SECTION 1: INSTALLATION
WARNING
This product may only be installed by a qualied electrical engineer. The unit
is not designed to be installed upside down or sideways on a wall.
The AM-2 is designed to be wall-mounted or installed at inside a cabinet. When installing on a
wall ensure you use Rawl boats to secure the unit to the wall.
DIP SWITCH SETTINGS
Congure each battery address to enable proper setup and communication. Each battery needs
a unique serial address in order to communicate. If you are only using one battery in your setup,
ensure you set the battery to Address 1.
Page 2
DC ISOLATOR
The Hubble AM series of batteries has an integrated electronic circuit breaker built into the BMS.
The integrated electronic CB is for protecting the battery and the internal cells against overload,
over current, over volt etc. It is however required to install an external DC fuse or circuit breaker
before using or operating the batteries. Please ensure you use the correct rating as per battery
specication.

MULTIPLE BATTERIES
To connect multiple batteries, ensure you use the supplied RJ45 to RJ45 (standard LAN cable) and
plug the one end into the master “Battery Link”, and the other end into battery #2. Continue this
step until all the batteries has been linked up
Continue to wire up the DC block terminals of each battery to the inverter/charger. Once you have
completed the address conguration, inverter-battery communication links and wired up the DC
connections you can proceed to congure the inverter charge settings.
NOTE: BATTERY LINK CABLE
If you do not have a battery link cable or the cable provided is an insuf-
cient length, you can use a standard computer LAN cable to connect each
battery. The pin layouts for the ports are the same as the universal LAN
cable.
WARNING: PROTECTION MODE
If your batteries are unbalanced or the voltage of each pack is different by more than 2 Volts DC
then your packs will try to inter balance by over 100Amps. This could cause the other batteries in
the conguration to Over Current and go into protection mode. If this occurs, charge each pack full
individually with the inverter/charger, then switch the other packs on once each has been charged
to 100%.

CORRECT METHODS OF BATTERY LINKING
Please note the below diagrams for the correct method of linking multiple batteries in parallel.
Diagram 1, displays a standard linking connection. Digram 2, displays parallel batteries to which
the negatives and positives are connected to common buzz bars.

COMMUNICATION PORTS
RS485 COMMUNICATION PORT
The RS485 interface is used only for performing rmware updates directly for the BMS. This port
cannot be used for any inverter communications.
PLEASE NOTE:
This port is reserved for administrative and workshop technicians.
RS232 COMMUNICATION PORT
The RS232 interface is used to connect to either the Hubble Cloudlink device or for technical sup-
port to interface directly through a service laptop and access the BMS directly for programming
and troubleshooting.
WARNING: FIRE HAZARD & WARRANTY VOID
DO NOT CONNECT THIRD PARTY DEVICE
It is strictly forbidden to access or interfere directly with the battery BMS through
third party devices such as monitoring devices or logging devices that are not
Hubble Lithium products.
Third party monitoring and interfacing devices have the potential to change
charge voltages and algorithms inadvertently - this can cause a catastroph-
ic re hazard. Therefore, interfacing to the BMS directly without authorization will
void the warranty and Hubble Lithium will not be liable for any resulting damages.

ABOUT THE CLOUDLINK DEVICE
The Hubble Cloudlink is an optional add-on to the Hubble X and AM range of products. As long
as the device is connected to Wi-Fi it will cloud, all battery and inverter data to our cloud-server,
enabling users to remotely monitor their power system.
Learn more about the Hubble Cloudlink here:

SECTION 2: INVERTER SETUP
PRE-LAUNCH INVERTER SETUP
Set your Inverter/charger to the corresponding settings below before you start charging or using
the lithium batteries.
VERY IMPORTANT NOTICE:
Set the voltages correctly as out
of range voltages can damage the
battery.
INVERTER/CHARGER SETTINGS
BULK / EQUALISATION CHARGE 53.6 V
FLOAT CHARGE 53.6 V
LOW DC CUTOFF 44 V
AXPERT RECOMMENDED SETTINGS
VOLTAGE POINT BACK TO UTILITY 47 V Axpert Type
VOLTAGE POINT BACK TO BATTERY 53 V Axpert Type
PLEASE NOTE: INVERTER SETUP GUIDES
If you are setting up a non-axpert type inverter, for example Deye or Sunsynk - please
navigate to the Inverter Setup Guides tab on our website and select the correct corre-
sponding inverter guide: https://www.hubblelithium.co.za/
The recommended cutoff is 44V ~ 45V. However, the internal battery cutoff is as low as 40V. Setting
the cutoff to 40V will drain the battery to 0%. For extended lifespan we recommend a cutoff of 44V
~ 45V.
CAN BUS SETUP (OPTIONAL)
The AM series models has an integrated CAN bus port on each battery. The CAN bus can be used
to connect to any inverter that is CAN bus ready.
To connect the CAN bus cable from the battery to the inverter, ensure you have the cor-
rect pin layouts. Firstly, ensure that you have the pin layout for the cable required
for your inverter. If you do not have this information, we list select inverter pin lay-
outs under the “Inverter Guides” tab on our website: https://www.hubblelithium.co.za/

When battery is turned on you
can reset the BMS operation
mode to default to clear a tem-
porary alarm status. Push the
switch for 6 seconds, the BMS
will reset. LEDs will ash one at
the same.

SECTION 4: BMS & MAINTENANCE
BMS LOW POWER MODE
The Hubble BMS will enter low power mode if the following conditions happen:
1. When over-discharge protection has occurred. (30S later).
2. When all cell-voltage is less than the Sleep voltage parameter setting to prevent complete
cell/ battery drain.
3. Standby time is more than 24 hours (without charge and discharge current, without balance,
without protection and fault).
BMS EMC SAFETY

Complies with Level 4 of GB/T 17626.2-2006 (EN55024): 8KV at contact and 15KV at air. Normal
operation after test.
ELECTROMAGNETIC CONDUCTION:
Complies with Lever A of YD/T 983-1998 (EN55022)
ELECTROMAGNETIC RADIATION:

INRUSH:
Complies with GB/T 17626.5-2008 (EN6100-4-2).
DATA STORAGE
The Hubble BMS has a built-in alarm and event data storage memory. Alarms and events are
recorded as, occurrence time, fault categories, over/under cell voltage, pack voltage, charge/dis-
charge capacity,charge/discharge current, temperature, etc. This can be downloaded by a service
technician to help troubleshoot any issues or problems of the battery.
MAINTENANCE
The Hubble BMS will protect the battery and lifespan of your battery as best possible. However, it
must be noted that proper operation of the battery is recommended, and maintenance functions
should be taken to ensure the maximum life of your batteries.
Cell balancing is a very important function of the lifespan of your battery. It is
important to ensure the cell balancing functions are properly performed. The
Hubble BMS cell balancer will only activate upon 100% state of charge when
the batteries near full charge. Thus, it is critical that a full charge to the batteries
are provided at least once every 5 (ve) days, but preferably daily upon a charge
cycle. Enough charge time should be provided to balance the cells until the BMS
completely stops taking charge from the inverter. Cell cycle life cannot be guaran-
teed if balancing is not performed on a regular basis. This is especially important
in complete off grid systems where a stable power supply is not available.
