When I was at Intersolar 2 years ago in Munich I saw Solar Edge's
system.<br>
This article mentioned them as one of their partners.<br>
<br>
This was for Europe's "Self Consumption" program. The solar array
is somewhere<br>
around 400 volts DC, regulated somewhat by the optimizers, and
feeds into the<br>
input of the bi-directional inverter and at the same time, to the
bi-directional<br>
charge controller and into the batteries (48V I think)<br>
<br>
So the charge controller can take from the batteries and feed to
the 400V (ish)<br>
bus and come out the inverter as AC to the grid and of course to
power the house.<br>
<br>
There was a whole bunch of this kind of battery-solar interactive
stuff at that show. <br>
It was a pretty cool thing. They (Germany, etc) want to be able
to offset the utility<br>
usage during peak times to relieve the grid.<br>
<br>
I figured it was just a matter of time before something like this
might show up here.<br>
I think this may be similar except at 400V battery.<br>
<br>
But this new system, with the inverters as small power wise as
they are going to<br>
start out as, will not quite "power your house" ?<br>
<br>
The article I read made it sound like this was something brand
new.<br>
<br>
Imagine, people making their own electricity ? Can't be done !
Can it ?<br>

<p class="MsoNormal">Hi Wrenches,<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I’m sure you’ve seen the Tesla
Powerwall press releases by now:<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal"><a moz-do-not-send="true"

<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">We are already getting calls from
interested homeowners. The product mostly seems like a toy
for wealthy people but nonetheless I would like to be
educated in how it works. <o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">There is mention that the battery pairs
with Solar Edge inverters which makes sense because both
the Powerwall and Solar Edge work off of ~350 VDC. But, I
can’t figure out how off grid operation would work during
power outages. Maybe another battery inverter like a
Schneider Conext is required?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Any thoughts on this product for better
or worse? <o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Best,<o:p></o:p></p>
