olar Boost / C40 test [RE-wrenches]

[Doug Pratt]

Excellent work Tump.  It's nice to see when common sense expectations and real
world experience coincide.  4-5% gain is no big deal, but I see that your ambiant
temperture was over 90 degrees, so this was far from ideal conditions for the Solar
Boost.
  This settles it, I'm going to start recommending the Solar Boost controllers with
any sizeable battery-based intertie systems (including my own new shop this
summer).
