>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.
