[RE-wrenches] Enphase / Inverter failures

[matt at solar-energy-solutions.com]

Corey,

Thanks for sharing this helpful information.  I decided to test M190s on
my shop in early 2010 before offering a new product.  Until about 8 months
ago, when we started seeing engineers specify Enphase, I refused to
install more of the units.  My breakdown in Midwest climes:

- M190 - 9/15 = 60% failure
- M215 - 1/146 = 1% failure
