Why install a SIRIUS CAPACITOR MODULE instead of chemical batteries.

Fast Charging

Sirius Practically Charges as Fast as your Inverter or Charger Allows – Eliminates the Need For Large Battery Banks

The Sirius Super Capacitor Module can theoretically be charged in less than 32 seconds without affecting cycle life.
Various models are available with different charge and discharge ratings, ranging from 1C to 135C.
The popular model in the Solar PV and Home use market is the 1.35C Model, which means the unit can be fully Charged or Discharge 1.35 times in an hour.
This is faster that any normal application in the Solar PV and home use market will require.
You can charge and discharge the 1.35C model in 44 minutes, which makes this well suited even for sites where you energy storage is recharge by generator of the grid from time to time.

Faster charging models delivers significant advantages in a wide range of deployments such as in electric vehicles or utility grade frequency regulation.
An infrastructure of fast-charging stations eliminates the need for large battery banks with extended range.
Fast-charging of the Sirius provides utilities with real time response capability to frequency regulation.



Increases Energy Density and Operating Voltage

Sirius’ proprietary algorithm-based balancing, charging and control circuit actively balances and stabilizes the system, delivers deep cycle and long duration discharge and specific energy of 80 Wh/kg. Therefore, in addition to standard fast charge / discharge usage, the Sirius storage system can be deployed at industry voltage, in applications requiring deep cycle discharge including electric vehicles.


High Efficiency

Number Of Batteries & Ultra Low Impedence

  1. With a Depth-of-Discharge (DOD) of 100% and round-trip efficiency of 99.1%, the Sirius battery’s delivered and rated capacity are almost the same, allowing for a significant reduction in the number of batteries required when compared to systems utilizing chemical batteries, thereby lowering capital investment.
    In other words, you can use the full rated kW capacity without ever damaging the unit.
  2. Due to the very low Impedance of the SIRIUS, up to 10 units can be placed in parallel before ripple current needs to be considered.

Cycle Life

Lower Cost of Ownership

The cycle life of the Sirius storage system is 1 million cycles at 100% DOD with negligible capacity fade and impact of charge / discharge rates. Combined with very low maintenance requirements, Sirius delivers power and energy at an unmatched cost per cycle.


Temperature Range

Enables Usage in Most Environments

The SIRIUS can operate between -30 deg Celsius and +85 deg Celsius.

With a temperature tolerance range that is higher than most chemical batteries, the SIRIUS can be deployed in extremely harsh environments without cooling or heating, resulting in less oversight and maintenance.

The foremost reasons why chemical batteries do not reach there stated usage cycles are depth of discharge and temperature.

SIRIUS will never disappoint you on either of these aspects.
You can discharge to 0% and you can operate at Extreme temperature. 


Charge Retention

A Patented, charge retention circuit, controls energy flows and slows down the typical capacitor discharge to a level where self discharge is no longer of practical concern.

The SIRIUS Super Capacitor Energy Storage Module only self-discharge 5% after 25 days!

Utility Grade Storage

Kilowatt Labs’ Sirius can provide multiple services to the grid to deliver higher rates of efficiency, and more efficient use of capital already invested in the grid infrastructure.

With 99%+ round-trip efficiency, high temperature tolerance, 1 million charge cycles, 100% DOD, long duration discharge, fast-charge capabilities, Sirius provides an array of support services when connected to the grid, either by devoting all its capacity to a single service or to multiple services simultaneously. With the Centauri Energy Server, the service mix that provides the optimal benefit to the grid in real time can be determined and supplied. The Sirius battery offers solutions for frequency regulation, renewable integration, T&D deferral, spinning reserve, peak shaving, ramping support and voltage support.

Electric Vehicles

Bringing Instant Mobility to the Electric Vehicle Industry.

With a charging time of less than 15 seconds, the Sirius battery enables instant mobility to electric vehicles, putting them at par with a combustion engine car. With an energy density of 115Wh/kg of delivered energy, a cycle life of 15,000 cycles, high temperature tolerance and low cost, Sirius battery enables electric vehicles’ attributes to exceed combustion engine cars for the first time.

The Sirius battery can be deployed in all kinds of vehicles, 2 and 3-wheel vehicles, passenger trucks and buses, trains, trams, SUV’s, industrial vehicles, and military vehicles.

Behind-The-Meter Residential, Commercial And Industrial Solutions

Sirius storage can be deployed in demand charge reduction applications, with unmatched technical and economic metrics. It can be deployed as a resource in demand response programs instead of fossil fuel alternatives. Together, with the Centauri Energy Server and PV solar, it can be deployed to provide 24×7 power in territories that have high tariffs, and discontinued NEM programs.

The Sirius battery can be deployed in homes, commercial establishments, factories, refrigerated containers, and telecom towers.
