[RE-wrenches] Tesla Powerwall

[August Goers]

Hi Jon,

We've installed Powerwalls in combination with a good handful of different
PV inverters including SMA Sunnyboys, SolarEdge, Fronius, Enphase, SunPower
SolarBridge MIs, and ABB/PowerOne. They have all worked fine. Of course the
true test is how well they AC-couple during a grid outage. We do a thorough
commissioning test including making sure that the inverters AC-couple
during a simulated power outage, and those have checked out. We've had a
number of power outage events throughout the Bay and for the most part the
systems have worked well. The Powerwall system has all in all been very
impressive.
