Would it be possible to configure some Sunny Islands with a Sunny Boy on
the 7.92 kw Sub Array? That might work with the new SB
8000US. <br><br>

The curve ball.....client now wants some back-up capabilities that
include solar......there is a 7.92kw sub-array in the system that may be
part of the solution. Any thoughts?<br><br>

Subject: [RE-wrenches] Couple of Qustions about AGM batteries<br><br>
<br>
<blockquote type=cite class=cite 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>
