off connector has two terminals, the "Remote L" and the "Remote H" terminal.
The ships with the remote on/off connector terminals connected to each other via a wire link.
Note that for the remote connector to be operational, the main on/off switch on the needs to be switched to "on"
The remote on/off connector has two different operational modes:
On/off mode (default):
The default function of the remote on/off connector is to remotely switch the unit on or off.
• The unit will switch on if "Remote L" and the "Remote H" are connected to each other (via a remote switch, relay or the wire
link).
• The unit will switch off if "Remote L" and the "Remote H" are not connected to each other and are free floating.
• The unit will switch on if "Remote H" is connected to battery positive (Vcc).
• The unit will switch on if "Remote L" is connected to battery negative (GND).
2-wire BMS mode:
This feature can be enabled via VictronConnect. Go to "battery settings" and then to "Remote mode". (see attached image)
Set the remote mode from "on/off" to "2-wire BMS".
In this mode, the "load", "load disconnect" or "allowed to discharge" signal and the "charger", "charger disconnect" or "allowed
to charge" signals from a Victron lithium battery BMS are used to control the unit. They respectively turn the inverter off in case
discharge is not allowed, and turn the solar charger off if charging is not allowed by the battery.
• Connect the BMS "load", "load disconnect" or "allowed to discharge" terminal to the Inverter RS Smart "Remote H" terminal.
• Connect the BMS "charger", "charge disconnect" or "allowed to charge" to the unit Inverter RS Smart "Remote L" terminal.
