powering a billion dreams…Solar – DC Inverter-less UPS Cygni – Solar-DC solution CYGNI, an Incubatee of IIT-Madras Incubation Cell and Rural Technology Business Incubator of IIT-Madras. CYGNI in collaboration with IIT Madras has developed the high efficiency Solar- DC solution. The Solar-DC Inverter-less UPS is a power back-up solution. This replaces the existing Inverter used in homes. This innovative technology results in significant reduction the power back-up cost, almost 30-40% lower cost than the exiting Inverters used in the market. The DC solution seamlessly integrates Solar, so that additional solar power can be added incrementally based on the customer need. Due to Energy Efficient DC equipments, the customer monthly power bill also gets reduced by 50%, which unlike in inverters, increases the cost of power bill. Owning and managing the solar supply chain, places CYGNI in a niche position to pass significant savings to our customers. CYGNI has an experience of system integration projects include rooftop systems and decentralized applications. Why Inverterless? Solar PV gives DC Power Solar But load is AC Needs a DC-AC convertor DC Now if we add a battery DC-AC grid Battery PCU / Inverter Load AC AC-DC DC-AC stores only DC Require a AC-DC convertor for charging Require a DC-AC convertor during discharging For low power. each convertor* can have 10 to 15% loss battery Solar with battery may have 25 to 45% loss . DC Advantage Basic Home Loads are moving to DC Equipment Fan Tube Light AC (Watts) DC (Watts) At Full Speed (Speed 5) 72 30 At Min. speakers AC to DC conversion has losses from 20% to 50% in each device Refrigerators. air-conditioners. washing machine moving to BLDC motors . speaker-phones. laptops.
