<p>Hi Joel,<o:p></o:p></p>

<p>The system I designed at the Real Goods Solar Living Center was been
grid-tied and on battery back-up for 13 years now, goes back to the non net-metering
days and 2 meters. I did a whole "house" back-up with 2 SW5548's on
the lighting panel and 2 SW5548's on the plug-load panel. PV is about 11kW and
battery is good for 8 hours of store back-up. We kept one office off of
back-up so we would know when a power failure occurs and energy use could be
cut back a bit. All the usual problems of you see over 13 years - inverter
issues, batteries not liking a life in float, CC failures and so on, but agin
nothing that we would not experience on a typical o-t-g system.<o:p></o:p></p>

<p>Take care old buddy,<o:p></o:p></p>
