appraisal here. I have clients that need 24/7 for computer but for only a few lighter
loads and this has worked out well. They had frequent outages and very dirty
power. They had lost a number of pieces of equipment to the surges. We used Outback
with AGM batteries and a grid tie feed and they are very pleased.<o:p></o:p></span></p>

<br>
If the client only expects 24 hour autonomy, you could build/supply an
"uninterruptible power supply" for the police loads only, with no
solar recharge dedicated to that system. This would involve inverter/chargers,
appropriate safety gear & some monitoring, and a battery bank big enough to
carry those loads for the requested 24 hours...and no PV array. <br>
<br>
When the grid comes back up, that will drive recharge of the battery. If the
client had requested, say, seven days of system autonomy that might point back
to connecting up PV to the system, but for 24 hours of ride-through I think
it's all about the battery...or the generator system with auto transfer switch
per William's suggestion.<br>

PS: Seriously, I have seen projects like this and rarely is there a
natural subdivision in the power distribution that allows one to back up a
portion of the loads. Backing up a huge power demand, which I assume this
is, is best done by rotating machinery.<br>

Subject: [RE-wrenches] Couple of Qustions about AGM batteries<br>
<br>
<br>
<br>
<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'>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>
