The 400 volt battery output in particular will be the most revolutionary part of the product in my opinion. The Storedge product is their 1<sup>st</sup> gen battery product (I believe) so only time will tell how it works:</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d"><a href="http://www.solaredge.us/groups/us/products/storedge">http://www.solaredge.us/groups/us/products/storedge</a></span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d">I’m not convinced that any of the other lithium products are ready for prime time. They are expensive and I don’t personally want to spend the time or money to experiment with them at this point. That said, we recently commissioned our first dual Schneider XW+ system with AGMs and besides a few hiccups, it looks like a very customizable and clean package. I agree that storage is the future and certainly the reduced size and increased cycling ability of lithiums make them very appealing.</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d">Cheers,</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d">August</span></p><p class="MsoNormal"><span style="color:#1f497d">Luminalt</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><div><div style="border:none;border-top:solid #b5c4df 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""> RE-wrenches [mailto:<a href="mailto:re-wrenches-bounces@lists.re-wrenches.org">re-wrenches-bounces@lists.re-wrenches.org</a>] <b>On Behalf Of </b>Peter Parrish<br><b>Sent:</b> Sunday, January 17, 2016 11:07 AM<br><b>To:</b> 'RE-wrenches'<br><b>Cc:</b> <a href="mailto:peter.parrish@solargnosis.com">peter.parrish@solargnosis.com</a><br><b>Subject:</b> [RE-wrenches] Availability of Powerwall Batteries</span></p></div></div><p class="MsoNormal"> </p><p class="MsoPlainText"><span style="font-size:12.0pt;font-family:"Calibri","sans-serif"">I have a residential client who wants a grid tied PV system with battery backup.
