The document discusses the installation of a 5 kW on-grid solar power plant using a net-metering system and solar inverter. It describes the different types of solar systems based on the inverter used - on-grid, off-grid and hybrid. On-grid systems can operate without batteries or with batteries for backup. Off-grid systems include batteries for backup when the grid is down. Hybrid systems combine solar with other renewable sources like wind or generators. The document also examines the advantages of different inverter types for on-grid systems - micro, string and central, concluding that grid supportive solar PV provides economic and eco-friendly electricity production.

11. ON-GRID Without battery

12. Advantages of ON-GRIDWithout battery(large scale)
• One time investment.
• Less maintenance required.
• Higher lifetime due to absence of battery.
• Grid-tie inverters are designed to shut down automatically uponloss
of utility supply, for safetyreasons.
Disadvantages of ON-GRIDWithout battery(large scale)
• They do not provide backup power during utilityoutages.

13. ON-GRIDWithbattery(smart grid concept)

14. Advantages of ON-GRIDWithbattery(smart gridconcept)
• They provide backup power for plant.
• Grid-tie inverters are designed to shut down automatically upon loss of
utility supply, for safety reasons.
Disadvantages of ON-GRIDWithbattery(smart gridconcept)
• Maintenance required withproper schedule.
• They do not provide backup power during utility outages for Grid.

15. Off-GRIDPV System

16. Advantages of Off-GRIDPV System
• They provide backup power for plant.
• No requirement of grid supplyto stay ON.
Disadvantages of Off-GRIDPV System
• Cost is increaseddue to presence of batteries.
• Proper maintenance required.

17. Hybrid PV SystemwithDG set

& GRID

19. Advantages of HybridPV System
• it gives option for additional power though DG set or windpower.
• very cheaper than others.
• it is for bothON & Off grid.

20. Types of GridTiedInverters
There are mainthree types of this inverters:-
I. MICRO INVERTERS
II. STRING INVERTERS
III. CENTRAL INVERTERS

21. MICRO INVERTERS
• A micro-inverter consists of a small box located on the back of or
situated very close to a solar panel. Its role is to convert the DC
electricity produced by a singlesolar panel.

22. Advantages of Micro Inverters
• Gives panel level MPPT due to no transmission of LVDC.
• eachpanel is separated by each other.
• Panel level monitoring
• increase safetybecause no HVDC transmission.
• Less maintenance required.
Disadvantages of Micro Inverters
• Higher costs in terms of dollars per watt
• Increasedcomplexityin installation

23. STRING INVERTERS
A string inverter is the type most commonly used in home
and commercial solar power systems. It is a large inverter box that is
often situated some distance away fromthe solar array.

24. Advantages of String Inverters
•Robust
•3 phase variations available
•Low cost
•Remotesystemmonitoring capabilities
Disadvantages of String Inverters
•No panel level monitoring.
• highrisk due to HVDC.

25. CENTRAL INVERTERS
Central inverters are designed for applications such as large
arrays installed on buildings, industrial facilities as well as
fieldinstallations – they are basicallyjust a very large string inverter.

26. Advantages of Central Inverters
•Low capital price per watt
•Comparative ease of installation
Disadvantages of Central Inverters
• Bulky in Size.
• Noise.
•A single potential point of entire systemfailure.

27. Advantages of Grid Supportive Solar PV System
 Economical.
 One Time Investment.
 Less requirement of maintenance.
 Eco-friendly.

28. Conclusion
From this project we observed that this solar inverter is producing
electricity free of cost by using solar energy so, its eco- friendly, pollution
free and can be used for domestic appliances as well as for industrial
purpose on three phase.
