[RE-wrenches] tesla powerwall

[Jason Szumlanski]

>From what I understand, the Enphase offering will include an inverter
(inverter/charger?). I assume they are using a similar architecture to the
PV microinverters, which is a modular approach to solving the problem. This
will undoubtedly cost more, but will make design and implementation very
easy. The monitoring capability will surely be a major selling point.
