2. Hybrid inverter is also known as smart grid inverte r Hybrid inverter is a new generation of dedicated U.P.S (uninterepted power supply) using renewable energy for home consumption , especially for solar photovoltaic installations . Renewable energy (solar energy , wind energy etc) sources plays an important role in electricity generation. An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the resulting AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits. INTRODUCTION

3. HYBRID INVERTER WITH SOLAR POWER SYSTEM Hybrid inverter with solar power system is an advance system in which solar power and conventional electric power. This Hybrid inverter with solar power system is comprises of ac to dc converter to charge battery from 220vac supply . This charging system is consists of transformer, rectifying diodes and some electronics components. Dc to dc voltage and current controller circuit is used to control charging from solar panel

7. Solar panels absorb the sunlight as a source of energy to generate electricity or heat . A photovoltaic (PV) module is a packaged, connect assembly of typically 6x10 photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential application. SOLAR PANEL:-

8. Needs Of Solar Power Electricity rate has hiked in last four years. We need to focus on alternate option because of environmental concerns. It has several advantages over other forms of electricity generation. A Solar Inverter

9. An electric battery is a device consisting of one or more electrochemical cells  with external connections provided to power electrical  . When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the  anode. The terminal marked negative is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. BATTERY :-

10.  A  relay is an  electrically  operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal RELAY :-

11. Cost efficient. Reduce pollution. Low maintenance. Power management. Automatic system. DISADVANTA GES Solar energy is only available during day time. Freqency adjusting is difficult.

12. DC power source utilization applications include use of DC in motor vehicles and from batteries to power AC loads and use of energy from solar cells to power AC loads. Use of inverters in uninterruptable power supplies (UPS) allows energy to be stored as DC in batteries and used as AC when needed. In industrial equipment such as AC motor speed controls and induction heating equipment AC is converted to DC and then converted back to AC at a different frequency or an adjustable range of frequencies. Inverters are used in some battery powered electric vehicles and in hybrid vehicles to change DC to adjustable frequency AC to control AC motor speed. APPLICATIONS

13. I nverters are usually about 95% efficient. Inverters play a significant role in providing alternate current supplies at the times of crucial power requirements. The primary use of solar inverters is to convert direct current to alternating current through an electrical switching process. CONCLUSION

14. The wind & solar hybrid inverter consist of solar panel , wind turbine , controller , inverter & batteries , all of which can function independently without utility power. The wind solar hybrid system are now being used widely in different fields , like street lighting , traffic , telecommunications base , large scale billboards & home power. FUTURE SCOPE
