Elon Musk is known for starting companies that address major challenges in human civilization and taking on big challenges seemingly without fear. These companies are SpaceX ( picking up contracts from NASA and other space programs) , Solarcity ( financing and installing home solar power in the US) and Tesla Motors ( all electric car maker).

So far there has not really been any crossover of the three companies as far as technology or projects but recently Elon has hinted that Tesla which is already building lithium ion batteries for the vehicles may be also making batteries to sell to home owners that install solar pv from Solar city allowing them to make better use of the generated home solar electricity.

During an Tesla earnings call in February, CEO Elon Musk said:

We’re going to unveil the Tesla home battery consumer battery that will be for use in and people’s houses or businesses, fairly soon. We have the design done and it should start going into production probably about six months or so. We probably got a date to have sort of product unveiling, it’s probably in the next month or two. It’s really great. I’m really excited about it.

It is not clear so far whether these batteries will be branded as Tesla or Solarcity (or both)?

    at this point Solar City does not like to do off grid storage of power in their systems. How long before they integrate this into the systems they install, and will they allow a person to reinstall a system to incorporate battery storage? It won’t matter to me as I am totally off grid and have lithium batteries in my system.
