Q. How to reach the rated capacity of Module?
A. The display shows the total delivered energy (discharged) from the time the Module started till
current time, and the Module has ~70A at 1C and 125A at 1.7C(Max. charging current). So, to obtain
the standard energy 3.55kWh, start the charging cycle from minimum voltage 44V to maximum
voltage 54V with constant current of 70 A as shown in charging curve of Sirius module, then for
discharging cycle start from maximum voltage 54V to minimum voltage 44V with 70 A constant
current. (Please refer to Sirius VIEW application manual for Round trip efficiency).
Q. What would be the effect on energy when charge/discharge the Module at different C-ratings?
A. When the charge rate increases, the time for charging/discharging decreases, which means that
maximum energy can be obtained in a short period of time as shown in the table below.

Q. Why the Module needs twice of power cycle?
A. When the Module is switched OFF and the Sirius VIEW is still open you have to wait for 10 Sec
(since the application is still communicating with the Module) before turning ON the Module, or either
by terminating the Sirius VIEW or by disconnecting the communication cable.
Q. How much is the capacity of the internal storage (SD Card)?
A. 8GB SD Card is used in the Module which logs 85 bytes of data per 10 seconds. Note that data
logging should be turned ON before the Module will start logging and data logging is limited to 30
days. After reading the data the Module will delete it automatically. By default, data logging is OFF for
firmware version 2. 0 and above.
Q. Do I need to use Sirius VIEW Software?
A. The Module can work stand-alone without the software however, the software can be used to
monitor and extract the data & measurement as well as to enhance the performance of the Module.
Q. How do I know if there is firmware issue in the Module?
A. Please refer to Sirius VIEW monitoring software manual Configuration of Module and Software
section.
Q. What kind of issues can happen about firewall and antivirus programs?
A. There will be no problem as far as the software run as administrator.
Q. How to calibrate Module parameters?
A. To calibrate Module parameter like (Voltage, Current, Temperature, Energy). Kindly consult with
