controller. The customer has some older L-16 batteries mixed with new
and she thinks the controller has damaged her batteries. I am trying to
convince her that the batteries were already damaged and mixing old with new is
a bad idea.</FONT></SPAN></DIV>

class=616120720-23072013><SPAN class=460045719-23072013>I believe the client
started with bad batteries, 6 are 4 years old, 2 are 1 year old. She is
convinced that the CC damaged her batteries. She replaced panels and CC
recently, installing the Tristar. I believe the old PV system charged at
such a slow rate (8 amps) that the battery deficiency was not apparent.
The higher charging rate has emphasized the
problem.</SPAN></SPAN></SPAN></FONT></DIV>
