Hi all, Has OutBack licked the multiple stacking UL listing yet? Can we hookup a quad stack now to the grid? We would be looking at doing a 120/240 VAC single phase setup with two inverters per leg.

Hi Joel, 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. Take care old buddy, -jeff o >From the Solar, Wind and Hydro powered office of Jeff Oldham/Regenerative SOLutions ____________________________________________________________ Click now for prescreened plumbing contractors. <http://thirdpartyoffers.juno.com/TGL2132/fc/BLSrjnsPjbmu0npVnrRhoKis5lLsu02 Vn82VT1nwabjQR9VHcoh2f3L7FJG/>
