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.

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.Leave a comment:

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.

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?

Yes, Some models have a short peak capability slightly higher than their continuous output rating.Leave a comment:

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.Leave a comment:

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

full admin is for installers.
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.Leave a comment:

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 RoeLeave a comment:

you also keep using kW when should be using kWh ...Last edited by njdealguy; 09-07-2019, 09:43 PM.Leave a comment:
