Wire Diagram
The wiring diagram shows the various components of the AM-2 battery and inverter system, including the cover, hanging ear, handle, output terminal, cooling case, power switch, communication interface, reset switch, and LED lights.
Connecting Multiple Batteries
To connect multiple batteries, use the supplied RJ45 to RJ45 (standard LAN
cable) to connect the master Battery Link to battery #2. Continue this step
until all the batteries have been linked up. Wire up the DC block terminals of
each battery to the inverter/charger. Once you have completed the address
configuration, inverter-battery communication links, and wired up the DC
connections you can proceed to configure the inverter charge settings. Note
that if you do not have a battery link cable or the cable provided is an
insufficient 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. It is important to follow the correct methods of battery linking to
avoid issues with unbalanced batteries.
Communication Ports
The AM-2 battery and inverter system has two communication ports: RS485 and
RS232. The RS485 interface is used only for performing firmware updates
directly for the BMS. This port cannot be used for any inverter
communications.The RS232 interface is used to connect to either the Hubble
Cloudlink device or for technical support to interface directly through a
service laptop and access the BMS directly for programming and
troubleshooting. The RS232 pin layout includes
ground, BMS transmit, and BMS receive. 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-Fiit will cloud all battery and inverter data to our cloud
server,
enabling users to remotely monitor their power system.
Warning
It is important to note that working with high-voltage systems is

installation
WARNING
This product may only be installed by a qualified electrician. 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 flat inside a cabinet. When
installing on a wall ensure you use Rawl boats to secure the unit to the wall.
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 specification.
DIP SWITCH SETTINGS
Configure 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.
multiple batteries
To connect multiple batteries, ensure you use the supplied RJ45 to RJ45
(standard LAN cable) and plug one end into the master “Battery Link”, and the
other end into battery #2. Continue this step until all the batteries have
been linked up Continue to wire up the DC block terminals of each battery to
the inverter/charger. Once you have completed the address configuration,
inverter-battery communication links, and wired up the DC connections you can
proceed to configure the inverter charge settings.
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 configuration 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 diagrams for the correct method of linking multiple batteries
in parallel. Diagram 1, displays a standard linking connection. Diagram 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 firmware updates directly
for the BMS. This port cannot be used for any inverter communications.
RS232 COMMUNICATION PORT
The RS232 interface is used to connect to either the Hubble Cloudlink device
or for technical support 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 catastrophic fire hazard. Therefore,
interfacing to the BMS directly without authorization will void the warranty
and Hubble Lithium will not be liable for any resulting damages.
OPTIONAL 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.

INVERTER SETUP
PRE-LAUNCH INVERTER SETUP
Set your Inverter/charger to the corresponding settings below before you
start charging or using the lithium batteries.
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
IMPORTANT NOTICE:
SET THE VOLTAGES CORRECTLY AS OUT-OF-RANGE VOLTAGES CAN DAMAGE THE BATTERY.
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 correct 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 layouts under the “Inverter Guides” tab on our website:

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

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/discharge capacity, charge/discharge current,
temperature, etc. This can be downloaded by a service technician to help
troubleshoot any issues or problems with 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 are near full charge.
Thus, it is critical that a full charge to the batteries is provided at least
once every 5 (five) 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 guaranteed 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.
