    Is there a electrical reason for two+ PowerWall 2s vs PV system size?

    Did you ever get a real answer as to why the SureStart is not compatible? I'm getting the same story from Tesla. I think the SureStart technology may not be compatible with 2 speed compressors (which I have).I have a 7 Kw solar system and am adding 2 Powerwall 2's.

    Arizona Powerwall Installs

    I have a confirmed order dated in November 2016 and have been questioning the reasons for the delay. First it was approval from APS and then the help they are providing to Puerto Rico for their power problems. They stated that there have been no installs in Arizona.

It isn't a double pole double throw switch/relay that...

Since I usually have an excess of solar power every month except January and February; the solar would seem to provide at least 83% of the battery charge. My "tru-up" resets at the end of the...

    Tax credit questions

    Question: I have an existing 7 kW solar system and want to add 2 Powerwall 2 battery backups. Can I apply the 30% Investment Tax Credit to my income tax? It seems like if the Powerwalls are installed at the same time as the solar system, the Investment Tax Credit does apply.

    Powerwall 2: Technical

    My first post here but I've been "reading the mail". I had a site survey by Solar City on April 12 and haven't heard anything yet. I have a deposit on 2 Powerwall 2's and I want a whole house backup. I guess Arizona is too far East to get an early installation. The picture you posted seems to...
