WARNING:
Working with high voltage systems is dangerous. Do not attempt to modify
your inverter and battery setup unless you are certain you understand the risk.
Speak to a qualied electrician if you are unsure.

WARNING
This product may only be installed by a qualied electritian. The unit is not designed to be installed upside
down or sideways on a wall.
The AM-4 is designed to be wall mounted or installed at inside a cabinet. The unit is not designed
to be installed upside down or sideways on a wall. When installing on a wall ensure you use Rawl
bolts to secure the unit onto the wall.
DC ISOLATOR
The Hubble AM series of batteries have 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 battery. Please ensure you use the correct rating as per battery specication.
DIP SWITCH SETTINGS
Congure 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 1 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 (normal 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 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
conguration, inter battery communication
links and wired up the DC connections you
can proceed to congure the inverter charge
settings.
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. Digram 2, displays parallel batteries
to which the negatives and positives are
connected to common buzz bars.
DIAGRAM 1 DIAGRAM 2
NOTE: BATTERY LINK CABLE
If you do not have a battery link cable or the cable
provided is an insufcient 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 conguration 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%.

COMMUNICATION
PORTS
CAN Bus Setup (optional)
The 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. The Hubble range of lithium batteries with
CAN bus port can integrate with most leading inverters. For more information on CAN bus and
compatible inverters see our website at www.hubblelithium.co.za for more information.
To connect the CAN bus cable from the battery to the inverter, ensure you have the correct pin
layout. The below is the pin conguration that the Hubble battery CAN bus port uses. Ensure you
have the pin out for the cable required for your inverter.
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 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.
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.

RS232 COMMUNICATION PORT
The RS232 interface is used to connect to the Cloudlink device or the port is reserved for technical
support to interface directly through a service laptop and access the BMS for programming and
troubleshooting.

LED OPERATION STATUS
LED FLASH STATUS
When battery is turned on you can reset the BMS operation mode to default to clear a temporary alarm status.
Push the switch for 6 seconds, the BMS will reset. LEDs will ash one at the same.

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
ESD:
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:
Complies with Lever A of YD/T 983-1998 (EN55022).
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 life 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 7 (seven) 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.
