I went from getting hot water in 1 minute to having hot water in 2 seconds at my kitchen sink. I want to put in the additional sensor valves to get scorching water at different locations.

You still have to take the 240v that comes out of the microinverter and transform/rectify it to charging voltage for the batteries. So the microinverter just adds another 8% loss to the system, compared to a DC-out MPTT controller like FlexMax 80. Also, much of Andalay's propaganda is bogus -- nobody in their right mind has 600 VDC wiring, shadows on one panel don't affect the output of other panels, etc. Yeah, this system makes sense if all you want to do is pretend to sell electricity back to the grid (note: they might buy it, but it doesn't really go anywhere except into heat at the first transformer), but if you actually want to USE the generated electricity, a conventional system is much more efficient.
