[RE-wrenches] Apparent Micro Inverters

[R Ray Walters]

If its a large commercial array, I would consider using larger centralized inverters, and then monitor with National Semiconductor's Solar magic monitoring system. It has string level current taps, so (theoretically at least) you could see a single module failure by the reduced string output. 
I like the idea of medium sized inverters to take each subarray that has a different orientation.
Solar PRo magazine had a great article comparing centralized inverters to multiple smaller units. (Dec/Jan 2009)
My ideas on this are still under development though. There are many factors to consider, and different projects will have different best solutions.
