About Inverterless





WHAT IS A INVERTERLESS PRODUCT for Homes?

Inverterless is an innovative smart power back-up solution for your homes. This product is a cost effective alternative to bulky and inefficient Solar based inverters that are used at home today. Inverterless saves 50% of your electricity bill through intelligent use of solar, battery and energy efficient DC equipments. This power back-up system for homes uses Solar-DC, a technology developed in collaboration with IITM, provides a 48V DC as a power back-up line that provides uninterrupted, continuous power. This line enables use of energy efficient DC appliances such as BLDC fans and LED lights, resulting in substantial reduction in energy consumption and provides significant cost savings to the consumer.

  • Advantages for Builders, Apartment and Commercial Complex Owners.
  • Reduced power consumption by 50%.
  • 24x7 Uninterrupted Power supply.
  • Low cost and occupies less space.

below is the difference between Solar DC and conventional Solar AC

Parameter48v DC Inverterless SolutionConventional AC Solution
Technology Inverterless unit provides efficient DC power system for houses and office spaces. The Solar and the Rectified Grid power are efficiently shared in a manner to maximizing Solar power usage Conventional systems use DC to AC and AC to DC to charge Batteries, and DC to AC inverters to supply 230V AC. This results in multiple conversions resulting in inefficient and significant losses in power.
Efficiency The new DC-power appliances such as fans and light are highly efficient, resulting in less than 50% power consumption Normal AC appliances convert AC back to DC, resulting in losses and are inefficient compared to DC counterparts.
Overall power saving 40% to 60% overall power saving is possible Compared to conventional systems,even saves 50% of the space. Conventional AC systems would need up to 60% larger solar panel and batteries, resulting in higher inefficiencies, Costs and space requirements.
Safety Falls under SELV,as all devices work with 48V, Reducing risk of electric shock. Devices and inverter operate at 230V,adequate precaution Should be taken as in normal AC System.

HOW DOES INVERTERLESS DC SYSTEM WORK?

During day time it takes energy from Solar and during Night times it takes energy or power from AC 230V(Electricity Board),means Inverterless System will convert 230V AC Power into 48V DC Power,when both are not there means Solar and Normal AC Power are not there then Battery Bank will comes into picture.

Why DC appliances?

A normal AC fan used at home typically consumes 72W, whereas a DC-powered BLDC fan consumes only 30W at full speed. At lowest speed, an AC fan may consume about 60W, whereas a BLDC fan will consume about 9W. Similarly, a CFL four feet tube-light consume 36W, whereas an equivalent DC-powered LED tube-light consumes only about 15W; it can also be dimmed to consume about 3W. All electronics TV, laptops, cell-phones, tablets etc. use DC alone. The AC- DC adapter that we use has losses of 30% to 50%. A DC-powering will reduce losses to less than 10%.

 

Technical Benefits:

  • By using DC 48V Solution, we can avoid power conversions & power losses by avoiding unnecessary power conversions by upto 60%.
  • No carbon foot prints, 100% Green energy.
  • 48V DC falls under Safe Extra Low Voltage (SELV); thus no shock, reducing risk of electric shock and no fire accidents.
  • Controlling/Monitoring of loads with IR Remote controls.
  • Monitoring power saving & readings in Energy meter.
  • High efficiency.

Commercial Benefits:

  • Energy savings with energy efficient DC appliances.
  • Reduction in monthly electricity bill up to 50%.
  • Low cost & more effective compared to equivalent Solar AC solution.
