VE.Bus BMS
EN
1. General Description
NL
Protects each individual cell of a Victron lithium iron phosphate (LiFePO₄) battery
Each individual cell of a LiFePO₄ battery must be protected against over voltage, under voltage and over temperature.
Victron LiFePO₄ batteries have integrated Balancing, Temperature and Voltage control (acronym: BTV) and connect to the
VE.Bus BMS with two M8 circular connector cord sets.
The BTV’s of several batteries can be daisy chained. Please see our LiFePO4 battery documentation for details
The BMS will:
shut down or disconnect loads in case of imminent cell under voltage,
reduce charge current in case of imminent cell overvoltage or over temperature (VE.Bus products, see below), and
shut down or disconnect battery chargers in case of imminent cell overvoltage or over temperature.
FR
DE
Protects 12 V, 24 V and 48 V systems
Operating voltage range of the BMS: 9 to 70 V DC.
Communicates with all VE.Bus products
The VE.Bus BMS connects to a MultiPlus, Quattro or Phoenix inverter with a standard RJ45 UTP cable.
Products without VE.Bus can be controlled as shown below:
ES
Appendix
Load Disconnect
The Load Disconnect output is normally high and becomes free floating in case of imminent cell under voltage. Maximum
current: 2 A.
The Load Disconnect output can be used to control
the remote on/off of a load, and/or
the remote on/off of an electronic load switch (BatteryProtect, preferred low power consumption solution) and/or
a Cyrix-Li-load relay.
Charge Disconnect
The Charge Disconnect output is normally high and becomes free floating in case of imminent cell over voltage or over
temperature. Maximum current: 10 mA.
The Charge Disconnect output can be used to control
the remote on/off of a charger and/or
a Cyrix-Li-Charge relay and/or
a Cyrix-Li-ct Battery Combiner.
LED indicators
Enabled (blue): VE.Bus products are enabled.
Cell>4V or temperature (red): charge disconnect output low because of imminent cell over voltage or over
temperature.
Cell>2,8V (blue): load disconnect output high.
Load disconnect output low when off, due to imminent cell under voltage (Vcell≤2,8V).
2. Safety instructions
Installation must strictly follow the national safety regulations in compliance with the enclosure, installation, creepage, clearance,
casualty, markings, and segregation requirements of the end-use application. Installation must be performed by qualified and
trained installers only. Switch off the system and check for hazardous voltages before altering any connection.
• Do not open the Lithium Ion Battery.
• Do not discharge a new Lithium Ion Battery before it has been fully charged first.
• Charge only within the specified limits.
• Do not mount the Lithium Ion Battery upside down or on the side.
• Check if the Li-Ion battery has been damaged during transport.
3. Things to consider
3.1 Important warning
Li-ion batteries are expensive and can be irreparably damaged due to over discharge or over charge.
Damage due to over discharge can occur if small loads (such as: alarm systems, relays, standby current of certain loads, back
current drain of battery chargers or charge regulators) slowly discharge the battery when the system is not in use.
In case of any doubt about possible residual current draw, isolate the battery by opening the battery switch, pulling the battery
fuse(s) or disconnecting the battery plus when the system is not in use.
A residual discharge current is especially dangerous if the system has been discharged completely and a low cell
voltage shutdown has occurred. After shutdown due to low cell voltage, a capacity reserve of approximately 1 Ah per
100 Ah battery capacity is left in the battery. The battery will be damaged if the remaining capacity reserve is drawn
from the battery. A residual current of 10 mA for example may damage a 200 Ah battery if the system is left in
discharged state during more than 8 days.

4. Installation
Note 1: The AC Detector is not needed in case of an inverter.
Note 2: In systems consisting of several units configured for parallel, three phase or split phase operation, The AC Detector should be wired in the
master or leader unit only.
Note 3: The VE.Bus BMS assistant or the Self-consumption Hub-2 v2 assistant must be loaded in all units.
NL
4.1 AC Detector for MultiPlus and Quattro (included in VE.Bus BMS delivery)
The purpose of the AC Detector is to restart the MultiPlus or Quattro when AC supply becomes available, in case it has been
switched off by the BMS due to low cell voltage (so that it can recharge the battery).

5.
Use the short RJ45 UTP cable to connect the AC Detector to one of the two the VE.Bus sockets in the MultiPlus or
Quattro (see figure 4).
Connect the VE.Bus BMS to the AC Detector with a UTP cable (not included).
Any control panel, such as the Color Control or the Digital Multi Control panel must be connected to the VE.Bus BMS.
Do not connect a control panel directly to a Multi or Quattro (signals from the control panel may be in conflict with
signals from the VE.Bus BMS).
Figure 4: VE.Bus connections
4.2 Wire the system: see system examples below
Do not connect to the battery plus at this stage (alternatively: do not insert the battery fuse(s)).
Important:
1. The UTP cable to the inverter or inverter/charger also connects the battery minus to the BMS.
In this case, in order to prevent ground loops, do not wire the battery minus connector of the BMS.
2. Wire the positive supply input of the VE.Bus BMS to the system positive. A system on-off switch in the positive supply
wire will disable the system when opened.

4.2. Battery
In case of several batteries in parallel and or series configuration, the two M8 circular connector cord sets of each battery should
be connected in series (daisy chained).
Connect the two remaining cord sets to the BMS.
EN
4.3. Powering up
In case of a DC only system: connect the battery plus. The system is now ready for use.
NL
FR
In case of a system with Multis, Quattros or inverters with VE.Bus:
4.3.1. After completion of the installation, disconnect the BMS from the VE.Bus and replace by a Victron Interface MK2 and a
computer.
4.3.2. Connect the battery plus.
4.3.2. Configure inverter/charger(s) or inverter(s) for parallel or three phase configuration if applicable.
Inverter/chargers: the AC Detector should be installed only in the master or leader of a parallel or three phase system.
Inverters: AC detector not needed.
4.3.3. Load the BMS VE.Bus assistant in all units (must be done for each unit separately)
4.3.4. Remove the MK2 and reconnect to the BMS.
4.3.5. The system is now ready for use

7. Frequently asked questions
Q1: I have disconnected the VE.Bus BMS, and now my Multi or Quattro will not switch on, why?
A Multi or Quattro programmed with the VE.Bus BMS assistant, and unable to find a VE.Bus BMS on the bus, will go into an
emergency mode. In this mode it will charge the batteries with 5 Ampère max, up to 12 V, 24 Vor 48 V, depending on system
voltage. Note that in this mode, the only LED which is on is the Mains On LED. If you disconnect the AC input from the
Multi/Quattro, it will switch off. It will not start to invert since it cannot get verification on the battery health from the VE.Bus BMS.
Note that, when the batteries are depleted or disconnected, Quattro’s need to be powered from AC input 1. Supplying power to
AC Input 2 will not make a Quattro switch on and start charging.
Q2: The batteries are empty, and the Multi/Quattro will not start to charge, how to get the system up and running again.
When lithium batteries are depleted (the voltage is around 9 V or even lower) the battery voltage might be below the operating
window of the VE.Bus BMS. In that case the VE.Bus BMS will not be able to start the Multi/Quattro, even if an AC Detector is
installed. To start the system again, disconnect the VE.Bus BMS from the Multi, and refer to Q1. Note that it might be necessary
to disconnect any Blue Power Panels, NMEA2000 interfaces or other similar smart products. As long as they are not switched
on themselves, they can prevent the Multi/Quattro from starting up.
A simpler option to revive a depleted system might be to connect a small battery charger, for example 5 Ampère, and wait for
the battery voltage to get back up to 12 Volt.
Q3: What happens with the Multi/Quattro when the BMS gives a low cell voltage signal?
The Multi/Quattro will be in charger only mode: when AC input is present, it will charge the batteries. And when the AC input is
not present, it will switch off
Q4: What happens with the Multi/Quattro when the BMS gives a high cell voltage signal?
The high cell voltage signal will only be given when there are unbalanced cells. The Multi/Quattro will switch to bulk, and starts
charging with a reduced charge current. This allows the balancing system to rebalance the cells.
