1What is Inverterless Technology?
Did you know typical Inverters and solar solutions available in the market wasted almost half the power generated before they power the appliances? This was because of unnecessary convertors that incurred a lot of losses and poor design. Inverterless eliminates the need for these converters by working directly on DC through state of art design. Inverterless is a solar solution that can also act as a power back up whenever necessary. The smart controller built within the Inverterless charges the battery, alarms/switches the loads during an overload condition, reliably powers the load, and most importantly saves energy thereby reducing your electricity bill!“Switch to Inverterless! Switch to a better tomorrow”.

5Why Inverterless Technology? Why Is It Needed?
• Advantages for Residential, Offices, Educational Institutes. • 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 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 of 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.
6How does solar inverterless DC system work?
During daytime, 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 come into the picture.
7Why 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 consumes 36W, whereas an equivalent DCpowered 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 up to 60%. • No carbon footprints, 100% Green energy. • 48V DC falls under Safe Extra Low Voltage (SELV); thus no shock, reducing the 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.
8How does Inverterless Home Rooftop solution as a grid-tie solar installation work?
There are two major components: DPAU (DC Power Augmentation Unit) and BLE (Bluetooth Low Energy). The power from the grid carries 230V AC electricity. This electricity goes to DPAU unit within the Inverterless solar controller where it gets converted into usable 48V DC electricity. It then powers all connected DC electrical load. Surplus energy generated is fed to the battery for charging. The Inverterless solar controller is designed such that power required to run the load is obtained firstly from solar, then from grid & thirdly from the battery.BLE (Bluetooth Low Energy)module present within the smart controller aids in displaying consumption related data onto the user app.
9What happens to Inverterless Home Rooftop solution when the grid fails?
Typical AC grid-tie solar inverters are connected to the grid and cannot work without the grid. When the grid fails, the system also fails to generate any electricity. But with Inverterless Home Rooftop package, the solar power system acts independent and can run all the DC loads connected in the absence of grid failure for given amount of time. This is the ultimate power back solution.
10 How does Inverterless Home Rooftop solution as an off grid installation work?
Inverterless Home Rooftop solution consists of solar panel, Inverterless solar controller, set of battery and DC appliances kit. When sunlight falls on the solar panels, they generate DC electricity. This goes into the Inverterless solar controller and comes out as usable 48V DC electricity to power the connected load. Surplus DC gets stored in the battery for later use. The Solar controller has an inbuilt charge controller which monitors the health of battery ensuring a perfect state of charge at every instant of time. Hence, ensures reliable power supply to off-grid installations.
11 What happens to Inverterless Home Rooftop solution in the absence of Sun?
In the absence of sun or on a partially cloudy day, solar panels cannot make enough electricity, so electricity is primarily taken from the grid to support the connected load.
12Where should “Inverterless Home Rooftop solution”be installed?
Inverterless Home Rooftop package is customized for dual purposes: as a grid-tie solution, as an off-grid solution). Hence, suited for places that are on the grid as well as those completely off -grid. Homes that have good grid-connectivity, but feel the cost of electricity is high or prone to power cuts can install this system. Homes that are completely off-grid or willing to go off-grid can install this system as – they make and use electricity generated from solar.

19DC Microgrid- What is it?
DC microgrid, as a source of power, connects solar panels in series in order to generate power at a comparatively higher DC voltage, which can be transmitted over a small distance. Multiple solar power plants are strategically placed at specific locations within the grid, instead of a single centralized grid, so as to minimize distribution losses. Houses tap into the distribution line with the help of junction boxes and charge controllers for each home. The microgrid charge controller installed in each house steps down the higher DC ‘grid’ voltage, to 12/24/48 V DC as per individual requirement, which is used to charge the storage battery and power the energy efficient DC loads in house.
