DESCRIPTION
Our Wall mount battery is composed of 102AH square cell prismatic cells,
certified to UL1973, UL1642, CSA UL9540A, IEC62133,
IEC62660, and equipped with an internal BMS offering all the electronic
protections (over-discharge current, over-charge current, cell monitoring,
automatic balancing, cold charge protection and many others).
The batteries are also equipped with a NADER UL1077 physical circuit breaker.
The complete battery assembly has been certified by Intertek and proof of ETL
SPE-1000 certification is on the battery.
The 24V batteries are composed of 8 cells in series.

TERMINALS
The batteries are equipped with M8 connectors.
CIRCUIT BREAKER
The batteries are equipped with a NADER physical circuit breaker, certified UL1077 and CSA C22.2 No. 235-04, of 200A (optional).
PARALLELING
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 w ill 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
Lithium Wall mount 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 27.5V .
- The 5 KW batteries will push a current parameter :
– of recharge at 50 AMP.
– of discharge at 100 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.
- Configure batteries with Growth USE settings. ( Not USE2)
Solar (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 Solar.
- Switch on the power supply of the Solar with the batteries.
- Please set the battery type so that the UPS can communicate with the BMS of the Lithium 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 Lithium technical service. The RS485-USB cable will be necessary.
- Connect the batteries together via the Battery-comma 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)
- 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 Venuses’ device with a VE.CAN RJ-45 cable to the BMSCAN port of the Venuses’ device from Victron. -
If your Venuses’ 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 Venuses’ 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

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.
