Supercapacitors energy storage systems

Sirius, the Kilowatt Labs® supercapacitor storage system, is the first solution available on the market that delivers deep cycle discharge, long duration discharge as well as fast charge / short discharge, along with all the inherent advantages supercapacitors have over conventional chemical batteries.


It can replace immediately any present solution based on lead (AGM, GEL, flooded acid) or Lithium-Ion (any type)



• High efficient storage system, (99%) no heat dissipation. No need cooling or ventilation

• Operating Temperature -30ÆC to 85ÆC without degradation

• DOD 100% - Nominal capacity delivered independently from the current rate nor the ambient temperature

• Lifespan of 1 million cycles @ DOD 100%

• Available in 12V and 48V

• Can be used with standard AGM lead battery charger

• Active BMS included

• No needs of any special shipping care for “dangerous goods”, like Lithium does

• CE Certifications: 2006/95/EC Low Voltage Directive; 2004/108/EC Electromagnetic Compatibility Directive; Safety Standards EN Norms: EN60384-1:2009, EN60384-4:2007, EN55022:2006+A1:2007, EN61000-3:2006+A2:2009, EN61000-3-3:2008, EN55024:1998+A2:2003, EN61000-6-1:2007, EN61000-6-2:2005, EN61000-6-3-2007, IEC60384-14:2005
