I lunched recently with representatives for a major inverter manufacturer. They indicated they were developing a new battery-less inverter featuring a \u201cplug and play\u201d battery upgrade. They indicated they would be marketing this is an \u201ceasy\u201d upgrade from battery-less to battery backup. I told them this transition was not as simple as they described it.

The block diagram presented shows a battery bank, a batter inverter and a critical loads sub-panel. The verbal description they offer of this system and interconnection is: \u201csome wiring.\u201d This is a vast understatement in most cases. Adding a sub-panel and segregating loads is major surgery in a majority of homes, not to mention creating a safe storage container for batteries, interconnecting 600VDC PV feeders, AC Feeders, etc., etc. To pre-bias the customer by saying such a project can be completed in one day makes it really hard to present a realistic bid for what can be a pretty significant project. I liken this to the Tesla hoopla about how easy it is to screw a small box to your garage wall and you will have endless power without reliance on the grid. It\u2019s a lot of over-simplification to sell product, and a disservice to the installing community.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'>I\u2019d like to see a response from Morningstar on this point.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'>William Miller</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Arial","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><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" target="_blank">re-wrenches-bounces@lists.re-wrenches.org</a>] <b>On Behalf Of </b>Chris Mason<br><b>Sent:</b> Wednesday, June 03, 2015 5:03 AM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] Morningstar new battery backup , more comments and opinions</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I'm having trouble understanding the application for this product.
