<div dir="ltr">Hi Jay - The battery kW rating isn't necessarily set. Assuming a 60 kW-DC PV system, we might have about ~50 kW (or a bit more) of PV inverter rating so I'd by default match the battery inverter rating to that (about 50 kW) if it was AC coupled. If, for example, we go with four SMA 6048-US Sunny Islands as our constraint then we might need to split up some of the PV to be solely grid tied. Long story short, I'm not sure yet.<div><br></div><div>August<br><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Fri, Jan 11, 2019 at 10:09 AM Jay <<a href="mailto:jay.peltz@gmail.com" target="_blank">jay.peltz@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div dir="ltr"></div><div dir="ltr">Hi August </div><div dir="ltr">Did you tell us how many kW of battery inverter you needed?</div><div dir="ltr"><br></div><div dir="ltr">Jay </div><div dir="ltr"><br>On Jan 11, 2019, at 6:40 AM, August Goers <<a href="mailto:august@luminalt.com" target="_blank">august@luminalt.com</a>> wrote:<br><br></div><blockquote type="cite"><div dir="ltr"><div dir="ltr"><div dir="ltr">Thanks All for the ideas. For the battery inverters, I'm most interested in sticking with SMA or Schneider which I've had good experience with in the past. Over the past year and a half our experience has been focused on the Tesla Powerwall with <a href="http://www.cpuc.ca.gov/sgip/" target="_blank">SGIP </a> incentivized projects. Tesla is now allowing up to ten Powerwalls per Gateway which is about 135 kWh of storage - more than enough for most folks! But this particular client doesn't want Tesla and insists on wanting more the 200 kWh of storage. As many of your know, SGIP is not for backup purposes but rather for advanced grid support functionality. I'm curious whether we can program with Schneider XW to meet SGIP requirements and I've been under the impression that we can't with the SMA Sunny Island. Regardless, it might be easiest to just program the inverters for backup only operation and just skip the SGIP all together. </div><div dir="ltr"><br></div><div dir="ltr">Best, August<br><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Jan 10, 2019 at 7:17 PM Darryl Thayer <<a href="mailto:darylsolar1@gmail.com" target="_blank">darylsolar1@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-size:large">Hi, my supplier, just today introduced us to a new product they are selling.
