[RE-wrenches] Enphase M240

[wmdorsett]

We still have clients who are patiently waiting for sma's 240. Perhaps their commitment to battery based inverters will assure that it will also be supported into power when the grid is down. And while it should be good when it's out, at one their road shows they were still passing around a mock up, promising a july release. They have a dedicated factory in Denver so until then...Fingers crossed.

Here's the test report:

As comparison, here's the SMA micro:

I don't understand why the test voltage ranges seem to be shrinking. The 
M215 was CEC tested at 22, 29, and 36V. The M240: 27, 32, and 38V. For 
the SMA 240: 29.5, 30.2, and 32. It seems to me that a 2.5V testing 
window reduces the value of having a weighted efficiency calculation.
