Quick Setup
The Hubble is designed to work with 48V UPS and inverter systems and will work under AGM charge
characteristics. For solar inverters that is not on the approved integration list it is recommended to set
your inverter battery parameters manually to ensure your battery operates at optimal levels.
It is highly recommended to study the manual before installation, however for quick setup and startup of
the Hubble Lithium pack, follow the following steps:
1. Ensure cuircuit breaker is in the OFF position
2. Securely connect the DC cables to the terminals ensuring correct polarity.
3. If the unit is in sleep mode (LED lights off), press and hold RESET button for 3 seconds. The LED's
will light up.
4. Switch on DC breaker.
Inverter setup for Axpert King & VMIII (with BMS port)
The below settings is for setting up Axpert type inverters that does not have the lithium comms port.
Item Settings Value
Program 02 Maximum charge current
The Hubble is set to charge at a maximum rate of
21Amps.
Multiple batteries (2 or more) can be setup as as
20Amps x (amount of Hubble units).
Program 05 Battery Type USE
Program 12 Voltage point back to Utility 48V
Program 13 Voltage point back to Battery 51V
Program 26 Bulk Charge Voltage (C.V.) 53.2V
Program 27 Float charge voltage 51.2V
Program 29 Low DC cut-off voltage 46V
The Hubble has full integration with the Axpert King and VMII type inverters and other Axpert type
inverters with a BMS comms port.
To setup the Axpert King or VMIII, ensure you have at least firmware version 02.49 installed on the King
or VMII inverter. If you do not have this version please request it from your inverter supplier.
Connect the communications cable into port RS485-A and the other end into the Lithium RS485 port on
the inverter. Ensure you have the cable connected the correct way around as each side has a different pin
layout.
After the Lithium is connected and the inverter is powered on, change setting 5 in the inverter setup to
"Lib". This will enable the Lithium battery communication.
It takes up to 120 seconds to syncronize the communication. Once the battery icon on the inverter
flashes, communication has been successfully setup. No further settings or setup is required as the
battery will communicate to the inverter what charge, cutoff, float, bulk charge voltage should be used.
