Introduction
The Sirius Capacitor Module (“Sirius”) is supercapacitor-based storage that uses supercapacitors as storage
cells instead of chemical cells. Kilowatt Labs’ proprietary balancing, control and charge retention algorithms
control the operation of the supercapacitor-based Modules, making Sirius a safe, efficient and effective
alternative to chemical batteries wherever chemical batteries are deployed.

The Bypass Circuit breaker is used to bypass electronic switch. It is used for Series connection and recovery of
the Module.
3. Fault Reset:
Fault Reset is a push button which is used to turn ON the terminal manually after it turns OFF due to any error.
The additional features of fault reset are as follows:
a) Hold fault reset for 5 seconds to toggle the terminal.
b) Hold fault reset for 3 seconds to reset fault if there is/are any.
c) We can set the Current reading to zero.
d) Press fault reset button to check the state of charge and instantaneous power.
e) Press the fault reset button to see the individual cell voltages.
•Checking for Individual Cell Voltages:
When the fault reset button is pressed, the LCD after displaying the state of charge (SOC) and instantaneous
power, will display the cell voltages of the first four cells as shown below:
Whereas:
01=Voltage of 1st Cell
02=Voltage of 2nd Cell
03=Voltage of 3rd Cell
04=Voltage of 4th Cell
By continuously pressing, the cell voltages will be displayed for all the cells.
•Enabling/Disabling Cell Balancing:
After scrolling through the individual cell voltages, cell balancing can be enabled/disabled by the following
steps below:
Step 1: When current is zero, LCD will display the message as illustrated below.

Step 2: After this message appears, hold fault reset button for 5 seconds, then the LCD will display the
following message which means that the cell balancing has been enabled.
Step 3: To disable cell balancing, when current is zero, the LCD will display the following message.
Step 4: After this message appears, hold the fault reset button for 5 seconds, then when the LCD displays the
following message, it means that balancing has been disabled.
Step 5: To make the current zero, follow the steps below:
→When current is not zero, the LCD will display the following message.
Note!
To enable and disable balancing, the Current should always be zero.
Note!
Balancing is automatically disabled if there is a Current reading
greater than zero.
