Discussion Overview

The discussion revolves around connecting a photovoltaic (PV) module to the electrical grid. Participants are exploring the necessary circuit diagrams and regulatory considerations involved in this process, with a focus on practical implementation and safety standards.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant has designed a PV module in Simulink and is seeking a circuit diagram for connecting it to the grid.
  • Another participant suggests using Google to find existing articles on connecting photovoltaic modules to the grid, implying that there is a wealth of information available.
  • A participant expresses frustration with the search results, stating that they mostly contain statistics rather than practical circuit diagrams.
  • Further advice is given to search specifically for "grid tie inverter schematic circuit diagrams" to find relevant information.
  • One participant emphasizes the importance of understanding and complying with regulations that electricity suppliers require for connecting a PV system to the grid, highlighting health and safety concerns.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best approach to find the necessary circuit diagrams. There are differing views on the adequacy of existing resources and the importance of regulatory compliance.

Contextual Notes

Limitations include the lack of specific circuit diagrams provided in the discussion and the potential variability in regulations depending on the electricity supplier.

I am working on a project. I have completed designing PV module in simulink. I have also added MPPT algorithm and Boost Converter. Now I want to connect it with a grid. Can anybody tell me the circuit diagram?

mukesh.sehwag, Welcome to Physics Forums!

Using Google Search with the terms "connected photovoltaic module with grid" I found many articles describing how to do this. Why don't you investigate how thousands of others have successfully made this interface?

If you do this research and still have any technical questions or doubts, then return here and post them.

Thanks for replying.

I did search before posting here. But what I got are all statistics showing how much produced and like that. Okay I am still searching. If I have any problem I will reply back.
 
OK, mukesh.sehwag. Will you please try to Google search using these terms: "grid tie inverter schematic circuit diagrams". See if what you need can be found there.

If this is a practical project and if you really want to connect to the grid then you will need to read the regulations that you will need to satisfy before your connection is 'approved' by your supplier. Electricity suppliers are obsessed with Health and Safety (rightly so) and will not let anyone connect a PV system that is not thoroughly checked out (and probably type-approved).
