    They also have a model RESU 10 that can be double installed for 20 KWH. They will be available to purchase in North America in early 2017

    I see advertised prices equal to $4200 USD.  Based on specs, that's slightly cheaper than a lead acid T105RE on a $/KWH/cycle basis.

    I am available for custom hardware/firmware development

    Read the warranty on the LG. all 8 pages.....It will be years before the price makes sense comparing to lead acid on cost alone.
    Maintenance and not worring about state of charge may make the LG worth the price in many applications.
    Also, you can't just add the LG to a Schneider or Outback system!  There is another "box" besides the BMS that is internal to the LG.
    Add all of this to a world economy that is really anemic and you can see why it is taking so long for the metal with an atomic number of 3 to make it to primetime in home storage for the masses. Austrailia really is the place it started becuase of their grid. 
    We do not want a Samsung Galaxy in this industry!  We are beta testing outside of LG BTW.
    That was the problem at Samsung in my opinion!
