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 SGIP <http://www.cpuc.ca.gov/sgip/> 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.
