- 1. MICRO SOLAR INVERTER Presented By M.KAYALVIZHI J.VIJAYALAKSHMI DEPT OF EEE GANADIPATHY TULSIS JAIN ENGINEERING COLLEGE
- 2. ABSTRACT • In this paper micro solar inverter has been designed and developed that converts DC power to AC power. • The micro inverter is mounted behind the solar panel and the AC power is drawn for use in any place and for any application. • This means simplified installation and management, better reliability.
- 3. SOLAR POWER GENERATION • Produces a DC power. • Depends on module design and lighting conditions. • Modern panels using 6-inch cells typically contain 60 cells & produce a nominal 30 v & 130kw.
- 4. CHARACTERSTICS OF SOLAR PANEL
- 5. EXISTING SYSTEM CENTRALIZED/STRING INVERTERS Panels are connected in series to produce an array. The power then runs to a central inverter, which converts into standard AC voltage.
- 7. PROPOSED SYSTEM MICRO INVERTERS Eliminates the need for all the modules to be in one place. Each module has its own inverter. Own AC-generating. More the number of modules – The solar system produces more power

- 11. DESIGNING OF MICRO SOLAR INVERTER Square wave circuits. Sine wave circuits. Power amplifier circuits. Supporting loads.
- 15. LOADS • Household appliances. • Low power industrial appliances. • Grid tie applications.
- 17. SYSTEM DESIGN
- 18. ADVANTAGES • Compact in size. • Easy to maintain. • Easy fault rectification. • Less expensive. • Any house hold applications.
- 19. CONCLUSION • Micro-inverters have been most successful in the residential market, where limited space for panels constrains array size. • Produces application-matching power directly at the back of the panel. • Have become common where array sizes are small and maximizing performance.
- 20. FUTURE PLANS • We are in a plan to power up GTEC with the use of micro inverters for the lighting systems...
