Thursday December 6th, 2012:
Alan Santos-Buch’s lecture on AC Coupling was extremely informative and educating, and the chat session / Q&A were really alive with activity.  Here are a few questions from participants:

Will it be suitable for an inductive load?

What’s absorbtion voltage?

Does the grid charge the batteries during non-outage?

Can this equipment except a wind turbine input?

Can you combine a wind turbine or hydro in the system as a back-up?

Alan answered all these questions and more, reviewed the Wire Diagram, and gave the audience a great introduction to AC Coupling during the lecture.  Watch the lecture video above to get the answers to the above questions and others.
