Solar – DC Inverter-less UPS

powering a billion dreams…

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  But load is AC  Needs a DC-AC convertor

  Now if we add a battery  Battery 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  Solar with battery may have 25 to

45% loss

DC Advantage   Basic Home Loads are moving to DC

  Electronics devices work on low-voltage DC   TV (LED/LCD), laptops. Cell-phones, speaker-phones, tablets, speakers   AC to DC conversion has losses from 20% to 50% in each device

  Refrigerators, air-conditioners, washing machine moving to BLDC motors

Cygni’s Inverter-less UPS

  48V DC line as an additional power line at home

  Highly power-efficient usage of Solar

  Low-power from grid alone converted from AC-DC   Designed to have minimal

loss

  Battery can be added with higher efficiency (no convertors), if required
