SECTION 1: INSTALLATION

WARNING
This product may only be installed by a qualified 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 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 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

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

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 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 firmware 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 Cloud link 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.

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.

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.

INVERTER/CHARGER SETTINGS

BULK / EQUALISATION CHARGE| 53.6 V
FLOAT CHARGE| 53.6 V
LOW DC CUTOFF| 44 V

VERY IMPORTANT NOTICE:
Set the voltages correctly as out of range voltages can damage the battery.

AXPERT RECOMMENDED SETTINGS

VOLTAGE POINT BACK TO UTILITY| 47 V| Axpert Type
VOLTAGE POINT BACK TO BATTERY| 53 V| Axpert Type

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.

PLEASE NOTE: INVERTER SETUP GUIDES
If you are setting up a non-expert type inverter, for example Daye or Sensing – please navigate to the Inverter Setup Guides tab on our website and select the correct corresponding inverter guide: https://www.hubblelithium.co.za/

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: https://www.hubblelithium.co.za/

The below is the pin configuration for the Hubble battery CAN cable:

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 flash one at the same.

SECTION 4: BMS & MAINTENANCE

MS 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).

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 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.
