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 qualified electrician if you are unsure.

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-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.
Batteries
To connect multiple batteries, ensure you 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 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
CAN Bus Setup (optional)
The AM series models have 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 the 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. 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 DOES NOT CONNECT THIRD-PARTY DEVICES.
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 with 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
LED OPERATION STATUS
LED FLASH STATUS
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, the
BMS will reset. LEDs will flash one at a same.
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. (the 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).
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/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 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 at 100% state of charge when the batteries are 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.
Completing Setup
Once all the above steps have been completed you can proceed to follow the start-up instructions given by your inverter manufacturer.
If you have any difficulties with setting up your system, please contact our Technical Support Department via support@hubblelithium.co.za. Be sure to include the following information in your initial email so that we can provide you with timely assistance:
- Inverter make & model
