I am researching a project to install 2 Powerwall 2s into an existing solar installation on my house. When I had my solar system installed a couple of years ago (27 LG 370 panels with IQ7 microinverters), there were complications surrounding the routing of conduit and placement of the combiner box, etc. near my main panel due to a fireplace and other obstructions. Since I had a 200 amp sub-panel located on the opposite side of the house with plenty of clearance, it was decided to run the solar to the sub-panel instead of the main panel.
I am wondering how this setup might complicate my ability to fully utilize an energy storage system such as the Powerwall. Part of my confusion is due to a lack of in-depth understanding of how the Powerwall works with regard to its interaction with the Gateway, etc.
My primary objective for the battery system is to optimize my electric usage. I live in SCE territory and am on a TOU plan. I want to be able to store energy during lower cost hours to use during the expensive peak hours. Since we don't have that many power outages where I live, having backup is a secondary priority - but would certainly be nice to have. I would prefer to energize the whole house during backup operation. So, I don't believe a backup loads panel will be necessary.
1) Has anyone installed a Powerwall to a sub-panel at some distance from their main panel? If so, what were the challenges/sacrifices for such an installation? I am assuming the Powerwalls need to be placed near where the solar panel outputs come together (in my case, the combiner box).
2) What exactly does the Gateway do and how does it do it?
3) How is the Gateway connected to the Powerwalls? Can this be a wireless connection? If not, what kind of wire would I have to run between the Gateway and the Powerwalls?
Sorry for the long-winded post.
