2. About CYGNI

3. Cygni
 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 equipment's, 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.

5. Advantages with 48V DC Inverterless
Solution
• With low wattage DC Appliances.
• Highly efficient when compared to conventional AC System.
• Remote controlling for lighting & Fans.
• You can monitor the entire System with the advanced remote monitoring Android Mobile app.
• 50%-60% reduction in monthly Electricity bill. SAVE MONEY-SAVE POWER-SAVE ECONOMY.
• Reduction in unwanted power conversions (AC-DC & DC-DC conversions) & reduction in power
losses.
• This system falls under Safety Extra Low Voltage(SELV), thus reducing the risk of electric shock.
• This 48V DC Inverterless Solution will occupy less space when compared to Solar AC System.
• You will use & encourage latest technology as Solar-DC Inverterless technology, conceptualized
and ideated by IIT Madras.

6. • Electronics devices work on low-voltage DC
• TV (LED/LCD), Laptops, Cell-Phones, Speaker-Phones, Tablets,
Speakers etc.
• AC to DC conversion has losses from 20% to 50% in each device.
• Refrigerators, Air-Conditioners, Washing Machines and many
appliances are now moving to BLDC Motors.
