[RE-wrenches] Morningstar new battery backup , more comments and opinions

[Jay]

Hi all

I also question this. 
Ok so there is a power outage. If I understand correctly it's a manual disco. 
So now you have be home and know what to do, and you have to remember to turn it back the other way. 
And it's going to be expensive. Their straight disco one is what $1700?

VS. AC coupling which will do it all automatically.

Biggest reason I could see is for the small amount of folks with non AC coupling battery back up inverters. 

I think it's a cool piece of kit, but I don't see it as a big seller.

Peltz power.

The Tesla Powerwall has generated plenty of buzz, even though it's still expensive and unavailable, for battery backup. Seems like smart marketing to me, to have a ready solution to allow a relatively simple add-on package, with batteries, battery-based inverter, and controller/transfer switch, that allows the array to recharge the batteries during an outage. The Radian (or Schneider XW) are good approaches for new systems, but there are thousands of batteryless string-inverter systems out there, and this is a key part of an add-on package. Seems to me it beats an AC-coupled add-on package.
