    One of the recent energy sage email blasts had an interesting article about a few utilities in New England running battery storage pilots, where they subsidize the cost in exchange for limited load management rights.

    The idea of battery storage with islanding capabilities is really appealing, but the quoted two powerwalls would have more than doubled the cost of our system, and was more than three times the installed cost of a whole home gas generator. If PSE&G decides to get in on the act, I'd certainly be interested.

    Yeah I explored this option with Tesla when I got their solar quote, but because their overall poor communication and sales process I just put it on the back burner for now.

    It COULD always be added later I'm sure, maybe a little more complicated connection, but hopefully the pricing might come down as well in coming years. Right now you're looking at about $7k per Powerwall before incentives and while that not far off a whole house generator install it makes more sense in states where you could also use that Powerwall for off-peak charging...no such incentive here in NJ, or at least with JCP&L.

    Caught my first power outage the other day, luckily a short one. Good to know the inverter is being tested to all the production variables early on.

    10-days running as of today....

    Just searching through other favorited systems on PVoutput I sometimes see peaks HIGHER than their rated inverter at times....Is there a bit of overhead on some units and not others?

    Yeah I've noticed mine maxing out at 11.4kW on a few occasions, but it was before I signed up on pvoutput so it was never captured. I was kind of surprise that my 12.21kW system is capable of maxing out the 11.4kW inverter, since I have 3 arrays facing different directions.

    Yes, Some models have a short peak capability slightly higher than their continuous output rating.
    Thanks guys...interesting tech details.

    not all A models can.

    But an interesting aspect is that they are rated on output AMPS. Thus when the grid Voltage is a bit high, almost all inverters can output a bit more watts.

    Email the GPE operations team and copy your sales guy as well.... my progress toward full access I had posted on sunpoweredev post here:
    https://www.solarpaneltalk.com/forum...413#post404413

    Here's what you should request, "Full Access, with Site Owner Access box checked."

    You can try Christine Schneider directly, she's the one who helped me out...... cschneider@greenpowerenergy.com

    Owners should have full owner access which does show the "admin" tab but more limited.

    You can set allerts, view graphs of all monitored spots.

    Installer Admins can re-pair and view the online screen (interact with it actually and do anything through it can can do locally).
    As well as change the layout and strings etc.

    I understand. I don't need or want a larger inverter. I should have clarified that the more production is a result of the size of the arrays. The loss of production at midday for me is less valuable than the production later in the day. It all depends on where one is standing. I am not suggesting that a high DC to AC ratio is optimum for everyone.

    Connecting panels of different alignment to the same inverter can allow longer hours of production
    and a higher DC:AC ratio with little clipping. That is not practical with micro inverters. Bruce Roe

    Part of the difference is you are using the wrong number for the IQ7. It is only a 240w inverter not 250w. So 1.31 ratio instead of 1.26
    you also keep using kW when should be using kWh ...
    Even at 1.31 ratio PV watts is only calculating a teeny tiny difference in annual output vs even 1.00. Therefore think its worth spending extra $300 that installer is asking for 26 iq7+ micros instead of iq7 or is there something else to it I'm missing out on. In other words would I break even on the extra amount theoretically?
