No. I believe it is scheduled for the 2nd half of 2015 in the U.S. I've seen anticipated pricing (a guess) around $800.JimSouCal wrote:I remember it being announced. Is the Enphase AC battery out for sale in the marketplace and considered back behind leading bleeding edge? I am game to try..
I think it will be the easiest choice available for homeowners wanting to do some TOU shifting. The new S275 microinverter which is included apparently has power factor correction capabilities. Who knows how much the new Envoy will run to control these things. IMO, the software will be very important and likely will take a few iterations to get working correctly. (And, yes, the software can destroy or severely shorten the life of the batteries if done improperly.)

The Tesla battery does not include an inverter, so you need to add another few percent loss for that (each way unless you are charging directly from DC PV).DanDietrich wrote:I use enphase microinverters on my system, and the tech sheet for the Tesla battery shows a 94% efficiency, so converting my ac to dc and back again costs me another 6% of my power if I use the battery.
I'm all for this stuff, and I don't mind that Tesla gets all of the attention while Nissan sells more electric cars, but this unit isn't really practical or cost effective in many situations. No one in this thread yet had mentioned the power loss due to conversion, and I think that is fairly important to keep in mind as a recurring expense.
