TERMINALS
The 10 kWh batteries are equipped with M8 connectors (two positive, two
negative).
The 5 kWh batteries are equipped with Surlok connectors compatible with a
gauge from AWG-2 to AWG-2/0.
These are Amphenol brand. The models of terminals attached to the battery
(“Receptacle”) are “SLPPB35BNO” for the positive and “SLPPB35BNB” for the
negative. They are compatible only with a PLUG type terminal of Amphenol
Surlok brand.
Here is an example of a compatible connector (black): “SLPPB35BNB”.
Here is an example of a compatible connector (positive): “SLPPB35BNB”.
See the last page of this document for full details and model number
nomenclature for Surlok. Official connectors are available from DigiKey,
Newark and Mouser. The Surlok receptacles used on the battery are UL1977
certified.
CIRCUIT BREAKER
The batteries are equipped with a NADER physical circuit breaker, certified
UL1077 and CSA C22.2 No. 235-04, of 125A. (150A for
10 seconds).
PARALLELING
When the continuous current of the battery bank exceeds 150A, we suggest the
use of a bus bar. Each battery will connect to the bus bar with an AWG-2
cable, and then from the bus bar to your equipment with the cable of your
choice.
The batteries can be connected in parallel even if they are not at the same
charge level.
Indeed, the batteries are equipped with an incoming charge regulator. That
said, if you send the battery a charge current higher than the limit
programmed in the BMS (e.g. 154A), the battery will activate its regulator,
and the maximum incoming current will be 9 amps. Thus, if a full battery is
connected to the empty battery, the latter will automatically activate its
integrated regulator. Note that the BMS will deactivate the regulator after 3
minutes, and reactivate it automatically if necessary.
ID ADDRESS PER BATTERY
It is important to define a different address for each battery using the Dip
Switches. Each battery has 4 small switches.
Depending on the protocol used, the address assignment may vary. Refer to the
diagram below.
COMMUNICATION
Volthium RACK batteries integrate RS485 and CANBUS communication protocols. Through the communication, the batteries will push the charging parameters. The installer can manually enter the charging parameters of the devices, or configure the devices so that the battery pushes the parameters. The parameters that the battery pushes are conservative and are intended to promote maximum battery life.
-
The (default) battery software will push a bulk of 55.0V and a float of 54V.
-
The 5 KW batteries will push a current parameter :
– of recharge at 50 AMP.
– of discharge at 100 AMP. -
The 10 KW batteries will push a current parameter :
– of recharging at 90 AMP.
– of discharge at 150 AMP.
SETTING UP COMMUNICATION TO POPULAR INVERTERS
GROWATT (in RS485)
Connect the batteries together via the RS485 ports only. Each battery has two
RS485 ports, allowing easy interconnection from one battery to another.
- Set the first (master) battery to ID #2, and the following ones in order (3-4-5-6…).
- No battery has the #1 position, that’s normal!
- Connect the battery with ID #2 from its RS485 port to the UPS with a standard network cable.
- As Volthium batteries have an internal BMS, you should use the GroWatt USE setting.
(The USE2 setting in the Growatt is for lithium batteries that do not have internal BMS)
Solark (in CAN)
Connect the batteries to each other via the Battery-Comm ports only. Each
battery has two “Battery-Comm” ports, allowing easy interconnection from one
battery to another.
- Set the first battery (master) to ID #1, and the following ones in order (3-4-5-6…).
- Please make sure you have not used the ID #2 address.
- Connect the battery with ID #1 from its CAN port to the inverter with a standard network cable, to the CAN port of the Solark.
- Switch on the power supply of the Solark with the batteries.
- Please set the battery type so that the UPS can communicate with the BMS of the Volthium battery.
- Wait for 3 minutes and the BMS values will be available on the inverter display.
SCHNEIDER (IN RS485)
-
Update the battery with the Schneider firmware available from Volthium technical service. The RS485-USB cable will be necessary.
-
Connect the batteries together via the Battery Comm ports only. Each battery has two Battery Comm ports, allowing easy interconnection from one battery to another.
-
Set the first (master) battery to ID #1, and the following ones in order (2-3-4-5-…).
-
Plug a standard network cable into the RS485 port of the battery with ID #1, and cut the other end of the RJ45 cable to strip the white-brown and brown strands (7 and 8).
-
Connect the white-brown wire to the RS485-A connector of the Schneider HomeInsight (PIN 9 on the HomeInsight)
Note: the BMS cannot be connected directly to the Xanbus communication ports. -
Connect the brown wire to the RS485-B connector of the Schneider HomeInsight (PIN 11 on the HomeInsight)
-
In Schneider’s online portal, in the green horizontal menu, go to “Setup”, then in the left vertical menu, click on “Configuration”, then in the on-screen page, click on “Modbus Setting”, and set the port speed of “Serial PORT A” to 19,200 baud.
-
Still in the Schneider online portal, go to “Setup” in the horizontal menu, press “Device Detection”, then enter the “Range” of addresses you have. If you have only one battery, put from 1 to 2 as in the example:
- Press “Close”. That’s it, the battery will appear in your “Devices”.
CONNECTION TO VICTRON
-
Connect the batteries to each other via the Battery-Comm ports only using standard network cables. Each battery has two “Battery-Comm” ports, allowing easy interconnection from one battery to another.
– Set the first battery (master) to ID#1, and the following ones in order (3-4-5-6…).
– Please make sure that you do not use the ID #2 address.
– Connect the battery with ID #1 from its CAN port to the VenusOS device with a VE.CAN RJ-45 cable to the BMSCAN port of the VenusOS device from Victron. -
If your VenusOS device does not have a BMS-CAN port, you can use the VE.CAN port as long as you set the port’s baud rate in the VenusOS settings (500 kb/s BMS-CAN).
-
To do this, navigate to the Venus operating system and go to “Settings” “Services”. Can-Profile.
- Finally, use a Victron termination connector to close the communication loop. Note that you cannot close the loop on the battery with this termination adapter.
Make your own cable (VE.CAN). Here is the Pin-Out
Description|

VE.Can : Victron equipment| B-green, Green. Orange, B-Brown, B-Orange, Brown,
Blue, Bblue
RS-485 AND SIMULTANEOUS CAN
If you want to use RS-485 communication with a computer in addition to the
connection to Victron, then each of the batteries will be connected with 2
straight network cables. The addressing will remain the same. Understand that
the RS-485 link is independent of the CAN link.

OPERATION OF THE SELF-HEATING FUNCTION
Batteries with a self-heating system will activate when an external load is
sent to the system and the internal temperature of the battery is below zero.
Thus, when the battery is connected to a charger or any other energy source
(solar, generator, wind or other), the BMS will first use the incoming current
to build up an internal heat of 11ºC and then start charging the battery. The
power source must be at least 6A for 5Kw batteries and 8A for 10Kw batteries,
for the self-heating system to start. The system will be able to make the
battery go from -20ºC to 11ºC in only 2 hours.
The battery never uses its own energy to run the heating system.
