It is designed primarily for load shifting so isn’t big… maybe 1 kWh which you stack like you do inverter/module pairs along a trunk cable to whatever capacity you want. If it’s like their other hardware, I expect it to be well thought out and am looking forward to being an early adaptor.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Bill Dorsett<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Manhattan, KS<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><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:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>Dan Fink<br><b>Sent:</b> Sunday, October 25, 2015 5:33 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> [RE-wrenches] Adding battery backup to Enphase<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Esteemed wrenches;<o:p></o:p></p><div><p class=MsoNormal>I have a new client who has convinced himself the world as we know it will be ending in the next few months.

I was thinking an Outback Radian, and lithium batteries (looking at Iron Edison) as my prediction is they will be mostly sitting idle for the next 10 years at least.
