last point about the Solar Boost IPN product: Once you have
programmed the 2512iX charge controller from the IPN Pro, the
controller retains the information and can be installed as a
stand-alone unit. That means you can have a custom programmed charge
controller for just a little more than the Tristar you are
considering.</font></blockquote>

<div>I am sorry if i seem ungrateful for the many useful ideas that
have been voiced. I suppose I just like to try to oversimplify
things. At present my over-simplification is to say that, for
opportunity charging, the only thing that really matters is not to
exceed the temperature-compensated absorption voltage.
Until now I had imagined that it was dangerous to prolong the
absorption voltage stage. But maybe float is not so important as
making sure that the battery gets enough charge to prevent premature
failure. By the time the charging current has dropped to the
transition current level it is too low to do any damage and can be
prolonged indefinitely (until wind and sun stop anyway). This
would not work in a grid connected situation, but seems to fit for
mine. I am sure you guys will point out if I have got this
wrong.</div>
