Anyone have a SolarEdge StorEdge battery interface installed?

    I just now looked for installation stories that weren't just
    a press release or news story. It took a while, but the query
    powerwall installed solaredge forums.tesla.com
    finally dredged one up... from the *third* installation in Vermont
    Evidently Green Mountain called him at random and
    offered to include him in their pilot, perhaps because
    he's out in the sticks and has lots of outages (he doesn't
    have solar, too much shade):

    He said it kept his water pump, refrigerator, several lights, and
    both routers running during a 16 hour outage. But it doesn't
    really count, as it was part of the pilot, and it wasn't an upgrade.

    So, early days yet. Still waiting to hear about someone who's
    actually upgraded a solaredge to add a battery.
    I knew it was somewhere in New England. I just could not remember which POCO and which state exactly. Thanks for the correction.

    I know that Tesla was using that area as a test bed for their Powerwall but I have no idea how well they work there or if they are financially a good decision since the electric rates are not as high as places like CA and HI.

      Electricity in New England is generally more expensive on average than in CA.

        greenmountainpower.com/wp-content/uploads/2016/09/Rate-1-Residential-Service-10.1.16-1.pdf says $0.43/day plus $0.15/kWh

        But the pilot customer said he has lots of outages out where he is in the sticks, maybe that makes it attractive.
        17kw. I like science, but I'm no expert.

          Seems to me that the basic rate for Green Mountain residential is less than $0.15/kWh. While I thought the lower rates for most CA POCO's was in the low $0.20/kWh. I am not sure if that is true but I doubt the powerwall has a quick payback in Vermont.

          Even as an emergency power backup I don't believe the cost of a battery is cheaper then the cost of an emergency generator for power outages.

            The big CA POCO's are around $0.20/kW and up to 2X that depending on tariff/tier/T.O.E. Smaller co-ops can be less, but $0.15/kWh ain't that common.

            Part of the deal w/mini site storage, similar to residential PV generation, is that without some intelligent way to figure/guesstimate some long term cost/kWh of non POCO means of storing power, such as LCOE analysis, talking about cost effectiveness is all just jaw jacking anyway.
