<DIV>William,</DIV>
<DIV>I would agree with generator only if there was the load demand. One thing I
failed to mention is that this will be back-up for lights and communication for
the campus police w/ 24hr autonomy. It looks as though the Sunny Island
route is the most practical at this stage, but I am open for other
suggestions.</DIV>

PM<BR>Subject: [RE-wrenches] Couple of Qustions about AGM
batteries<BR><BR><BR>
<BLOCKQUOTE class=cite cite="" type="cite">We have put together a 850 Wdc
portable stand-alone PV system. It uses a<BR>Blue Sky 3024DiL charge
controller, a pair of SunXtender 250 A-hr AGM<BR>batteries (24 volt
configuration), and a Xantrex Prosine 1000 inverter.<BR><BR>We have been
using this system for powering "events" and getting some good<BR>marketing
from the activities. Everything has worked out well, and the<BR>system is
not being used now and probably won't until March or
April<BR>sometime.<BR><BR>We have let the system fully charge the
batteries through bulk/absorption<BR>and now float. The float conditions
are 26.4 V and 2.0 A at a battery<BR>temperature of 21 deg-C.<BR><BR>My
first question: is it alright to let the batteries float every day
for<BR>the next 6 to 8 weeks, or should I disconnect them from the rest of
the<BR>system until we are ready to use the system again?<BR><BR>My second
question: since the 3024iL can perform an equalization, is there a<BR>safe
equalization procedure for these AGM batteries?<BR><BR>-
