Installation
Multiple Batteries
To connect multiple batteries, use the supplied RJ45 to RJ45 (normal LAN cable) and plug one end into the master Battery Link and the other end into battery #2. Continue this step until all batteries are linked up. Then, wire up the DC block terminals of each battery to the inverter/charger. Once you have completed the address configuration, inter battery communication links and wired up the DC connections, you can proceed to configure the inverter charge settings.
Note : 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.
Warning : 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, while Diagram 2 displays parallel batteries to which the negatives and positives are connected to common buzz bars.
The AM-4 is designed to be wall mounted or installed flat 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 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 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 configuration, inter battery communication links and wired up the DC connections you can proceed to configure the inverter charge settings.
NOTE: BATTERY LINK CABLE
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.
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. Digram 2, displays parallel batteries to which the negatives and positives are connected to common buzz bars.
Communication Ports
The AM-4 has an RS232 communication port that connects to the Cloudlink device or is used for technical support to interface directly through a service laptop and access the BMS for programming and troubleshooting. Learn more about the Hubble Cloudlink at https://www.hubblelithium.co.za/hubble- cloudlink.html. Access the latest Cloudlink Setup Guide at https://www.hubblelithium.co.za/cloudlink-setup.html.
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 configuration
that the Hubble battery CAN bus port uses. Ensure you have the pin out for the
cable required for your inverter.
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.
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.
LED Indicators
When the 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, and the BMS will reset. The LEDs will flash one at the same.

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 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.
